We figured out how to sew samsung phoneswhat program is needed for this, etc. In this part, we will analyze how to flash smarts from other brands.

You can flash a smartphone in two ways: through recovery and using a computer. Let's start with the second method - through a computer.

Flash programs

For all phones except Samsung, there are two flasher programs: Flash Tool and Upgrade Download. But how to learn to distinguish which firmware was created for which program?

Consider an archive with two different firmwares. The first firmware is for the Flash Tool, and this is how the contents of the archive look like:

And this is how the archive with the firmware for the Upgrade Download program looks like:

There may be one or more files, but the main one with the extension “pac”.

How to flash a phone using the Flash tool?

The first step is to download the firmware and the flasher. You also need to download drivers for the smartphone, but sometimes they are installed automatically by connecting the smart to the computer.

Now let's move on to the firmware process itself. First, unzip the firmware to a convenient location on your computer. Better on your desktop to make it easier to find. Now launch the Flash tool. The main window of the Flash tool looks like this:

To start the firmware, press the "choose" button next to the Scatter-loading File line. In the window that appears, go to the folder with the firmware, and select the file that is highlighted in the screenshot below:

The firmware files will appear in the flasher. Then click the Download button.

Now turn off the phone and connect it to the computer. The drivers should be installed and the firmware process should begin. If this does not happen, and the phone shows a charging indicator, do the following:

  • Disconnect the phone from the computer;
  • Press the Stop button in the Flash Tool;
  • Now press the Download button again;
  • We connect the phone to the computer via USB cable.

If the problem persists, download drivers for your device and for your operating system on your computer and install them.

At the end of the process, a small window with a green checkmark will appear in the middle. Now you can disconnect your phone from your computer and turn it on.

Firmware via Upgrade Download

The main window of this program looks like this:

To load the firmware into it, click on the gear in the upper left corner. Explorer will open, find the folder on the computer with the unzipped firmware. Select the file with the "pac" extension. After that, press the "Start" button.

Now we connect the OFF phone to the computer via a USB cable. The firmware process will begin.

At the end, a notification or SUCCESS will appear.

Firmware through recovery

The firmware that is installed through the recovery looks a little different.

Only for such firmwares, you need to carefully read the description. The fact is that the firmware looks almost the same, but you won't be able to determine what type of recovery they are for.

A few words about the types of recovery. Recovery can be stock and custom. Stock is a recovery released by the manufacturer, so to speak, official, and is intended only for installing official firmware. are suitable only for custom firmwares, but they, in turn, are also divided into two types: CWM and TWRP.

Now let's move on to the firmware process. First, download the firmware to your phone and save it to the root of the SD card. Next, turn off the phone, then take out the battery and insert it back. We simultaneously hold down the power button and the volume + button. You will find yourself in recovery. It looks something like this:

Scroll up and down with the volume rocker, and select the desired item with the power button. Select the item "apply update from external storage". The entire contents of the SD card will open. Scroll down and select the archive with the firmware. The inscriptions Yes and No will appear, select Yes. The firmware process will begin. After the end, the main recovery menu will appear.

With custom recovery, things are exactly the same. Let's start with the CWM recovery, which looks like this:

Now, briefly about TWRP recovery. It looks like this:

It has touch controls, so it's a little easier to use. Another difference is that it can be in Russian. In TWRP recovery, to start the firmware, you need to click Install (or Install). We select the archive with the firmware and confirm the action.

After firmware

After the end of the firmware, you need to make wipes, that is, reset all data. In stock and CWM recovery, this is done as follows:

  • In the main recovery menu, select Wipe Data.
  • Confirm the action, click Yes.
  • We return to the main menu, select Wipe Cache.
  • Confirm, click Yes.

Wipes in TWRP recovery are done a little differently:

  • Select Wipe from the main menu.
  • Move the slider with a swipe to the right to confirm.

We return to the main recovery window and click Reboot. This is a system reboot.

Now a few words about some things that may happen after the firmware.

  • Long startup

The first launch will always be long, it can take up to 5 minutes. If it takes too long to start and the phone still won't turn on, try the following: remove the battery for 10 seconds, then plug it in and turn it on again.

  • After the firmware, all data remained

After flashing, be sure to reset all settings. Therefore, if the settings have not been reset, and after turning on everything remains the same, make wipes and flash the phone again.

What should be done before flashing?

Required before flashing. Move them to your computer or other USB flash drive. And most importantly, you need to keep all your contacts. This can be done in the phone book using contact import. All numbers will be saved in one file at the root of the SD card, and if necessary, you can always restore them.

Experienced users are often interested in how you can install Recovery on Android. Recovery mode allows you to perform several additional operations on your smartphone.

There are methods that can be applied to flash custom Recovery. These include ROM Manager for ClockworkMod, GooManager for TWRP, Fastboot for devices with unlocked bootloaders, and Flash Image for when other methods don't work.

Which installation method is better to choose

Most smartphones are compatible with several recovery modes, but the most popular are ClockworkMod Recovery (CWM) and TeamWin Recovery Project (TWRP). In addition to the ROM Manager and GooManager applications, which were created specifically for these recovery methods, other programs should also work if they are compatible with the gadget.

There are 3 standard ways to install Recovery:

  • ROM Manager or GooManager;
  • Fastboot;
  • Flash Image.

The ROM Manager and GooManager related methods are the easiest to install ClockworkMod or TWRP. However, these methods require Root access. If you need to install any custom Recovery using command linethen the Fastboot method will do. The main advantage of this method is the fact that it does not even require rooting. It should be borne in mind that the bootloader must be unlocked for this method.

The Flash Image method also allows you to replace the stock Recovery and set any custom recovery mode. This requires Root privileges, a command line emulation application, and the flash_image binary. This saves the hassle of using a computer to manual installation Recover with Fastboot.

The Fastboot and Flash Image methods require special image recovery. The latest version of ClockworkMod and TWRP for a specific gadget can be downloaded from the developers' web pages of these applications.

In some cases, you may need alternative installation methods, for example, if your smartphone does not have a separate partition for recovery mode, since it is built into the kernel boot partition. Many Sony devices fall into this category and Samsung Galaxy... They need a kernel firmware which includes recovery using ODIN or FlashTool.

Alternative way will be needed even if the device was not originally intended for android systems... In this case, a special method for installing ClockworkMod is required. Examples include the HTC HD2 and HP TouchPad. There is no one-size-fits-all guide that covers all methods of setting Recovery Mode, but the standard methods in this guide should work for most smartphones. However, some phone models may require a specific approach, in which case you will need to refer to search engine Google to find instructions for specific devices using it.

Installing CWM Recovery

Now you can go directly to standard methods setting a custom recovery mode. Such operations should be performed with caution. If during the installation process the device is damaged or completely breaks down, then its owner may be denied warranty repair or replacement, since users are not allowed to engage in such manipulations.

Those who are interested in how to install ClockworkMod Recovery should take into account that this is the easiest and most affordable method, which allows you to start the installation from the graphical interface during device boot. In this case, you do not need to download the recovery image and enter any commands. This is the most convenient method for most users. You can try other methods only if CWM did not work. For installation CWM Recovery you need to do the following:

  1. Install ROM Manager on your smartphone. This is an application that allows you to schedule recovery operations during Android boot and has the option to install the latest version of ClockworkMod Recovery.
  2. Launch the newly installed ROM Manager. The first option that the program will offer should be called Flash ClockworkMod Recovery. You must click on it and follow the instructions.
  3. You have to wait until the system reboots and the latest version of the program is installed. Do not restart manually.
  4. After rebooting the system and starting the operating system, you need to make sure using the ROM Manager that the latest version of CWM Recovery is installed. All available updates must be installed. In case of occurrence new version you must install it following the instructions.

other methods

Install TWRP Recovery using GooManager:

  1. Install GooManager on your gadget. This application allows you to install firmware and mods posted on the official Goo website, as well latest version TWRP Touch Recovery.
  2. Launch GooManager as soon as it is ready.
  3. Enter the menu and select Install OpenRecoveryScript. Answer affirmatively to all questions in the dialog boxes and grant the application access to Root.
  4. Wait for the program to download the latest TWRP update for the device and install it.
  5. After installing Recovery, you need to make sure that the process was successful. To do this, you need to boot through recovery mode. This can be done using the GooManager by clicking Menu and selecting the Reboot Recovery option.

And one more way, how to install custom Recovery. You will need to download the most recent recovery image that fits your device from the ClockworkMod Recovery or TWRP download page.

It is very important that this file is compatible with devices of a certain brand. For example, if you are using a Digma device, you need to make sure it is supported. Otherwise, the firmware may fail and render the device unusable.

To install any custom recovery mode using fast bootloader, the computer must have ADB and Fastboot. After the installation is complete, you will need to do the following:

  1. Copy the recovery image to any convenient location on your computer (it is desirable that the path to the file is not too long). You can put it in the root directory of the C drive and not create a special folder. The recovery image must have an IMG extension. If it is inside a ZIP archive, you should unpack it.
  2. Connect your Android device to personal computer via USB.
  3. Wait until Fastboot USB appears on the screen.
  4. Launch Command Prompt and enter fastboot flash recovery c: \\ recovery.img. Keep in mind that the path to the file looks like this because the image is located in the root folder of the C drive. If the image is located in a different location, you need to specify the appropriate path.
  5. Wait until the process is complete, then restart the device.

If everything was done correctly, the modified recovery mode should work.

How to install recovery on Android

Today, custom recovery, that is, a recovery environment for Android devices, offers much more options than firmware. Therefore, below we will consider a step-by-step installation using the example of the popular TWRP (Team Win Recovery Project).

How to install recovery on Android - preparing for the firmware process

It is important to know that (in some cases, for example, when the power is turned off, discharged, disconnected from the wire), the process of installing custom recovery can lead to a decrease in the device's performance, errors, failures and other dysfunctions. In this case, the device loses the remaining warranty period, so all manipulations should be done with the utmost care, at your own risk. By default, it is assumed that the bootloader is already unlocked on the smartphone or tablet, and the Android SDK Platform Tools are installed. If the device meets the described conditions, do the following:

  • We download the appropriate version of the recovery for Android, which corresponds to the model of our smartphone / tablet.
  • Save the file to the Platform-tools folder with the Android SDK (you can choose any other location, but this will make it easier to specify the path for further commands).
  • Turn on USB debugging.

Installing third-party recovery on Android

Now you can start downloading the custom recovery environment software package to your device. This procedure assumes the use of an operating room windows systems (version is not fundamentally important):

  • switch to "fastboot" mode: for some devices there may be a different sequence of pressing the buttons, but basically you need to press and hold "- sound" and the power button until the menu appears;
  • the next step is to connect the device via USB to the PC, after making sure that there is a sufficient amount of charge on the first device;
  • go through the computer to the SDK Platform-tools folder;
  • press Shift and right-click on an empty space at the same time;
  • select the item "Open command window";
  • enter the command fastboot flash recovery recovery.img, send it for execution with the Enter button (explanation: in place of recovery.img there must be a path to the file of the same name; if it is located in the tools folder, then enter the name "as is");
  • after the notification of successful completion appears, the device can be turned off.

When the TWRP installation is complete, there will still be a fastboot menu on the smartphone / tablet screen. To test the just received custom:

  • select the item " Recovery Mode», Moving through the list with the volume buttons and confirming actions by pressing the power supply;
  • after the initial login, select the language and operation mode - read-only or "allow changes";
  • if you select the first option, custom recovery will disappear after the next reboot;
  • choosing the second will leave TWRP on the system partition;
  • you can also check the box "Do not show this again at boot".

The main custom firmware menu will allow you to flash ZIP files, install third-party firmware, back up or restore files from a backup, reset to factory settings with complete data destruction.

CWM Recovery Android - Custom Recovery Installation

Since the topic android firmware devices is very relevant, I decided to write about installing CWM Recovery on an Android smartphone or tablet. There are several ways to do this at once: for some, all actions are performed on the device itself, but this requires root rights, while for others, a computer is used when installing custom recovery. Use whatever you find easier or more convenient.

Method 1. Installing CWM Recovery via ROM Manager

The first way to flash Recovery is to use the ROM Manager program, which we already talked about in the article: how to flash Android. This application has a separate item that allows you to install ClockWorkMod Recovery in a couple of minutes.

I want to note right away that ROM Manager requires root rights... You can read how to get them here and here.

After that go to official page https://clockworkmod.com/rommanager and see if your device is on the list of supported.

1. Now open ROM Manager and select the first item "Recovery Setup".

2. In the next window in the "Install or update Recovery" section select "ClockworkMod Recovery".

4. At the bottom, click on "Install ClockworkMod".

5. The download process will begin. When good internet connection, it lasts a couple of seconds.

6. At the end of the download, you will be asked to grant root access to the application. Select "Provide".

7. That's it! You will see a notification “Successfully flashed ClockworkMod recovery!”. Just click OK.

This is how easy it is to flash the CWM Recovery through the ROM Manager. Now you can open it and find new items in it that were not in the standard one.

Method 2. Install custom Recovery on Android using the FastBoot utility

All the steps described below are similar to installing TWRP Recovery: go to the article.

We will now use the classic installation method custom recovery via the FastBoot utility for Windows. It is included in the Android SDK, the archive of which must be downloaded from the official site http://developer.android.com/sdk/index.html (go to the bottom of the page and download "tools_version-windows.zip"). You will also need Java and drivers (read more →).

Unzip the folder to the "C:" drive - there will be "tools" inside, and the file "android" in it. Start it up.

Select "Android SDK Platform-tools" and click "Install package".

Check the “Accept License” box and then click “Install”.

When the installation is complete, "platform-tools" will appear in the "tools_version-windows" folder, and it contains "fastboot" and "adb". They will be useful to us further.

UPD: The "platform-tools" folder on my computer is located in a different directory than yours. The fact is that this article was written even when the installer existed for the Android SDK. Starting from the 25th version, the installation is carried out only from a ZIP archive: because of this, part of the instructions had to be edited. Therefore, the path to ADB and Fastboot is different from mine, everything else remains unchanged.

If you have a Sony, HTC, Nexus, Huawei or LG device (some models), then Bootloader is blocked. How to unblock it is described on our website:

  • For HTC: method 1, method 2
  • For Nexus: instruction
  • For Sony: instruction

Let's start the Recovery firmware:

1. First of all, go to this page and download the version of the file "recovery-clockwork.img" for your device. Note that there are both touch and classic versions for most devices. Download the one you like best.

2. Now place the CWM recovery file in the "platform-tools" folder. I also renamed it to "recovery.img" (you will see why later). I recommend that you do the same.

3. Connect your tablet or smartphone to your computer using USB.

In this case, the device must be booted into fastboot mode. Usually, to do this, on the turned off device, you need to hold down the key combination: Power on + Volume down. But this combination may differ depending on the device manufacturer.

UPD: it is much easier to switch to fastboot mode as follows: turn on USB debugging on the device, go to the command line (in point 4 just below it is described how to get into it) and enter the commands in sequence, while after each press "Enter".

cd path to "platform-tools"

adb reboot bootloader

I got it like this:

Your path will look different. If you followed exactly the instructions, it will exit (in any case, see the path in the appropriate line of the Explorer):

cd \\ tools_r25.2.3-windows \\ platform-tools

In the screenshot you can see how I entered the same commands. As a result, the device will boot into fastboot mode.

4. Now open the command line (or skip this item and continue working with it, if you just transferred Android to fastboot mode through it). The easiest way to get there: press the key combination "Win" + "R" and enter:

Then click “OK”.

5. You will be taken to the command line.

6. Now you need to specify the path to the folder with the firmware. Enter the following command to navigate back to the folder.

Press Enter.

7. My path to the recovery folder is "C: \\ Program Files (x86) \\ Android \\ android-sdk \\ platform-tools". So I enter (you write yours):

cd Program Files (x86) \\ Android \\ android-sdk \\ platform-tools

And again press "Enter".

8. It remains to enter:

fastboot flash recovery recovery.img

"Recovery.img" is the name of the file being flashed. Remember I advised you to rename the file from recovery? We did this for convenience, so as not to enter something like "recovery-clockwork-6.0.4.7-flo.img".

After entering this command, press "Enter" again.

9. As a result, we get the following message.

Congratulations! You have successfully installed custom recovery (CWM) with Fastboot utility!

Method 3. Flash Recovery through the Rashr application

This method is also incredibly simple and convenient, but requires root rights. Their receipt is written at the beginning of the article in "Method 1".

1. Install Rashr - Flash Tool application with Google play, open it and grant Root rights.

2. Select "CWM Recovery" from the list of options.

3. Then the program will display a list of available Recovery for your device. In my case, Rashr showed 2 options: ClockworkMod with support for taps on the screen and the classic option (controlled by the volume and power buttons).

4. When prompted to download, click Yes.

5. Then the download of CWM Recovery for your Android smartphone or tablet.

6. At the end, a notification will appear that the firmware was successful and now you have a modified recovery installed. You can reboot into it and try it out. To do this, click "Yes".

Perhaps this installation method can be called the simplest. The only thing that is needed for him is the presence of root rights.

Method 4. Installing Recovery on Samsung in Odin

If you have a Samsung device, you can install ClockWorkMod Recovery on Android using the proprietary Odin utility. Here I will briefly explain what to do. I recommend reading our article: how to flash an Android tablet, samsung smartphone... In it detailed information about using Odin.

1. Find and download recovery for your phone or samsung tablet.

2. Connect the device to a PC via USB and put it in the boot solution. How to do this is written in the full article at the link above.

3. Open Odin and click on "AP" (in some versions of Odin this field is called "PDA").

4. Click the "Start" button and wait for the firmware to complete.

That's all! Hope you found this article helpful! If you have any questions, leave them in the comments.

TWRP Recovery how to install? TWRP Recovery download for android

Hello everyone! In this article, we will talk about TWRP Recovery. Let's start with the advantages over perhaps its main rival, ClockworkMod, then we will consider the purpose and functionality of this utility, then we will give an extended description of all menu items. And of course, we'll figure out where to download and install TWRP Recovery. And at the end, a bonus will describe the process of flashing an android smartphone using this utility.

Before you start reading the instructions for TWRP Recovery, I want to note that most of the users prefer to use this particular recovery due to the fact that, compared to ClockworkMod, it has the following advantages:

  • More user-friendly touch interface
  • Function for setting some options.
  • A transparent way of choosing what we want to include in backup
  • Batch installation support zip files
  • Lock the screen by pressing the power button
  • S Pen support on Galaxy Note tablets and phones

TWRP Recovery is a much more powerful system recovery utility (menu) than the factory one, which allows you to make full backups of the entire device system, install on it software, firmware, kernels and much more, which usually does not allow TWRP factory recovery, is installed in a special system partition of the internal memory of the tablet or phone, in place of the factory recovery. TWRP Recovery can help you out in some seemingly hopeless situations. Even if your tablet or phone stopped booting, in many cases, using TWRP, you can restore the system from a backup, with all its settings and applications.

Here is a rough list of what you can do with TWRP Recovery:

  • Install custom firmware and unofficial kernels
  • Install factory system updates, add-ons and fixes
  • Connect to a computer via USB, in removable storage mode
  • Create a full backup of the current firmware and its individual parts (system, settings, applications)
  • Recover a device from a previously created backup
  • Reset to factory settings (Wipe - data / factory reset), clear cache (wipe cache), clear dalvik-cache (wipe Dalvik-cache), clear battery statistics (wipe battery stats)
  • Create partitions on the memory card and format them
  • Execute terminal commands
  • Work with files on your device

For many smartphones and tablets, installing TWRP Recovery (download) is a fairly simple procedure, you just need to install a program such as GooManager from the Market and select the "Install OpenRecovery Script" item from its menu:

For many devices, such as Nexus tablets and smartphones, there are separate utilities like Google nexus 7 Toolkit. Also, TWRP Recovery can be installed using the adb program.

There are several ways to load your tablet or phone into TWRP Recovery.

1. Using a special program, such as GooManager, by selecting "Reboot Recovery" - "Load Recovery Mode" from its menu.

2. By pressing a certain key combination when turning on the device. This combination depends on the device model. On many devices, you can get into recovery by pressing the volume down and power on buttons at the same time when they are turned on.

3. Using the ADB program. If you configured a connection to a computer using the ADB program, you can load your tablet into recovery using the command: adb reboot recovery

  • After loading your tablet or phone into TWRP Recovery, you will first of all see its main menu

  • In all submenus, you can return to the previous menu by pressing the return button located at the bottom (smartphone) or upper right (tablet) part of the screen.
  • At the top of the screen, you see the battery percentage and the current time.

The purpose of the main menu items:

1. Install - installing firmware and add-ons

  • This is one of the most frequently used TWRP Recovery items.
  • With its help, you can install both official and unofficial (custom) firmware, install kernels, themes and other software, which should be in a zip file located on the built-in memory of your device.
  • After selecting a file, you will be taken to the next menu, where you can choose to add the next file to the firmware queue (Add More Zips button) or start flashing the selected file using the slider located at the bottom of the screen.
  • The Zip Signature verifications option enables the signature verification mode of the zip file.
  • The Force MD5 check on all Zips option enables MD5 checksum checking for all zip files installed on the device.

2. Wipe - clear and reset to factory settings

Installing custom recovery on Android

By default, all Android devices have a recovery mode called Recovery. It can be used to roll back the operating system to the standard settings, install official add-ons and fixes. If this is not enough for you and you want to install third-party firmware, kernels and utilities on your device, then the factory recovery needs to be replaced with a custom one.

The most popular custom recoveries for Android are Clockworkmod Recovery (CMD) and TeamWin Recovery (TWRP). The main difference between one program and another is the presence of touch control in the latter. As for the functionality, the software offers approximately the same list of options:

  1. Installation of unofficial patches, firmware;
  2. Connecting the device to a PC in ADB mode and instead of a removable drive;
  3. Formatting, creating, merging partitions in the internal memory of the device;
  4. Clearing software cache and battery summary;
  5. Create backup copies of the system.

Having studied the methods below, you can easily install custom recovery on Android. You need to get Root rights before carrying out work.

TWRP installation methods

You can install TWRP recovery using a special software developer utility (TWRP Manager), third-party software designed for flashing recovery, and Android Debug Bridge (ADB).

Your first step will be to download TWRP Manager from the Play Store and install the application on your device. The utility must be opened to give rights to Root access. Then:

  1. in the menu that appears on the left, select "install twrp";
  2. a window will appear in front of you where you need to select the device and the version of the recovery that you want to install;
  3. after selecting all settings, click “install recovery”;
  4. program in automatic mode downloads recovery and installs it;
  5. if you want to install a specific version of recovery that you downloaded in advance, then you need to save recovery.img and select it through the "select img file" item.

ADB as a way to flash recovery

This solution with reinstalling the recovery is suitable for advanced PC users. To carry out the manipulations, you will need an Android device, a computer and a USB adapter. First you will need to install the Android SDK with all packages along with the Google USB Driver. Thereafter:

  1. save the TWRP version supported by your smartphone to your computer Recovery.img;
  2. rename the recovery file to twrp.img, save it to the root memory of your device.

Connect your device to your computer using USB. Start the command prompt of the PC operating system (cmd on Windows). Write the following lines in it:

  1. cd C: \\ android-sdk-windows \\ platform-tools \\ adb;
  2. su dd if \u003d / sdcard / twrp.img of \u003d / dev / block / mmcblk0p34.

After that, restart your device.

CMD installation methods

You can install CMD with by Rom Manager, FastBoot mode or third-party utilities for firmware recovery.

Installing CMD using Rom Manager

  1. Download Rom Manager from Play Store and install it on your device. Do not forget to give her Root access rights.
  2. After starting the program, a window will appear, including several sub-items. You will need to go to the "Recovery Setup" tab.
  3. A new window will appear. There select CMD. After that, you will need to select the device model on which the recovery will be installed.
  4. After that, another window will appear where you must confirm your actions.

CMD installations in FastBoot mode

To reflash a device with Android in this way, you will again need to download the Android SDK, USB drivers for your smartphone / tablet. Save the recovery file from the CMD website, rename it to update.img, save it to the platform-tools folder located in the installed Android SDK directory. Then activate USB debugging mode on your Android device.

Run Command Prompt and enter the following commands:


If everything goes well, a corresponding notification will appear on the command line.

Installing CMD and TWRP via Flashify

As we mentioned earlier, they install custom recovery for Android with third-party utilities. One of them is Flashify. A distinctive feature of the program is compatibility with many models of smartphones and tablets. You need to install software on the device and allow it to use Root rights.

  1. From the main screen of the running application, select "Recovery Image".
  2. A window will appear in front of you with the choice of the version of the recovery and the choice of the device model (if you have not downloaded the program in advance).
  3. After the desired version of the recovery is saved in the device's memory, click on "YUP!"
  4. Flashify will install the program, automatically reboot the device.

Since the topic of firmware Android devices is very relevant, I decided to write about installing CWM Recovery on an Android smartphone or tablet. There are several ways to do this at once: for some, all actions are performed on the device itself, but this requires root rights, while for others, a computer is used when installing custom recovery. Use whatever you find easier or more convenient.

Method 1. Installing CWM Recovery via ROM Manager

The first way to flash Recovery is to use the ROM Manager program, which we already talked about in the article:. This application has a separate item that allows you to install ClockWorkMod Recovery in a couple of minutes.

I want to note right away that the ROM Manager requires root rights. How to get them can be read and.

After that, go to the official page https://clockworkmod.com/rommanager and see if your device is in the list of supported ones.

1. Now open ROM Manager and select the first item "Recovery Setup".

2. In the next window in the "Install or update Recovery" section select "ClockworkMod Recovery".

4. At the bottom, click on "Install ClockworkMod".

5. The download process will begin. With a good internet connection, it takes a couple of seconds.

6. At the end of the download, you will be asked to grant root access to the application. Select "Provide".

7. That's it! You will see a notification “Successfully flashed ClockworkMod recovery!”. Just click OK.

This is how easy it is to flash the CWM Recovery through the ROM Manager. Now you can open it and find new items in it that were not in the standard one.

Method 2. Install custom Recovery on Android using the FastBoot utility

All steps described below are the same as installing TWRP Recovery:.

Unzip the folder to the "C:" drive - there will be "tools" inside, and the file "android" in it. Start it up.

Select "Android SDK Platform-tools" and click "Install package".

Check the “Accept License” box and then click “Install”.

After the installation is complete, in the "tools_ version-windows "" platform-tools "appears, and it has" fastboot "and" adb ". They will be useful to us further.

UPD: The "platform-tools" folder on my computer is located in a different directory than yours. The fact is that this article was written even when an installer existed for the Android SDK. Starting with the 25th version, the installation is carried out only from the ZIP archive: because of this, part of the instructions had to be edited. Therefore, the path to ADB and Fastboot is different from mine, everything else remains unchanged.

If you have a Sony, HTC, Nexus, Huawei or LG device (some models), then Bootloader is blocked. How to unblock it is described on our website:

  • For HTC:,

Let's start the Recovery firmware:

1. First of all, go to this page and download the version of the file "recovery-clockwork.img" for your device. Note that there are both touch and classic versions for most devices. Download the one you like best.

2. Now place the CWM recovery file in the "platform-tools" folder. I also renamed it to "recovery.img" (you will see why later). I recommend that you do the same.

3. Connect your tablet or smartphone to your computer using USB.

In this case, the device must be booted into fastboot mode. Usually, to do this, on the turned off device, you need to hold down the key combination: Power on + Volume down. But this combination may differ depending on the device manufacturer.

UPD: it is much easier to switch to fastboot mode as follows: turn it on on the device, go to the command line (in point 4 just below it is described how to get into it) and enter the commands sequentially, while after each press "Enter".

cd path to "platform-tools"

I got it like this:

Your path will look different. If you followed exactly the instructions, it will exit (in any case, see the path in the appropriate line of the Explorer):

cd \\ tools_r25.2.3-windows \\ platform-tools

In the screenshot you can see how I entered the same commands. As a result, the device will boot into fastboot mode.

4. Now open the command line (or skip this item and continue working with it, if you just transferred Android to fastboot mode through it). The easiest way to get there: press the key combination "Win" + "R" and enter:

Then click “OK”.

5. You will be taken to the command line.

6. Now you need to specify the path to the folder with the firmware. Enter the following command to navigate back to the folder.

Press Enter.

7. My path to the recovery folder is "C: \\ Program Files (x86) \\ Android \\ android-sdk \\ platform-tools". So I enter (you write yours):

cd Program Files (x86) \\ Android \\ android-sdk \\ platform-tools

And again press "Enter".

8. It remains to enter:

recovery.img

"Recovery.img" is the name of the file being flashed. Remember I advised you to rename the file from recovery? We did this for convenience, so as not to enter something like "recovery-clockwork-6.0.4.7-flo.img".

After entering this command, press "Enter" again.

9. As a result, we get the following message.

Congratulations! You have successfully installed custom recovery (CWM) with Fastboot utility!

Method 3. Flash Recovery through the Rashr application

This method is also incredibly simple and convenient, but requires root rights. Their receipt is written at the beginning of the article in "Method 1".

1. Install the Rashr - Flash Tool application from Google Play, open it and grant Root rights.

2. Select "CWM Recovery" from the list of options.

3. Then the program will display a list of available Recovery for your device. In my case, Rashr showed 2 options: ClockworkMod with support for taps on the screen and the classic option (controlled by the volume and power buttons).

4. When prompted to download, click Yes.

5. Then the download of CWM Recovery for your Android smartphone or tablet will start.

6. At the end, a notification will appear that the firmware was successful and now you have a modified recovery installed. You can reboot into it and try it out. To do this, click "Yes".

Perhaps this installation method can be called the simplest. The only thing that is needed for him is the presence of root rights.

Method 4. Installing Recovery on Samsung in Odin

If you have a Samsung device, you can install ClockWorkMod Recovery on Android using the proprietary Odin utility. Here I will briefly explain what to do. I recommend reading our article:. It contains detailed information on using Odin.

Basically, updates and new versions of the Android OS are installed over the air (via Wi-Fi) or via a computer using a proprietary utility. But what to do when you want to install a cool firmware, but it is not on the official website of the developer? In this case, the recovery menu will help, Recovery, which is in almost every mobile gadget on Android. It can be used to carry out many system operations, including installing any custom firmware. Next, we will consider what a recovery mode is and how to flash Android through recovery with a step-by-step algorithm of actions.

Probably every owner of an Android phone or tablet has heard about Recovery mode. This is a special diagnostic menu, installed separately from the OS and hidden from users by developers. It can be compared to the BIOS for desktop computers or laptops. Since stock recovery is used to a greater extent to test the performance of various modules, functions of a mobile device. Also, with its help, you can perform various system operations, for example, reset to factory settings and format selected sections of memory.

Type of stock Recovery

But in this case, we are interested in installing custom assemblies, which is available only for third-party Recovery. They are created by the huge community of developers of the operating system from Google, and their capabilities are much wider in comparison with stock. Installing a new recovery is essentially similar to flashing the stock kernel (OS) on a phone. Only in this case, the user switches to the TWRP or Clockwork Mod mode. Note that a prerequisite for installing third-party recovery is to obtain administrator rights (root access).

How to enter recovery mode

To reflash Android, the first step is to enter recovery mode. To do this, you need to turn off the device and then enter the required combination of hardware keys. Depending on the manufacturer mobile device, it may vary, but the most common ones are:

  • Power / lock buttons + volume down.
  • Home key + Power button + Volume up.
  • Same as the previous point, but there is no volume button.

More accurate and detailed instructions how to start the recovery menu can be found on the developer's official website. It is necessary to hold down several keys at the same time and hold them until a green robot appears on the screen. The whole process is clearly presented in the video, which you can watch below.

Algorithm of actions

And so, let's get down to the most interesting. The algorithm of actions for flashing an Android smartphone through the recovery mode is quite simple and looks like this:

  • Find and download the required firmware version to the memory card in the form of a zip archive.
  • Turn off the mobile phone, enter the recovery mode according to the instructions presented in the previous section.
  • In the menu that appears, select the Wipe / Factory reset item to return to the factory settings (if necessary). Thus, you can restore the parameters of an incorrectly working OS.
  • To install a new firmware, select the "Install" item (located in the upper left corner).
  • Specify the path to the directory of the archive with the firmware and start the process.

After that, the process of installing the new firmware on your smartphone or tablet will automatically start. When finished, a corresponding notification will appear on the screen and you can restart your mobile device. To do this, select the item "Reboot" and then "System".
The entire firmware process is clearly demonstrated in the video below.

Recovery firmware

As mentioned above, the standard recovery menu is designed to diagnose sensors and functions of a mobile device. It can also be used to install official updates... But to use custom firmware, you need to reflash the recovery itself in the phone. This requires TWRP or CWM Recovery, which can be installed using a special utility Rashr - Flash Tool. Note that before installing it on your phone, you need to obtain administrator rights.

The program interface looks as simple as possible. The user only needs to follow the installation instructions by clicking on the "next" button. If CWM Recovery is already installed in the mobile phone, the program will offer to perform standard functions: flashing or resetting to factory settings.
