How to install TWRP Recovery on Android - step-by-step instructions. What is recovery in Android (stock and custom)
Anyone who takes the first steps in learning the procedure for flashing Android devices initially pays attention to the most common way of carrying out the process - flashing firmware through recovery. Android Recovery is a recovery environment that almost all users of Android devices have access to, regardless of the type and model of the latter. Therefore, the method of flashing firmware through recovery can be considered as the easiest way to update, change, restore or completely replace the device’s software.
Almost every device running the Android OS is equipped by the manufacturer with a special recovery environment, which provides, to some extent, including ordinary users, the ability to manipulate the internal memory of the device, or more precisely, its partitions.
It should be noted that the list of operations that are available through the “native” recovery installed in devices by the manufacturer is very limited. As for the firmware, only official firmware and/or updates are available for installation.
In some cases, through factory recovery, you can install a modified recovery environment (custom recovery), which in turn will expand the capabilities of working with firmware.
At the same time, it is quite possible to carry out the main actions for restoring functionality and updating the software through factory recovery. To install official firmware or updates distributed in the format *.zip, perform the following steps.
How to flash a device through a modified recovery
Modified (custom) recovery environments have a much wider range of capabilities for working with Android devices. One of the first to appear, and today a very common solution, is the recovery from the ClockworkMod team - .
Installing CWM Recovery
Since CWM recovery is an unofficial solution, you will need to install a custom recovery environment on your device before use.
- For Samsung devices, in most cases the application is used.
- For devices built on the MTK hardware platform, the application is used.
- The most universal method, but at the same time the most dangerous and difficult, is flashing the recovery via . The steps taken to install recovery using this method are described in detail at the link:
Firmware via CWM
Using a modified recovery environment, you can flash not only official updates, but also custom firmware, as well as various system components represented by cracks, add-ons, improvements, kernels, radios, etc.
It is worth noting that there are a large number of versions of CWM Recovery, so after logging in on different devices you can see a slightly different interface - background, design, touch controls may be present, etc. In addition, some menu items may or may not be present.
The examples below use the most standard version of the modified CWM recovery.
At the same time, in other modifications of the environment, when flashing the firmware, items are selected that have the same names as in the instructions below, i.e. A slightly different design should not cause concern to the user.
In addition to design, the management of CWM actions differs in different devices. Most devices use the following scheme:
- Hard key "Volume+"— move one point up;
- Hard key "Volume-"— move one point down;
- Hard key "Nutrition" and/or "Home"— confirmation of choice.
So, the firmware.
Firmware via TWRP Recovery
In addition to the solution from the ClockworkMod developers, there are other modified recovery environments. One of the most functional solutions of this kind is. How to flash devices using TWRP is described in the article:
This is how Android devices are flashed through recovery environments. It is necessary to take a balanced approach to the choice of recovery and the method of installing them, and also flash only the appropriate packages obtained from reliable sources into the device. In this case, the process proceeds very quickly and does not cause any problems later.
Nowadays, you won’t surprise people with a smartphone. Almost every 3rd person in Russia has such a gadget. Few people buy expensive devices, only the wealthy part of society. Therefore, most have gadgets on a budget basis. After a short period of time, when using it, the phone's memory runs out, the RAM memory becomes clogged, or other problems arise. Then people start experimenting with their phones, deleting something or installing some programs for system tasks, etc.
An unknowing person soon turns his smartphone into a brick. And to prevent this from happening, there are special forums where they talk about any gadget and give various step-by-step instructions for solving problems with your device.
At the moment, you are on just such a forum. In this article, I would like to tell you, as a beginner, how to easily and quickly flash a custom Recovery firmware for your smartphone. That is, replace (install) a modified one instead of the native, official Recovery.
Why are modified recoveries installed? Firstly, due to their various functions, you can perform various system actions with the gadget. Next, you can install any unofficial firmware on your phone (modified firmware). Also do Backup your device for further recovery. The following modified recovery firmwares exist: CWM Recovery, TWRP Recovery.
In this article, I will not explain in detail about modified firmware for recovery. There is a large amount of information on this issue on the Internet.
Personally, I use the second type of firmware, namely TWRP Recovery.
In order to quickly and without any hassles install one of these firmwares, we will use the program - Mobileuncle MTK Tools. This program is only suitable for those phones (smartphones) that run on a processor MTK.
To further perform actions with the phone, you must have Root rights, you must become the administrator of your gadget. How to do this? Our forum will also help you with this problem. There is a whole thread on this issue.
And lastly, you must download the recovery file itself, in the following format: recovery.img
.
Remember!!! Each smartphone needs its own recovery file.
Preparatory part
1. We get Root rights to the phone.2. Download the archive with the program to your computer ().
3. Unpack the archive onto your computer. Read the instructions in the archive.
4. Drop the program onto your phone into the root of the CD card or into the created folder.
5. Download the file recovery.img, for your phone!
6. Upload the file recovery.img to the root of the CD card
This completes the preparatory part. Next we move on to the step-by-step installation. Once again, this type of installation is suitable for any beginner in this not difficult task!
Installation
1. Install the program Mobileuncle MTK Tools on your phone. After installation, an icon will appear, a green smiley face in a mask (ToolHero).
2. Launch the program ToolHero(you can read the contents).
3. An update window will pop up. Do not update the program under any circumstances!
4. Click on the Recovery tab.
5. The program will find your file itself recovery.img on your device and show it to you.
6. Click on the Install button.
7. The modified recovery will be installed on your Android system.
8. Through the program ToolHero, reboot into the modified recovery menu.
This completes the installation of the modified recovery.
Tip: First of all, as soon as you go into Recovery, make a backup of your phone's data.
Warning!!! In the Recovery menu, I advise you not to press anything! Otherwise, there may be problems with the phone! Or it will turn into a brick. Just visually familiarize yourself with the menu and tabs. You can use it only after studying each menu tab. Find out what each tab does and how it works. Only after this can you use the program in full. Material for familiarizing yourself with the modified recovery can be found on forums on the Internet. If you don’t know where to get the material, write to me and I’ll help!
Good luck! Successful actions!
By default, all Android devices have a recovery mode called Recovery. With its help, you can roll back the operating system to 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.
Custom recovery: what to choose
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 controls in the latter. As for functionality, the software offers approximately the same list of options:
- Installation of unofficial patches and firmware;
- Connecting the device to a PC in ADB mode and instead of a removable drive;
- Formatting, creating, merging partitions in the internal memory of the device;
- Clearing software cache and battery life summary;
- Creating backup copies of the system.
After studying the methods below, you can easily install custom recovery on Android. You need to obtain Root rights before carrying out work.
TWRP Installation Methods
- using the ROM Manager program, selecting the “Load Recovery mode” section on its initial page;
- by pressing the keys simultaneously after turning off the device. Combinations may vary depending on the model and manufacturer of the device. In most cases, these are the volume down and power buttons;
- using the ADB program using the adb reboot recovery button.
Possible difficulties
During the installation of an alternative Recovery Mode, in particular CWM, various difficulties and errors may arise. Which of them are the most common and how to solve them?
CWM Recovery does not recognize the memory card
CWM makes it possible to update your phone using an archive. When opening Recovery, the user sees a message that the flash card cannot be mounted. After installing another card, even with less memory, the problem disappears. The reason lies in the Windows system itself. The fact is that it diverges from card formatting standards. To format formatting in accordance with the specification of SD/SDHC/SDXC flash cards, and not just in standard form, it is recommended to use specialized software, for example, SD Formatter.
The SD Formatter program allows you to correctly format the SD card
CWM does not see the internal memory of the device: problem solution
When the recovery files are located on the internal memory, and therefore can only be recovered from there, a problem may arise. When you connect the USB cable to the PC and enable “USB Debugging”, the program reports that the Android device is not detected and you need to enable “USB Debugging”.
To solve this problem:
- Connect the device as a camera, not a storage device. If there are other options available, choose them.
- Install universal drivers.
- Find a more suitable Recovery program for your device.
Recovery menu doesn't work
If when you launch the alternative recovery mode (volume + Home button or power) a picture appears with a lying robot, then the recovery was flashed, but when you restarted the device it was overwritten by the stock Recovery.
The problem is solved as follows.
- Before flashing the Odin3 program, you need to uncheck the Auto restart checkbox and disconnect the cable after flashing. From Download mode on the device, go to recovery mode by pressing the volume up + home screen + power keys in sequence until the recovery menu appears. So you should get into the custom recovery menu anyway.
- In it, select Reboot system now and then check Yes. This action will overwrite the stock recovery with a custom one and the “No command” error will be corrected.
Flashing a new Recovery mode means acquiring new functionality. Firmware methods vary in complexity, but ironically, the simplest of them require access to Root, that is, device administrator rights. When choosing a firmware method, you need to be guided by the phone model first. Rom Manager is not suitable for all devices. For HTC, the FastBoot method is more suitable, while for Samsung it would be more correct to choose Odin.
Users who are dissatisfied with the operating system on their mobile device are often interested in how to flash Android through Recovery. The installation procedure for most known firmware (ROM) looks identical. The guide below will help you download any ROM or app from a ZIP archive to your Android device using the recovery feature.
Preparing for firmware
The firmware procedure consists of several stages, which include preliminary steps such as rooting the smartphone and creating backup copies. You need to keep in mind that the terms “installation”, “installation” and “firmware” are interchangeable (they can mean the same thing). Some of the steps listed below may not be necessary for experienced users who have a good understanding of smartphone software.
Official ROM updates from device manufacturers are released in the form of convenient installation files that you can run on your computer after connecting your Android device. But firmware from third-party developers usually looks like compressed ZIP archives, rather than EXE installers or APK files.
Before you start flashing the firmware, you need to make sure that the device's battery is fully charged. Under no circumstances should you proceed with the operation if the charge level is less than 50%. Failure to take this warning seriously may result in irreversible consequences.
There are known cases when a smartphone's battery ran out of charge during the firmware process, resulting in the device being locked and unusable.
The next step only applies to devices equipped with the stock Android operating system. We are talking about devices such as Nexus One and Nexus S. If you are using other smartphone models, you can skip this step. The owner of a stock system must unlock his bootloader before starting the firmware process. This process will be the same for all Nexus models. After activating the bootloader, you can proceed to the next step.
Now you need to access the Root of your mobile device. If your smartphone has already been rooted, you can skip this step. Before installing the firmware, you must make sure that you have access rights to Root. Rooting is a mode of access to the gadget's system settings, necessary to perform complex tasks such as installing ROM. The process of gaining access to Root usually does not vary much between different device models. After successful routing, you can proceed to the next stage.
Installing the recovery function
To flash the firmware, the phone must have a recovery function installed (for example, Android System Recovery 3e). Rooting provides the user with the necessary level of access to perform administrative tasks on their device. Recovery offers the tools needed to actually perform these tasks. Every Android smartphone comes with a built-in recovery feature, but its functionality is usually very limited, so you will need a third-party Recovery to perform additional operations.
The installation process for this feature is usually not very different on different device models. After installing the recovery, you can proceed to the next step.
Now that the recovery feature is installed, you can perform additional operations, including flashing the firmware or installing an application from a ZIP file. The procedure is not much different for most ROMs, although some firmware require a special approach. Since the process may vary for some ROMs, it is recommended to search through a search engine specifically for your firmware.
Installing new firmware
There are 2 ways to install ROM. You can use ROM Manager to determine the steps you need to perform through Recovery, or manually reboot your phone into Recovery mode to complete these steps yourself. The first method seems preferable. If you previously used the rom manager to restore ClockworkMod synchronization, then it is already installed. If you don't have this app on your device, you can download it for free from the Android Market.
You need to follow these steps:
- Find and download from the Internet the ROM you want to install. This must be an archive with a ZIP extension.
- Connect the gadget to the computer via USB and install a memory card on it
- Copy the downloaded ROM to the memory card. It is recommended to place the firmware in the root directory of the removable drive.
- Launch ROM Manager on your phone.
- Click “Install ROM from memory card”.
- Scroll down the screen and click on the ZIP archive containing the ROM. The Installation Queue dialog box appears.
- If you want to install another ZIP file immediately after the ROM, you need to click “Add ZIP”. Then select the next archive that needs to be flashed. You can skip this step if you plan to install only the ROM.
- Click "OK". A Pre-install ROM dialog box will appear with options to backup existing firmware, clear data, and clear cache.
- Be sure to select the “Backup installed ROM” option if you do not want to lose all the files stored on your smartphone.
- You must use the "Erase data and cache" option if the ROM that is being flashed is an updated version of the software environment currently in use. Usually the program will tell you whether it is possible to install a new version over the previous one without deleting data.
- Answer “OK” several times to different questions. Now the device will reboot and the selected ROM will be installed automatically. The new firmware will be downloaded after the process is completed. You may be prompted to confirm the reboot.
If everything was done correctly, then the device should work in normal mode, but with new firmware.
The Android operating system is very stable, but in some cases problems may arise with it. They are usually associated with the operation of the current firmware. There are many ways to flash the firmware; In this article we will look at how to flash Android via Recovery.
There are several main ways to enter this mode:
How to get ROOT rights: Video
Firmware with ROOT access
Let's look at how to install firmware through it. First of all, you need to find and download the new firmware version as an archive.
The gadget will reboot and 8 items will appear in front of the user. Each of them is responsible for a specific operation. For example, if you go to “Wipe / Factory reset”, the system will be reset to factory settings (in some cases, by simply activating this item, you can avoid the need to change the firmware when the device begins to work incorrectly). “Install” makes it possible to install files when this cannot be done from the shell itself.
To install the firmware, you need to go to the “Install” section (it is located in the extreme left corner), select the place where the firmware was downloaded, and start the process.
After some time, the system will report a successful completion, then you will need to exit the “Install” mode and select the “Reboot” mode. There, click on the “System” item: if the entire operation was carried out correctly, the device will boot successfully.
Flashing Recovery mode
Now let's look at the question of how to flash Recovery on Android. To do this you will need to install the so-called CWM Recovery. The easiest way to do this is using a special utility, which can be found in the same Google Play store at this link. In this case, you will also need superuser rights. Having launched the program, you just need to follow its instructions by clicking “Next”. If CWM Recovery is already installed on the system, then the utility will simply ask you to select the appropriate item that performs an action related to flashing or resetting to factory settings.
When it comes to Android modding, root is an indispensable tool, but today the only thing a user really needs is a custom ROM. Not only does it allow you to back up your entire phone, install flash files and load custom ROMs, but it also speeds up the updated device. The only program that can handle this is CWM Recovery, which supports hundreds of phone and tablet models. The only hurdle when it comes to using CWM is to install the program correctly and keep your phone running.
Android is generally a great program, but sometimes the version a user gets with their phone doesn't always meet their requirements. CWM helps you install a new version of Android (or ROM) for better functionality. ClockworkMod is a popular custom solution available for the Android system. This tool is available on Google Play (official version of the app only) and is suitable for almost all Android devices.
Moreover, CWM Recovery runs smoothly on the phone and provides more features than the manufacturer. You just need to follow certain precautions before installing it:
- Make sure that the model is included in the official list of CWM recovery support.
- Charge the device fully to avoid interruption.
- Use original accessories to connect the phone.
- Download and install the appropriate USB drivers.
- Make a copy of the current profile.
- Unlock your phone's bootloader.
- Install CWM Recovery on your phone.
- Remember that all responsibility for flashing falls on the user.
Despite the difficulties and limitations, users cannot deny themselves the pleasure of updating their phone themselves. Pros of installing CWM recovery:
- Provides advanced features.
- Shares custom Roms and ZIP files on your phone.
- Creates backups and restores them for the user when necessary.
- Has the ability to install super SU (ROOT).
- Ability to customize and modify Android device.
Before you start installing CWM recovery, you should be aware of possible problems installing flashing. Negative consequences that your phone may experience after installing CWM Recovery:
- The phone may be completely damaged.
- The warranty will be void.
- There may be a problem with poor performance.
- There is a high chance of getting a broken phone.
- Increased vulnerability to viruses.
You need to understand that a smartphone is a target for viruses, malware, adware, all types of crapware, just like a PC. Before installing CWM Recovery, when the phone is flashed, the user can also use the flash drive of the device using custom programs. Making such changes to the software code increases the likelihood of virus infection. So these steps may harm your device while installing custom CWM recovery.
This is a process in which the user gains full access to previously limited features, settings, and performance levels of the device. In other words, the user gains access to the "root" of the operating system and can make fundamental changes.
Most users often do not need to reflash their phone. They are primarily driven by the thrill of getting the forbidden fruit, and not by the fact that they need the opportunities that will appear after the firmware. They will soon realize that this was not what they needed, although it will be too late.
Advantages of Rooting that you need to know before installing CWM Recovery:
- Launch special applications.
- More often than not, users boot up their phone to use an app that wouldn't run on "unmanaged" phones. For example, the Superuser application will allow you to control which applications can access the root system. After the phone is corrected, the user will be able to link the PC to the Android device.
- Allows you to connect to the Internet on your PC using your phone connection.
- Frees up memory on the “unmanaged” phone whenever CWM Recovery firmware is installed by storing it in the internal memory.
- You can move installed apps to an SD card and thus free up system memory for more app or file storage.
- Custom ROMs are available, perhaps the best feature of a rooted phone, which will allow for a wide variety of functions, including CPU acceleration and giving the phone a whole new look.
However, the user should think twice, if not three times, before he starts flashing his smartphone via CWM Recovery. The situation is justified, if he has a “brick” phone, then an unlocked phone can justify all the risks.
Saving the current state of the phone is a prerequisite before flashing the phone's firmware. This image will be recorded to the SD card and then copied back up to your computer. Some things to remember before flashing your phone via CWM Recovery:
- When you restore a full image backup, you can restore either all or nothing.
- Contacts should be backed up in advance to the Google cloud, so it's not worth backing them up separately.
- The user will need root to perform the backup as otherwise the phone will not give access to any application.
Since each phone has different settings, the easiest way to determine the correct one for your Android model and version is to simply Google: YOUR-PHONE YOUR-ANDROID-VERSION root.
Nandroid is an application that can take pictures of the entire smartphone and also restore them from instant photos. You can install functions via CWM Recovery only on rooted phones. The creation will take about 5-10 minutes, the process will create a new temporary directory on the SD card, which can be saved as a phone recovery disk.
First of all, you need to download the CWM recovery image for the desired phone model and rename it as CWM.img. And you also need to download the corresponding USB drivers for the phone and install them on the PC. Next, configure ADB and Fastboot on your PC. To do this, download and unzip the ADB files.
Installation procedure:
- Launch ADB with administrator rights.
- Click "Yes" to install ADB and Fastboot.
- Click “Yes” to install the ADB system as a whole or “No” only for the current user.
- Click “Yes” and continue installing the driver.
- Open the image CWM.img.
- Open a command prompt in the folder itself. To do this, Shift+click on any empty space, and then select the open command window.
- Connect your phone to your PC.
- Start in Fastboot mode and enter the code: adb reboot bootloader. After that, enter: flashboot flash recovery twrp-2.8.xx-xxx.img.
- Replace CWM.img above with the name of the CWM recovery image file. The phone will start blinking when installing CWM Recovery, after which fastboot will be performed. This command will reboot the device.
- That's it, Recovery installation is completed successfully.
- In CWM, manually turn off the device by holding Power. When it turns off, you need to press the exact combination of buttons. For most, this is the Volume Down + Power key. You can find the correct button combination on Google by asking a query such as “how to boot your phone to recovery.”
Installation 6 Recovery
ClockworkMod Recovery 6 was released for Galaxy Nexus and is one of the most popular custom solutions for Android phones. You can download CWM Recovery 6.0 using the ROM Manager application or launch it manually.
Full step-by-step instructions:
- Install all drivers for Galaxy Nexus to connect it to your computer.

- Once completed, select “Recovery” from the “Fast Boot” menu and enter “Recovery Mode.”
That's all. Galaxy Nexus will now show a new image.
It copes well with the task of flashing firmware for Android phones. First of all, you need to download the compressed program file to your computer as follows:
- Unpack CWM Recovery zip. Copy the compressed SuperSU-v1.65.zip file to the SD card of your mobile phone.
- Install the USB driver from this rar file before moving on to the next step. It is assumed that USB debugging mode is enabled on the mobile device. You can get it by going to Menu > Settings > Applications > Development > USB Debugging (check - ON).
- Select "Allow USB Debugging" - OK.
- Next, you need to disconnect your mobile phone from your PC and open SP Flash Too.

Samsung recovery
The step-by-step installation guide for CWM touch 6.0.3.2 is not difficult to follow. You will need the latest version of Odin_v3.07.zip on your PC and then install the application after extracting it. Next, download Samsung CWM Recovery. img to your computer and convert the *.img file to a *.tar.md5 file.
After converting the above downloaded file, you need to prepare your Samsung Galaxy S4 i9500 to enter boot mode. Turn off the phone, and then press Volume Down and Power at the same time. Launch Odin on PC and then connect Samsung to it via USB. After successful connection, wait for a while and then find the ID, the COM with its ID will be yellow. In the Odin settings, select the Reset and AutoReboot options. By clicking on the PDA select the downloaded one and then convert the CWM Touch Recovery 6.0.3.2 Samsung Galaxy S4 i9500.tar file. Click “Start” to initialize the installation, when the process is completed, the text PASS will appear in green. Select "Reboot system now".
Downloading the correct ROM for your Android phone is the easiest and most important step before starting the flashing process. There are many sources online to download ROMs. Before proceeding with MediaTek (MTK) recovery, you first need to install the drive. MediaTek devices usually come as a complete package that includes a pre-installer. Preloader - used for flash drives. Fortunately, in the case of a MediaTek or MTK device, there is a way to solve the problem using META Mode.
Before installing CWM Recovery on Android in META mode you need to:
- Open your computer's device manager.
- Remove the battery and connect the phone to the PC via USB while pressing the Volume Down button and wait 5 seconds to enter META mode.
- You need to detect the changes in the device manager, and when you click on the ports, a new device will appear, added to the port as a MediaTek USB.
- Fix preloader to change source ROM and flash drive using SP-flash tool.
- Open the SP flash tool, and load the unload file from the ROM folder. Uncheck all files except Preloader.
- Press the boot button on the SP flash tool and connect the USB to the phone without battery while holding the volume down button. Once the connection starts blinking, the process starts automatically. When the red progress bar ends, the Purple readiness indicator appears.
- When the process completes, the “Load” flashes.
- After the preloader flashes successfully, the phone will detect the MediaTek DA USB VCOM port in Device Manager.
- Disconnect your phone from your PC. After fixing the preloader, you can now easily launch the drive in your phone using the SP flash tool.
- Open the SP flash tool, and load the unload file from the Stock ROM.
- Press the download button and connect the phone via USB to the PC without battery while holding the volume down button.
- The user will see that the ROM is flashed in the phone without any problems. The process will be completed when the yellow indicator is 100% complete.
- Turn off the phone, insert the battery into it and boot it up as usual by pressing the power button. If there is enough battery charge, the phone will work.
Obtaining and installing a custom recovery is the first step towards customizing your device, and the above instructions will help thousands of users to enjoy a stable and unmatched performance of their smartphone.
We looked at several ways to install CWM Recovery on a smartphone tablet. There is no universal method; each program works with certain types of devices. Carefully study the documentation before installing the firmware, use the experience of others and success is inevitable. If there is no CWM Recovery for your device, do not try to flash an image from a similar one. It's better to be without Recovery than with a dead device.
In the last article I talked about. Today we will continue this topic and talk in detail about custom recovery modes, their advantages over stock ones and how to install them.
What is custom Recovery
Custom recovery is essentially an extended version of the recovery mode in smartphones and tablets. Its main advantage over the stock one is the presence of features that manufacturers usually hide from users in order to protect their devices from “those who like to experiment.”
With custom recovery you can:
- Make backup copies of various sections of the device’s memory or the entire firmware and restore them accordingly (Backup and Restore items)
- Install unofficial firmware (Custom Rom)
- Install unofficial add-ons and patches via the “install zip from sdcard” item
- Format various memory partitions (Among them are such partitions as: boot - boot partition, system - system partition, data - user data, cache - application cache, sdcard - memory card)
- Create new partitions on the memory card
The most common versions of custom recoveries are CWM (developed by ClockworkMod) and TWRP (developed by TeamWin). Both of these consoles have almost equal functionality and the choice of one or another recovery is usually determined by which one is easier to install or by the banal absence or presence of device support.
How to install CWM Recovery
Installation via RomManager
The easiest way to install CWM is to use the RomManager application. This application can be installed for free from Google Play, and from there you can flash CWM by selecting “Flash ClockworkMod Recovery” in the main window. From there you can reboot the device into recovery mode by selecting “Reboot into Recovery”. Please note that RomManager requires Root to operate. You can read how to get it.
Attention! Before installing recovery via RomMnager, be sure to check if your device model is in the list of supported ones here https://clockworkmod.com/rommanager. With rash actions you can turn your device into a “brick”!
Installation via Fastboot mode
The “classic” way to install recovery is to flash the recovery.img file directly into the Recovery section of your device via FastBoot mode. This method, unfortunately, cannot claim to be universal, because It requires an unlocked bootloader. But, firstly, it is not possible to unlock it on all devices, and secondly, not all devices have a Recovery section.
However, if your device meets all the necessary requirements, you can safely use the following instructions.
How to install TWRP Recovery
Installation via TWRP Manager
The easiest way to install TWRP, similar to CWM, is to install it using the special TWRP Manager application. Here you will also need Root rights.
Installation via ADB
Similar to FastBoot, TWRP can be installed via ADB
- Download and install the Android SDK, including Android SDK Tools, Android SDK Platform tools, and Google USB Driver
- Download the Recovery.img file from the TeamWin website (http://teamw.in/twrp_view_all_devices) by selecting your device from the list.
- Rename it twrp.img and copy it to the root of your device's SD card
- Connect your device to your computer via USB
- Launch the Windows Command Prompt by typing “cmd” in the “Run” box of the Start menu.
- In the window that opens, enter “cd C:\android-sdk-windows\platform-tools\adb”
- Enter the following lines:
su
dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p34 - Reboot your device
Also, TWRP can be installed via FasBoot, in exactly the same way as I described for CWM.
What to do if your device is not on the supported list
Most often, in the absence of official developer support, volunteers assemble their own versions of CWM. The methods for installing them can vary greatly; it can be installation from an SD card, firmware via Flashtool or Odin (in the case of Samsung devices). On devices with a locked bootloader, installation can also be performed through third-party applications.
