ClockworkMod is sewn into internal memory devices in place of the factory mode. In some cases, work is carried out on the gadget itself with access to Root rights, and in others - on a PC.

The article discusses such basic methods as Rom Manager, FastBoot, Rashr and Odin. For many devices, companies themselves produce separate utilities, for example, Acer Recovery Installer for Acer devices. CWM is implemented into the device memory on these devices also through ADB software, which is suitable for devices manufactured by HTC.

Rom Manager: Rooting and embedding

FastBoot Mode: Complex Method

Installation method CWM with using FastBoot will require skill from the user, since it is much more complex than the previous one. It runs not on the device, but on the computer. It is recommended to use it only if you already have skills in such operations. Before installation, you must download it to your computer or laptop. certain files. This list also includes the platform Android SDK, available for Windows, Mac and Linux.

Preparatory stage

What you need to have before installing CWM using FastBoot mode:

A computer with Windows OS and a USB cable to connect the device to the PC.

USB drivers for correct device detection. They can be downloaded from the official website of the manufacturer.

Android SDK platform.

Recovery file.

The Android SDK utility will help you install required packages Android SDK Tools and Android SDK Platform tools:

Go to the bottom official page. There will be three options. IN in this case This is the Windows version. Click on tools_version-windows.zip.

Download the Anroid SDK zip archive for Windows from the official website

Extract all contents from the archive to drive C. Open and click on tools. The android file that is needed for direct download packages is located there. Double click on the file and the manager is open.

Accept the license agreement

After the installation process is complete, find platform-tools in tools_version-windows. it will contain important files fastboot and adb.

The fastboot and adb files are located in the tools_version-windows folder after installing the Android SDK Platform-tools package

What else needs to be done before starting the firmware itself? Judging by the list above, you need the recovery-clockwork.img file. This is one of the key tools for further work. Downloading it won't be difficult, but it doesn't end there. It is important to place this file in the platform-tools folder. For further convenience in the firmware, you need to rename it to recovery.img.

Place the file in the platform-tools folder

Get straight to the point!

Now everything is ready for the CWM firmware itself, so you can safely get to work. Given below detailed description action in which it is quite difficult to get lost.

First, connect the device to be flashed to your computer via USB. Runs simultaneously FastBoot mode(combination of power and volume down keys). Although this combination works most often, it is not suitable for everyone. In some cases this Home key and the same reduction in sound. When the first option doesn't work out, nothing will happen if you use the second.

Start your device in FastBoot mode

The main procedure is performed on the command line. First you need to open it. In the Windows terminal window (press Win + R keys) write cmd command.

To open command line, go to Start and enter cmd

The command line is immediately ready to use. Type cd / immediately after the last entry and press Enter.

Type cd / and press Enter

Next, you need to go to the platform-tools folder in the terminal itself. The path to the folder may differ among users, so it is extremely important to use your own option so that the operation ends with famous success. Copying the path from the window line would be the correct solution.

The next line in the black window should look like cd path_to_folder_platform-tools. Press Enter again.

The next step is the adb devices command. It will help determine whether the PC sees the device. Next type adb reboot bootloader. Wait until the device turns on as a bootloader. Finally, go to the final part of the firmware: enter fastboot flash recovery recovery.img. and press Enter.

The adb devices command will help determine whether the PC sees the device

If successful, a message will appear. Check the installation the next time you restart the phone in recovery mode new firmware. If all is well, the device will enter ClockworkMod Recovery mode.

The level of complexity, as you can see, is high, so before the procedure it is strongly recommended to check that this method is suitable for the device, since it may not work in all gadgets. In practice, this method is good if the manufacturer of the device is HTC.

Rashr app

The installation method using Rashr is convenient and easy to perform; it is recommended for beginners. However, ironically, it also requires administrator rights. You can get them in a few steps. detailed instructions was given earlier in the section on Rom Manager.

Odin: solution for Samsung

The previous three methods are suitable for different models devices. The same method is effective for Samsung devices. This is a proprietary utility, so it cannot be used for devices from other manufacturers. There are many versions of this application. The latest one is Odin 3.09.

Here the standard factory version of Recovery is changed to a modified one using a PC, as with FastBoot:

Download Samsung Odin on the official site.

Download the Odin program on PC

Establish a connection between the PC and the gadget via a USB cable and switch the device to Download Mode. There are two options depending on the device model. If one doesn't work, another will definitely work:

power/lock button, Home and volume down (all other devices).

Pressing the volume up button confirms entering recovery mode. Next, launch the already downloaded Odin program. A program window will open, where I will list available files for download.

using the ROM Manager program by selecting home page"Download" section Recovery mode»;

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;

by using ADB programs via 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 smaller volume memory problem disappears. The reason lies in the Windows system. The fact is that it diverges from card formatting standards. To ensure formatting is performed 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 connected 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 more available options, select them.

Install universal drivers.

Find a more suitable one Recovery program for the device.

Recovery menu doesn't work

If at startup alternative mode recovery (volume + Home button or power) a picture appears with a lying robot, then the recovery was flashed, but when the device was restarted 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 and hold them 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 stock recovery custom and the “No command” error will be fixed.

Flash new mode Recovery means getting new ones 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. Suitable for HTC more way with FastBoot, and for Samsung is more correct will select Odin.
