ClockworkMod Recovery (CWM) is a replacement recovery option for Android devices, made by Koushik "Koush" Dutta. It is based on the Android 2.1 (Eclair) recovery image. Features include Nandroid backup, adb shell, advanced update.zip options (ignore asserts and signature checks), and file browser for choosing update.zips
The Rom Manager app may be used for installing CWM, overwriting the device's stock recovery. As with the stock recovery, CWM can apply software changes to the device. Unlike the stock recovery, CWM is able to entirely replace the device's primary Android operating system ("flashing a new ROM"), including with aftermarket replacements such as CyanogenMod. Once installed, CWM it is accessed by turning your phone off, then triggering the bootloader prompt by holding down some device-dependent button combination as it is turned on.
CWM is also known as clockwork and CW recovery.
Note that it's usually possible to find pre-built CWM images.
Rom Manager - Rom Manager is the original and official way to install ClockworkMod recovery by a .zip file. Download "Rom Manager" from Google Play, use the app to download the correct version of CWM for your phone (update.zip file), reboot into the stock recovery and choose the option "re-install package" TWO TIMES to temporarily load CWM from the update.zip file. This file needs to remain on the phone to load CWM when needed each time. DO NOT DELETE!
You can find and download the update.zip by yourself, place it on the phone in /sdcard/ and boot into recovery using the 3 button method, choose the option "re-install package" TWO TIMES to load into CWM. Once again the update.zip needs to remain on the phone. DO NOT DELETE!
(Some models) Flash/Use a kernel with Clockwork built in. Most cooked Roms for compatible devices include a kernel with CWM built in. With this method you DO NOT need the update.zip file or Rom Manager anymore. The update.zip may be handy to keep in-case you install a new kernel without CWM built-in, but it is not necessary.
For Samsung Galaxy S phones: From stock it is easiest to get CWM by flashing a kernel with CWM built-in by using Odin3 1.7 flashing utility. Only some kernels come in a Odin compatible package (.tar file).
- Install CWM Recovery to Samsung Galaxy tab 2 7.0 (GT-P3110) with Linux and Heimdall:
- install Heimdall (and optionally Heimdall-frontend) on your GNU/Linux host computer. This software is a flash tool which copies firmware images to device's specific memory area. Odin is its clone :). You can find several guides how to install this even from source. You don't need windows stuff such as odin or Kies or a fake software which contains the usb drivers because most probably the kerner drivers are preinstalled on your GNU/Linux OS.
- download CWM to your GNU/Linux computer: clockworkmod.com/rommanager (recovery-clockwork-touch-22.214.171.124-p3110.img) You can navigate in the menu with volume up/down keys and choose item with power button. If image name contains touch then allows navigation with touch too.
- turn off the tablet (wait around 10 secs while screen goes black)
- boot into recovery mode: keep the the volume key pressed which is closer to the power button and at the same time keep the power button pressed also. You may keep them pressed as long as you like: logo appears then device reboots. When logo appears release keys. Android system recovery <3e> default recovery loads. Choose "wipe data/factory reset" menu then "Yes -- delete all user data".
- be prepared to execute next step then choose reboot system now from menu
- after reboot don't allow system to load: immediatelly keep the power button pressed and the volume key which is on the far side. Keep it pressed until warning appears
- connect tablet to GNU/Linux host with USB cable then press the volume button which is close to the power button
- with root permission run command on GNU/Linux host and be prepared for executing next step immediately sudo heimdall flash --RECOVERY recovery-clockwork-touch-126.96.36.199-p3110.img
- when it completes it restarts the device: remove the cable and immediatelly boot into recovery mode: keep the volume key pressed which is next to the power button and also the power button: keep it pressed until logo is displayed on 2nd time then release them.
- ClockworkMod Recovery loads and you can use it. Scroll down to see all the menuitems. You can create backup with backup and restore menu then backup to external sdcard
- After all use last menuitem: +++Go Back+++ / reboot system now / ROM may flash stock recovery on boot. Fix? If you choose No then you can do the procedure again. If you choose Yes then Samsung's recovery firmware gets overwritten by ClockworkMod Recovery.
Tried this in Karbonn A21. 1. Connect the phone to PC using USB cable 2. Select to copy files to/from your computer" in the notification panel menu. 3. This will open up two drives within Windows Explorer 3a. One drive with the internal SDCARD of A21 3b. One drive with the additional SDCARD that you had inserted [optional] 4. Copy the recovery.img to the root of the SDCard (Select "USB Connected - Karbonn has a built-in SD card /sdcard/ but the additional SDCARD will become /ext-sdcard/ which cannot be used normally) 5. Open any terminal emulator in your phone. You can try this 6. Type following commands : su dd if=/dev/block/mmcblk0p16 of=/sdcard/mmcblk0p16.backup bs=4096 dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p16 bs=4096
Also tried this in Karbonn A21 1.
