First of all , let’s talk little about recovery…you should know that.
Have you ever observed your phones storage? If it’s 64 GB storage, usable memory you get isn’t that much. Its usually about 52,55 GB. Where does the other space go?
Its used by Android system by itself . The whole compiled code of android system installed in your phone is kept there. It isn’t kept directly as is into it but there are some partitions made and specific code is placed in specific partition.
One of those partitions is recovery partitions. Its usually responsible for flashing your phone, resetting it, erasing other partitions etc a piece of code which wakes up recovery partition during phones restart and helps to perform all operations/responsibilities of recovery partitions is called “recovery”.
TWRP(Team Win Recovery Project) and CWM(Clock Work Mod) are both examples of those piece of code..
So as you know little about recoveries, let’s now go ahead and see how do you backup and restore using TWRP and CWM.
Note: installing TWRP/CWM requires that your phones bootloader is unlocked. Follow article “How to unlock bootloader of your mobile device” for unlocking it.
How to back up android partitions using TWRP/CWM:
- As every device model as different hardware, their partitions structure is also different. Thus, recoveries for every phone model are unique. Download one specific for your phone model. Search for “TWRP for <device model name>” or “CWM for <device model name>” and download the recovery.
- Download ADB-FASTBOOT drivers from here. Install them on your PC.
- Go to Settings –> Developer options on your android. If you don’t see developer options then go to About phone and click on Build number 7 times. Come back to settings, you should have it now.
- Turn on “Android debugging” or “USB debugging” option.
- Connect your phone to PC and execute commands below:
adb reboot bootloader
- On successful execution, your phone should automatically go off and start again into bootloader mode. You are ready now to execute next command.
fastboot flash recovery <path to downloaded recovery>
- Now here you might encounter error saying that fastboot is not recognized. In that case, Download ADB-FASTBOOT from here, extract it, go into the extracted folder, keep shift pressed and right click. Select “Open command window here” and execute above command into it. It should work now.
- There might be another error where the command prompt keeps waiting for device saying <waiting for device> message. But this is something specific to device. So let me know in case you have such error.
- On successful execution of above command, execute below command.
adb reboot recovery
- Your phone should boot into recovery that you just installed. either TWRP or CWM.
- Awesome. Now check out snaps above and refer them for procedure of backing up android partitions.
- If you are on TWRP, directly select back up option, select partitions to back up on next screen and swipe the slider at bottom to start backing up. This procedure creates TWRP/backup folder in root directory of your device internal storage.
- If you are on CWM or Philz recovery, select “back up and restore” option, select partitions. It should start backing up partitions. This procedure creates CWM/backup folder in the root directory of your device internal storage.
- That’s it, you did it !!!
