How to extract files from a Nandroid Backup?
Note: The below tutorial has been tested only with Clockworkmod 22.214.171.124 Touch’ s Nandroid Backup
When you take a backup from CWM Recovery, the backup is stored in the below location on your phone,
SD card/clockworkmod/backup/(Date & Time of the backup)/**All the backup files**
Copy the backup folder in your computer. When you browse the files inside the folder, you can find that it has TAR files. Exclude the files with 0 byte size’s. The below two are the only files needed.
- system.ext4.tar.a – Contains the system files
- data.ext4.tar.a – Contains all other data files
Before doing anything always make sure you take a Backup of the Nandroid backup..
Install 7-zip, an open source file archiver to open the TAR files. (To know more about 7-zip, please check this article 7 zip)
Rename system.ext4.tar.a to system.ext4.tar and data.ext4.tar.a to data.ext4.tar
You will now get a confirmation message, go ahead and click Yes. Since there is already a blank file on the same name, just replace it or rename it to another name.
Now, you can right-click the file and go to 7-Zip –> Open Archive or Extract files
Now, you can extract the required files from the Nandroid backup.
