The Root

  1. Let’s start by taking advantage of the Custom Recovery that we just installed by performing a complete backup. To do this, restart in Recovery mode (top volume + home + power button). From the menu, move using the volume buttons and select backup and restore, then backup. Then select reboot now
  2. Place the CWM-SuperSU-v0.96.zip file on the root of the phone
  3. Restart in recovery mode (as in step 1) and select install zip from SD card
  4. Navigate to the CWM-SuperSU file -v0.96.zip and confirm
  5. Once the file is installed, return to the main menu and select reboot now

On some devices, CWM does not seem to be

If you cannot access Custom Recovery, the basic Android recovery mode will reinstall at startup and overwrite Custom Recovery. Then follow this method:

  1. Perform the procedure to install the CWM, but at the end, when the Samsung logo appears when you restart the S3 4G, wait 2 seconds and turn it off immediately. The image following the Samsung logo should not have time to display
  2. Then proceed to root.
  3. Then install a file explorer (File Explorer, File Explorer, etc …) with root privileges, and look for a file named boot-recovery.p, or recover-from-boot that is in the folder / System. Rename it by adding .bak at the end. (Example: boot-recovery.p.bak).
