Troubleshooting CWM Recovery Installation
  • Sometimes, certain Galaxy S3 I9305 devices reflash stock recovery automatically over the custom recovery you just installed, so you always end up with stock recovery even though you installed a custom one
  • To stop this from happening you have to turn off the device immediately after it reboots after you install CWM recovery. So as soon as you see the Samsung logo, wait 2 seconds and press the power button. This will stop the system from reflashing stock recovery.
  • Now enter Recovery Mode
  • Access your phone via 'adb shell'. In the shell type "mount /system" and then "rm /system/boot-recovery.p" or "mv boot-recovery.p boot-recovery.p.backup"
  • Reboot and you will still have CWM installed
