- Samsung Galaxy S3 I9305
- Odin (Download link)
- Unzip the ODIN files on your desktop after you download it
- Download I9305_CWM_Recovery.tar.md5
- Turn off Samsung Kies on your computer
- Enter Download Mode (Power off and then press and hold the power + volume down + home buttons at the same time)
- Connect the Galaxy S3 to the PC with the USB cable
- Run ODIN
- Wait for your phone to be recognized in Odin. Look for the yellow square in the left side up
- Click on PDA and add I9305_CWM_Recovery.tar.md5
- Press Start
- Wait for the phone to reboot
- After installing CWM using the steps above download CWM-SuperSU-v0.98.zip and place it on your sd card
- Turn off the device
- Enter Recovery Mode (Press Home + Power + Volume up simultaneously)
- Choose 'Install zip from sd card' and choose the CWM-SuperSU-v0.98 file
- When the flashing is done you will have root access on your Galaxy S3 I9305
- 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
