- Chainfire’s page states that the CF-Auto-Root tool found in this guide is based on Android 4.0.4 Ice Cream Sandwich and the IMM76D.P5113UEBLH3 firmware build number. That doesn’t mean you need to be running that same firmware build number, but you should use it as an indicator. You will find that some Samsung devices won’t boot older image files.
- You must have a Windows PC to use this guide otherwise the flashing tool will not work. You can use any PC running Windows XP and up.
