Key Points to Note

  • The SlimBean Build 5.7 ROM and the instructions given in this guide are meant for the Galaxy S2 GT-I9100 only. Verify device model number by navigating to Settings > About Phone.
  • Back up important data and settings via a recommended custom recovery tool like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup
  • Ensure USB debugging mode is enabled on the phone, by navigating to Settings > Developer Options (if device runs Android 4.0 or later) or Settings > Applications > Development (if device runs Android 2.3 or earlier). If device runs Android 4.2, perform the following steps:
    • Go to Settings > About Phone
    • Scroll to bottom of screen and select Build Number
    • Tap phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings. Then select checkbox to enable USB debugging mode under Settings > Developer Options
  • Make sure phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing ROM
  • Ensure device is unlocked (not locked to a specific carrier) and rooted with CWM Recovery
  • If device is stuck at booting or experiencing boot loop issues, perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting
  • Allow newly installed ROM to stabilise for five minutes before you start working
  • If "Status 7" error pops-up on screen, it means you could be flashing the wrong device or a related kernel might be missing (for instance, a Jelly Bean kernel should be installed before flashing any Jelly Bean ROM)
  • Instructions provided in this guide are meant for reference purpose only. IBTimes UK will not be held liable if device is damaged or bricked during or after firmware installation. Users are advised to proceed at their own risk.
