Key Points to Note

  • The SlimBean Build 6 ROM and instructions provided in this guide are applicable for the Galaxy S2 GT-I9100G model only and will not work with any other device. Verify the device's model number by navigating to Settings > About Phone.
  • Backup important data and settings on the phone by using one of the recommended custom recovery tools such as ClockworkMod (CWM) or TWRP, as it creates the complete image of your phone's existing setup.
  • Ensure the device has at least 85% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
  • Verify correct USB drivers for the phone are installed on the computer (download Samsung Galaxy S2 GT-I9100 USB drivers)
  • Ensure USB debugging mode is enabled on the phone, by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or Settings >Applications> Development (if device is running Android 2.3 or earlier). Otherwise if device is running Android 4.2, perform the following steps:
  • Go to Settings > About Phone
  • Scroll to the bottom of the screen and select Build Number
  • Tap the phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings. Then select the checkbox to enable USB debugging mode under Settings > Developer Options.
  • Ensure the device is unlocked (not locked to a specific carrier) and rooted with ClockworkMod Recovery (CWM) installed.
  • If the device is stuck at booting or is 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 on it.
  • If you encounter a Status 7 error message while flashing the firmware, then it could be due to an incompatible device or a necessary kernel may be missing (for instance, a Jelly Bean Kernel must be installed before installing any Jelly Bean ROM).
  • The instructions given in this guide are meant for reference purpose only. IBTimes UK reminds its readers that it will not be held liable if the device is damaged or bricked during or after ROM installation. Users are advised to proceed at their own risk.

NOTE: Once the device enters CWM recovery, use Volume keys to navigate between options and Power key to select an option recovery.
