Pre-Requisites

  • The SlimBean Build 8 Final ROM and the instructions given in this guide are meant for the Galaxy S2 GT-I9100 model only. Verify the device model number by navigating to Settings > About Phone.
  • Back up data and settings using a recommended custom recovery tool such as ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup.
  • 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.
  • Make sure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
  • 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).
