  • 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).
