  • Power off your device and then boot your device into the custom recovery mode. To do that, hold down the Home, Volume up and Power button altogether for a few seconds. After that, press the Volume Down button, and your device now is in custom recovery mode.
  • Now, tap on Wipe option, select ‘wipe data, cache, dalvik, system’ and swipe to confirm the selection
  • Then, load the firmware by selecting “Install zip from SD card” and “choose zip from SD card”.
  • Now flash the Rom you have put into your device and wait for the process to complete. Once done, you will be asked to reboot, tap on “No” to continue to flash the Gapps package
