If the first process will take more time than usual or fails and doesn’t load the new home logo, or the device enters into a boot loop, repeat steps as given above. .

Note: If you don’t like the new custom ROM and the way it’s working you can restore your previous ROM by using the previously created Nandroid backup file. Use our comment section from below for other supplementary questions.
