Is it possible to revert from Jelly Bean to ICS 4.0.4 without root? Thanks. Edit: Yes, it is possible! Thanks to forum member kbbru who collected the steps needed (you can thank him in this post). Also a huge thank you to the guys at www.sammobile.com, xda-developers.com and www.androidauthority.com for all the great info available. Please remember the below method is for the P3110 model (methods for other models may vary) and everything you do is at your own risk!
