I had in the past had to run factory reset which cleared out all my data and applications so I could update to 4.2.1 and earlier versions
This is a painful process to redo Amazon...Playbook..re-registration .etc....
If I were to backup (nandroid backup) , do the factory reset, update the firmware to 4.2.2 (whenever it comes out). Can i use my nandroid back up to bring back my data and applications
In anticipating the new firmware's arrival, is it possible that we can have a step by step instructions how to update firmware for rooted N7
