I have a note 10.2 which runs with android revolution hd 9.0. I am trying to update to android revolution hd 11.1 but the system stops after asking if I wish to back up the efs partition to external card. I have tried both ways, i.e. without backing up and with backing uo but to no avail: when I press the next button the system freezes and I have to reboot.. I have also tried to select the option to wipe the data but again with no result. The system freezes and restarts with version 9.0.
Any idea how to proceed?
