My son's nexus 7 needs fixing, I have to send it off and they will probably need to do a factory reset. I am owner and main user, he has a user account that I have to allow apps to be usable from my account. I have found Helium, which backs up from my user fine, but he has loads of game hours logged up on his favorite games and I can't seem to find a way to back up his progress. I am not someone brave enough to read about and try "rooting" etc just want a simple way to back his stuff up without voiding my warranty. Thanks in advance
