I've had the Motorola Razr for a while now and when i first got the phone i rooted and uninstalled some bloatware through titanium backup but didn't think to make a full backup of the phone at the time! I read somewhere on this site before that all stock apps are needed to perform updates! i finally got the Jelly Bean update through this morning and tried to install it! it fails after downloading and about a quarter of the way installing the update! I fully un-rooted thinking that might have been the problem but it still it fails! Would it definitely be the fact that some of the stock apps aren't there and would a full factory reset re install them or would i have to learn all about Roms and stuff and flash a stock one to my phone to get the jelly bean update to work?
