I have a T-Mobile G2 on Android v2.3.4 which is a little out of date. Lately, it's become rather sluggish and since Jelly Bean is out, I'm wondering if it's possible to upgrade it manually through a process that takes less than 25 steps; I'm all about easy. Most critically, I don't want to screw up the device (brick it) and I'd like to be able to make a backup prior to the upgrade in case there are photos or anything that didn't get cloud synched.
Any ideas on the best/easiest way to do this?
