Ok, so last time this was updated I read on the xda thread that if I was on build 12 that I could just flash build 13 right on top and don't need to wipe data or anything , just flash this puppy right over.
So I did that and when the phone rebooted I didn't even have the option to sign into google, opening gmail it would immediately close out and force close.. blah blah blah... Basically what I had to do was factory reset and wipe eveything as usual and then flash build 13.
So my question is: Did something just go wrong last time ? OR Do I really need to factory reset and wipe cache and dalvik before flashing this build over build 13 that I'm running now?
I know this kind of stuff is asked all over and that it's probably said a million times on XDA but I can't seem to just get a definitive answer.
Thanks in advance and sorry for a noob question..
