I have an ATT S3 with AOKP version jb-mr2 mileston1
I read here: http://forum.xda-developers.com/show....php?t=2658486 that I could just run this recovery zip and everything would be good. I don't know this guy from adam. So that bothers me a little (he is highly rated, a contributor, etc...getting roms from strangers is just a paranoid thing with me...no offence.), but I'd be willing to do it if it is the only way.
I was looking for a way to do it via heimdal/odin by flashing the stock rom. This has the same trust issues I guess. I didn't find a definitive how to on this for my particular situation.
Ideally I'd like to go straight to the source and reflash everything. I read in this thread that I shouldn't use Kies on the stock OTA to go back to stock, but that's not what I'm doing. However, I would like to avoid bricking my phone.
