So I rooted my galaxy s4 AT&T and I rooted it while on mf3. Is there a way for me to upgrade without breaking my phone? I don't care about keeping root. Just need to update! Thanks!
Post 2 has everything you need to root your devce and install a new Rom.

If you want to just update and not care about rerooting ever again, you can download the stock rom and install it via odin. It will unroot your phone in the process.

So can I use JODIN to flash straight to 4.2.2?
Sorry about all the questions...
