I don't want custom kernel or temporary CWM. I need permanent.
And please, can you show me a good&safe tutorial for re-flashing STOCK rom 4.1.2 on Ace II? I'm really distrusful with all the tutorial here. For my old phone(galaxy fit) I had clear&safe rules to follow that never gave you a chance of bricking. 0% chance of bricking!!! For Ace II I cannot find something 100% safe, or am I blind ?
EDIT: Is this tutorial safe for re-flashing stock rom?: http://forum.xda-developers.com/show....php?t=2118119
