Run z4root and tell it to unroot. One of the options on the screen when you run it. You will have to wait for GB. Its been pulled due to some problems with Exchange.
How would i sbf and whats the difference from doing an sbf and just unrooting with z4? I also have fission installed do i need to do anything else to get rid of fission and returning completely to stock?
im pretty sure that when i sbf'd for some reason it still had the superuser icon in my apps. so you may have to hit unroot with z4root after sbfing to be completely back to stock
