I rooted my Verison Galaxy S4 before they updated the bootloader to ME7. If I wanted to unroot my phone can I follow the ME7 unroot instructions to update to Android 4.3 bypassing the update, or do I have to go back to what my phone was originally prior to updating?
Re: Unrooting Question
Honestly, I would suggest holding off for a little bit. Here is why: I have seen many threads reporting bugs...well, more like complaining of problems after updating, and rightfully so, of various kinds on the 4.3 update. If yours is still 4.2, I would implore you to be patient for a little bit before doing anything.
These bugs aren't minor; contacts and TouchWiz crashes, Wifi not turning on, dialer problems...there is more, but that is all I can think of.
