So i have used rsd lite a few times for rooting but never to unroot a phone, and have seen enough posts on here to make me uncomfortable using rsd to unroot because most of the problems with rsd come from unrooting as far as i can tell. I know there is another method which is to use the stock nandroid backup i made but im not sure if that is the best method of doing it. Basically my questions are should i use rsd to unroot, which sbf should i use or does it matter (the current build on the phone is frg22) i just need to know if i can flash frg83 or if i should use a earlier build, also what version of rsd lite runs the best i saw a couple posts saying 4.8 was giving some trouble. Any help is greatly appreciated. Im freaking out about it becuase i hate using rsd i would prefer avoiding it if at all possible!
