Hey guys I have a question. Im new to the newer basebands on the S4 so Im a little confused with all the safestrap stuff (you can thank my phone for having MDK that im so out of date lol). I bought my girlfriend a S4 off Swappa and it has MK2. Did all my XDA and googling and I have all my files and such for root and safestrap but here is my question. Once I get safestrap installed on her phone, is it necessary to do a backup of the Stock Base Rom? I dont see a point since it should not be touched in the 1st place and only use ROM slots for loading but Im not sure so I want to ask all you experts on this. Thanks guys
