The best and easiest way is to make a backup using cwm recovery before making any changes to the device and save that backup forever. Then, when you want to RTS, you flash that and Odin the stock recovery and yer done. Now you have to delete all the stuff you installed. Factory reset does not uninstall system apps, only data/apps.
Well usually I do make cwm recoveries, but this time i didn't. Now Im running the stock rom plus. I have made a recovery, but not of the original rom. Is there any way for someone to share their back up with me with out them giving me their personal data and what not?
Thanks for the reply!
You could get the stock system.img and flash it with Odin or terminal emulator
With the new update I want to return to factory stock. Anyone have any ideas, because I cant flash the system.tar through Odin.
For some reason kies does not recognize my phone. I get "lies does not support this devices". Any ideas as to why ?
