Hi after messing around with the online and offline versions of Jodin3 i have finally managed to flash the stock 4.1.2 S2 firmware to my phone..the issue i am having is that my reason for the flash was to unroot (because a banking app i need won't work with a rooted device). Should i have the "re-partition" box ticked before clicking start? i have had it unticked so far.. i don't know what that will do. There is also an "F.Reset" box but that remains untickable whatever i click.
Any suggestions would be much appreciated.
