I unlocked my BL and flashed a rom last night as stock 4.2 was so laggy for me. I need to be able to use the barclays bank app.
so far i tried the methods on this post: http://forum.xda-developers.com/show....php?t=1823649
with no joy so i removed root via SuperSU app. I checked xbin and bin and SU file was gone.
I still get the RP029 error. Also have the 99999 error. If all fails is there a pure stock rom that i can flash without wipe? im on a 4.2.1 rom
