Hi! I followed your instructions to the tee and (I think) it works 100% ( 'coz i never encountered any errors ) my question is, how do i check if i really made the back-up...?
note: i'm not using any sd/external card.. so i'm assuming that the backup will go to my phone storage.. am i correct? thanks!
