Will doing a hard rest bring me back to the original OS the phone came with? I am LOST in trying to get off the .904 leaked update. I am not tech savvy and probably should never have done the manual .904 leaked update. Since going to .904, my battery life sux! If a hard reset will not do it, I do need a detailed step by step on how to go back. I [wanted] to try the 7 or 8 step method listed in another thread here but was too intimdayed/lost. Pls help. Thanks.
