Fast forward to today. I just upgradd to the GS5 and want to sell my xt907. I would like to "unroot" it before selling, but am really not sure how or if it is possible. I do not have a stock rom, and am not sure what steps or software are involved so if anyone can explain to me it would be extremely appreciated. I can sell it as is, but it is not taking the new update available so that is a downside for selling.
