    Hi all, I installed the RUU update on my phone last week and have had some issues downloading apps I used to have on my phone. Is there anyway to downgrade back to the stock RUU? I need to get a couple of those apps back and do not want to wait for an OTA to finally be able to so.

    I did the same thing ... In that I flashed the leaked RUU and tried to flash back to the original that came on the phone... It won't complete it said main version is newer and won't downgrade I think u are gonna have to root and get "s-off" then flash back I am going to try that when I get the time/ feel like it ...

    The only solution is to temporary root the phone, then flash the stock rom. This is the only way to upload an older firmware.

    Lol. Yep, you're going to have to root it.
