*WARNING* PLEASE READ I do not take responsibility if you brick or damage your phone, even if it is highly unlikely. I also suggest a factory restore before attempting this. I did not wipe my phone and ended up having to anyways as it got stuck in a boot loop. To get into download mode hold Power+Home+Voldown on boot. If you get stuck in a boot loop, you can get to the boot manager by pressing Power+Home+VolUP.
