[HELP] Download mode will not work
So I am trying to get my phone back to stock so I can send it back to verizon because my power button is no longer functional and when I try to go into download mode it goes to the screen with the yellow triangle just fine, I hit up on the volume it goes to the next screen for about a second then the phone goes off. I'm pretty much at a loss here on what to do, I just need to get my phone back to stock to send back, I am currently on notta's PA build.
