Let’s say that fails. You get some USB error which is more common then most would like, you will have to try and flash the PB31IMG through Hboot. You will have to do this blindly as Hboot, like the rest of the device, won’t be visible. To do this download the file below and rename to PB31IMG.(Sd card must be formatted to Fat32). Then move the file to your SD card. Boot into hboot by powering up while holding the volume down button. Wait about 2-3 minutes and proceed volume+. Wait about another 5-10 minutes and press the volume+ one more time. Phone should show a display again and be back to life.
Once that is down you’ll be back to a semi-stock device but still will be s-off. This is not a bad thing. If you used the PB31IMG method delete it off your SD card. Download this version of ClockWork recovery and flash through Hboot.
I think what happened is the unroot zip I initially downloaded was for the AMOLED screen and I have a SLCD. It was not clearly marked one way or the other, so I'm pretty sure that's what I did. I'm just trying to get it fixed now. The reason I asked the question about the battery is usually my phone vibrates even when I boot into recovery, but it's not doing anything.
