So I'm freaking out and am praying I didn't brick my phone. I downloaded the AOKP release for the i9300 (I have an ATT S3), I installed the download through Clockwork Mod. After wiping then installing the ROM, the phone has gone black. The phone does not respond to any button pushes at all and will not turn back on. I had the phone connected to a charge while installing the ROM and had about 20% battery life? Help, please?
