Connecting it to a PC and pushing both side buttons worked for me - seemed to snap the phone out of whatever loop it was in. The screen was totally dark but I kept hearing noises like it was trying to start. Once I did this, it rebooted, and it's nearly fully charged, so battery wasn't the issue. Anyway, thanks for the help!
