Well, I went to the Sprint Store and the lady put a new battery in it. She said that the phone booted fine for her, but that the charging port was bad. But whenever I plug in the phone, the orange charging light comes on. Also, I can't get it to turn on at all now. Not even any rebooting. I don't know what's wrong, but my warranty ends tomorrow, so I'm just going to send it in to get it fixed. Thanks for your help guys.

EDIT: Weird, as soon as I posted this, it booted up. :/ Still not sure if it's charging though. Anyway, this thread is pretty much solved now. Just wanted to post this to let people in the future know.

Answer: Get a new, charged battery. That should work. Good luck guys.
