Stock ROM did not fix it. (I edited it into the first post the day I posted)

Taking the battery out, for any amount of time, after powering down does not fix it either. No matter how long I wait, as soon as I put the battery back in the phone powers itself on.

Looks like I'll have to be calling Sprint to get a new phone.. again.
I just recently received this one about a day or three ago as a replacement for a cracked screen I managed on my old one. Looks like they sent me a bad one.. so it shouldn't be much trouble getting them to send me one that actually works how it should.
