Thanks for the tips everyone!

I've tried them all, but unfortunately it still seems to be in a boot loop.

I guess I'll have to buy a new one. Mainly bugs me to have to wait a couple of weeks to keep working on this.

I tried powering it directly from my lab power supply, and still had the issue, so I don't think it's a power issue.

My prototyping power supply decided that it was time for the lm1117-3v3 to smoke and pass 9v to the part.

Grrr!

Have one more -01 to work with.
