To keep this short and simple... If you have a pi that fails and you're not too close to an electronics store...
Check your local Target. The one next town over from where I live had them in stock. Allowing quick replacement and on time show for tonight.
Thought I would share this in case anyone else has a pi suddenly fail.
For those wondering, and maybe can help answer why? The power circuits would overheat immediately with power, causing a post boot loop. I don't know how long it was doing that as it was working when I went to bed last night. I'm referring to the chips/circuits right next to the power socket on the pi.
