My phone just hard resetted itself.
Woke up this morning, found that it was behaving somewhat erratically, like apps wouldn't launch properly -- some nonsense about not being trusted or signed, and a few other anomalies, then I decided to power it off then power it on, and it was at this point that I was greeted with the provisioning screen.
2 hours of customizations lost!
(Note I've been on previous MR's since the TP2 was released and had no problems).
Looks like I will flash to the Sprint 6.5 Stock for now.
Thanks anyways MM.
