Great Success! I flashed the sprint OS ROM rather than the radio and it seemed to reset everything. I'm not running Juicy's latest ROM without any problems.
What I did:
1 - Flashed the sprint stock ROM from

2 - Pulled battery at screen calibration. Hard reset again from shutdown (power+vol down+center button).
3 - Flashed winmo6.5 ROM (Juicy 7)
4 - Clear storage (under system settings)
In my case I did not lose activation. Hopefully this is helpful. Good luck.
