[NighthawkIX]

Steps in detail:

Unlocked using Hard_MFG_SPL 2.4
Loaded No2Chem's 5051
Didn't like the 5051's compatability issues with some of the apps
Loaded Sprint's 2.7 without relocking the SPL or converting back to basic.
SPL and ROM didn't match or something, got stuck in bootloader screen.

Fix:
Hold Power/Camera+Reset to get into tricolor
Flashed to 3.16 unofficial so the ROM's compatible with the SPL

---> Happy.
