You just got your replacement (refurbished) Touch Pro from Assurion (Sprint warranty people). You’re trying to unlock the thing because you can no longer take the sluggish stock ROM. Only problem is that when you try to run the unlocker, your phone gets stuck on the “Loading…” gray screen.
Take out your Removable MicroStorage card and try again. Worked like a charm for me. Sucks it’s such a simple problem.
(I found out that this was the problem by reading comment 370 here. Make sure you thank rawdikrik if he helped you out.)
