Big Problem W/ Diamond

[wtr1906]

My friend put a ROM on my phone and it was working fine. I re-downloaded Windows Live and now my phone just sits on the home screen and says "Tap here to Launch TouchFLO" . So I just wanted to do a hard reset but when I try to hard reset phone this is the error I get;

Power + Vol Down + Reset using stylus tip
Bootloader says :

Security Unlocked
DIAM500
SPL-0.57.0000
MicroP-Diam (LED) vB
PSOC-Diam STAGE_EVT v20

Im not sure how to fix the problem and my phone will not come back into service. Any help would be greatly appreciated!
