TRYING to unlock the SPC on a sprint touch pro so i can flash to cricket

[boredmug]

Ok.. i'm a noob to this but i'm trying to get a friends Touch Pro to work on Cricket and really am having a hard time going about it. He hasn't activated it to Cricket yet, but i understand i need to Zero out his SPC? I used BAFTools and got his unlock code which allows me to change stuff under PST(EPST). I've tried using Qualcomms QPST to zero out his SPC but it never finds the phone when i'm adding com ports. Windows 7 fails to find one driver, maybe that has something to do with it? I'm really lost at this point. I think i'm kinda working backwards.. Previously i've unlocked the phone, flashed a cricket specific rom and flashed a cricket prl. I know i should update the prl with *228 but can't until the phone is activated. SOMEONE HELP PLEASE? lol. I think i'm on the right track, but i'm stuck on zeroing out the SPC. I'm assuming this is absolutely necessary?
