Help with Activation

[timsmooth]

I just sold a ppc 6700 with helmi cs wm6 pro update, and now that person cant activate the phone. Is there a way I can go back to the stock rom for the 6700? Is there a way I can get the phone activated. Please help. She says sprint cant activate the phone. I am assuming that she cant get the MSID or what ever numbers you have to edit to be input. I would like to help this person. Thanks guys in advanced.

I will keep googling until something pops up.
