Sorry, but you where have seen this model in our Sw:
Isn't Supported yet for Unlock Sprint CDMA.
You will have seen M7_U/UL/CDUG/CDWG but any WLS, so i'm sorry but you have done the Error.
We will try to add this model as soon possible
For you problem search in forum, i think just reflash Good Sprint ROM....
