Im in the exact same situation as you. This is what I have found:
Apparently, devices as the G2 with Qualcomm CPU's can unlock bands, and to do so you need to follow this:

BUT, the funny thing is that i cant get the G2 into "DIAG mode". And thats what is stoping me from doing it.
If you find the way to enter into DIAG MODE, tell me
