Here's the situation, I have a T-Mobile Sgs 2, I need to unlock it for a different SIM. The phone is rooted, the superuser app is there. I would download an unlock tool, however, whenever i try to "Add a Google account" to get to the Market, I get an error "Can't establish a reliable connection with Google servers" (did this on a WiFi connection, many many times). So I'm left with one option, to get the code myself from the nv_data.bin. I have the UnlockCodeGen program, but I need to get the nv_data.bin somehow, and i can't find the efs folder in any of the phones directories. How do i extract that damn nv_data.bin? Any info is greatly appreciated!!!!! please, get back.
