I have the same problem with my lg K7, it's a T-mobile device. Mine works only the 2G / EDGE BAND. I did unloked the bootloader, also tried build.props but nothing changed, it seems that the other bands are still locked by the manufactor.

Is this the 3G or 4G LTE model?

It does not work with certain bands because the flashed modem on the device doesn't support those bands. This is an OEM problem that would be fixed by a custom rom.
