Default No network connectivity

My friend somehow messed up his Atrix 2while doing a factory reset. He gave it to me to take a look, but I haven't managed to fix either of the following issues:
- No network connectivity. Wi-Fi works. But, no signal is detected (2G/3G). The phone is always in "Emergency Call Only" mode.
- When I connect with PC over USB (Mass Storage or MTP) file transfer doesnt work. None of the memory internal contents are shown.

This is an India unit (Asia Retail) with official Android 4.0.4
