Trying to troubleshoot a friend's M7. It froze up on her, so she did a factory reset. After that the WIFI and Bluetooth both refuse to turn on (I switch it to on, but after a few seconds it just switches back to off). This wasn't a problem before the reset. I flashed a ROM to install monster updates (only way to update it without internet connectivity). That worked fine, but the WIFI and Bluetooth still don't work. I removed the back as you instructed to take a look at the WIFI antenna, but nothing looked loose or in need of solder, etc.

Any advice?
