I am a first time Android user. I just got an LG G3 at AT&T. Being comforatable with unix/linux based systems I quickly rooted the phone and installed a few different ROMs looking for one that worked.
I settled on pa_d850-4.6-BETA6-20141130 which seems to work really well except for one huge problem: my phone doesn't show up on my PC as an MTP device. It DOES show up as a camera when using PTP. And I can use adp commands from my windows PC.
One strage problem is that my LG G3 shows up under Windows 7 (Ultimate x64) device manager as "Computer->Android Device->Google Nexus ADB Interface" (rather than an LG G3) when connected as both MTP and PTP. Is this a common problem and if so, how can I get my phone to show up as an MTP device?
