I would post screenshots, but unfortunately not enough posts to do so.
Is this some incompatibility with the phone and the ROM? Or is it some other problem I can solve?
I finished flashing Liquid Kitkat 3.0 NIGHTLY onto my GS3i747, and everything's working fine for the most part. But I wanted to connect my phone to my computer as MTP. PTP works, but with MTP, it doesn't show up on my computer. I went to go check if USB Debugging was checked on, but in fact there was no USB Debugging option at all.
