Pretty much what the title says - I have a FlyAudio G8II system and I've been able to get it to Fastboot mode (which I need because I want to tinker with it a little and need a way of recovery if I screw something up) but I can't seem to find any way of actually connecting it to a computer via ADB - The system has a single type A USB connector, intended to be used for audio playback from USB drives, though peripherals such as physical keyboards also work. I thought that maybe if I try a nonstandard USB A-A cable I may be able to get it to act as a USB device but that didn't work.
My second thought was that maybe it has an additional USB port on the back but I only see a frightening bundle of wires, most of which I have no idea what they are used for.
Is there someone who has a little understanding of this? If I upload a photo of the backside of the system would anyone be able to figure whether indeed one of these wires can be used as an ADB compatible USB port?
