Hi Methead,
I wonder if you have built the rom yourself or is it a stock rom? The rom boots on my stick, however, USB does not work. Thus i extracted the kernel & boot.img and flashed with my stock rom. Wifi/bluetooth seems to work, but i dont get 1080p, but it is only 720p.
THanks a lot for any hint,
Best

Same here, The wifi on my device stopped working so I tried many different firmwares, of the same RK3188T model chip, but they don't seem to solve the WIFI problem.

I tried the first methead suggestion, installed the firmware successfuly, and I had no signal on my tv, I tried to connect the device to the PC using the button as usual and didnt work... I shorted the 8/9 ports, nothing.

The pc doesnt recognize any new device, so I can't tried a different firmware now...

I upload a couple of photos of my device, I have a toshiba chip

Any siggestion about how can I conenct it to my PC to try another firmware?
