I bought a new box. I install everything and I try an ISP connection and it gives me cmd error. Dissolve the EMMC I try it with the socket and here's the same problem. I start by saying that I have tried all the solutions of the forum followed also the video of the Socket. the EMMC is 100% working, I have also tried others.
the box is connected to external 5v power supply. I can not solve the problem, I tried all the solutions on the forum but it still does not work
