How to Solve Xhorse Multi Prog Device Authentication Failed?

 Problem:

It failed to do Xhorse multi prog firmware updates and now is says upgrading but nothing happens.

I tried reset button but same problem.

Software display error “Device Authentication Failed”. Any solution?

Solution:

Xhorse engineer suggests sync authorization to see if it is normal.

If you can sync authorization, try again. If not, restart the multi prog device and software.

 

User solutions:

1). Connect it to USB directly to the computer that has the program, turn off the equipment, turn it back on (with the USB already connected) and update the firmware, it works (it happened to me).

2). Something similar happened to me and i used another PC to do update via the LAN cable and it worked.
