Stream Dock stopped responding to anything after an unsuccessful firmware update

Argus_15

Hi! I have a Chinese version of the stream dock Ajazz akp 153. I found on the forum (not this one) how to reflash and tried to repeat. As a result, some error appeared and the stream dock just went out. Does not respond to anything. But when I connect it to the computer, I hear the sound of a new device. Can you advise what to do? How or where to find the firmware (any, but if possible the Russian version) and the program for flashing. Thank you!

Firstly, we do not recommend customers to flash other versions of firmware programs themselves, as it is easy to encounter the phenomenon of not being able to do anything after unsuccessful flashing. If the screen does not light up and there is no response when pressed, it can only be returned to the factory for repair
