After the last update my amplifier knocks every 3 sec, when I turn on the bluetoof stops. How to restore the earlier version of the firmware, I will add that the connection bluetoof does not work the amplifier is just not visible to other devices, please help.
Thank you for getting in contact, can you please explain the fault in more details, you can always send a video to email@example.com, there is no way to reinstall old firmware.
There are no more details, today I have updated the firmware. The amplifier now seems to be tapping on the speaker every 3 seconds, but when I turn on the bluetoof, when the blue LED flashes, the knock stops when the bluetoof knocking back is back. Bluetoof did not work from the beginning, but I did not need it. That's all. I need this amp tonight what should I do?
