Well, it actually made it worse. The update was successfull:
But after removing the device, the screen goes black. Waited for few minutes - screen is still black. When I click "reset" the image of a loaded os appears for a second and then disappears. The boot screen image also is not appearing (screen remains black). However, when I cycle 12v with reset button eventually the screen comes up with a boot logo and back to the same error cycle with "Wait mcu reboot failed" error, and after 2-3 minutes boots into OS with same things not working (sound, BT)
Here's ver info screenshot after "flashing" mcu:
Does the Bluetooth phone work, please?

No, Bluetooth Phone doesnt work, and Android Auto doesnt work (head unit is not appearing in the BT search), amplifier doesnt work (no sound, can not adjust volume)
Wi-Fi works though.
Also, when the unit was new out of the box and I was connecting it same way on the desk, cooling fan was turning on often. But this time it does not turn on at all.

If the situation is the same, the hardware inside the machine is damaged. Please contact your salesperson for after-sales service
@DUDU-Meng
I wonder if I should try to flash the latest beta? Or should I start a warranty process?
