Xiaomi Mijia Bedside lamp 2 freezes in manual mode

After updating to firmware 2,0,6_0030, the manual mode stopped working, and if it works, it freezes after a second and you need to turn on and turn off the lamp from the phone to make it work !!! Tell me what to do and is it possible to somehow return to the firmware that was from the factory?

what do you mean by manual mode? The touch panel is not functional?

the touch panel does not respond to pressing, I cannot turn it on and off, I can use the lamp only from the phone

so what should I do in this situation can I go back to the old firmware or is the lamp all dead?
