@dimko Sorry that I see this till now. Did your AC200MAX update the firmware finally?

@veryetti1 I’m sorry your AC200MAX can’t receive this firmware, please contact the after-sale support to repair the screen.

@BLUETTI_CARE I don’t know why, but there still no 4008.09 available for installation via your application. It is still shown that 4008.03 installed and no new updates available :expressionless:

@dimko Your machine version may not be able to get this firmware update, please contact the after-sales department to replace the screen.
