Hi all!
I installed the above unit 2 years ago. Everything was fine. Today, i noticed whenever I turn the headlights off, the screen goes black. Turn lights off, its back on. Not sure if its always done this or not? Anyways, changed display settings to auto dimming. Not I get past the BMW boot logo, then black, regardless of lights.
My MCU is JLY_BML220429A_6125. Version: BMW_OS_1920*720_1.02. Build number: trinket-userdebug 10 QKQ1.200816.002 eng.android.20220402.193509 test-keys.

Does anyone know any way to factory reset it now that I cannot get into the setup screens???? I tried the RESET button on the front. It reboots but no change.
I would also entertain a firmware upgrade! Thanx
