Hey Fred, is it possible to modify MCU so rear cam stays active for longer?

So i think that you can have success by deleting app ids and updating the list.
You can try it .
I managed to do it as well by updating the /data/local/mapapklst.txt file.

I only struggle with the volume settings of my device. The navigation output from the left speaker is now very loud and when I get a call (it also only comes from the left speaker) the volume is very low although I set the volume in the audio settings to max for calls. Do you have any idea how to set all the volumes correctly?

If you want to watch downloaded videos, you can use MX Player to set screen aspect ratio if video is not in our aspect ratio which is 2.39:1 I think.
Thank you . I'll try

Recovery mode does not help because it has no hardware buttons to move through the menu.

only way would be via ADB, has usb debugging been activated at some time by you ?

There is one way: if you have Android 7.1 rename px3.img to px3_reset.img, if you have Android 8.1 rename px6.zip to px6_format.zip. Upload to USB flash drive, insert into slot. If you have an SD card inserted, remove it. Connect power to the unit. The factory reset should be complete. Unfortunately I don't have Android 9, so I can't help with it....

But this is not for all MCUs, right? Or is it universal?

In my opinion it has nothing to do with MCU, it's an android daugther board thing: hxxps://github.com/chinesebmwheadunits/chinesebmwheadunits.github.io/wiki/Hardware

however, each android daugther board has its own firmware, eg you cannot use px3 for px6 and vice versa, even if they are mounted on the same MCU !!!

once in recovery, scroll should be brief press of reset, select long press.
Anyway, my platform is NOT px3 nor px6, it's a "newer" snapdragon 625 , not a rockchip. So no way for me with the well known zip in the wild, I need the recovery to format and do a full wipe, or do anyone have the correct zip for snap 625 android 9 headunit?

It happened I set the screenlock pin (my google account is under mdm so I need it) and now the unit doesnt recognize it :/

I just received and installed unit, don't have any update files.
For now I have problem with
- not working simcard
- bluetooth can't connect with my iphone
- I can't choose any custom navigation app to make a "navigation" shortcut (except googlemaps.. but I am not using it)
- My usb DAC is not working with this unit... sound is dissapearing after connecting do USB port

EDIT. I have fixed problems with USB DAC by removing internal AUX connection between android and CCC.

I already tried messing with the Factory Settings but no luck. Any ideas?
Hello guys , I have got the same issue as described above, "no signal" on BMW OEM interface.

Any clues of what may cause this kind of behaviour ? I have check the LVDS connector which is correctly plugged.

Thanks

unplug/replug all of the connectors, be sure they are properly connected, I had this problem too, due to a bad connection.

Hoping someone can help here as google has let me down.

A firmware update has left by 7.1 AVIN unit dead. MCU is fine but SOM has lost its image and when I swap to the android screen, I get "No Signal" Reversing screen is working away fine, as is the idrive, so the underlying MCU looks ok.

I have tried bootable USB, booting SD, renaming PX3.img to PX3_reset.img, format etc

I have concluded that the SOM is wiped completely.

Does anyone know a source for a replacement SOM? Mine is a ZXW_870 and Ver_03 with 2 rows of pins on both the top and bottom of the module.

Any pointers would be much appreciated.
