Hi @All,

i hope you guys can help me. I just bought and asembled the android radio into my car. Everything worked fine besides bluetooth (lost connection everytime after 5 seconds)
Anyhow, i changed a (bluetooth) setting in the advanced settings menu after that the android screen where frozen. After pressing the hardware reset botton for 15sec. , the android gui disapeared.
Just the orgioninal (old BMW gui works), touchsreen without function

The supplier send me the image of the firmware to fix the issue, but the device dosent boot from USB nor from SD. Do i need to try to boot from a bootable Android 9 SD (USB) first and then choose factory defaults
and use the image from the supplier for that? USB /SD format FAT32, ore does NTFS also work?

Many thanks for your help

Best Regards

Sven

Hello,

The usb drive /SDCard has to be formatted FAT32 and the partition should not be larger than 32 GB.
On some models the devices do not boot from both USB ports (red and yellow) only one does work, try both.
Maybe it also helps do disconnect the car, and boot the device only from Power without the car.

Did you only get an OTA Update file or a complete OS image, can you upload it somwhere for check ?

Hi Chri,

thanks for your reply, i tried both usb cables, i used fat32 and the USB stick has 16GB the sd card 32gb, i also disconnected the battery.
i havent tried, if the device will boot when i disconnect the battery and put it back on without turning on the ignition. I will try this now.

Best Regards

I have both the PX6 image aprox. 800MB and the MCU as well

Edit: also dident work

maybe i wrote a little bit misunderstanding ^^"
i with disconnecting the car, i meant it different.
what i wanted to say is to only have power from the car or a powersupply connected to, normally the Unit does as soon as it got power.
another thing you can try it to disconnect the original navigation cable that goes to the android display, to enshure it will only have it`s own source.
does it show no image at all anymore ?
Do you have an USB A-A Cable to connect it to a computer to see if it will be found at all ?
Did you maybe have activated USB Debugging some time ?

i would be interrested in getting the files

sincerely Chri

Just to give you a feedback on this issue, i got a new PCB from the supplier.

My failure was, that i pressed intuitiv the false botton. "Update Config" instead of simply reboot
