Px6 upgrade MCU and DEAD!! Help me

[Fumero89]

Hello friends.

A little over 1 year ago I put a 10.25 ”Chinese screen on my bmw e84 with android 8.1

Everything was working fine, but a couple of days ago it was stuck and I had to turn off the car to restart it and yesterday it did it again.

This morning I got in touch with the aliexpress vendor to comment on everything and he told me to update the MCU and he sent me a file, mcuupdate.bin ...
So I put it in a Pen and it updated perfect, it reached 100% and when it turned off .. it has not turned on again ....

I tell the seller, he sends me another file: px6_format.zip saying that with that it restarts and everything remains the same.

Does nothing. The only thing that adds two folders to the usb, android and logs .. (signal that is still alive)

The seller doesn't answer me anymore ...

Does anyone have any idea how to fix it?

Pd: I pay whoever comes up with the solution.



Thank you!!

Hi Fumero89,

I cannot guarantee success but I have an idea you might be able to try to fix your head unit.
I assume you have the head unit(HU) with an SD card slot and a little hole on side of the unit.
Steps:

• get an SD card, format it to Fat32 then copy your renamed "update.zip" OS file which you want to install
• get a pin which you can press into the hole next to the SD slot (e.g. a push-pin you got to your phone)
• with the ignition off, put the SD card in the HU slot
• gently push the push-pin to the hole (you might feel a mechanical click - it should be a button in there)
• while pushing the pin thus the button turn on ignition (HU gets powered up)
• release pin button after some seconds (try any from 1 sec to 10 sec)

If you see any image on the screen after the steps above PM me again and we can continue.

Good luck! :fingers-crossed:

Hi friend,

Thank you very much for the interest you show in helping me.

In the slot of my screen there is only an empty hole, there is no microSD reader nor is there a reset button ...
