Get PX6 into MASKROM mode

[vlad.presada]

Hi there. I'm having a problem with my navi. Px6 4gb+32rom. It's trying to boot, loading just the image with the logo for about 10sec, after that a split second it shows "no signal", and then restart. It's doing this forever if it's powered. Seller sent me a zip file to flash it, but no success. Tried also on the microSD, same, no luck. Tried also different combinations of the reset button, but same, no luck. Reset seems just power of button, in case probably some apps freeze or something, just not to power of the car, you just can power of quickly with the "reset" button.
I have been reading for a few days already different topics and i can't get my head around them, maybe here in this topic it's what i need to fix it, just need some small guidance from you guys.
So, my SoM seems (and it is) different from the ones posted above.
1. Is it still available the OTG workaround for me?
2. How can i force the navi to recovery?
3. If i need to flash the SOM, i don't have an .img file, i only have a .zip file, is there any general file that can be used, or it should be something specific for my navi?
4. If the boot is damaged, i saw some rockchip tools to read the existing files, is there any chance i can recover my specific files from the SOM so i can use them to flash it again?
Probably i will come up again with questions, thanks in advance for any help.

I can post u the link, but my navi it NaviFly. My guess is that almost all the same. Just wait me few minutes so i can upload it to my dropbox and share it from there.

This is for NaviFly, bmw e83, px6, 4gb ram+32gb rom. Android 9.0.

Maybe i have all what in need in the archive, i don't know, so i can start flashing the SOM. Or maybe some advices from others on where i should start...

Did you guys end up finding out how to turn the update.zip into update.img? I'm stuck on that situation too :/
Bootloader and recovery are all gone (system too of course).
I'm still trying to see how to put it in maskrom and what pins to connect the cable to ;(

When I wrapped the white and green wire with aluminum foil, the PC recognized the SOM PX6

On "otg-2.jpg", what are the 2 yellow wires "12" and "16" good for?
EDIT: Found out from other threads: These are the 1.8-3.3V for Recovery and OTG detection via voltage-divider resistors.

Hi people , I have a px6 based one with this board and it was given to me as the previous owner tried to update magisk and now it's stuck in a boot loop showing android, anyone knows how to enter maskrom or anyway to recover this unit ?

Hello,

I flashed my Android unit by accident to A11. I have Xtrons 10.25'' PX6 RK3399.

I read a lot on this forum about getting to MASKROM, but i think im doing something wrong.
I made a cable like this :

its connected it like photos posted by user in this thread - 3/5/17 and 12/16/17
Im making a short circut on these two gold "pins" then PC is starting see my board
I installed whole drivers, adb , rockdevtools but my PC is not recognizing a device and i have error - Unknown usb device (device descriptor request failed). When i'm trying to push diffrent driver(rockchip or adb) i get a error like these drivers are not x64, but i checked it and they are xD
My OS is Windows 11 Pro 22H2

When im connecting my Android Headunitin the car i have only black screen, and i dont have any buttons to go to Recovery or smth.



Here you have photos of my motherboard :

Any idea what can I do with this ?
