Just for info:
My finger in the ass was exactly this HU:
I've been trying to flash my HU for 14 days now. Surely there were 50 attempts.
Of course I had read every post here and gone through each step several times on my HU. But without success. Well... somewhere in this thread it says that you may have to disconnect the display from the motherboard. I tried to do that yesterday. Said and done. Even so I could not flash. HU screwed together again to think, unnerved, what I could do now.
Then I had the glorious idea of checking every single plug. Here then came the realization. No matter how you connect the USB plug to the box, every USB stick is recognized and you can read it on the HU. That's exactly what's funny, but also the TRAP!!! This is exactly the reason I couldn't flash. I simply plugged in the USB plug the other way around and, what can I say, this stupid box was recognized by the PC with the power trick. Now I was able to flash the box as in the video from the 1st post. No bootloop, no white display.
The firmware could be flashed. After the first start I wanted to change the language and was shocked. I broke something during the displaytrick. I could not operate the HU on the screen. With a mouse on the USB output, I changed the language and performed a factory reset. After that everything was as it should be. All apps were installed, which are in the firmware present and my previously installed naturally gone.
However, Oreo is not displayed in the Androidsettings / System, but it stayed with Android 11.
I didn't feel like flashing the TWRP anymore because I couldn't operate the display. The HU is now in the eternal hunting grounds.
- This motherboard can also be flashed.
- Try to connect the USB Plug the other way, if cour HU is not recognized.
- Don't do the display trick!!! At most you can (probably) remove the connection with the two cables on the mainboard, but that's it. Definitely not the thin ribbon connectors to the display if you don't know what you're doing!!!
That's it for my experiences with this box. Out of anger I ordered THIS HU
(bought via Amazon, where it is cheaper) to punish myself for my stupidity....
