[Q] Android Car Stereo Head Unit massive problems

Hey there guys!
I bought a Unbranded Android Car Steoreo Head Unit and it went pretty good in the first place.
After i installed spotify and downloaded music, once the Wifi wasn't availiable anymore, spotify told me that the USB-Storage is no more there (but it is).
I thought a upgrade would solve this so i googled and found this Thread:
"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit
As my Radio says its also a AN-21 U i thought it will work.
This is my Radio by the way:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So after updating the MCU it lags a little bit and the volume-knob and the +/- knob is changed with each other and not responding proper either.
I also tried to update the System but activating this just boots up the device saying update start and update end at the same time, not taking any affects.
Software System Reset is not solving this, and im not abled to enter the boot menu (By pressing power on + vol up butten (i tried both knobs after MCU update)).
Do you have any idea for what i could do? I would really appreciate your help because im not able to solve it myself.
Thanks!
PS. Sorry if this is the wrong area

PX30 Android 10 Bootloop

I have a AmaseAudio Android 10 PX30 Head Unit and I was looking around for root options.
I managed to enable root over ADB with it being detected as rooted and working perfectly but then when I rebooted the head unit, it would not turn back on. It shows the first boot logo but then black screens. I can access recovery fine but tried wiping the data but it doesn't seem to boot still.
I have contacted the manufacturer for the firmware as I don't see it anywhere online since it's PX30 and Android 10, although I do see Android 9 PX30 that I might try.
While I wait for their reply, I tried installing MalayMod and Hal9k for PX30 but the install fails in recovery with Error 1001 Status 7. I have researched and it seems to be because it's the stock recovery and broken root.
Any other ideas or ability to install TWRP or something on PX30?

Is it MTCx, post MCU version including prefix.

Upgrading the MCU seems to have removed the factory settings.
I would like to receive factory setting data.

What happens when you configure factory settings or apply the config backup you took before applying an MCU update file.

Is this an MTCD type device? Post screenshot of MCU versions.
Assuming it is MTCD, what options have been tried from the plethora of posts regarding recovery.
