XY Auto 8227L / YT9216B - which firmware to install?

Hi,
I own this 10" horizontal 1024x600 head unit.
In car settings reports YT9216B_0002_V004_20190728 / 8.1 GO (yes, sure) / XY AUTO 3.0 / MCU 3.1
CPU-Z reports model as 8227L_demo (full_8227L_demo) / 1G RAM / 16G ROM
On XY Auto website in 9216B-8.1Go (old software) there are three subfolders: UI1, UI2 and what google translates to True 2G (contains again UI1).
Which one should I select?

9" 2G/32G 1280x720 Android Head Unit recovery process

Greetings!
I'm having the below 9" Android HU (advertised as T8 by the seller), came from Ali's vtopek store.
I used for a month, and now the Android is not booting anymore. During the boot process, I could
only see the Android robot logo for a couple of secs, and then the screen turns to black.
The device needs recovery, however the vtopek store is not willing to support my problem, and I would
like to turn to this great community.
Does anybody has a working recovery process and FW for this model?
Any help appreciated!
