Unable to flash GSI system images in the tablet Teclast T40 Pro

[rogergithubbing]

Current Behavior:

I start always with a completely fresh installation of the original system.

I flash from Windows 10 connected to an usb 2.0 with a very high quality cable.

After flashing I get the crDroid logo loading forever, or a constant bootloop without even entering crDroid loading screen
Happens also with other gsi roms I have tried, vanilla, with gapps, without them... etc. no gsi rom seems to boot correctly.

I also have the doubt that in some gsi roms I get the message FAILED (remote: 'Not enough space to resize partition'), so I have to choose other gsi rooms smaller in size, and I would like to know how can I fix that, too...

Describe the bug

device do not boot after flashing

To Reproduce

fastboot devices
fastboot erase system
fastboot delete-logical-partition product_a
fastboot flash system C:_Dades!Teclast_custom*crDroid-10.5-arm64_bgN-slim-Unofficial.img*
fastboot -w

if I issue this command, I get a bootloop without entering crdroid load screen; if not, it gets stuck on crdroid load screen:
fastboot --disable-verity --disable-verification flash vbmeta C:_Dades!Teclast_custom\empty_vbmeta.img

fastboot reboot

Expected behavior

Correct boot of crDroid (and other os like lineage, xperience, etc. with Android 14,13,11

Smartphone (please complete the following information):

• Device: Teclast T40 Pro ID T1A3
• Build Flavor: system-arm64-ab.img.xz
• Version Android 14, 13, 11... (the tablet comes with Android 11)

Additional context

This is a capture of the results for the operation in Windows, using the latest platform tools from google and windows 10:
Do not forget that I sometimes apply the fastboot --disable-verity command, some other times not, and that I get the bootloop described above depending on it.

I attach the logcat captured from the crDroid stuck in the loading logo. I hope it helps.
