Support needed - unable to do FW flash

[pospanet]

Hi,
I just received AI vision kit and as it had ROM version 0.2xxx I have tried to flash it first. Unfortunately, it breaks during the update and kit is now in weird state. When I list all USB Connected devices kit identifies itself like „Qualcomm HS-USB Diagnostics 900E“ with No LEDs on. If I try Factory reset by holding reset for 12+ seconds, device disconnects from USB, then re-appear as „Qualcomm HS-USB Diagnostics 900E“, all LEDs goes red for couple of seconds, then goes off again. „adb devices“ commands showing no devices. Has anyone experienced something similar, please? Do you know how can I finish the FW flash or is the device bricked forever, please? Thank

BR,
Pospa

Did you fix it?

I believe it has to do with the Qualcomm USB driver not being oke. Not using the Qualcomm stuff. I debugged the .bat file it and it runs into error on:
adb reboot bootloader
fastboot devices

If you look at Google Developers documentation with same issues, it looks device driver or debugging through USB is error. I am now on Windows 11, on Windows 10 it works (also with issues). So I might try to upgrade through WSL (Linux) or installing correct device driver. I found one at Qualcomm, but you need to register and have an account over there.

Maybe it is not the driver needed, but it is at least a try.
