What can go wrong went wrong today.
I tried to flash 2 Pixel 6a.
But now both are stuck in fast mode mode.
Probably because of bad USB connection and / or wrong driver in boot mode.
adb had worked:
adb reboot bootloader
device started in boot loader mode,
start flash-all.bat
Errors
FAILED (status read failed (Too many links))
…
Now both devices are in fastboot mode
and the only thing that works is the barcode display, nothing else, no restart …
And the devices are no longer recognized even under Windows I connect it.
