Dear GrapheneOS Community,
I followed the web-install on a brand new Pixel6a with the same Setup (Linux PC, USB-Cable, ..) I used two months ago to successfully install grapheneOS on a Pixel4a (just to avoid question about the HW I used ;-)
On the step "unlocking the bootloader" it gave me an error message -> failed to unlock
I tried again and it did not finde the device again
Now the device ist in the fastboot mode scree where I can change the option with the volume up down buttons, but I can only comfirm the "BarCode" option with the power button (barcode screen will show).
On all other choices like restart, start, recovery, .. the power button does not seem to work! The options are not selectable!
I also tried to reconnect to the device via the command line:
fastboot version 34.0.0-9570255
Installed as /home/markus/platform-tools/fastboot
markus@pc:~$ echo 0 | sudo tee /sys/bus/usb/drivers_autoprobe
markus@pc:~$ fastboot flashing unlock
< waiting for any device >_
but it does not find a device.
Any help will be greatly appreciated and please forgive strange wordings or mistakes - english is not my first language.
