Both on Ubuntu as Windows 11, i don't manage to flash GOS on a pixel 8a. When in normal mode, both fastboot as adb see the device, but after doing "adb reboot bootloader" and the device goes into fastboot mode, i don't get result from "adb devices". "Fastboot devices" does show the device.
I tried to install the right driver, both by the SDK tools in Android studio as manually, but that doens't seem te fix this. In normal mode the device is seen in Windows device manager as Windows Bootloader interface, before as lemobile android device and before that as pixel 8a. I also tried to install GOS with the command line without ADB, but got stuck there on the signing bit.
Can one of you please help me? I really don't understand why adb in fastboot mode loses the device and the web based installer for GOS doesn't work now. Thank you so much!
