Hello, I previously put GOS on my 7a back in '23, and I know I had some weird issues, but I'm hitting a wall now.
I've followed both the web-based and CLI-based instructions to the point of unlocking the phone, which is where my problems begin.
I use Arch Linux and Firefox, so I downloaded Chrome to do the web install because the CLI was originally giving me FAILED (remote: 'flashing unlock is not allowed'), which I remembered from the 7a days was due to not having the sim card inserted. I've now reacquired a sim card and put it in the new 9, and now it gives me < waiting for any device >. But the web install has given me the same issue: I click the Unlock Bootloader and it asks which phone (and shows the 9), then responds with Error: Bootloader was not unlocked, please try again!
This is the phone I got, so it should be carrier unlocked. I'm in Fastboot Mode, fwupd.service is never loaded (running the stop command states that it wasn't running), I have android-udev and android-sdk-platform-tools-common installed (as well as a few others, but please ask as I'm not sure which - they should all still be there from the 7a 2023 install), and... what else?
Running "adb get-state" results in error: no devices/emulators found
Please let me know what else I can provide to help troubleshoot, or feel free to point out I missed something obvious? Thanks!
