[deleted] Its actually adb kill-server

Thanks, that one got lost somewhere in the fog.

[deleted] How do you add that cool markdown btw?

xgrg

adb wasn't installed before, I installed it now and ran the command and this was the output I got.
"cannot connect to daemon at tcp:something: Connection refused"

xgrg

And of course flashing still doesn't work.

I should probably have suggested this earlier, but I would recommend you join the GrapheneOS chatroom on Matrix, to get support with your install there: https://matrix.to/#/#grapheneos:grapheneos.org

There's a greater number of experienced community members there who can help you troubleshoot your installation issues.

xgrg

treequell Sure I might actually do that. Thanks for the suggestion.

OHB

I'm having same issue, have tried all above.
I'm running Ubuntu 20.4...
Have tried Chromium and Brave
Oddly I did succeed early in the year with Pixel6, now wanted to do the same with another Pixel 6.
Both phones give me this error when I try to "Unlock bootloader".
Have tried 4 cables on both usb3 and usbC ports on Nitro Acer laptop..

treequell

Did you plug the cable into the phone, only after the device was in the bootloader interface?
