Unable to lock bootloader on Manjaro

bkgrrl00

I am unable to lock the bootloader via the GrapheneOS web installer page https://grapheneos.org/install/web#locking-the-bootloader. I'm getting an error message that my device is not found.

I am wondering if this is because my OS is unsupported. I had originally unlocked the bootloader on Windows with the Edge browser, but I am now on Manjaro Linux with the Brave browser.

Is there another way to lock the bootloader? I'd like to use the Auditor app, but I am unable to do so while the bootloader is unlocked.

bkgrrl00 Yes, you need to lock the bootloader in order to complete the installation process. Was it Windows or Manjaro Linux you used to flash GrapheneOS?

Had to use Google Chrome on Manjaro. Even Chromium did not work for me...
AND you have to use the original cable! Most cables did not work for me either...

meiklmue Update: installing Chrome didn't work for me, but I was able to lock the bootloader programmatically, by following the instructions on this page

TLDR:
I entered adb reboot bootloader
Then I entered fastboot flashing lock
Then I toggled the volume keys to select the Lock bootloader option

Locking the bootloader triggered a factory reset, which I wasn't expecting, but which was okay.

treequell It was Windows, but I've since replaced Windows with Manjaro.

I'll give Chrome a try. Thanks!

bkgrrl00 Make sure you install the udev rules on Manjaro Linux, if you haven't already:

Glad you got it locked.

Yes locking or unlocking the bootloader always triggers a factory reset.
