WebInstaller and Unlocking the Bootloader

Djack41

Hi, I have a problem with the Pixel 8a, trying to install GrapheneOS

The OEM unlocking is enabled, as the USB debogging.

I booted as recommended on the webinstaller in the bootloader interface, I have the message Fastboot Mode (red with the red triangle), and Device state : locked (in green) unlockable (in red)

Then when I try to "Unlock bootloader" on the webinstaller, it doesn't even find my Pixel 8a, and display the message "no device found".

I tried several times, with the Google USB-C cable, on Linux Mint 22, and then on Windows 11 - Chrome webrowser, all updates installed.
I’ve just tried on MacOs with Chrome browser (all shields disabled and no other app opened), same result.

Thanks for any insights !

Djack41 as the USB debogging

For reference this is not needed to use the web-install, and not recommended to keep on. So make sure you disable USB debugging.

Also, did you follow all of the post-install steps, relocking the boot loader, verifying the Verified boot key hash, and disabling OEM unlocking, etc?

Problem solved, I needed to get a « data cable », not provided with the phone
