I buy brand new unlocked pixel 8a from major retailer stuck at unlock bootloader

Rand-Uzer

spring-onion Laptop has no usb ports, When I run command " ssh-keygen -Y verify -f allowed_signers -I contact@grapheneos.org -n "factory images" -s DEVICE_NAME-install-VERSION.zip.sig < DEVICE_NAME-install-VERSION.zip" ...

I get this ...

$ ssh-keygen -Y verify -f allowed_signers -I contact@grapheneos.org -n "factory images" -s DEVICE_NAME-install-VERSION.zip.sig < DEVICE_NAME-install-VERSION.zip
Couldn't parse signature: missing header
sig_verify: sshsig_armor: invalid format
Could not verify signature.

so it would seem I have failed again

Do you mean, download Debian 12, flash iso, install on usb flash drive run as live disk no install?

de0u I did skip the unlock bootloader bit as it is unlocked. In Fastboot mode down below red triangle "Device state" is "Unlocked" should I redo these steps despite it already being in "Unlocked" status?

spring-onion

DEVICE_NAME and VERSION are gaps you need to fill out, since you're using an 8a here are the commands:

curl -O https://releases.grapheneos.org/allowed_signers
curl -O https://releases.grapheneos.org/akita-install-2025040400.zip
curl -O https://releases.grapheneos.org/akita-install-2025040400.zip.sig

ssh-keygen -Y verify -f allowed_signers -I contact@grapheneos.org -n "factory images" -s akita-install-2025040400.zip.sig < akita-install-2025040400.zip

bsdtar xvf akita-install-2025040400.zip
cd akita-install-2025040400
bash flash-all.sh

spring-onion Something is going down, reboots happening

Rand-Uzer

spring-onion ok, seems to have completed all the commands you gave me in your last post so what now?

Rand-Uzer

spring-onion

SUCCESS ... Thank you so much everyone who helped in particular spring-onion for going above and beyond in helping me.

de0u

Rand-Uzer If flash-all worked, then the directions on the web page say "Then, proceed to locking the bootloader...".

Rand-Uzer

de0u I'm doing a terminal install, so unsure what to do next

spring-onion

fastboot flashing lock

That's the command, confirm the action on the phone and you're done. You can then boot into GrapheneOS and verify the integrity of the operating system, for example via the included Auditor app.

spring-onion

Enjoy! 😎

spring-onion I really can't thank you enough, took 5 hours from when i first started, so much for YT vids from David Bombal and Naomi Brockwell and there 8 minutes lol great channels but ... that wasn't remotely true for me. Are you a Graphene Dev or a super user? You have uber skills the last post of commands you supplied got me over the line :)

spring-onion

I just have plenty of experience with helping people troubleshoot installation problems, I've seen it all.

GrapheneOS

@secrec Fastboot does not require root access. It requires having udev rules to use it as non-root which is covered in the install guide. The issue is either that they skipped the instructions about udev rules or are trying to use a Snap for Brave / Chromium that's unable to access USB without special configuration due to being improperly turned into a Snap without accounting for WebUSB. Snap lacks a way to actually request access to a USB device or even USB in general so there's no way for the application to handle it. Users should not have to run CLI commands to grant access. It's a broken approach. It's why we tell people not to use a Chromium Snap.

secrec

GrapheneOS Yes that is an alternative, but its over the top to do the udev rules just to install grapheneOS. Far far simpler just to run fastboot as root.

GrapheneOS
I installed Brave via CLI not a Flat or Snap and still had problems.
The alternative commands that spring-onion supplied got me over the line.
