Firmware

AXP.OS for the Google Pixel 4a includes the latest available bootloader and modem firmware so there is no need to do anything but flashing AXP.OS - at least if you carefully follow the Install guide in the next topic.

Install / Upgrade

See: Install on Pixel

Setup AXP.OS

Follow Setup

Re-locking the bootloader

Supported: yes

Follow Bootloader-Lock to lock your device.

Fingerprint information

On boot you will see a fingerprint or "ID" which ensures the AVB signing key used is trusted.
Some devices print a minimal ID of 8 chars, while others print the whole digest. For more details and example pictures see here.

This fingerprint is unique for each device AXP.OS build for but won't change during updates (without a notice at least).

Here are both ones for sunfish:

BOOTLOADER minimal ID
        2357DB9E

BOOTLOADER full ID:
        2357DB9EBF8090F9
        908E9BBC0B353CC9
        CA11015AC588001D
        0AB9A80BD8AA5906

If you see a different ID during boot you should immediately request support and stop using the device!
