Boot modes

Each device has its own method to access its special boot modes, see:

Firmware

AXP.OS for the Fairphone 3 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

Install (A/B)

Setup AXP.OS

Follow Setup

Re-locking the bootloader

Supported: yes

Follow Bootloader-Lock to lock your device.

Fingerprint information

On boot you might (some devices do not show it) 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 and flavor(!) but won't change during updates (at least not without a notice).

Here are both ones for FP3.

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