Installation

Device packages have not been upstreamed just yet, so you can't install postmarketOS right now.

Current status

This device uses GKI 2.0 with its usual shenanigans. Usually on GKI 2.0 devices it is possible to use bootimg header version 2 or 0 to force the bootloader to ignore vendor_boot and init_boot (for Android 13+). However, this device's bootloader is quirky and only accepts bootimgs made in a certain way. If the "malformed" bootimg is flashed, the device goes to a glitched Download mode with either an "error verifying vbmeta" or OEM Lock being "ON" (despite having turned it OFF by unlocking the bootloader).
