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, Qualcomm's updated SM6225 ABL for Android 13 only accepts an uncompressed GKI kernel binary and enforces vendor_boot and init_boot. When this device tries to load a non-GKI binary, the device goes to a glitched Download mode with OEM Lock being ON (despite having turned it OFF by unlocking the bootloader).
