[RMX3312] LineageOS 21.0

LineageOS 21.0 (Android 14) for realme GT 2 (porsche), signed with my private keys. This is a vanilla build and DOES NOT include GAPPS.

Thanks to @whyredfire for device tree, kernel and vendor trees.

The build also adds the 3-finger swipe to screenshot feature.

How to flash

Normally, you should use fastboot to flash boot, dtbo and vendor_boot in order to install the LineageOS recovery, then use "Apply update" in the recovery to sideload ZIP file using ADB.

Usually, I do the following :

fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vendor_boot vendor_boot.img

Then, restart recovery to get into LineageOS recovery. In LineageOS recovery, select "Apply update", then select the ADB option and use the terminal to sideload the ZIP file with the following command :

adb sideload lineage-21.0-20241208-UNOFFICIAL-porsche.zip

You only need to download the above mentioned files (normally). Other files have been uploaded for other (personal) uses.
