Requirements:
--> a non-AOSP port made for Poco F1 which supports custom kernels in permissive
--> The first line of updater-script must be removed (otherwise, the ROM will not be flashed)
--> beryllium2dipper-patch (for Ignition 4, the specific one)
--> permissiver
--> a custom kernel (usually, without system_ext support)
Bugs:
Normal GPS, instead of dual (Poco F1 has normal GPS)
NFC (system is not being patched)
Sometimes, Always On Display (different files on different ROM's)
