Code: 
/*
 * I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...). 
 * Please do some research if you have any concerns about features included in the products you find here before flashing it! 
 * YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you. 
 * Your warranty will be void if you tamper with any part of your device / software.
 * Same statement for XDA.
 */

LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

The boot.img included can't pass whatever the f**king check realme is doing.

I also tried to flash the boot.img from India version, it doesn't pass either.
So I'm afraid Realme is doing some damn to prevent us from loading the kernel.

But strangely, the recovery from https://forum.xda-developers.com/re...very-unofficial-twrp-realme-x-stable-t3959556 works completely fine.
So I guess there should be a way to pass that check.

It looks like even with unlocked bootloader, realme X CN variant is still doing some key verification for boot.img.

Thus if boot.img is not properly signed(?) it won't boot on CN variant, thus CN variant needs a different version of LOS.
Strangely, recovery is not verified at all.

BTW, the official ozip update for CN variant is verifying itself as 1901CN, thus current TWRP won't work properly as it's specifying itself as 1901.
Not a big problem, as the model verification line can be easily removed from update-script, then TWRP can apply the converted zip.

I'm thinking the same thing.
Anything that I flash with a modded boot.img will not boot (error message)
So I then have to reflash the original boot.img via adb just to be able to boot back into twrp.

The CN version definitely has some extra security in the boot.img, and it's quite disappointing.
