OxygenOS 4.5.14 delta update for modified system partition

I don't feel like downloading 1.6GB just for 60M update, so this is partial OxygenOS OTA update converted into file based patch using xdelta3 so that it works with modified system partition. Every file is checked by its md5 first before patching to prevent incorrect update.
Notes
the stock recovery (recovery-from-boot.p & bin/install-recovery.sh) is not included in this recovery, so it will not overwrite your TWRP and there is not need to reboot to TWRP after appying the update
text files are not patched but installed full
files in lib/modules are installed full
first boot will takes longer time than usual
Requirements
You should be on stock OxygenOS 4.5.13

How to install
reboot to recovery
backup boot, system, data
install firmware.zip
install system.zip
install boot.img
install any custom kernel
install any mods that modifies the ramdisk e.g. magisk, supersu, dm-no-verity.zip
reboot

Flashing /system not working

Hey guys,
I followed a guide I found to root my G6 (ALI): https://forum.xda-developers.com/moto-g6/how-to/guide-twrp-root-magisk-installation-t3816569 and now have an unlocked bootloader, magisk installed and TWRP as my recovery.
I have flashed TWRP to recovery on my g6. Whenever I try to flash a custom system image I made (I wipe cache and data), or modify /system in TWRP, everything looks fine in the TWRP file manager. However, when I go to boot my phone it takes longer than usual to boot, encrypts my files and all the changes I made are undone.
The only thing that has successfully modified /system was the magisk manager when it patched my boot image.
What is going on?
Thanks.

There is a more actual thread around the Mix 2 Forum. Try to search for it over Google, it provides more actual Vendors if i'm not wrong

Hi all! has someone managed to install and use the Pixel experience GSI image? It's stuck on the google logo loading screen for me, maybe i need another vendor?

Same issue here - the last working version is from March 2019.

If I put a gsi with a vendor from custom firmware, will my phone die?

/system corrupted

Hello, last night I have unlocked the bootloader flashed twrp -0 official build and magisk it was all good and was working then i wanted to install the last eu beta and flashed but flashing it always corrupting the file system, to solve it I have flashed stock rom via fastboot
Problem here I do not wipe /system directory but whenever I try to flash a custom rom the file system directory is corrupting and consequently the device is stucking on twrp. Is there an idea?

1. It must to be in QUESTIONS & ANSWERS and not in GUIDES, NEWS, & DISCUSSION.
2. What exactly corrupted? There is system partition which is not file system And there is a data partition which you can call a file system
3. If the problem was in system partition you would be stuck in fastboot.
4. What steps did you make after flashing stock rom via fastboot?
For flashing eu beta ROM after flashing stock rom via fastboot, the steps are:
1. FORMAT (not wipe) data.
2.Wipe cache/dalvik cache (don't wipe system or flash a ROM without reboot).
3.Flash eu ROM.
You can try another TWRP for example: https://forum.xda-developers.com/Mi-9/development/recovery-unofficial-twrp-xiaomi-mi-9-t3905825 , official TWRP is based on it or from Chines team: http://files.mi-room.ru/files/twrp/cepheus/3.3.1-1030/recovery.img . Both very good.

Update: after format, it stucks on twrp(directories are not encrypted), and rom is not flashing at all I mean it is not writing to /sdcard (loading screen says it successfully flashed but not in the reality )and there are only 'obb' and 'TWRP' directories in the /sdcard also the twrp version is not even change by fastboot or flashing img after a reboot it recovers itself to build -0
I will try it with the Chinese teams's twrp build for this time
Solved with another twrp version

I compiled the official kernel for Realme X2 Pro but how do I install them?

I was able to compile the realme X2 Pro's official kernel release from https://github.com/realme-kernel-opensource/realmeX2pro-X3-AndroidR-kernel-source and I got 3 files generated in arch/arm64/boot folder.
They are:
Image
Image-dtb
Image-dtb-hdr
I just wanted to know how to move further to be able to flash just this kernel (I have a GSI image flashed on /system from TWRP).
Based on the partitions I saw from TWRP, the ones I feel relevant are: Boot partition, Dtbo partition, Vendor Image partition. Which one is it and how do I package the kernel/device tree blob file above to be able to flash to one of these via fastboot? Is that even a valid operation?
I don't want to risk a trial and error approach and possibly screw up further (I have backups of these partitions, but still I'd love to get some insights from the community who might've done this before)
Thanks!
