Idk if it's any relevant but i can confirm that stock camera on Realme UI doesn't work with Linage kernel from 17th and 20th but it worked before lens changes (On 12th release). Not that big of a deal for me, i can use some other app but i'm currently testing my stock based clean rom for CN version and i would like to upload it with your kernel (With all the credits obviously). Is there a way to fix this?

@karthick mostwanted Are there plans to bake ntfs and exfat support into this so external hdd and sd memory can be accessed via otg in the future without needing third party apps?

More to this there seems to be a general OTG problem. When I connect a usb drive (formatted as fat32) I can see it for about 5 to 10 seconds. During that time I can see all files and play music off it. However it then disconnects and only shows up if I disconnect and reconnect the OTG cable. I have tried two different OTG cables and two different usb drives.

Nevermind it was my charge limiter module that interfered with OTG.

OK folks, need your help. I have tried the below steps and the phone is rebooting into recovery. What could be that I have missed and how do I fix it. I appreciate any pointers, thanks!
So, I have started to look into using a custom ROM as the stock one is pathetic, to say the least. Since LOS is available, that was my first choice. I did the following and end up with a bootloop.
1. The X2 Pro was running version C27 software
2. Unlocked the bootloader
3. Installed OrangeFox
4. Downloaded and flashed the LOS from the OP
5. Format data
6. Downloaded the suggested GAPPS and installed
7. Reboot system
After this reboot, I still see The Realme words in White with Powered by android at the bottom. And as I had feared, the phone reboot into recovery. I tried the steps mentioned above once again only to get the same result.

After TWRP flashed (i'm using TWRP 3.3.1-13 not OrangeFox), you have to format DATA first >> reboot to TWRP Recovery again >> then flash LOS >> then flash GAPPS (I suggest nano GAPPS) >> reboot recovery again >> flash Magisk 20.3 if you want.
These steps I followed from RealmeUI C27 and successfully installed latest LOS. Good luck.

I flashed the most recent version.

I'm missing the gestures for going back / going home:
swipe from bottom = home
Swipe from left / right = go back
No option like that under System/ gestures for me, I don't have any full screen gestures settings

And I also don't have a recent apps screen. When I click on the square button, nothing happens.

Thanks for the steps man! I tried it again and still nothing. The phone is still booting into Orange Fox recovery. Shall I go back to the stock, C27, and start again? If yes, is there any guide for that?

OK, so here is what I did next.
I flashed the vendor partition again. Then wiped data. Then proceed with LOS and GAPPS installation. Once done, rebooted to LOS successfully.
Now, I can get into the OS but the default launcher - The Pixel launcher keeps crashing. A factory reset is also unable to fix the issue. Still checking what else I can do.

Maybe you should flash vbmeta patched from first post after flashing TWRP, although I didn't flash it. I have flashed Paranoid Quartz before LOS and everything was going smooth.

So, below are the steps I had followed to get this working.
1. Unlock bootloader
2. Flash OrangeFox
3. Flash VBMeta
4. Boot into Recovery - OrangeFox
5. Wipe everything in sight - Data, internal storage, vendor, cache, Dalvik/ART
6. Flash Vendor partition
7. Reboot into recovery
8. Flash LOS
9. Flash GAPPS
10. Wipe Cache & Dalvik (not sure if this is required at all)
11. Reboot to system
Post reboot, the pixel launcher was crashing. I have installed Lawnchair.

The Realme UI was so horrible, it would re-draw the nova launcher everytime I go back to the home screen. This just ruined the experience for me. This is my custom ROM after a while. And I'm loving the Pixel like look and feel. This is exactly how a SD855+ powered phone should behave.

Only issues I have so far are
1. FP is not working. I keep getting error messages that the scanner area is dirty. Then scanning stops.
2. The AOSP camera app is unable to take photos using flash. Even if the Flash is on, all I get is a dark image.

I'm sure other users have been able to figure out a fix for above issues too. Those are not a dealbreaker for me and I'll stick to this for a while. Thanks to the Dev and team for the ROM. Thanks to the other members of the forum for helping me with the issues I had faced during the installation.

Update on 06/28
FIngerprint registration is tricky - it takes a lot of time and effort. But this has been set up now.
Some GCam mod has been installed, unfortunately, do not remember the version.

Try to flash Nano or Pico GApps, micro GApps will install Pixel Launcher as system and will FC repeatedly.
Fingerprint does work on mine but need to be patiently registered as it's not as smooth as Realme UI in registration process.
AOSP camera need to be improved and I'm not using it, currently I'm using Gcam Pixelcam Plus V2.

Yes, I have fixed the issues one by one.
The launcher is already fixed - using Lawnchair.
