will this reset my phone? and this will 100% work? will it eventually solve my network problem?

- It won't reset your phone
- It will work 150% to restore your STOCK kernel
- I don't know why your network has a problem so I don't know, the question was just how to restore to the stock kernel and I gave you a solution on how to do it.
And last but not least, ALWAYS make a backup if you have something important on your phone, no one is responsible for your data if you're modding your phone by flashing custom stuff.
so i have jtz extracted the one plus 9 pro ota update with the payload dumper can i use the data? and "boot.img" must be flashed into 4 different areas?
After a lot of test builds, I'm now marking r20 stable.
Please re-read the OP for most up-to-date changes.
Custom ROMs started to rebase their kernel to OxygenOS 12. Those ROMs are not supported, please keep that in mind.

Love this kernel , but without using Naptime , phone just refuses to go to deep sleep
Not sure what happened but I flashed r20 from r12 (via FKM as per instructions) and I am stuck in a weird boot loop. All the phone does is goes from the OnePlus boot animation to a black screen then back to the boot animation and this keeps repeating The phone does not actually reboots by the looks of it (as I don't get the unlock bootloader warning screen). Holding down the power button down to force reboot doesnt work either. At this moment I am just letting it keep looping until the battery fully drains, hopefully I can recover from this.
Seems like slow wifi charging issue is still not fixed on custom roms.
I use latest crDroid 8.6 and wifi charging works fast at the first 10 seconds and then it slows down to ~200 mAh, so it would need around 4h for a full cycle.
Could it be because of the missing USB 2.0 Fast charge feature of this kernel or maybe the kernel recognizes an not existing overheating during wifi charge?

Use the fastboot flash commands for the partitions, with the correct files for that particular software version, then reboot when done. Do not reboot to system until all the partitions have been flashed
So in regards to my issue with the bootloop. I let the battery drain and luckily I was able to get into Fastboot to flash the backed up partitions to revert back to stock. I also found out what was the cause of the bootloop. It was a Magisk module that was doing it, after removing that r20 booted up fine.
New beta release is up: r21b2.
A few minor bugs have been fixed, but the new major change is the removal of BFQ in favor of Samsung's SSG I/O scheduler.
Qualcomm has been using BFQ I/O scheduler for a while now, but its code complexity is quite huge, reaching 10K lines of code.
This unfortunately, translates to more CPU overhead.
With r21b1, BFQ is removed in favor of Samsung's in-house I/O scheduler: SSG.
SSG is simple enough (only 1.1K lines of code) while still having some Android-specific optimizations such as background/foreground separation.
I/O scheduler is a very complicated topic and synthetic benchmarks will not be able to capture the practical effects of one, hence the beta release.
If you notice anything outside of ordinary (e.g., game stuttering, music dropping out, or major lags when updating apps from Google Play compared to r20), please report back.
If all turns out fine, we can expect some battery improvements.
r21b1 had the background profile set incorrectly. Please update.

Somehow with the new build my booting issue with clearLinage Magisk Module (lockscreen was somehow messed up before the first unlock of the phone after a reboot) is fixed for custom roms. Thanks for the release.
now i cant go in my phone it got stuck in the boot logo need help
You got the dtbo flash wrong.... You put "fastboot flash dtbo_a boot.img" It's wrong... the correct one is fastboot flash dtbo_a dtbo.img
fastboot flash dtbo_a dtbo.img
fastboot flash dtbo_b dtbo.img
No "Fastboot flash dtbo_a boot.img / Fastboot flash dtbo_b boot.img "

That was a typo. Corrected.
And flashing boot.img to dtbo won't work anyway due to its size. No space on the partition since boot is larger than dtbo.

Flash once more the DTBO.img to both slots. It was a typo on my side.now i cant go in my phone it got stuck in the boot logo need help
Simply amazing performance overall over here. I'm working twelves while streaming, etc. I'm six hours in, and battery is sitting at 73%. Very thankful to be running this and for the updates.

/* Notice */
OxygenOS 12 is unsupported.
Non-OxygenOS custom ROMs are supported, but your mileage may vary wildly. Most notably, gesture orientations on some ROMs may be inverted.
Custom ROMs that uses OxygenOS 12 kernel, including LineageOS 19.1, are not supported.
This kernel touches vendor_boot and dtbo partitions, meaning you'd need to restore said partitions whenever you're switching to another kernel or stock.
Please make a back-up of these partitions. The installer doesn’t do this automatically for you. Installing the stock ROM with a full OTA restores said partitions as well.
/* Disclaimer */
Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this kernel
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. Hard. A lot.

Kernel source
Telegram chat link19A major new testing release is up.
Changes made in this round is big enough that I've decided to name it r20.
While the build has been stable for me, I'm marking this an alpha as a lot changed.
r20a1 marks the first Linux v5.4 based kernel to have MGLRU backported.
MGLRU is a big deal in everything Linux related, especially for Android.
Esper have a great article on what is MGLRU in a nutshell: https://blog.esper.io/android-dessert-bites-22-linux-memory-management-38419756/
TL;DR:
Personally, I've noticed a sharp decrease in swap usage and improvements in general performance.
Besides MGLRU, there are other numerous patches that are worth noting.
I've brought back updated arm64 routines that were once tried in a beta release but removed later due to random kernel panics (mostly notable from Netflix). The mainline Linux kernel have gotten new updates since then, so r20a1 includes that.
Also, some memory patches made by Sultan are also picked, and I've confirmed that those also help improving responsiveness.
With all these memory stuffs going on, I've also changed swap/zram's parameters. You'll notice a difference in how many apps you can keep open, etc.
The excessive RMNET_DFC wakelock that annoyed some users are now also gone by incorporating a fix from Snapdragon 8 Gen 1.
All in all, this is indeed a pretty big release.
I'm expecting mixed feedback, so please let me know how the new kernel behaves.
