NLOS is an unofficial LineageOS build with many additions. These additions started small and have grown large over the month. So, it's time to name it NLOS - which still is an UNOFFICIAL LineageOS build.
Thanks to @UnbracedTundra NLOS has it's own logo, bootanimation and wallpapers.
LineageOS is a free, community built, aftermarket firmware distribution of Android 8 (Oreo), which is designed to increase performance and reliability over stock Android for your device.
My priorities are stabillity, battery, performance - in that order. This build is optimized for oneplus3t - it will flash and run on a oneplus3, because it's an unified build, but it's optimized for 3t!
In addition this rom contains two patches (https://github.com/microg/android_p...aster/patches/android_frameworks_base-N.patch and https://github.com/microg/android_p...aster/patches/android_frameworks_base-N.patch, ported to Oreo) to be microG ready - this means freedom of choice to flash either gapps or install (microG How to use Android without Google Apps).
NLOS doesn't require any mods to work with @Arnova8G2's GoogleCamera Mod (more details in S4turno's thread ). Just install the modded Gcam - no need to flash twrp-front-fix-oreo-op3-3t.zip, nor to use the magisk module.
The kernel is prepared for Wireguard VPN - to use Wireguard for vpn-tunnels you need to get the WireGuard-apk from playstore. WireGuard developer @zx2c4 runs a dedicated Wireguard Thread.
NLOS features OMS Service Mode - the successor of ThemeInterfacer. This means you don't need root and/or andromeda to have full Substratum Theming! It's faster then andromeda and does not rely on a tethered pc-connection. It has more exposueres (items exposed to the themers) then the rooted solution. If substratum should ask for root previlegs, deny it.
Currently known issue can be found here.
If you find an issue, follow these instructions: https://forum.xda-developers.com/showpost.php?p=58239877&postcount=3
Everybody has his very own definition of "clean flash" or "dirty flash". I use these phrases like descriped in this posting: https://forum.xda-developers.com/showpost.php?p=58239877&postcount=2

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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
This thread is for Unofficial LineageOS 15.1 builds for oneplus3 and onepluy3t. The following will not be supported here:
Custom kernels
Mods
Xposed
gapps packages bigger then opengapps-nano
I don't support Xposed and any logcat which includes a Xposed module will be ignored. You're kindly invited to not report bugs if you:
Flashed a custom kernel
Installed or did mods from untrusted sources
Modified system files (i.e. by using gapps larger then opengapps-nano)
First time flashing NLOS 15.1 on your device, or coming from another ROM:
Backup your current ROM and make sure you have backups of your data you want to keep.
Download the ROM below in the downloads section.
Download current MindTheGapps for arm64. If you insist on using gapps, don't use a package larger then nano.
Download and flash twrp-3.2.3-0!
Download and flash latest OxygenOS Oreo firmware.
Format data: in twrp tap on wipe and then tap on format data. This will delete all data, remove encryption and leave you with ext4, which is highly recommended. If you are insisting to use f2fs see: https://forum.xda-developers.com/on...1-20180223-t3754855/post75688089#post75688089 - NOT recommended!
Wipe system, data and caches.
Flash NLOS.
Flash Google Apps. If you want to use microG skip this step and install microG (How to use Android without Google Apps).
Optional: flash Magisk (if you need root)
Reboot (as usual: first boot takes loooooong )
Updating this rom
Dirty flashing should work just fine: reboot into recovery (if necesarry flash the firmware zip recommended by the release notes) and flash the updated NLOS zip - don't forget to wipe dalvik and cache. Settings, apps and even google apps are preserved.
Important: if you encounter any issues, a clean install is recommended and even required if you need support.
I won't build on a daily (or nightly) basis. I will publish new builds, if I fixed something, important upstream changes or new security patchlevels.

Contributors

Source Code: https://github.com/nvertigo/local_manifest/tree/nlos-15.1
ROM OS Version: 8.x Oreo
ROM Kernel: Linux 3.x
ROM Firmware Required: latest
Based On: LineageOS 15.1
Version Information
Status: Stable
Created 2018-12-04
Last Updated 2018-12-04
Known Issues
fixed: NLOS can't initially encrypt f2fs data partitions (though ext4 is working flawlessly).
fixed: NLOS can't change the encryption passphrase for f2fs/ext4 data partitions (though ext4 is working flawlessly).
fixed: adb and mtp doesn't work out of the box. Workaround:
put in QS-tile "adb over network"
disable wifi
enable "adb over network" with the added tile (tile shows 0.0.0.0)
connect usb cable
an expandable notification shows up
expand it, tap it and select "file transfer": voila.
If you've run through the above adb and mtp are working fine - even trough reboots... automagicaly...
If secure boot password, pin or pattern is set: LiveDisplay's Settings show color profile as "Standrad" after a reboot, though the configuered LiveDisplay's color profile is correctly aplied.
Notification lights have hickups.
fixed: With no substratum themes applied and dark mode enabled the qs edit page is in stealth mode (white text on white background). For reference see: https://forum.xda-developers.com/ap...um-support-t3606400/post76619564#post76619564
Where has "keep wifi on during sleep"?
Sadly this isn't working anymore.
The maker of betterbatterystats offers also a tool to accomblish this task and much more:
betterwifionoff
When switching from lineage-14.1 to lineage-15.1 I found idle bat usage doubled: what has been 0.4 % per hour on nougat increased on oreo to 0.8 to 1.0 % per hour.
On n I've always used "only if charging" for "keep wifi on during sleep", but the access to this setting has been vanished by google. So I exprimented with wifi conf file, kernel driver and wakelock blocking on kernel level. Nothing really solved the adsitional idle drain.
I'm still surprised, what I found while searching settings (cli): the setting "wifi_sleep_policy" is still there! Google has just droped the access via Settings->Network&Internet->Wi-Fi and makes "Always" the default , but the setting is still available and is working like on n.
Value: Function
0: Never
1: only when plugged in
2: Always
To get restore my n setting (keep wifi on while sleep only when plugged in), I only need to connect via adb (I prefer adb over network, but it works as well with usb), and issue this command:
Code:
adb shell settings put global wifi_sleep_policy 1
After spending endless hours on kernel and debugging, this simple command brought back 0.4%/h idle bat usage.
How To: format data with f2fs with current official TWRP
Current twrp (3.2.1-0) can't change the data fs to f2fs. The reason for this breakage is, that twrp expects a mkfs.f2fs command that knows "-r size" as cli-option, but the image is shipped with a version that doesn't know about "-r".
To get data formated as f2fs with space for the encryption footer, you just need to follow these simple steps:
Download attached mkfs-f2fs.zip.
Unzip and place the contained mkfs.f2fs in /sdcard/Download.
Boot to current twrp-3.2.1-0.
In twrp:
Home-Screen->Advanced->Terminal
Code:
cp -vi /sdcard/Download/mkfs.f2fs /tmp
chmod 0755 /tmp/mkfs.f2fs
/tmp/mkfs.f2fs -t 0 -r 16384 /dev/block/bootdevice/by-name/userdata #for the lazy, if on op3/t can use /dev/block/sda15
flash rom (or use the installed rom, which is factory reseted by formating data), reboot t system amd encrypt your device.
The mkfs.f2fs binary is taken from the original twrp-3.2.1-0. This will only work for 64-bit devices:
Code:
file mkfs.f2fs
mkfs.f2fs: ELF 64-bit LSB pie executable ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /sbin/linker64, BuildID[md5/uuid]=46b5f32d88973c91f79744258599a19a, stripped
stuff.

If you're using open gapps just exclude "LSetupWizard" in the gapps-config file.
With the version from 18th February the setup wizard is working, if you are going for a fresh installation.

...if there is an issue, it's either sepolicy or gapps... (devs rule of thumb)
I was so happy, finding a 8.1 package that worked (on beta01 for me)...
It would be great, if we can share gapps info here. Please report which gapps package is working with uri, and which doesn't (uri not mandatory... ).

Most propably: yes.
I don't have my hands on a 3, and I made it my self a rule to only build and push for devices I have my hands on. That's why I stay in 3t forum though it's essentially an unified build. On the other hand: whenever a setting can be tuned for either for sd820 or sd821, I go for sd821. Other then that, NLOS should work on both models, and I try my best to give you support here.
Does the 15.1 version of NLOS have EAS? I vaguely remember the 14.1 version having it...

No.
I've removed it from 14.1 some time ago, because wireguard has triggered some (of perhaps much more) merging errors. After doing some testing (which showed, that plain los was on level with los+eas , regarding speed and bat life [in deed plain los was slightly better on bat life]) I removed (broken-hearted) EAS again.

For people having trouble with gapps try flashing the rom then complete the setup wizard then flash gapps.

OMS Service Mode is still work in progress. Sometimes you need to activate a theme once again after "compile&activate". Some themes (i.e. flux - though it's working flawlessly) refuses to deactivate, but flashing /sdcard/substratum/SubstratumRescue.zip removes all activated overlays. Rebooting is sometimes neccessary. Wiping caches and dalvik may be a good idea, too. SwiftDark and Flux seem to work otherwise.
Special thanx to @danieldmm for helping me out of my brainlock with pointing me to https://substratum.review/ . Without his help I would be still searching for commits currently not meeged... ...that would have taken looooong.... *lol*

EDIT:
HOTFIX:
Set sepolicy temporary to permissive, if you want to deactivate an overlay.
Dirty flashed nlos-15.1 20180226 over 20180225 cause some bugs.
Op3T boots but few seconds after the screen becomes black and the phone reboot to recovery.
Revert to 20180225.
Enhanced TWRP for op3 and op3t
Don't ask these questions. Seriously:
Features: none. It's a recovery. It should be as simple as possible because you rely on this stuff to recover your device in case something goes wrong
Seriously. Were you expecting features from a custom recovery?
Screenshots: it looks like TWRP
This TWRP addresses a number of issues that have been plaguing the op3:
Uses a backported F2FS driver (5.1-rc1-3.18) that fixes an issue where TWRP would get stuck on the TWRP splash screen for a long time if the user was using F2FS
Uses an upstream kernel that was taken from lineage's common kernel https://github.com/LineageOS/android_kernel_qcom_msm8996
Added all crypto footer code back to resolve all encryption issues
Improved detection of device variant. Recovery now validly detects op3 and op3t
A full selinux policy so that files do not get labelled incorrectly. This resolves a bunch of issues like "device doesn't boot after restoring nandroid"
Built against full lineage source. No minimal manifest or any other nonsense
Upstreamed sdfat driver for better suppport for USB-OTG drives
No prebuilt kernels. Uses a fully source built kernel
Ext4 is the default filesystem instead of f2fs
Current issues: even if the source code is out building TWRP against lineage is not something a beginner can do. If somebody is willing to contribute build documentation they are more than welcome

Good work mate keep it up
Great work! Keep it up!
Feature requests
1. Dts Eagle support (audio enhancement)
2. Little gpu over clock (idc about cpu)
3. Charging speed around (1500Ma)which is safe as max pro m1 comes with 1800ma out of the box. (realme has only given 900-1100Ma)
4. DT2W
??
Great work mate.
great work mate. i only request you return the gpu clock to 2.2 as it should be and maybe some oc for cpu as well. thank you. will try asap.
I guess R2pro battery can't sustain overclock of either GPU or CPU from stock values, may be that is why they lowered them

i think it just to preserve more battery thats why they set it to 1.9-2ghz only instead of 2.2ghz. it's nice if we can have option to 2.2ghz though
This kernel is very useful. now red color warning message (ie., rooted mobile) is not coming!!! and we can delete unwanted system apps via es file manager. but we can delete in local drive only. Any way im happy. i hope this kernel maybe work in upcoming stable stock pie rom. Thank you guy.
Thanks for the kernel...The red notification is no longer coming after rooting ..
But LMAO what did u do to the CPU with this kernel??
My antutu score got reduced from 130000 to 85000
Really happy for seeing custom kernel:good:
Hotspots bug is there
Kernel is good. But one major bug is there. That bug is wif hotspot. After flashing kernel and magisk. Mobile is perfectly rooted. red colour warning msg is also stopped and RW is working. very interesting, But first time hotspot is working but after restarting mobile and laptop, the hotspot will not work properly. Laptop shows connected but no internet!!! i cheched stock rom coloros 5.2 ver 14, 15 and 17.

No you can't. Due to ColorOS 6 security, Magisk 19.3 doesn't work fully. Thus, current working version is only 17.1 which has magiskhide as well as module loading.
This kernel is for RMX1801. Don't flash it on RMX1807 or you'll be soft bricked your device.
@redfeast
Thanks! There's one bug in the kernel source - this folder being empty:
/android_kernel_oppo_RMX1801-master/drivers/staging/qcacld-3.0
I removed all references to it and it compiles fine - cheers!
Any chance of porting the drivers over from that kernel (4.4.78) over to the latest one (4.4.193)? The reason being: I cannot enable KVM Virtualization due to a bug in /arch/arm64/kernel/cpu_errata.c that referenced a function named "bp_hardening".
This bug has been fixed in 4.4.193 - but many files have been changed across /arch/arm64/
Kirisakura-Kernel for the One Plus 7 Pro
Hello everyone,
Kirisakura - Kernel is designed to bring a handful of beneficial features to the device, while ensuring excellent performance and smoothness to get you safely through the day!
This project aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security and performance, while keeping stability as the foucs during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.
Kernel Control Flow Integrity (Kernel-CFI), which is achieved by linking the kernel with LLD and Link Time Optimization (LTO), more precisely ThinLTO, are quite unique security features.
The only kernels made by OEMs offering this security feature by default are the ones for the Pixel 3, 4 and 5 devices.
The recently released Kirisakura-Kernel for the OnePlus 8 Pro was featured on the XDA-Portal due to the inclusion of CFI. The featured article explains CFI in great details, is easy to understand and definitely worth to read.
If possible the latest Kirisakura-Kernel releases for various devices aim to include CFI in enforcing mode so users can benefit from this security features.
Another security feature is Shadow Call Stack (SCS). Similar to CFI, only the Pixel 3, 4 and 5 kernels use this security feature.
SCS is another security patchset that is aimed at preventing attacks via return oriented programming (ROP).
ROP is a technique where the attacker gains control of the kernel stack to overwrite function return addresses and redirect execution to carefully selected parts of existing kernel code.
If you´re interested here are a few good links:
Google Security Blog explaining SCS.
LLVM doc about SCS
Android DOCs documenting SCS
If reading about upstream in the paragraph above got you curious,have a read about Linux-Stable and why it is important here. The stable-process is not the same for every subsystem, but the general idea, rule of thumb and benefits are applicable for other subsystems as well.
Quick explanation of CAF-Upstream. CAF is short for Codeaurora-Forums. This is the place where development from Qualcomm for their SoCs happens. This includes the Snapdragon 855/+ that´s built into the different SKUs of the OP7/T/Pro.
The kernel-bases available on the Codeaurora-Forums, are basically the foundations OEMs use, to build their own kernel additions on top for devices featuring Qualcomm SoCs.
The Qualcomm developers push regular updates to the bases of the different SoCs, a bit similar to how Linux-Upstream works. Most OEMs usually stop updating the initial base after the phone is released, and only cherry-pick certain commits to be in line with the android security bulletin.
This kernel focuses amongst the other features to merge CAF-Updates in a regular manner, to provide updates, improvements and enhancements for SoC specific drivers and subsystems! This might take a while, because a lot of device specific testing is done on my end to ensure stability.
The EAS implementation from 4.19 CAF (sd865/+) was ported to this kernel. There are several interesting mechanisms qcom worked on. The basic layout of the soc architecture ( 4xLittle- , 3xBig- and 1x Prime-Core(s)) has not changed from SD855 to SD865. That means instead of revolution there was a very nice evolution the scheduler underwent.
The kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
Many of the improvements originate from @arter97´s, @kdrag0n´s, @RenderBroken´s and @Sultanxda´s work. Many others contributed in some way or another to this kernel.
A big thanks to all of them at this place!

- blocking a kernel wakelock should only be done in case of firmware incompatabilities (WiFi network at work (can´t be changed) causes deep sleep to not work on the phone.) That´s the only use case I see for this feature. The kernel does not features this to improve battery life!
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- magisk root
- be aware kernel is primarily made for OOS, certain custom roms might not boot or have features broken
How to flash the Kernel:
1. Download the latest kernel.zip
1a. Optional: While it may not be necessary all times, you may want to restore stock boot.img, re-root with magisk and optionally install twrp.zip if coming from another kernel. Before reporting issues make sure you do that! Thank you!
1b. Optional: The stock kernel can be restored by either dirty flashing the firmware.zip or by restoring the stock dtbo.img as well as boot.img. Those can be extracted via payload extractor from the firmware.zip.
2. Make sure to use latest Magisk stable.
3. Flash the kernel.zip via latest EXKM or FKM app. Alternatively via TWRP if TWRP is working.
4. Reboot and profit. After flashing the kernel in magisk manager there will be a module called AK3 Helper Module, do not delete it.

Status: Stable
Created 2019-05-26
Last Updated 2020-09-26
Question: Is root preserved when flashing this kernel?
Answer: My kernel.zip keeps a device rooted by magisk rooted.
Question: How do I return back to stock kernel?
Answer: Flash boot.img as well as dtbo.img extracted from the full firmware zip.
Question: My WiFi is not working after flashing the kernel. I can´t toggle it on.
Answer: That means something happened to your device, that is causing some stuff to not get loaded properly when booting. I ran into the same issue once. Read through the thread to find the cause.
I wrote a guide in the linked thread, that explains step by step, how to return to a working condition without the need to wipe the phone completely.
Click the following link to find the post: post is linked here
Question: How to report bugs properly?
Answer: Have a look at post #3 in this thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re not using any mods, magisk modules, scripts or other modifications that alter various functions like sound mods etc.
Try to describe the issue as detailed as possible! Give your exact setup, like rom, magisk version, kernel version.
Is the issue reproducible? Does it happen frequently?
Provide logs, otherwise debugging is a lot harder. If you can already reproduce the issue and provide logs it greatly limits the amount of time I have to spent until I figure out how to reproduce it.
If the device force reboots/randomly reboots (that means you see the bootloader unlocked screen!) provide a ramoops file.
Easiest way is immediately after booting up, with a root explorer navigate to sys/fs/pstore. Copy the contents to your internal storage, zip it up and send it to me.
If the issue happens while the device is running provide a dmesg plus a logcat that you take while/shortly after the issue happens. This will log what´s running in the current session. Try to be as detailed as possible what´s happening when the issue appears. It will also help me in reading the log!
To easily get a logcat in case of a crash take a look at this post:
https://forum.xda-developers.com/showpost.php?p=79462002&postcount=1566
Big thanks to @jcmm11 for it
Here´s a tasker task to automatically copy /sys/fs/pstore on each boot to internal storage. Be advised these files get also created on correct reboots.

thanks @jsauder2 for this little trick

How to report bugs:
It is incredibly useful if bug reports are done in a proper way. That saves everyones time and will ultimately lead to a faster bugfix (hopefully).
The following guide from @nathanchance is a very good guideline on how to properly report a bug!

How to convert your OP7 Pro to use f2fs on /data:
Do this only if you know what you´re doing. This guide works even on stock rom with stock kernel.
OP7 Pros Kernel as well as the fstab support f2fs by default.
If you´re using Kirisakura-Kernel starting with version 1.5.0 you will use the latest upstreamed f2fs implementation. Otherwise you´re running that´s a bit outdated and also a bit slower.
Google did put a lot of work in f2fs and that benefits here greatly too.
1. Backup your data and transfer it to an external storage device, because we will now erase everything on /data
2. Boot to TWRP
3. Go to Wipe - Advanced Wipe - Select "data" - Change file system - f2fs - confirm <- This will erase all userdata including your internal storage (pictures, videos, music etc)
4. Boot up and set up your device freshly.
5. Enjoy f2fs on your OP7 Pro

Well, I wasn't planning on unlocking the bootloader in this phone.... Going to now that you're here! Thanks for your hard work
Dude,
So pumped to have you on the OP7Pro! This is shaping up to be a really well supported device!
Sent from my OnePlus7Pro using XDA Labs
So hey everyone
want to lose a few more words here. I spent quite a bit of time getting this up as quickly as possible. I never had an OP device until now. So I needed to get familiar with it and get the hang of it.
I spent quite some hours and most of my free time since thursday, in the hope of getting this up before the weekend ends. Some people I spent less time with, were not quite as happy about this decision, but so be it.
I had quite a bit of experience with the CAF merge from the Pixel 3 XL, that made things a bit more easier and smooth. Upstreaming to latest linux-stable was quite a pain, because there are several commits, which cause the device to boot straight into Qualcomm Crash Dump mode.
In the end I got to 4.14.122
It´s still early here on this forums. So far now use adb sideload to install the kernel. The magisk module needs to be flashed otherwise some things, like accessing battery settings isn´t working, because of selinux-denials. If you can live without it, I´m pretty sure you can run this kernel also unrooted. But for the things I mentioned magisk is required, because you need to flash the companion module.
Once TWRP data decryption works, we can flash the zip simply in TWRP. Once EXKM and FKM are updated, we should be able to flash the zip via the apps too
For now it´s this way
I have a few more plans for this kernel, like wireguard, adding maybe some (not to much) features to it, maybe use f2fs and bringing it to latest state. I´m pretty sure I find more stuff as well.
The kernel is way more snappy than the stock kernel for me. It uses some of the EAS improvements from my Pixel 3/XL kernel, which can be utilized on this newer kernel base as well.
I confirmed it with a few little tests/benchmarks and for me the difference is night and day.
I´m running the device always full resolution and 90fps
If somebody can confirm, this it would be really great
If you encounter bugs, please take a look at post #2 and #3
there is a bit more in the kernel than the pure OP. I´ll update it the next few days
I wish everybody a nice weekend.
Great to see you here on this device!
Welcome to the world of OnePlus! This is my second device from Oneplus and finding it an awesome device. Sad to see HTC go down the tubes.
great to see you here freak!
Great news. Just flashed all working well so far
Great to see you here freak & we all appreciate you giving up your time. I'm staying stock until Stable Twrp is released, but as soon as it is I'll be using your kernel.....
@Freak07,
Never thought there would be a day that we would both be on the same device again.. ( I technically haven't gotten the device yet.. waiting till next month),
But glad you are here man. Your work is awesome... Now I got someone to cherry pick from JK man.............
BTW< stop by Slack every once in a while man.
Looks promising, I'll flash it! Good job!
hey bud message me on telegram guess we meet again lol im working on my stuff now glad to see you here @Freak07 and eleminator
Wow it's so nice to see you here! Never thought I'd see the day haha

Hey buddy,
I would love to see WireGuard support as I use it all the time. I much prefer the kernel implementation as it doesn't consume any battery compared to the userspace version which does.
In terms of F2FS are you also going to update in line with how Arter97 does things and also implement his Rapid GC commit and subsequent changes?

- s2idle-flow improvements from mainline
- improve efficiency while music playback
- arm64: lse: Prefetch operands to speed up atomic operations
- improve camera launch time
File System related features:
- Include latest f2fs changes found on f2fs stable git
- Include rapid GC by @arter97 ( best thing is to read the commit description linked here. I compared GC on stock google f2fs, upstreamed f2fs and f2fs with rapid GC. Rapid GC is the most effective, followed by upstreamed f2fs.)
GPU related features:
- KCAL to control various RGB related display configs (RGB, Hue, Saturation etc -> accessible via CleanSlate Config App)
- add ability to reduce minimum brightness
- add high-brightness-mode (HBM)
- Update GPU driver to latest CAF state
- improve GPU performance (overall smoother experience)
- reduce power consumption when rendering static images
- enable of usage of SD855+ GPU frequencies as optional feature
UI/UX/Usability related features from CleanSlate:
- CleanSlate features made by @tbalden
- Adjust all CleanSlate features with the CleanSlate-Apps found in the CleanSlate-Thread (if you profit from the CleanSlate features make sure to buy the premium versions on Play-Store to support
@tbalden
- CleanSlate options that require permissive selinux in any way are not included, as they can be easily achieved otherwise on a rooted environment and this kernel is not intended to be used rootless (adblocking, props spoofing etc.)
- Flashlight Notification/Call blinking
- Vibrating Notification Reminder
- Sweep to Sleep touchscreen gesture - highly customizable
- DoubleTap on Sweep2Sleep's area gestures - new way to pull down android Notification Area
- Face down screen off - new gesture, e.g. conveniently use together with 'flip to shh' to turn screen off

- Wireguard Support (Details)
Memory related features:
- updated PSI monitor with latest changes
- improved mm with patches from latest mainline
- various other changes from mainline
- included zstd and lz0-rle as options for ZRAM-algorithm (lz4 is probably the best all around, so only change it if you know why and what you are doing)
- allow swappiness up to a value of 200
- Backport to enable CONFIG_HAVE_MOVE_PMD (see here)
- Backport to enable CONFIG_HAVE_MOVE_PUD (see here) (reverted for now as it breaks audio driver)
- improvements to ZRAM writeback (thanks @arter97 )
- disable per cgroup tracking via psi to reduce overhead
Security related features:
- CFI and LTO both kept intact and are used to keep additional security Google implemented for us!

How to flash the Kernel:
1. Download the kernel.zip to your device
1a. While it may not be necessary all times when coming from another custom kernel: You may want to restore stock boot.img as well as stock dtbo.img, which can both be found in the factory image. If you´re on a custom rom, simply dirty flash your ROM. Reroot with magisk and optionally install twrp.zip (if existing). Before reporting issues make sure you do that! Thank you!
1b. If you used the SQLITE3 Magisk Module and the GPay Fix Magisk Module in the past look at this post: click me
You only need to do either 2a OR 2b
2a. If TWRP is available for this device and specific android version, boot to TWRP and flash my kernel.zip. Root will be preserved!
or
2b. Flash kernel zip in EX Kernel Manager or FKM app. Root will be preserved! If a kernel manager is not yet updated to work on a specific Android Version, you need to wait until it is updated or use another one.
4. Reboot and profit!

Version Information
Status: Stable
Created 2019-10-27
Last Updated 2020-11-03
F.A.Q:
Question: Is root preserved when flashing this kernel?
Answer: Yes the Anykernel Zip will detect root and keep it.
Question: How do I return back to stock or another kernel.
Answer: Extract boot.img and dtbo.img from the factory image and flash them via fastboot.
Question: How to report bugs properly?
Answer: Have a look at post #3 in this thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re not using any mods, magisk modules, scripts or other modifications that alter various functions like sound mods, data traffic etc.
Try to describe the issue as detailed as possible! Give your exact setup, like rom, magisk version, kernel version.
Is the issue reproducible? Does it happen frequently?
Provide logs, otherwise debugging is a lot harder. If you can already reproduce the issue and provide logs it greatly limits the amount of time I have to spent until I figure out how to reproduce it.
If the device force reboots/randomly reboots (that means you see the bootloader unlocked screen!) provide a ramoops file.
Easiest way is immediately after booting up, with a root explorer navigate to sys/fs/pstore. Copy the contents to your internal storage, zip it up and send it to me.
If the issue happens while the device is running provide a dmesg plus a logcat that you take while/shortly after the issue happens. This will log what´s running in the current session. Try to be as detailed as possible what´s happening when the issue appears. It will also help me in reading the log!
Useful Resources
How to report bugs:
It is incredibly useful if bug reports are done in a proper way. That saves everyones time and will ultimately lead to a faster bugfix (hopefully).
The following guide from @nathanchance is a very good guideline on how to properly report a bug!
https://github.com/nathanchance/Android-Tools/blob/master/Guides/Proper_Bug_Reporting.txt
SQLite3 and GPay Fix Magisk Module:
The combination of these two modules and F2FS-Upstream patches included in the 1.0.x release kernels, caused the device to freeze sporadically after rebooting.
2.0.0 does not include F2FS-Upstream so these two modules can be used again.
To remove the modifications done by these modules and start clean again on Release 2.0.0 and the following releases do the following:
1. Remove the SQLite 3 Module and the GPay Fix Magisk Module by following instructions
2. Do a full reboot
3. Wait a few minutes after successfully booting
4. Clear data and cache for Google Play Services, Google Play Store and Google Pay
5. Wait a few minutes so all deleted stuff gets rebuilt properly and reboot again
6. I´d prefer to use the following method to enable GPAY functionality instead of the modules: https://forum.xda-developers.com/showpost.php?p=80763371&postcount=11
7. If you really have to, install both modules and make sure you´re on Kirisakura 2.0.0 or greater
Oh snap! The fun has begun boys! Good to see your kernel here!
Glad to see dev progress so quickly. Will check this out. Kudos
That was awfully quick! So glad to see you here.
Thank you @Freak07. Flashed without a problem with EX KM. Nice work.
That was quick! Thank you so much. :good:
I am unbelievably excited to see you here! I'm glad to see an amazing DEV working so hard, and quick, to bring an amazing kernel to the 4xl!
So very happy @Freak07 maintaining a kernel for the OP7/7pro and now the P4/P4XL. Thanks for all you do man!!
Anyone has an alternate download link? Because androidfilehost is extremely slow and terminate the connection after about 15-30 minutes
You got the 4 XL, awesome! Happy to see you here
Getting my 4 XL tomorrow, will be flashing this as soon as it's delivered
Ok the download worked finally. Such a crap, had a lot of similar problems with this lousy hoster in the past
Dies anyone know If it is possible to get 4k at 60 fps? On other Smartphones it was possible in the past but i don't know if it will be possible with our Pixel 4.
any big difference between exkm and fkm?
glad to see you here...
PS: Ignore my PM lol
Good to go!

Nice! Flashed with EXKM or FKM? Or good old fashioned fastboot flash boot?
Edit: Flashed with FKM and no issues with flashing.
I do notice that charge speed is about 1500mA slower than with stock kernel. Although I do remember with my Pixel 2 XL similar behavior occurred with a slower reported mA, but overall charge time was basically the same as stock kernel.
Edit 2: And of course I jumped the gun. Just checked again and charging is back to stock speed, approximately 3200mA.

For flashing no. Both flash the same way.
I Feel compelled to remind people dont ask for features or ETA's especially the day a kernel gets released. I already see that in the first page.
That being said:
The developer here wants feedback about how the kernel works on the device not a bunch of off topic comments /questions this is a development forum.
We do have a q/a and general section for this device feel free to create a proper thread.
