Reserved post is for screen shots I gotta upload them still sorry been busy will try to get them up later today also adwlauncher is removed automaticly if you choose launcher pro during install.

am i right in thinking this is an ultra lightweight ROM? it certainly seems to be, based off your feature list.
i'm wondering if this could be a replacement for the Oxygen series...

Well first thanks for considering the rom and I would recommend a full wipe but u might be ok to just wipe cache and flash also try the alpha kernel I have tweaked 3d and quadrant is showing a good boost on my desire the kernel is stable but compcach is not working yet and if u flash a kernel be sure to wipe your battery status and also if you could send me a private message and tell me what u would like to see done with the camera I would appreciate it

weeei, new dev and new rom... welcome and thank you for sharing,
as a flash maniac...downloading and i will install asap.
my only question: does mp4 HD videos are working? i will flash it anyway... but just curios
---------- Post added at 11:27 AM ---------- Previous post was at 10:44 AM ----------
does this work on 4ext recovery?
it looks like it doesn't finish installing...
EDIT:
ok, i found the problem is here: "-Answer when promted". it's not made it for 4ext (doesn't contain 4ext syntax)...hmm... i recover my bk...until an update

Known Issues (regarding latest available Stable build)
Please do not report bugs if it is already listen in the list of known issues
Rarely, when you wake-up the device, touchscreen will have a noticeable input lag, easily fixable by turning off and on the display. (H/W or S/W bug?)
Wireless Display with some TVs could cause issues (AOSP bug related to HDCP, and Google doesn't provide a solution)
Video Stream through Screencast & Wireless Display will have inverted Red and Blue color channels due to BGR Pixel Format (actual Exynos sources don't allow to fix it)
Any Chinese (CHN, I9500XCUxxx codename) Baseband/Modem reduces Call Quality (due to forced AMR_WB, unsupported by CHN modems)
5GHz Wi-Fi Networks using Band B (52-140) and Band C (149-161) channels won't be listed (H/W or S/W bug?)
Reporting Bugs
You are allowed to report bugs only in this thread. Before reporting a bug, please make sure you are running as stock as possible. This means no custom kernel, no custom framework modification, etc. If you are using any of the above modifications, please flash the rom again to get rid of the modifications before reporting.
REPORT BUGS IN THIS THREAD ONLY
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. The following is a useful format to follow. Note: If you can provide the latest night/build that the bug didn't exist, it would greatly help in tracking down what caused it.

Read carefully.
Differences between GearCM (Optimized CyanogenMod) and Official CyanogenMod (NIGHTLY):​
Degrated Shadow said:
Enough of those dumb questions..
The official CM rom is maintained by @Alberto96 and @intervigil
He makes the very recent changes here relating to performance.. which are then in time pushed to CM official rom. The kernel is different because it has selinux disabled and few minor tweaks you might not even notice.. this gearcm rom will have more performance. But CM rom will have their updated base changes which are included here with each update.
What I mean is you probably wont even notice what's different in terms of user interface.. gearcm will have more performance. Official cm will have updated sources. But it will include gearcm's changes in time as @Alberto96 pushes them to CM
You can decide by a simple choice. more performance and not-nightly updated sources or similar performance (improving with nightly updates) with updated sources. I would choose gearcm because of the reasons I mentioned above. Do what you will.. and let this be a note to everybody who ask this again and again and again. Don't spam the thread with same question in every alternate page.. Because there are other people who might have different problems they need to ask. Read atleast 15 previous pages and the first post changelog before asking the question. Reading most of the times will give you a solution and if not most of the info you will read will help you anyway.

FAQ (Frequently asked questions)​
Where are "Performance" and "Developer Options" categories?
To activate 'Performance' and 'Developer Options' categories in Settings you need to tap 7 times on 'Build number' located into Settings -> About Phone.
How can i solve problems with Hebrew language?
Go to "Developer Options" in Settings and check "Force RTL layout direction".
What can i do to reduce the "echo effect" while in-call?
Try to reduce in-call earpiece volume (if possible).
I'm having problems with battery life, what can i do?
1) Use "Greenify" to hibernate all apps with a "little cloud + 'Gcm' word inside" on the right of each app's name. Donation version is recommended because it allows deeper hibernation of apps
2) Disable "Location" or set it to mode "Battery Saving" (Settings -> Location)
3) Make sure that your 2G/3G mobile network signal level isn't always low or unstable
4) Deny "Wake Up" and "Keep Awake" permissions to Google and third-party apps. (Settings -> Privacy -> Privacy Guard -> Press menu button and check "Show built-in apps" -> Press menu button again and go to Advanced -> Horizontal Scroll to Device)
5) Disable "Sync" or sync only useful stuff like Contacts
6) Disable "Auto-rotate screen" (Settings -> Display & lights -> Rotation)
7) Use one of the latest Modem/Baseband listed on first post.
8) Disable Ambient Display
9) Install Xposed Framework and configure Amplify
If this isn't enough then replace your battery and/or reduce your phone usage. :silly:
Is GearCM OTA supported?
Yes (Since 20150707 Build)
Why is my phone over-heating while playing heavy-games or running heavy-apps?
Use a bit your brain to explain why. High CPU and GPU usage = high heat production. Your phone will automatically throttle CPU when needed so don't worry, it is safe and normal.
Can I use another kernel instead of the one included in the zip?
No. Only use the included kernel for 100% compatibility, bug reports with non-standard kernel will be ignored.
Can i disable S-View cover features (lock/unlock)?
Not yet.
*** IR Remote app isn't working anymore/was working on previous builds/causes my phone to crash, what can i do?
Contact *** IR Remote app developer.
Any question about "Can't connect to camera" issue
Do not "stress" camera on CM because we don't use yet a proper implementation. Open/Close Camera apps carefully without force-closing them.

fix stock camera try flash this zip https://www.dropbox.com/s/z2a7hegwzu9ft2c/Fix_Camera_Cmmct_5.0.zip?dl=0

Been using lollipop as a daily driver with awesome results. But still there's something that bugs me. Although GPS works fine I find that its accuracy is pretty low.
For instance I run in order to keep fit. I use adidas miCoach which calculates your speed and distance covered giving as result km speed (from Argentina). GPS has a hard time keeping up with this and every time I train I revert to TW and then back to Lollipop.
Will test this GPS and see if its better than team Cajinica

does this rom have working bluetooth calls over car stereo?

Great. Downloading now[emoji1]

"App not installed" if manually install an apk.
Is there any workaround?

@Alberto96 haven't test it on GearCM 11. I'll try and report back asap

Can't install apks.
Although pushing apks to system works. Titanium backup in not able to restore as well.
Edit: I guess Titanium Backup does work. Not with the default superuser though. I flashed supersu to get it working in frapeti's rom, strange.

With GearCM 11 latest build GPS is pretty accurate. Used Waze while driving and miCoach while walking and had good results.
Further testing done with the build posted (20141216) I can't access SD card to install apks that are not from playstore for example BBS, and getting the low memory message even if full wiped and fresh installed.

Can't install APK in this Build ...

Storage Issues
@Alberto96 Hey man there seems to be an issue with your Kernel please take a look at the changes u made as they seem to be the cause of peope not being able to install any APKS and Install from playstore as its complaining about the storage being low so what i did is compile with CM kernel and tested it and the GearCm works fine without any storage issues but if I compile it using ur GearCm Kernel thats where theres storage issues. Please take a look at it

Thanks for your time and dedication of this Alberto. Unfortunately I'm having a hard time with your CM12 Releases
With CM12-20141212v2 (I did a clear wipe) and no RIL Service. So I was not able to use it basically...
Today I gave it a second try CM12-20141216 . I was happy to see my 3G Connection. But when I started to download the app from Play Store. It was impossible. All APKS giving an error.
I will test Canjica Version. It's a pity but I will have to wait till we get to a stable version of Android 5.0.1 with GearCM12.
Despite of that, Thanks for your work on this! We wouldn't have this if it wasn't because of you

Heads Up
Brilliant to have 5.0 on our phones, look and feel is really cool.
Confirmed Working:
Calls, SMS, Internet (WIFI & 3G), Camera, Gallery
FC's:
Music, File manager, Play store (all google apps) & anything else which is on the SD card
Keep it up guys:good:

Application not installed?

thanks for update 12\21 @Alberto96 ...but issue with installing apk is here.

New build is coming with some fixed, especially performance related.

New build is up!
Enjoy

What is AOSP?
AOSP is Android as Google publish without other modifications. More or less AOSP is the Nexus devices stock rom without gapps. Anyway to get a working system me and @-+BB+- added some changes from CyanogenMod. We added also some non-AOSP features like init.d support, @alucard_24 kernel for better performance and energy saving, STweaks for advanced kernel settings and support for Over-The-Air updates through a dedicated app (OTA Updates). Maybe something else from us might be added, but please do not ask for features to be added because we're not going to add more to keep this ROM small, fast and pure.

Tips
To enable Developer options go in Settings->About device and press "Build number" for 7 consecutive times.
Using F2FS
What it is? Wikipedia
To use it you should first convert your EXT4 partitions through recovery, before installing this ROM.
On PhilZ:
Wipe and format options->custom format options->toggle ext4 f2fs migration
Format data and data/media->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)
Format system->f2fs
On TWRP:
Download and install this TWRP version: https://www.androidfilehost.com/?fid=24052804347763625
Wipe->advanced wipe
Select data->change or repair file system->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)
Select cache->change or repair file system->f2fs
Select system->change or repair file system->f2fs
Now you can install this ROM following installation steps in post above

Some screenshots

We mainly talk in the i9505 thread located here, head over for further details about development progress, bug fixing etc.

I'm curious why the OP doesn't mention the 5MB email attachment limit? how was this not tested?

Help

[Kernel][21.08.2021][4.14.243][Android 11] Kirisakura 1.3.9_R for OP7/Pro aka Guacamole

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:

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.

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?

[Kernel][28.05.2023][4.14.315][A12][A13] Kirisakura 9.1.6 for Pixel 4/XL aka FLORAL

Kirisakura-Kernel for the Pixel 4 and Pixel 4 XL
Hello everyone,
After rising to the most popular kernel on the Pixel 3/XL forums, here is Kirisakura-Kernel for the Pixel 4 (FLAME) and Pixel 4 XL (CORAL), together FLORAL.
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!
The kernel aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security, stability and performance!
This includes Linux-Stable, CAF-Upstream, F2FS-Mainline and kernel/common.
If that 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.
Main Features:
- Based on latest kernel sources from Google, Kernel is made for Android 13
- Linux-Stable-Upstream included to latest 4.14.315
- CAF-Upstream usually based on one of the latest tags for sm8150
- include all important fixes/improvements from kernel/common
- compiled with latest Clang 16.0.2 from Google prebuilts and built with -O3 optimizations
- F2FS implementation updated to latest state of kernel/common and kernel.org maintained by Jaegeuk Kim.
- devfreq backports from 5.4 (sd 888 qcom kernel base)
- Safety Net patches are included -> Kernel passes Safety Net (hardware attestation is not related to these kernel patches)
- Flashing the kernel will keep root!
- Tested to work on custom ROMs
- Flashable via EXKM and FKM on a rooted system!
- remove extensive Memory Management logging from Google
- removed nolog usage, remove rtb logging from the kernel
- remove selinux auditing from kernel for lower overhead

- 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)

- 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

Other features:
- disable logging to make the kernel more lightweight in various places (includes mm, vma, gpu, ipa etc)
- remove VLAs from the kernel (more info)
- add support for steam controller
- add support for nintendo switch controller
- merge upstream solution for PM/Wakeup driver, which reduces unnecessary logspam and also improves sleeping behaviour
- merge freezer v2 backport from google gerrit (required for developer option ""suspend execution for cached apps"")
Feature section for the "non visible" but perceptible improvements:
- updated binder section (responsible for interprocess communication)
- updated sdcardfs ; have a read about it here:
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- working magisk environment
- latest stock rom (custom roms can have issue, several users reported success when rooted with magisk 24.3 instead of latest)
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!

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.
