Sorry for the inconvenience, I have a Rogphone 5 16/256 with Bootloader unlocked only, I have read the instructions but I have not understood some things well: I have the stock firmware with Bootloader unlocked, I just need to install the twrp, root and kernel and enough? Do you need to do some wipes? Thank you so much to those who will help me.

if you already own ex kernel manager or franco kernel manager app, you can use those to flash the kernel.zip. then there´s no need for installing twrp.

you don´t need to do any wipes. just follow the instructions in the first post.
make sure your phone is rooted, before flashing the kernel.

thank you very much x the answer I appreciate it very much, it is very noticeable that you are a dev. very attentive to our needs and quick in lending a hand to the end user, one last thing but this kernel was also born to set up and improve Rogphone 5 in the various aspects where a kernel can intervene?

Read the first post for features and aspects of the kernel. It's pretty detailed already.
There are a lot of links and for the rest Google is your friend.

Installed it one hour ago and "lost" the ability to control my rear touches with my Ultimate. At least my rear display still works. The option to set/change/enable them completely disappeared everywhere.
Is there a way to enable it for you without having the device? For now I could live without it but it would be cool to use them again in some time.

Unfortunately as already said no real change in Bluetooth audio game latency but the phone is generally a little bit hotter. At least it never went above 35°C before in the games I play mostly, not it reaches that level after a few minutes and surpasses it. 😅

However it feels a little bit more smooth 😎👍

might just be something else in the background. temps are about the same for me.

oh no, I was afraid of something like that. you´re rooted like in requirements mentioned?
can you go to terminal, type "su", grant permission, then when the beginning is a "#" type "lsmod" and paste the output here?

unfortunately I really lack the time at the moment to do longer remote debugging sessions. if you know how to take logs, logcat and dmesg, play with the rear zones on stock kernel and see if you see some lines when enabling, disabling the zones. That might be helpful. Then upload the logs here and point me to those lines.

You were totally right about the temperature.. It went down to normal now.

Yes I had/have root access before and now.

Code:
$ su
:/data/data/com.termux/files/home # lsmod
Module                  Size  Used by
:/data/data/com.termux/files/home #
I'll see what I can do about the logs. Never did that. I'll play around when I have time and come back.

Is there any particular order in which I have to flash boot.img, vendor_boot.img and dtbo.img

Did you flash TWRP?

Can you run those two commands before flashing stock kernel and trying to get logs? They need su access.
insmod/vendor/lib/modules/focaltech_fts_rog2.ko

insmod /vendor/lib/modules/sx932x_2nd.ko

Afterwards try lsmod again and see if they are loaded. Maybe check for the touch sensitive zones again.

Reinstall the kernel zip from the system side and it will fix itself.

I didn't Flash twrp - I'm still a bit unsure what to do in which order to keep root + kernel + twrp 😅

Until I'm 100% sure I'll boot into it via fastboot each time.

I'll try that in the next ~12 hours (it's night time for me now) I read about how to take those logs and I'm sure I can provide all the required information now.

The only thing I need to know is where to get the original kernel from.
Not sure if I need to unzip my WW firmware from the Asus site and just copy those files or if I need to follow the instructions from https://forum.xda-developers.com/t/vendor_-boot-images-root-stock.4325939/

Have a copy of Magisk apk, the kernel zip from this thread, and the twrp image on your sdcard.
Boot TWRP and do Advanced -> Flash current TWRP
Install Magisk through TWRP
Reboot to system
Install the kernel zip

You'll have all three installed and running

Deleted... Typed too slow. Your answer was already there


hey, I just discovered that flashing the kernel.zip via TWRP is not working correctly at the moment.
The helper magisk module that´s supposed to replace two of the kernel modules is not getting installed correctly if TWRP is used.

Do you own EXKM or FKM app? If so can you please try flashing the kernel.zip via either of those apps?

If not I create you a separate zip, that should make it work in TWRP.

I don't own them but I could buy the cheaper one if that saves you some work. But I still don't know where the stock kernel.zip is. Is it the kernel-source.tar.gz file from here https://www.asus.com/supportonly/ROG Phone 5 (ZS673KS)/HelpDesk_Download/ below the source code region?

there is no stock kernel.zip.
you need to extract boot.img, vendor_boot.img and dtbo.img from the payload.bin inside the full firmware zip available on asus support site.
Flash all those three .imgs via fastboot and you´re back to stock. If you want to stay rooted patch boot.img via magisk-manager prior to flashing it via fastboot.
You can extract them with this tool for example:


attached is a more recent build of the kernel alongside a magisk module.

To try them, boot to TWRP, first flash the kernel.zip and directly afterwards the DLKM zip. Reboot.
After reboot go to terminal and do the lsmod command again and show me the output please :)

I do that for every firmware, along with posting the magisk patched boot images. The DTBO has never need to be reverted, but I can throw that in the ones posted and start including it.

I know, I saw your thread and it's nice that you do this.
But I think it's also important that users learn to do that by themselves if needed. Especially if they choose to modify their phones, they should know how to revert it without too much help from outside. And it's mentioned in my OP :)

My kernel flashes a modified dtbo.img, so the three images I mentioned need to be restored if one wants to go back to stock completely.
So I think people would appreciate if you start adding dtbo.img to your thread too :)

    Big update for .196 firmware dropping soon.

    About stability for the previous versions here's a screenshot. Over 30 days without rebooting the phone and a single crash.
    Those that suffered from them, remove all magisk modules, don't disable any system apps, don't remove them or do other mods. Pretty sure problems are caused by this.

    On zf8 (which shares a lot of the codebase) there were a few users that also crashed to ramdump or otherwise and all of those were caused by using either mods or what I described above while running my kernel.

    Kirisakura-Kernel for the ROG Phone 5

    Hello everyone,

    To keep it short: Here is Kirisakura - Kernel for the Asus ROG Phone 5 aka Anakin. The ROG Phone line-up internal codenames are traditionally derived from Yedi-Characters of the Star Wars universe. Three years ago the 1st gen ROG Phone bore the generic title "Yedi", the ROG Phone 2 was codenamed "Yoda" and the Rog Phone 3 bore the title "Obiwan".
    I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.

    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!
    If you expect a custom kernel to magically improve your devices battery life manifold and this is your only priority then this might not be the right place for you.
    However the kernel is built to keep battery life close to the same as you would experience the on stock kernel while being tuned to perform better in various UI related benchmarks. The same benches are used by google to verify and ensure UI smoothness on the Pixel devices. The scheduler is tuned to yield lower jitter and reduce jank frames.
    There´s also a cpu-battery saver mode that cuts back the CPU max- freqs, but without the disadvantages like delayed notifications from built into the system user-space power-saving modes.
    If that got your curious, I welcome you to continue reading if you´re still interested!


    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.


    A very positive development. Google pushed for CFI and SCS to be enabled by default in the android-common kernel. In this years generation ( 5.4 linux kernel base/ SD 888 ) CFI and SCS are enabled by default. It was a lot of work to get these features working nicely on the kernels I did develop on for the past few year. So it´s nice to see this is now there by default in everybody can profit from it.
    I put the explanations and links in hide tags here.

    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 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).
    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 linux or caf/qcom 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.
    Read more about the Release-Model following this link.
    This conversation on the LKML mailing list also shows the power of Linux-Stable and why it´s very beneficial to not just say it´s not worth and a potentiol source for bugs:
    Starting with the Initial Message , the following reply and a good summarizing statement.


    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 888 that´s built into the different SKUs of the ROG Phone 5.
    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. OEMs usually stop updating the initial base after the phone is released.
    This kernel focuses amongst the other features to provide the latest CAF-Updates merged 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 kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
    A big part of improvements originate from @arter97´s, @kdrag0n´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!

    Now lets continue with a list of features in the next paragraph!


    Main Features:
    - Based on latest kernel sources from Asus for Android 11 and intended to be used on the latest Asus Stock-Firmware (currently 18.0840.2111.166)
    - compiled with Clang 13.0.1 and built with -O3 speed optimizations
    - Linux-Stable-Upstream included to 5.4.161
    - upstreamed CAF base for the Snapdragon 888 (qcoms internal codename "lahaina")
    - include important fixes/improvements from kernel/common
    - tune scheduler for improved jitter and less jank frames
    - reduce power consumption during deep sleep
    - remove logging while device is suspended
    - remove sleep debugging from Asus for release build
    - disable various debugging mechanisms for drivers which are not needed on a perf build (for example touchscreen, fingerprint reader, display, binder)
    - disable various debugging configs, that are not needed in a perf kernel build according to google.
    - disable selinux auditing (we don´t have to adress selinux denials running a stock rom)
    - display tweaks to reduce power consumption on statically rendered images
    - disable unnecessary CPU errata for our specific SoC
    - disable per cgroup pressure tracking to reduce overhead
    - free up RAM by removing reserved mem regions used only for debugging
    - implement LRNG (thanks @arter97, see arter kernel OP for more info )
    - Flashing the kernel will keep root!
    - Flashable via EXKM, FKM or TWRP (if available) on a rooted system!
    - Anykernel zip is based on the Anykernel3 release from @osm0sis


    EAS related features:
    - Implement dynamic WALT-Window size depending on current FPS, collecting information about CPU-Load to provide more precise information for the scheduler
    - EAS implementation patched up to latest CAF state
    - updates from kernel/common
    - scheduler updates from sd888/ 5.4 kernel
    - scheduler update from sony xperia 1 III kernel aiming to improve WALT

    CPU related features:
    - Power saving workingqueues enabled by default (toggleable in EXKM)
    - Change various drivers (WLAN, MM, audio, charger, power, thermal, glink etc) to use power efficient workingqueues. This compliments EAS in general

    - vdso32 patches as found on Google Pixel devices (brief documentation here) (CAF 5.4 default, keep for documentation)
    - remove event debug logging
    - disable broken irq detection, disable debugmon
    - improve suspend/resume from audio driver (caf-upstream for audio-kernel)

    - disable debugging during sleep states as per qcom recommendation
    - remove RTB logging to reduce overhead
    - disable trace_printk as it shouldn´t be used on production/perf kernel builds
    - disable edac and coresight (following google on the pixel kernels)
    - disable jtagv8 debugging as recommended by qcom for perf builds to avoid potential power, performance and memory penalty
    - disable s2idle in favor of deep idle state -> improves deep sleep drain (google initially used 2idle for improved suspend/resume latency on pixel 3 and pixel 4, but disabled it on pixel 5. qcom followed suit for sd 888, but apparently didn´t see google reverting it on pixel 5. Other OEMs such as Xiaomi or OnePlus already disabled s2idle on their SD888 devices in favor of deep- read more about s2idle vs deep here)
    - raise LTO-inlining -> more info

    GPU related features:
    - GPU driver updated to latest CAF-State

    - improvements to deep sleep power consumption (ufs driver, auto hibernate)

    Audio related features:
    - provide option to override audio profile based on impedance measurement (run 16ohm headphones in 64ohm mode, dangerous use with caution!)
    ----> more information/explanation how to control the feature linked here

    Display related features:
    - Backlight Dimmer (reduce minimal brightness below stock limit)

    - Shadow Call Stack (SCS) Security-Feature ( 5.4 default, keep for documentation)
    - enable init_on_alloc for even more security, more information can be found in the commit message (CAF 5.4 default, keep for documentation)


    Misc Features:

    Wakelock Blocker:
    - advanced wakelock blocker with the ability to block any wakelocks (dangerous, use with caution)
    - please read [URL="https://arstechnica.com/gadgets/2018/08/p-is-for-power-how-google-tests-tracks-and-improves-android-battery-life/"]this for further info
    - 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!

    Other features:
    - clean up asus drivers and fix a few warnings in kernel log
    - disable logging and debugging to make the kernel more lightweight in various places (includes binder, mm, vma, gpu, ipa etc)
    - fix several coding issues detected by newer Clang-Toolchains
    - enlarge dmesg size to ease debugging


    Flashing Guide, Download and Changelog

    Requirements:
    - unlocked Bootloader (this will void warranty and kill future OTA updates on all asus phones at the moment)
    - USB-Debugging in developer options enabled
    - latest adb and fastboot binaries
    - working adb and fastboot environment
    - magisk root
    - a backup of stock boot.img, vendor_boot.img and dtbo.img so you can go back to stock conditions (simplest way is TWRP or to extract from stock firmware)

    How to flash the Kernel:
    1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Asus Stock-Firmware (check the feature list for the current firmware the source is based on). When the ROG Phone 5 receives an OTA update it takes Asus a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
    Always make sure to run the firmware the kernel is built for!
    If you feel adventurous and try in advance, make sure you have a backup ready!

    2. Flash the kernel.zip via latest TWRP (if available), EXKM or FKM app and do a full reboot.
    2a. Important: If flashing the kernel via TWRP, flash the DLKM magisk module found in the download folder that matches the kernel version.

    3. Reboot and profit.


    DOWNLOAD:
    Download is located always in this folder:

    Important: Read after Download
    Please take a look at the second post after flashing the kernel!

    F.A.Q:

    Question:
    Is root preserved when flashing this kernel?
    Answer: Yes, the AnyKernel.zip will detect root and keep it.

    Question: Safetynet does not pass on my phone since I unlocked the phone, why is this so?
    Answer: Google introduced hardware backed attestation recently. Unfortunately the old kernel tricks to still get safetynet passing won´t work. Instead you will have to rely on some magisk modules. Short guide in post #4 below.

    Question: How do I return back to stock or another kernel.
    Answer: Extract boot.img, vendor_boot.img as well as dtbo.img from matching firmware you are on (you can do so by using this tool or similar ones found on XDA and when googling around) and flash them via fastboot. If you want to keep root flash back the magisk_patched_boot.img. Or dirty flash your rom and re-root.

    Question: Why is having Magisk installed mandatory for this kernel?
    Answer: The kernel uses a ramdisk overlay to apply some settings after boot. If you are not rooted these settings will not get applied and you miss some of the optimizations.

    Question: How to report bugs properly?
    Answer: Have a look at post #3 in the linked thread. The linked guide is a pretty good starting point.
    Before reporting any bug make sure you´re running on a stock configuration. That´s means you´re not using any mods, tweaks in kernel managers or other root tweaks , magisk modules, scripts or other modifications that alter various functions like sound mods, data traffic, sleeping behaviour, scheduler, magical battery tweaks 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 .zip of /asdf.
    Easiest way is immediately after booting up, with a root explorer navigate to /asdf. 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!

    Update to 1.1.0

    Hey guys and girls,


    I hope everyone is having a good day or starting into one. Here´s the next update.
    I forgot to include wireguard in the release. That´s now added.

    Since we´re not building a QGKI kernel, but rather a standalone kernel an important config that feeds information to the powerhal daemon didn´t get fully built, since the QGKI dependency wasn´t met. This resulted in lags in games like NieR.

    Also fix certain games like 7DS (com.netmarble.nanagb) crashing frequently on startup.

    thanks to @twistedumbrella for reporting the bugs and noticing wireguard missing.


    More changes in the Changelog below:


    Changelog:
    - add wireguard
    - enable qgki part of msm_performance to fix lags in certain games
    - fix some games ( for example 7DS (com.netmarble.nanagb)) frequently crashing during startup

    Instructions can be found in the OP!
    But look at this post too :)

    Have fun, enjoy the kernel and your phone.

    How to pass Safetynet after unlocking the bootloader

    With the introduction of hardware backed safetynet attestation, passing safetynet has become a lot more complicated.
    Some probably remember a while ago, flashing a kernel that forced some flags was enough to pass it. However these days are gone.
    Below is a short guide how to pass safetynet on phones that are flagged to use HW attestation (such as the ROG 5).

    1. Make sure you´re running with a working magisk environment on your phone.
    2. In Magisk Manager install both the "base" Riru module and Riru-LSPosed magisk module and do a reboot.
    3. After reboot make sure magisk hide is enabled in magisk manager
    4. Download the latest Universal Safety Net Fix from @kdrag0n ´s github and flash it in Magisk Manager. Reboot.
    5. Profit

    Update to 1.4.0

    Hey guys and girls,


    I hope everyone is having a good day or starting into one. Here´s the next update. It´s a rather big one.
    I´m a bit short on time, so I don´t have time for a bigger writeup, but the changelog is below. All of that adds up to quite a lot.

    The kernel is updated for the latest firmware:
    18.0840.2111.196. Make sure to update to the latest firmware before flashing the kernel to have no compatibility issues.

    Flashing the zip should now work fine from everywhere as the ak3 zip has been updated.

    The link to the WW firmware can be found here:


    More changes in the Changelog below:


    Changelog:
    - Import ASUS_I005_1-18.0840.2111.196 source code
    - Linux-Stable Upstream to 5.4.161
    - Merge CAF (QCOM) upstream
    - remove logging while device is suspended
    - improvements to deep sleep power consumption (ufs driver, auto hibernate)
    - reduce auto suspend delay in various other drivers
    - improvements on various subsystem like memory management, bluetooth, display, gpu etc
    - implement LRNG (thanks @arter97, see arter kernel OP for more info )
    - updates from kernel common for several subsystems
    - updated ak3 zip, thanks to @osm0sis
