[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] HugoClaw:
CKEH9​

Made for the Huawei Honor 9 based on EMUI9 sources​

I began this project because i wanted to bring the joy i felt from having JBolho's work on my Honor 9 with EMUI 8, and since he no longer owns the Honor 9, i wanted to bring some joy for those who appreciated his work, since my work is basically me cherry-picking some of his work.​

By saying this i'm not saying i'm an expert in the custom kernel world, it's the opposite, i'm a noob, curious enough to try my luck and see what i can achieve.​

For me this part is not necessary to include because all of you who try to flash either custom kernel, custom ROM or any kind of modification, should be aware of the risk and take full responsibility for your actions. So, that being said, i'm not responsible for your actions, try this at your own risk and responsibility. Don't complain about bricks, or any other kind of problems you might have from flashing this kernel. Be aware that your warranty is voided after you unlock your bootloader, flash kernels, roms and others.​

Features

​

- Advanced TCP Algorithms with "Westwood" Default

- Huawei's Analytics Engine disabled

- Swap and zram disabled

- Maple, SIOPlus and Zen additional I/O Schedulers

- GPU Scene Aware (set as default)

- Energy Aware Scheduling (EAS) with "Schedutil" CPU Governor, Schedutil set as default

- Reduced Kernel Wakelock Sources​

Requirements

​

- Unlocked Bootloader

- Rooted EMUI 9

- SD Card
​

Instructions

​

- Place kernel in external storage (SD Card)

- For flashing, i'm using EX Kernel Manager from playstore (it's a paid app)

In the Ex Kernel Manager go to:

Tools

Flasher

​

This is currently only being tested in OpenKirin's RR based on EMUI9

My English not very well. I am from Russia.

Hello! please tell me! Will there be support IPTABLES, which is necessary for fixing TTL?
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] dante.:
Great! Glad to see something new happening in development on my H9, this could make me update to Pie again, since the first time I tried it i felt Oreo was a lot more fluid with JBolho kernel than Pie with stock.
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] HugoClaw:
I'm sorry, but i don't know how i can do that, can you help me understand it? Or maybe send me a link of an implementation.

Try it out and give me your feedback :D
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] diffgas:
I have a link where you can find instructions to include TTL with IPTABLES rule. But it is written in Russian. I would really like to learn how to do it all myself, but my hands are very crooked!((
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] diffgas:
Why is there no one here?
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] madoxx77:
Can this work for P10 since it has same SOC ?
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] HugoClaw:
At the moment, no. I still have to make a build for the P10 :)
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] NOVOSEL:
Honor 9

My greeting! Tell me please, will there be any support in the development of your custom kernel for EMUY9 stock firmware? I'm sorry for the translation, I'm from Russia.:скрещенные пальцы:
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] HugoClaw:
Hello,

Yes, this kernel is supported on stock firmware :D

BTW - Version 1.2 is out.
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] NOVOSEL:
Great! Thank you for your hard work! Everything works fine on EMUI 9 firmware drain 163 (stf l09 c10)
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] diffgas:
Tell me please, the rule of iptables included for fixing TTL?
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] diffgas:
Will it work on 9.1?
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] Haru2001:
I need new link for this.

:/
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] Haru2001:
Sir do u still have the file for this kernel
[Honor 9  ROMs, Kernels, Recoveries, & Other Develo] Ceynan:
Are you still developing this project now？
[Samsung Galaxy J5 Themes, Apps, and Mods] Zaid Koudmani:
can i root j510h with magisk?
[Samsung Galaxy J5 Themes, Apps, and Mods] garylawwd:
Ya just flash magisk zip in twrp.

Magisk should work on all androids
[Samsung Galaxy J5 Themes, Apps, and Mods] Zaid Koudmani:
Thanks ❤
[Android Head-Units] jfinesse2000:
Hi, I just joined the site because I’d like to put a new head unit in an older car that may not have a long life left. Anyone know anything about this unit? And how this is possible?! Is this a scam?

There is a unit on eBay for $12.99 from China

I can’t post a link because I’m new here
[Google Pixel 2 XL Guides, News, & Discussion] pbman1953:
Like some I'm on Beta 3 of the new Q . Ever since the install, my first dark screen will not change when touched. I have to hit the power button to make the screen change and with repeated swipes the desktop shows.

Will a factory reset help? Plus will Q be the program that lands after a reset?

Thanks
[Google Pixel 2 XL Guides, News, & Discussion] Aerosolx:
I had similar issues. I actually had alot of issues. I tried beta 2... Factory reset.. Few days later 3 was released.. Tried again.. It was still awful.. Reset again and im back to pie. I loved fluid nav you loose that along ith a bunch of other stuff.. The beta is just that... Beta.. Its azz right now
[Google Pixel 2 XL Guides, News, & Discussion] pbman1953:
Just went back to apple pie myself.

Good advice
[OnePlus 5T  Questions & Answers] tjhiwa:

F2FS Tutorial

Notice!! Backup your internal storage and your

Data

partition

Thanks to [MENTION=5877792]tycoon78[stoner][/MENTION] for this amazing tutorial and for contributing and participating to make this kernel the best on xda

:highfive::fingers-crossed:

For people who want to use F2FS tutorial:-

-Go into

TWRP

and then simply go to

Advanced Wipe

-

[IMG="TWRP"]https://i.imgur.com/8wIq5us.jpg[/IMG]

-Now select

[Data]

-Now click on

[Repair or Change Filesystem]

-It will now display your filesystem info

-

[IMG="FS"]https://i.imgur.com/q1csViQ.jpg[/IMG]

-Now click on

[Change File System]

and Choose

F2FS

-Do the same procedure for

Cache

-After doing it..

reboot to recovery

and check if the partition still F2FS or changed back to ext4

-If it shows F2FS... flash the rom you want or stay on the same ROM

-Use this app to check filesystem after you booted to your rom DiskInfo

Reserved for future use
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
i think you double threaded...

also that twrp you linked to, although seems to work, the restore backup dosent work and basically when restoring would bootloop your device.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Xda is really weird.. :confused:

About TWRP.. I backed up & restored without any issues :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
you formatted/ cache too?

i had to completely go back to stock as the partitions formatted to the new file system screwed up something.

in that twrp build odm was also formatted to F2FS and it screwed with my csc and cell reception.

one thing i didint see or hear is what are the advantages of F2FS over the regular ext4?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
lol.. I'm sure you changed the wrong partition to F2FS maybe :D F2FS is only used on Data & Cache partition only :)

About F2FS advantages.. read here..

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
no i didnt forcefully change anything. i just simply resorted the backup. and while looking at the logs, the make f2fs is formatting odm!( twrp dosent alow you to wipe efs or odm, it will wipw/format though when restoring a back up!)

in the old twrp thread other are reporting issues too about boot loop. i got out of it but as i said odm partition was formatted to f2fs and i think EFS too! since reception was on and off...

also i hate to break it to you but 3 days ago [MENTION=9116297]Eamo5[/MENTION]:

so not the first....:(

edit also what rom base/ram disk is this kernel compatible with?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] L4WL13T:
Sounds very good! Downloading now to give it a go!
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
And I hate to break it to you.. but I am the first one... May 6... 5~6 days ago.. :cool:

Look at the screen shot.. May 6

We did it first and we motivated other kernel developers to implement it.. Sorry.. your info is outdated mate! :D
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
ok nice! i just understood by your OP comment that you were the 1st poster on XDA. also by looking at the commit dates on gihub of yours vs [MENTION=9116297]Eamo5[/MENTION]

anyways regarding the big issues with the new twrp:

https://xdaforums.com/showpost.php?p=79501974&postcount=479

that guy is also reporting issues check at his 1 st restore screen shot:

EFS and ODM

are being formated to F2FS !

edit

even vendor

also what rom base/ram disk is this kernel compatible with?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
He should untick on TWRP settings [use -rm instead etc etc etc]... it will then restore backup to the original state which it was ext4 :)

and this kernel compatible with Devbase Oreo or Stock Oreo ASB1 Build :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
i might try it down the road but i just spent hours and hours coming back from those issues so going to stay away from that new twrp for now.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
let's try this baby

silly question. this will work with pie right? because i see a lot of oreo mentions...
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Only for Oreo :) No love for PIE.. I only love Oreo:D
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
and why is that? i know, a provocative question but I'm curious to listen to your reasons[emoji173]️
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Mods & battery life/ performance ratio ;) the problem with PIE kernels is that any mod you try to apply breaks something else..while doing the same on Oreo stays rock solid stable and yet still provides performance and battery life even at stock compared to Pie kernels.

I still believe Pie needs time to mature enough but that's not the only reason I stay on Oreo and maintaining it;)

Some kernel mods breaks Pie kernel and simply doesn't work... biggest example is GPU OC :) in Oreo it works wonderfully and smoothly ;)

Also all mods & modules works for Oreo due to xposed officially fully functional with Oreo.. while Pie needs different kinds of hooks and hacks just to work... and not all modules works with edxposed :)

Don't tell me PIE is more secure.... you have just rooted your device...that's by itself less secure than unrooted device..

I believe Oreo gives the full performance potential to Note 9 compared to Pie.:)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
I've never experienced note 9 with oreo. which rom do you recommend from xda? if you don't want to tell, send me inbox. thank you

one last question. what advantages gives an overclocked gpu?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
I recommend Devbase Oreo or Light ROM Oreo or even stock Oreo ROM :) all works ;)

GPU OC advantages leads to increased performance & FPS when heavy gaming :) less lag and stutters.. especially when used or coupled with F2FS filesystem :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Nasty_z:
Hi,

Thanks for this kernel.

I'm assuming this kernel does not work with AOSP roms? Didn't see any mention of it in the first post..
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
delete
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] cylent:
Can i install this kernel on twrp 3.2.3-0 which i assume doesnt havent f2fs? or do i need to update to twrp with f2fs?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Only for Oreo TW :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Yes you can ;) the TWRP f2fs is only mandatory when you want to switch to F2FS.. other than that.. you can use any TWRP versions :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Update! :)

Is the gpu overclocked by default?i think the phone is getting hot
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Devon Grace:
why would you make this kernel for oreo only? pie has been out for ages
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] azZA_09:
Cause he wants and he can. Just wait, maybe he will release. You have endurance kernel till there
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
I get 70 celsius in cpu.what im doing wrong?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
yes :)

I am planning.. but not soon :) most features doesn't works with PIE.. it breaks it :(

Thank you :)

No body reported any temperature issues at all.. check your ROM.. there is something wrong :) I guess your ROM is full of bloat :D
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
im pretty sure my rom is the problem but what can i do with your kernel if i want to lower temp? i mean can i change gpu from being overclocked? i love your kernel but honestly i just flashed endurance now to test temp.

---------- Post added at 01:25 AM ---------- Previous post was at 01:22 AM ----------

also note that my temp problems started with latest build. maybe you should check it, i dont know

Beta Kernel!!

Simple LMK is implemented! We are the first kernel in the history of Note9 to have Simple LMK... lol even S9 ! :cool:

All other kernel developers couldn't implement Simple LMK.. and they failed.. miserably too :( so.. THEBOSS-Zeus kernel coming for rescue and shed the light on Note9 users :) we did F2FS first kernel compatible in the history of Note9.. and guess what?!

we did it again with Simple LMK on Note9

;)

Anyway.. lets stop here.. and get directly to the kernel stuff :)

This kernel is at beta stage due to Simple LMK and due to new feature (Simple LMK) is added but it boots.. and it works.. wonderfully too! :)

Changelog:-

-Debloated more lines and useless codes (lighter than any kernel in Note9 on XDA ;) pure cleanse :D

-Improved CPU-idle operation

-Fixes & tweaks & Improvements on sched/fair issues

-Improved CPU selection on light tasks

-Load balance between big.LITTLE cores

-Prefer CPU energy efficient for idle tasks

-Use CPU aggregating loads

-TCP tweaks [speed improvement]

-Prohibit long procedures for kasan operations

-Improved entropy

-Improved binder functions

Sorry, I was maybe too harsh. What I meant was that dev can do whatever he wants. If his kernel is for Oreo, we should let him be. He will release it when he will decide

Sorry for sounding too harsh, real life problems dont have to be integrated in my posts. Sorry again!

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] anastasiszn:
good :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Only made for N960F... I never mentioned that it would support N960N :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
there is no reason it wouldn't work. the n960n is virtually identical to the F.

he probably flashed it on top of Pie or something.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] tycoon78[stoner]:
Check yourself by using other kernel. N then use this kernel u will notice urself the app installation gets more faster n rom is more smoother with f2fs n fsync disabled.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
no.

Hi guys, I've read the whole thread but I still can't figure out if this kernel is for OREO only. Is it?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] karapoutsoglou:
yes. only for oreo
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Brutale1090!:
Do you know any pie kernel which allows a decent GPU overclock?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] clustered:
When would your kernel for Pie will come out? Or you don't have plan to release kernel that support Pie? Thank you.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
I am actually trying to build it :) and things is not looking good actually since not all my features works for PIE biggest example [GPU OC & UV] :rolleyes: with some boot issues really.. it seems PIE kernel is not flexible enough as Oreo kernels on extraordinary features :D

Without my special features that I offer.. there will be not enough difference between my Pie Kernel compared with others kernels on xda... :) but I keep trying.. don't worry ;)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Sultanxda:
Hi, can you help me implement Simple LMK too?? Incredible you are the only one who got it working, wooow :0
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Lol.. :D I meant that no one got it working with N9 except my kernel ;) I never meant worldwide :fingers-crossed:

Check xda on S9 and N9 threads.. no one could implement your SimpleLMK on those two devices.

Post will be edited now... Done.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] emuashui:
OP, I'd like to try your Oreo kernel THEBOSS-Zeus but it will take time for me to prepare eg. backing up kernel , check TWRP and flash it etc... before that, could you tell

where the Oreo kernel will have positive/negative/unchanged impact on camera quality?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] naya28:
Hi Da Boss,I m running your kernel on O8 and it gives me a really smoth and responsive note 9

benchmark results are better than Pie.

I m a little afraid to switch on recovery with f2fs cause my english is not good enought to understand whats really happens if I face issues but this kernel is a bomb.

good Job Sir

thanks a lot:)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Camera is perfect as it is... the kernel doesn't have a role for making the camera better or worse.. it is always usually ROM side... not kernel side :)

I have heard that PIE causes camera to perform poorly but Oreo preform better than PIE on all conditions :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
Thank you :fingers-crossed: take your time and Google it to have enough information about f2fs :)

I always recommend to use f2fs (if you know what you're doing) :) it provides smoother operations on all usage.. no matter if it is multitasking, gaming, etc.. ;)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] naya28:
okay,and what about the backups with ext 4?

I mean flash new recovery,format data and cash to f2fs and then what I have to do?

will my system will reboot or should I have to dirty flash my rom...?

that s why I m not sure

---------- Post added at 03:08 PM ---------- Previous post was at 03:01 PM ----------

I use root to have the best performances with my phone,since 10 years now...so you can be sure that i m gonna use 3.3.1 twrp if it s give me a efficiency(?)phone...Bobber 113 said he has some issues with this twrp...that s why I m not sure
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Da-BOSS:
I always recommend to do that when clean flashing the ROM to avoid any possible issues :) but if you want to do not lose data while converting to f2fs...

before restoring backup

go into TWRP settings and put a tick on the checkbox at [Use rm -rf instead of formatting] and then restore your backup file :)
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] naya28:
got it!
