Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A40.
The custom kernel has been named Eureka which is a greek work which means "I have found the solution". This multi-purpose kernel is the solution for battery, gaming, performance for A40. On creating this kernel, I believed that 1 kernel can be all of the above if properly tweaked!
As from Eureka R9.0, four kernel variants are available inside 1 same zip. This has been made possible using AROMA Installer.
Compatibility:
This kernel is compatible with AOSP GSIs/ROMs, OneUI2 and OneUI3. As from R9.0, there is only 2 variants of zip to download. One is called EMS and the other one is called HMP. Continue reading to learn more about them.
FEATURES:
* Disabled Samsung security features
* Enabled all governors + added other governors
* Overclocked CPU as follows:
BIG Cores: from 1768 MHz to 2288 MHz.LIL Cores: from 1586 MHz to 1794 MHz.* Underclocked CPU as follows:
BIG Cores: from 936 MHz to 208 MHz.LIL Cores: from 839 MHz to 208 MHz.* Added GPU thermal and voltage control
* Added latest boeffla wl blocker V 1.1.0 and disabled some wakelocks
* Network speed improvement
* Enable zram support and set default compressor as zstd.
* Switch to a lower charging voltage more quickly.
* GPU max frequency overclocked from 845 MHz to 1300 MHz
* Implemented Dynamic FSync 2.0
* Implemented a custom hotplug driver to enhance battery management
* Implemented Power Suspend driver
* High torch brightness on custom roms/gsis
* Has Spectrum support
* Automatic detection of magisk - If u are rooted, u don't need to flash magisk after kernel.
* Upstreamed kernel version from 4.4.177 to 4.4.302
* Built with Vortex Clang 14 toolchain with LTO. Reason: Better performance
* Support for EMS (Exynos Mobile Scheduler) added
Please read the changelog on github for full list of changes.
KNOWN ISSUES:
* Maybe ADB cannot be used at the same time as MTP
SOME MINOR TWEAKS FOR BEST GPU PERFORMANCE:
* Set GPU power policy to "always on"
* Set min and max GPU frequency to 1200/1300 MHz
* Disable GPU thermal manager to prevent GPU frequency from dropping
* Games don't require high CPU frequency because they depend more on GPU. You can therefore decrease CPU max frequencies to reduce heating of the device.
We have developed our own kernel manager called EKManager which is a fork of HkTweaks. It is compatible only with Eureka Kernels. You can download it from here:

Reference about EMS kernel:
Energy Aware Scheduling (EAS) gives the scheduler the ability to predict the impact of its decisions on the energy consumed by CPUs. EAS relies on an Energy Model (EM) of the CPUs to select an energy efficient CPU for each task. Allowing to save up battery even further. EMS aka Exynos Mobile Scheduler, is a fork of EAS for Exynos. We ported to our 4.4.y kernel. As written above, EMS kernel is good for battery saving. Some words from kernel official docs: - EAS operates only on heterogeneous CPU topologies (such as Arm big.LITTLE) because this is where the potential for saving energy through scheduling is the highest.
EMS kernel + pwrutilx governor is very good at battery saving according to our test.
Reference about HMP kernel:
It's just the stock scheduler that comes with stock kernel. Basically it's the normal kernel.
What kernel variant to flash once inside AROMA installer?
1) AOSP Legacy Q/R/S - If you are using an old Eureka ROM which was released before February 2022, choose this.
2) AOSP Q/R/S (New) - If you are using an Eureka ROM built as from February 2022, choose this.
3) OneUI 2 - For any OneUI 2 roms (stock/ports).
4) OneUI 3 - For any OneUI 3 roms (stock/ports).

Huge thank you for this great job
Works nickel on my firm stock
I don't play, I wouldn't vote.

In the end someone created a modified and stable kernel and with no bugs for our device. I have been waiting for this a long time. I haven't tested it yet, but thank you in advance. Great work, go on man.

Glad to see the community of A40 growing up!

wow .... great job .... congratulations ... I have installed now .... fast and fluid device only that the maximum frequency of the big ones does not select 2880mhz .... only 2184 .... definitely not a kernel problem but some setting

Hi,
Yeah, max frequency is not selected automatically because newer Exynos's kernels are very complicated. Their is no fix to this issue in any kernel at this time. But max frequency can be used by setting min and max frequency to that value.
Thx for your feedback

hoooooo .... it goes great ...

1- How is the installation done?
2- How can I return to the stock kernel?

Hi,
Just flash kernel in twrp and reboot.
If you wish to return to stock kernel, backup your boot and dtbo partitions before flashing my kernel.
To return to stock kernel, restore boot and dtbo backup.

thank you. but forgot to backup what else can I do?

There is a bug when switching from router-wifi to wifi and vice versa
Still great work

Extract boot.lz4 and dtbo.lz4 from stock firmware (AP file). Compress both files in a single .tar archive.
Flash this .tar file in AP slot in Odin.
Tool to compress and decompress archives on windows is 7zip standard version available for free on the web.

LONG TERM SUPPORT :-
This kernel will be supported for a long time with updates directly streamed from CM kernel sources i . e . as long as CM keeps publishing updates to Motrola's Kernel, this kernel will also be updated.
Further, I will also be personally adding features to this kernel along with tweaks and optimizations as and when needed.
DOWNLOADS :-(do not mirror my links)[ Latest Version ][ Older Versions ]
TEST BUILDS with OC & UV :-These builds contain the following extra features ( when compared to normal /stable builds ) :-
CPU OC to 1593.6 MHz
CPU UC to 96 MHz
CPU UV hardcoded and can't be changed
Associated RamDisk changes
Since OC will not work without associated ramdisk changes, hence test builds are available as boot images rather than anykernel zips.
Now there had been reports of bootloop with blisspop & rr roms and certain other roms. I looked into this and found out that even though they are based on cm kernel, their ramdisk sizes are different, hence bootloop on using boot.img but no bootloop on using anykernel zip ( since, anykernel works irrespective of ramdisk size).
Now it is highly unfeasible to build a boot.img for every different rom and upload them separately. Hence, I have decided NOT to include OC/UC in the stable builds.
Hence these images will only work on aosp and cm13 roms.[/I] Any rom having ramdisk size different than that of official cm13 or official slim(aosp), will not be supported. Hence no support for OC in rr/bliss.
INSTALLATION INSTRUCTIONS :-
Reboot into recovery.
Make a nandroid BackUp.
Select Install zip from SD Card.
Select the Downloaded zip (different builds are present as an option in AROMA).
Then Reboot to System.
RECOMMENDED APPS FOR KERNEL TWEAKING :-
Kernel Adiutor
Faux123 Kernel Enhancement Pro
I do not support any other apps.

It works very well!
The overclocking is overvolting the CPU? Or it just changes the frequencies?

You shouldn't face any issues with camera, which ROM are you on ??
For TCP try Westwood.

Hello,
Will be possible to make it for CM12, if I install, the camera stops to work, the rest work perfectly.

This kernel is strictly for marshmallow based roms only.
However if you want to use it on lollipop based roms try an older version.
You can download it HERE.

Will give that a go. From what I could see yesterday this version worked fine with Lollypop apart from the camera.
Edit
Seems that kernel won't run the processor any faster than 787.
Is there any chance of updating to include over clock or modding current version to work with Lollypop camera?

The kernel works on 'x' ROM?
This kernel is made to work on all KitKat ROMs, since it have a script to change only the kernel (the core) and make ramdisk untouched
This works on Stock KK ROM?
Yup, @ECr34T1v3 tested it (not tested on R8A and R8B).
This kernel have clock bug?
No, it's fixed on R7.
This kernel is unstable?
No, we try to make it more stable possible and also daily usable.
This kernel works on Lollipop?
Yes, but only R8A and R8B.
Why R8A and R8B?
Both are based in R7, but R8A is oldest, since I found the fix to Lollipop ROMs in R8B.
R8B have more features compared to R8A, because R8B is partially synced with SAndroidKernel v1.3, and because it two packages

AFAIK, overheating is the most common issue of sc8830 SPRD SoCs. I've made kernels for Core Prime, so I know this. Also, max and min CPU freq can't be changed. If you touch max freq, both max and min freq will push to maximum freq (with this kernel is 1,3GHz)
I suggest no-OCs on the kernel, else lots of people will face overheat

Exactly, the overheating problem is difficult to be solved, because the CPU is not the best. But we can improve something with this kernel. Just one question, the CPU remains constant or not? Here time is, but returns to normal..

Umm... what do you mean "constant"? If the CPU can be non-overheat then nope, we can't deal with it. You know Snapdragon 810 right? This is an example for us. There's a way to reduce overheat: Reduce CPU speed, as 1+ does with its OP2

Its can be 100? confirmed the problem is overclock? Or only testing to know?
I said to Erik (i never will remeber that crazy nickname ), to test kernel in Stock ROM, since its not much diff from OpenSource (except I/O, Mali400 and Android Fragments).

i suggest non oc kernel too
cpu freq 600-1200
this kernel is very very stable, but oc makes me afraid my phone will be explode

Umm... what do you mean "constant"? If the CPU can be non-overheat then nope, we can't deal with it. You know Snapdragon 810 right? This is an example for us. There's a way to reduce overheat: Reduce CPU speed, as 1+ does with its OP2

I installed the Stock ROM (Firmware Argentina) via Odin last night. I installed in OMKernel in Stock and I boot normally. The CPU was no bug in the clock, but returned time. I did the following, applied to 1200MHz Frequency (Max) and 200mhz (Min), applied on reboot and restarted the phone. When I went to check, the nuclei were in constant 1300MHz .. selected minimum frequency 200mhz again and the cores back to normal. But I always came back to stay constant. I did the following, changed the maximum frequency. I put it in 1300MHz and the minimum at 200mhz and restarted. So far it was not constant here in Stock. Does that mean anything? :victory:

Constant like same all time.
Its can be 100? confirmed the problem is overclock? Or only testing to know?

KKJKKKKJKJKKKKKKJKJ... I think there is no risk of blowing up the phone, bro. I tested here in stock and is very stable. And not Overheat :silly:

Pero no entiendo como se instala es como ponerle una nueva ROM o es una actualización por favor podrías explicar como instalar

New frequecies table will be:
1200Mhz [Max], 900MHz, 600MHz, 300MHz [Min]
With right proportional voltages
This step is test, after i will put other 5 freq since the driver only support it

For users and devs!!
All my kernels are based on cyanogenmod/lineageos source ,if someone who believes" i stoled their source" i have video captures and anyone who believes something just report me and i will have the last laugh .every tweak/mod/feature i used i edited/tweaked on my own and anyone with problem just stay away. My sources are free for anyone and can be used(i saw some ppl use them already)i don't care like other devs and i am happy and proud if someone use my work(the words" i work many hours on that project" the best repeatable words(many devs without the recognized tag and not with many thanks,they have worked for many hours/days/months and they don't cry and fight other devs )if for some devs their source are so much rare and hardworked just keep them privet(their work include their name so no problem ...we are not here for the fame ...we just want to improve the devices to make them better and not to fight with each other...
Why i am telling you all these?!
I have had many kernels unreleased from fights...i will continue to new clean projects based on lineageos and i will not care much with my source to wait many days to upload them with all the history of them because 2-3 "devs" they believe i used or edited their source...i am not a popular dev but you can't believe and no one knows how many days without sleep and hours of hardwork i have done, to do all this(and many not release source/work, much more than other devs...

This kernel is for cm14.1 and roms based on cm. So I guess rebased LineAge OS is also supported?!? OC and UV works without loosing stability?

Does this work for Fulmics ROM(based on v20a H850)?

Maybe it is included,you tried it if it work? I ll check it again in a few minutes.

It works very well. There are a couple things I've noticed though. Using the hotplug control, setting the number of cores does not stick. Also on CPU frequency maximum if you try to change core 2 or 3 the max shows 1593 MHz instead of the higher values of these cores. Also there is no GPU control. But overall it is very stable and have been using it since you released it. Looking forward to more features and thanks for your development.

Okay so using the regular kernel auditor setting CPU max for both the little and big core configuration works correctly (able to properly set max CPU speed). Also able to change GPU speed settings. But hotplugging option to change max cores not available in kernel auditor, so not sure that's fully implemented in your kernel yet? Also like your version of kernel auditor for screen settings where you can choose preset profiles. But overall the regular kernel auditor does seem to work better.

Awesome kernel
Best alternative to starkz kernel

Impressive spectrum profiles!
No need to tinker stuff, the spectrum profiles are great for each purpose. You can unleash the beast and saving battery on the same kernel! Great work, dev.

Great work sir :good:

woooow!!!!!, testing, installation no problem, great work

Gonna give it a try
Can I flash this custom kernel over the other custom kernel I'm using now?

idk about this version tho, just try it bro.
After facing "Encryption Failed" thing u can still flash boot.img afterwards. Try it won't hurt.

this high OC is no danger to the life of the device?

Thanks for this awsome kernel.. Install and working good on oreo LOS extended by alexey.
Can u please add an iptable/netfilter module on ur next released?
Thanks.

I recommend the oc version, use spectrum battery profile as daily driver and spectrum gaming profile for heavy task like gaming.
If you want to unlock mido's potential and you do gaming but still can save battery while needed, go OC.
If you don't need extra power, go non OC.
But it all depends on you.

It's always at risk, especially battery life
My advice is when you're using this kernel especially the OC version (gaming)
Install external cooling device, it's quite cheap

great work, is it possible to correct the brightness control buttons?

[KERNEL][CUSTOM] Eureka kernel for all variants of Galaxy A30s for android 10(Q) & 11(R) & 12(S) ROMs

Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A30s.
The custom kernel has been named Eureka which is a greek work which means "I have found the solution". This multi-purpose kernel is the solution for battery, gaming, performance for A30s. On creating this kernel, I believed that 1 kernel can be all of the above if properly tweaked!
As from Eureka R9.0, four kernel variants are available inside 1 same zip. This has been made possible using AROMA Installer.
Compatibility:
This kernel is compatible with AOSP GSIs/ROMs, OneUI2 and OneUI3. As from R9.0, there is only 2 variants of zip to download. One is called EMS and the other one is called HMP. Continue reading to learn more about them.
FEATURES:
* Disabled Samsung security features
* Enabled all governors + added other governors
* Overclocked CPU as follows:
BIG Cores: from 1768 MHz to 2288 MHz.LIL Cores: from 1586 MHz to 1794 MHz.* Underclocked CPU as follows:
BIG Cores: from 936 MHz to 208 MHz.LIL Cores: from 839 MHz to 208 MHz.* Added GPU thermal and voltage control
* Added latest boeffla wl blocker V 1.1.0 and disabled some wakelocks
* Network speed improvement
* Enable zram support and set default compressor as zstd.
* Switch to a lower charging voltage more quickly.
* GPU max frequency overclocked from 845 MHz to 1300 MHz
* Implemented Dynamic FSync 2.0
* Implemented a custom hotplug driver to enhance battery management
* Implemented Power Suspend driver
* High torch brightness on custom roms/gsis
* Has Spectrum support
* Automatic detection of magisk - If u are rooted, u don't need to flash magisk after kernel.
* Upstreamed kernel version from 4.4.177 to 4.4.302
* Built with Vortex Clang 14 toolchain with LTO. Reason: Better performance
* Support for EMS (Exynos Mobile Scheduler) added
Please read the changelog on github for full list of changes.
KNOWN ISSUES:
* Maybe ADB cannot be used at the same time as MTP
SOME MINOR TWEAKS FOR BEST GPU PERFORMANCE:
* Set GPU power policy to "always on"
* Set min and max GPU frequency to 1200/1300 MHz
* Disable GPU thermal manager to prevent GPU frequency from dropping
* Games don't require high CPU frequency because they depend more on GPU. You can therefore decrease CPU max frequencies to reduce heating of the device.
We have developed our own kernel manager called EKManager which is a fork of HkTweaks. It is compatible only with Eureka Kernels. You can download it from here:

Reference about EMS kernel:
Energy Aware Scheduling (EAS) gives the scheduler the ability to predict the impact of its decisions on the energy consumed by CPUs. EAS relies on an Energy Model (EM) of the CPUs to select an energy efficient CPU for each task. Allowing to save up battery even further. EMS aka Exynos Mobile Scheduler, is a fork of EAS for Exynos. We ported to our 4.4.y kernel. As written above, EMS kernel is good for battery saving. Some words from kernel official docs: - EAS operates only on heterogeneous CPU topologies (such as Arm big.LITTLE) because this is where the potential for saving energy through scheduling is the highest.
EMS kernel + pwrutilx governor is very good at battery saving according to our test.
Reference about HMP kernel:
It's just the stock scheduler that comes with stock kernel. Basically it's the normal kernel.
What kernel variant to flash once inside AROMA installer?
1) AOSP Legacy Q/R/S - If you are using an old Eureka ROM which was released before February 2022, choose this.
2) AOSP Q/R/S (New) - If you are using an Eureka ROM built as from February 2022, choose this.
3) OneUI 2 - For any OneUI 2 roms (stock/ports).
4) OneUI 3 - For any OneUI 3 roms (stock/ports).

That's awesome! I will try your kernel on my A30s running One UI asap, and I will let you know how it goes. I have a few questions tho. I just have to normally flash through TWRP after wiping dalvic right? You have written that you both overclocked and underclocked the CPU, so can I choose one, and how? Do I have to use the kernel manager you linked? If no, then what do I use the kernel manager for?
Again thanks a lot for making this kernel, and I will let you know how it goes when I flash it.

Hi bro,
You just need to flash kernel in TWRP and reboot. If you are using magisk 20.4, then kernel will automatically upgrade it to 21.0 (latest) .
My kernel has spectrum support whereby the profiles play with the different overclocked and underclocked cpu frequencies accordingly.
I recommend using HkTweaks kernel maanger because its the best for Exynos devices and all my kernel features can be customized through it.
If you want more support and get help from other A30s members, kindly join telegram and join the support group: https://t.me/eureka_support_group

Thanks a lot!
Okay, another question - I want to test the ROMs that have been built, but I am daily driving One UI right now, and I don't really want to daily drive a ROM until it is stable, so if I make a nandroid backup, will everything get backed up, even though I am on stock ROM?

the performance of the kernel is great but it suddenly freez and restart the phone....i tried with both one ui and custom rom......both have same issue...i think the kernel need to be more optimized.....bu the way thank you so much for the kernel...i was so frustrated for not having any custo, rom and kernel for better performence......but your this help makes me so happy....

Not all phones are manufactured same
Some phone can use the overclocked frequencies and some can't
If you are getting random reboot, decrease big cores' max frequency to 2080 MHz.

Ah gotcha. Thanks!
I have another question, sorry if it sounds stupid, but I am really not comfortable losing my data XD
I know now, how to backup everything, but how do I backup my data and then reflash it after flashing a ROM?
Can I even do that or no?
If yes, do I just backup the data partition and flash?

If you are on stock rom (oneui), you can flash your os again with Odin but also keep your data. You have to use "home_csc..." Instead of "csc..." in the CSC slot in Odin.
Usually with GSIs, you don't need to wipe your data. So a backup of your data via twrp should work. If you are changing to a gsi and the phone is stuck at the Samsung animation logo, then u can go to recovery and wipe dalvik cache and reboot. If still stuck, then u will need to wipe data.

Does this affect the GPU long-term-wise?

Oi sabe como desinstalar esse kernel tem alguem arquivo zip para flashar no twrp?

Eureka R6.5 update for A30s
Changelog:
-> Further overclocked BIG cores from 2080 MHz to 2184 MHz.
-> Undervolted the whole soc (exynos 7885) including CPU and GPU.
-> Tweaked kernel for stability and less battery drain at high frequencies.
-> Enabled back 312 MHz and 343 MHz frequencies for big and little cores respectively.
-> Fixed automatic scaling to overclocked frequencies. No need to force frequencies now!
-> CPU throttling bypass increased till 2184 MHz for big cores.
-> Automatic detection of root when flashing kernel. If you are already rooted, you won't lose root when
flashing kernel as from now. So, no need to flash magisk after kernel!!

As mentionned clearly on the thread, there are 2 versions of Eureka available. One is called 7.5 R and one is called 7.5 Q/R
R is for oneui 3 only
Q/R is for other roms/gsis

Any tips on how to flash this? TWRP from official site doesn't work, the ones on CDA have dead links, and im unable to install OrangeFox. A307FN rooted with Magisk v23.0
