Hello, I have 2 custom roms for my phone, they are gingerbread based stock roms. One has perfect ram management (strict), and the other has more relaxed ram management settings. The first rom runs smooth and has great battery life, the second still runs fairly smooth, but has some app instability do to low ram, and the launcher closes often. Battery life is not as great on the second rom. But the second rom has some great additions to the first, that I would rather not loose. I would like to transfer the lowmemorykiller settings from rom 1, to rom 2. Or edit the settings in Rom 2 somehow. However I'm a noob, and have windows, and cannot make sense of splitting the imagefile, editing the ramdisk and repacking it to a flashable image. Is there a way to change the settings with root manager? OR an iso image editor, or something that can open the img file, and allow me to edit the ramdisk, without linux, and special coding and fancy wizardry?
Sorry for the long post. Another alternative was to swap the boot.img from the two roms, but I'm not sure what other settings were changed in it.
Any thoughts or tips would be greatly appreciated.
Ok, sorry I asked. I just figured someone here would know how, and might care to share some tips.
The first time I made AdaMax was for the Chinese Galaxy S4 Duos GT-I9502. I ported Adam kernel and added more tweaks from other kernels like Persus, halaszk (5420). After several releases, I decidec to spread this kernel to more models. So I built the v8 for both Chinese and international GT-I9500. This thread it for hosting it.
This week, i successed compiling for the s4 with 5410 cpu. As we know GT-I9500, GT-I9502 and SCH-I959. They share almost same compiling configure and their own ramdisk. So I compile them together with almost same features.
At last, I have to make following declarations, AGAIN:
Take your own risk and responsibility on flashing this kernel. I am not responsibale for any loss of your hardware, software, data or warranty.
Read this OP from start to finish before flashing the packages or asking any questions. There is a Q&A section. Any questions already answered will be ignored by me and may be insulted by other members. So save your your keyboard, your time and your data traffic.
No ETAs.
Don't ask me to make this kernel for a specific rom. There are basically only two kinds of roms, AOSP and TouchWiz. So I compile for these two kinds with differnet SDK levels. If it dose not work on some rom, don't blame me and ask me to adapt the rom for it.
If you found a new version, but its download link is not directly showed in this OP, that means it is a version I don't think good enough to be a release. So take your own risk to use it. I will remember your feedback, try to make changes, but not respond with posts.
Thanks to a lot of people, I will add their names here... @wanam, [email protected], @Dees_Troy and Team Win, @AndreiLux
As my habit, I always put the download link first:
v15: https://github.com/maxfu/android_kernel_samsung_exynos5410/releases/tag/v15-9500
File name instruction:
touchwiz: for most used international GT-I9500 with exynos5410 cpu.
aosp: for AOSP KitKat 4.4 roms like CM, ramdisk comes from CM 11
kk442: kernel for KitKat 4.4.2
jb43: kernel for Jelly Bean 4.3
jb442: kernel for Jelly Bean 4.2.2
lite: live version is built with stock zImage and maxfour initrd. It has limited maxfour features. And sometimes selinux f**ks up the STweaks.
boot: system kernel package
recovery: recovery kernel package
kernel: system + recovery combined kernel package
*.tar/*.tar.md5: Odin package
*.zip: CWM/TWRP recovery package
example.1: boot-i9500-aosp kk442-v10f1tc.zip means a system kernel image CWM/TWRP flashable package for international I9500 with TouchWiz KitKat 4.4.2 roms.
example.2: kernel-i9500-aosp-kk442-v10f1tc.tar.md5 means a system recovery combined odin package for international I9500 with AOSP roms like CM.
Old versions:

You can always go to the following addresses to see whether there is a new version:
https://github.com/maxfu/android_kernel_samsung_exynos5410/wiki
https://github.com/maxfu/android_kernel_samsung_exynos5410/releases
I open the issue section for the source code, you can report problems here. Please provide at least version aosp/touchwiz jb/kk.
https://github.com/maxfu/android_kernel_samsung_exynos5410/issues/new
The source code:
You can
git clone https://github.com/maxfu/android_kernel_samsung_exynos5410.git
git clone https://github.com/maxfu/initramfs_samsung_galaxy_s4.git
git clone https://github.com/maxfu/toolchains.git
use the build.sh for exynos in toolchains/script ro build the kernel.
you need to su before build the kernel cause the ramdisk belongs to root.
Since this is a side product of my kernel for GT-I9502 which is the phone I am currently using. I don't actually test this build for GT-I9500, so I really need feedback. And please backup your rom before using this.
Features:
Built with OSRC KK 4.4 source and ramdisk, now it should work on many 4.4 roms.
Contains most features from Adam kernel including Wolfson Audio Control. For I9502 which uses yamaha sound chip, Wolfson Audio Control will be hidden automatically since it does not work.
From v10, the kernel is renamed to MaxFour due to wamam's request.
Kernel + Recovery release at one time, recovery based on TWRP with EFS_GSM (for Chinese Duos devices) support.
Compiled with GCC 4.8 toolchain from Google NDK r9c.
Packed in LZMA format to make smaller images.
Native exfat support based on OSRC exfat source code.
UCI script for STweaks and may be others.
Unlocked some hidden CPU frequency: 2.0GHz, 1.9GHz, 1.8GHz, 1.7GHz, 800MHz, 700MHz for big cores; 1.3GHz, 1.2GHz, 400MHz,
300MHz, 200MHz for little cores. Frequencies over stock like 1.7GHz for big cores and 1.3G for little cores are implemented in tc*/overclock version.
Added more STweaks settings which are not included in Adam kernel, including CPU power management, Tools with reboot options, GPU settings, CPU governor.
Android logger is compiled as standanlone module, so user can disable it completely to save power.
Tc/overclock version contains Persus dvfs for GPU with 700MHz overclock, thanks to AndreaLux.
Built-in Seeder entropy generator to provide lag reduction although it is not significant as it was on Gingerbread.
Built-in busybox with auto-installation.
Optimize on ram.
Added several I/O Schedulers including ZEN and ROW.
Built-in dynamic eMMC read ahead
Built-in Asynchronous Fsync
Compiled with compile flag for Cortex-A15 and NEON
Disable KNOX and SELinux when booting, selinux will be set to permissive with the boot command line.
init.d support.
A lot of changes and fixes.
Disabled a lot of rarely used devices support.
PS:
*1. TC means turbocharged, so it is overclock
Change Log:
v15:
Rebuild with GT-I9502 CHN KK Opensource from OSRC.
Upgrade KSM (Kernel Samepage Merging) to uksm (Ultra KSM) which has Super quiet CPU usage, Ultra scan speed and High CPU efficiency.
Support init.d.
Lower CPU frequencies presented in previous versions, voltage options coming soon.
GPU tweak presented in previous versions.
STweaks cueerntly unsupported, coming soon.
mDNIe and Sound Control coming soon.
AOSP support coming soon.
v14:
Upgrade kernel to 3.4.10
Implement AES-ARM and SHA1-ARM crypto algorithm
Rollback selinux related script to v11
v13:
Rebuilt source tree from HNC6 source.
Most features kept
INT, MIF, MEMIO settings removed, these should not be touched
Should be much better than v12
Fixed video bug for AOSP, I think it is fixed
Upgraded AOSP initramfs, may fix the modem/signal problem
Set ro.secure and ro.adb.secure to 0
Camera lag? Less.
Upgraded busybox
v12:
I don't want to talk about it, this version is totally a rubbish
v11:
STweaks: Added Chinese UI, works on Chinese system, when the language is set to other ones, English UI will show. An templete is provided for more translations.
STweaks: Added boost mode in the Misc tab. The boost mode is found when the news of Samsung cheating on benchmark softwares came out. When a benchmark software is detacted running, the boost mode will be on to allow higher temprature and faster CPU scaling. Simply turn on this mode will not provide any visable change, it should be used with CPU, GPU, INT, MIF clock operations.
STweaks: Added control for Internal, Memory Interface and Memory I/O.
STweaks: Added a button to switch the USB mode to Mass Storage Mode, which is classical mode before GingerBread got out dated.
STweaks: Added a CPU wake lock switch.
STweaks: Added instructiuon of Sound Control being not available on models other than I9500.
STweaks: Added instruction of GPU voltage control being not available on non-tc versions.
Kernel: Added a odin mode. Now we can reboot to download mode with "adb reboot odin". The original commands still work.
v10f1:
initial build for XDA users.
Q&A:
I did not reserve a post for this section, so I will put the Q&A here in the OP.
Q: Which package should I use? A: boot is what you need. recovery is just a side product.
Q: Which version I should use? A: Please the "File name instruction" section in the OP, you will find the answer.
Q: Do I need to wipe the data after I flash? A: Well I don't think you need, but due to some report, wiping data can solve certain problems after flashing this kernel. So whatever you like, please backup data before you flash or wipe.
Q: Which rom does this kernel support? A: I can't tell, please refer to the File name instruction section, if you rom is not mentioned there, it is not supported?
Q: Does this support MIUI? A: Official MIUI is based on touchwiz 4.2.2. So please refer to Q2,3,4.
Q: There is no OC in tc version. A: In the init.rc there is a script limiting the CPU frequency to 1.6GHz, so you should use STweaks to unlock it. Please open /sys/devices/system/cpu/cpu0/cpufreq/UV_uV_table, if there is 2000 1900 1800 and 1700, then there is OC, just unlock it.
Q: Some app FC? A: Usually FCs are not due to the kernel, check the rom first, and settings etc, the kernel should be the last reason, cause it just provide the bridge between the system hal and hardware. Report the fc, I will take a look, but I can not say I can fix it.
Q: Battery life? A: It is due to your habit, just like driving a car, a Toyota Prius can use 10L gas if driven by somebody like Michael Schumacher. As my test, due to my habit with non tc version, it is better than stock.
Q: Do I need STweaks to run the kernel? A: The kernel can run without it, but with it you can have more options.
Q: STweaks shows "unextected error"? A: This situation usually happens at the first time STweaks starts, it is OK. Just go on using STweaks.
Q: STweaks FCs. A: Well this sometimes is due to the kernel, sometimes. Here is something you can do: Wipe the STweaks' data, remove /data/.maxfour and /data/.adamax, check the superuser software and give STweaks root access. And yes you need root access. At last, use normal version.
Q: Auto root? A: Use the CWM zip package. And I would take it out soon. Sometimes it breaks root.
Q: Not actually auto-root with v13? A: Yes, v13 will put a wizard like app which will lead you download SuperSU, only when your rom is not rooted.
Q: Conservative governor stock at certain frequency? A: Don't use it, only ondemand governor is optimized for 5410 with big.little cores.
Q: Can you add something? You must do something? Please do something? A: I take advice, but not demand. The reason is simple: I make this kernel due to my interests, not purchase orders. I am not funded for doing this. If the advice is good, I'd take it. If it is just a personal preference, I have to consider it.
Q: Got very low volume of sound? A: Use stweaks, I9500 has wolfson sound control.
Q: Video color is not correct, got blur faces. A: v13 should have this issue fixed.
Q: No internal storage access permission. A: I will make a workaroung later. For now, remount it with rw option through adb.
Q: Random reboot. A: Well, it exists, I admit. I don't know why. I will look for the reason.
Q: After flashing, the phone won't boot. A: Well, I can't guarantee that this kernel works everywhere. And please check if you are using the correct version.
Q: When is your next release? A: I don't know either.
Q: I flashed, it doesn't work. A: Well, it does not work. I don't know why cause it just don't work. I only answer information-rich questions. Questions like this is only a waster of your keyboard, your time and your data traffic. Please at least tell me which version and what rom you are using.
Q: Anything asked above. A: I will keep silence. Other people may insult for this.
Q: Why don't you answer/respond our questions? A: I am a employee, husband, father and son of someone other than XDA and you.

I kept the feature, so it should show up in STweaks on I9500. I am using 9502 which does not have the feature so I can not test it. When I compile for 9500, sound control is enabled.

Well it is hard to say. If you use the normal version, it should be battery friendly. The tc version is overclocked. Due to my 3DMark result, the overclock version maxied out the First and Second stage tests.

Some Proposals
1. Auto Install Stweaks
2. Clearly describe CPU Options which one for big cores and which for little cores
3. Don't lock GPU Frequency at 532MHz as i see by default ... maybe more relaxed 177-532 settings?
4. SELinux is set to Permissive by default ... maybe set as Disabled?
and maybe some very useful Insecure version please?
ro.secure=0
ro.adb.secure=0
(computer translation)
Hi, I already flashed Adam Kernel on my S4. Can I simply flash this Kernel on recovery or do I need to do something else?

If it is in Adam kernel, then it is here. There is a screen tab in STweaks.
Hi,
I have installed Android 5 (tried both Resurrection Remix and Cyanogenmod 12) to my N7100.
At the beginning, a couple of weeks all works perfectly.
However afterwards everything gradually starts to slow down a lot. I mean everything. Opening apps, browsing, facebook, I even have to wait for a couple of seconds for the keyboard to appear when I clock to type in any field.
I have ofcourse restarted the phone, tried clearing cache (regular one and Dalvik) but nothing helps.
I can do factory reset and reinstall any of the OS-es from above but after a couple of weeks the same will start happening.
Has anyone experienced the same, any ideas?
Thx
Nope......try a stock rom
yes me too, this happened to me on every aosp based rom
Nope. I have a custom ROM already 2 months and it goes perfect.
Try with another rom.

Are you on stock kernel or custom kernel ?

How can I check that? I don't remember changing the kernel explicitly. Just installing the custom ROM as per usual instructions.
Install Agni kernel.
Use pegasus governor
CFQ as scheduler for both types of memory
Set LMK minfree to VERY AGGRESSIVE.
Sometimes cleanup your multitasking.
I have exactly the same on CM 12.1 Android version 5.1.1
Specs: CM-version: 12.1-20150904-UNOFFICIAL-n7100
Android version 5.1.1
Smallband version: N7100XXDMF1
kernel version: 3.0.31-CM-g21d0478
I use No-frills CPU Control, with these:
- Govenor = pegasusq
- I/O scheduler = cfq
I do use Foldermount and apps2sd because of the memory shortage on device. Free storage memory is about 1Gb.
Clean up multitasking? You mean long-click on Home and then remove all apps there? I do that on a regular basis
It would be great if someone finally has a good solution to this.

I set it in the agni kernel manager (I already recommended you to use that kernel) ...
But if you are on a stock kernel, you can try some utilities on play store, just search for "minfree"... maybe they're old, but should work.
*** This kernel is now end-of-life, not supported and developed anymore !!! ***
Hi all,
some of you know me from the other OnePlus or Samsung devices areas, where I provide my kernels already for more than three years to OnePlus 3, 2, one and X, Galaxy S5, S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other, good existing kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
Compatibility
Important: This kernel is only meant to be compatible with official OnePlus OOS and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
To add: An open beta (aka community build) is NOT an official build supported here. If you use a community build and have issues, don't complain or even report. I am not merging any kernel changes from open betas into my kernels !!
Important notes
When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
This kernel is ONLY compatible to OxygenOs stock, nothing else !!!
If you are using a custom rom that bases on OxygenOs, it might work. However, if it does not work, do not expect me to do tweak to make the kernel running with your favorite rom. I would not do it - my one and only reference is OxygenOs stock.
It is not supposed to be compatible to CM, HydrogenOS etc.
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Installation
Read the install instructions in the support section on the Boeffla Site.
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app (outdated at the moment).
Click here to learn about using the config app (outdated at the moment).
I will refuse to give support if you do any undervolting/overclocking and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.
Change logs

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the OnePlus kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
a CAF based kernel
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the kernel only if you are running a compatible rom !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.4.21 or higher for the OnePlus 3T Boeffla Kernels.
Donation
If you like my work, feel free to donate: Donation-Link
If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.
Source code
All sources can be found in my Github repository: http://github.com/andip71
Credits to developers
Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:
* ZaneZam
* Grarak
* Yank555
* Hardcore
* Chainfire
* AndreiLux
* Netarchy
* Gokhanmoral
* Simone201
* Mialwe
* Entropy512
* Faux
* Harunjo
* FranciscoFranco
* Ak
* Osm0sis
... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!

*** As always - Flash on our own risk! ***
Make sure you flash the correct version depending on your firmware version!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.
Cheers and enjoy

After jumping from kernel to kernel (since there are many more kernel devs here than on the OP2) with various minor niggles, finally back to the one I feel fits my needs best. This release brings me relief, as now I don't have to go kernel hopping again, and I think Boeffla provides the best support of all. No bugs so far, multirom boot menu works, everything runs great.
Out of curiosity, is the kernel systemless? (Can I revert to stock by just flashing stock boot.img from latest ROM zip?) I ask because flashing the entire stock ROM takes a long time, and the TWRP loading time is also long.
Also, ext4 tweaks is not hidden for me and is enabled when a profile is reset to default settings. I'm on the default filesystems. (f2fs data, ext4 everything else)
Should I leave ext4 tweaks on or off?
PS: I was probably the first person to like and subscribe to this thread. (within 5 minutes of thread creation)
Edit: Flashable stock kernels? Perfect, thank you @Lord Boeffla ! Does it revert any custom kernel to stock kernel?
Been with Boeffla since S3 and via OPO this will be my third phone with the kernel.
Thanks!

This is not possible on OOS in a clean way.
The kernel comes with modules which are placed in /system/lib/modules too.
So only flashing stock boot.img would not replace the kernel modules by stock ones. So it is only a "half-good" solution.
But, as most of the time, I have a solution for you
Look here: http://boeffla.de/index.php/downloads/downloads-general
Flashable stock kernels for the 3T, which also include the modules.
Guess this is what you need.

This is something I might need to correct in the app then. Leave them off, there is no ext4 anymore on /data volue with stock OOS (but the f**inkg f2fs).
I will look into that over the next days then.
EDIT: Just tried it - cannot replicate that. Maybe your /data partition is indeed formatted in ext4???
(you can check by firing the following command in a terminal: mount | grep data)

I reopened the app, and ext4 tweaks was off. But when I click on reset profile settings, it turns on. But on reopening again, it turns off automatically every time, so I guess it's working fine. Yes I'm sure I'm on f2fs.

Yep, and also means, your data partition is not formatted with f2fs (my op3t came with /data on f2fs)... lucky you. I love ext4 much more, I even consider reformatting /data with ext4 soon, hehe.
Andi
Ok guys, evening hours here in Germany.
I am off for today. If you have any questions, you can also move over and read in the OP3 thread. The devices are - concerning my kernel - 99,99% the same.
So you would most probably find all answers to your questions already there.
Tomorrow I will catch up again.

I'm sure I'm on f2fs. Even TWRP says I'm on f2fs. 3T comes stock with f2fs. This is the output of mount | grep data, but since I'm using magisk I think the output has many partitions and I can't make sense of it.
I think the ext4 tweaks toggle is working fine since it reverts to off automatically when the app is restarted. Thanks!
Here is the output: https://hastebin.com/iwokiramek.hs
Welcome to the 3t Lord Boeffla.. Enjoyed having your kernels and support on the s5 when I was running that phone.. Look forward to the same here..

No. OOS 4 has not yet been officially released and no kernel source has been released.
christmas is here since andi is our santa.
welcome to the 3T world.
loyalists like me have been waiting for you perhaps since the device was launched.
glad OnePlus and XDA did such an awesome thing to distribute devices to devs.
been following your work for a while now.
your kernel turned my OpO into a beast.
just flashed onto my 3T.
will report issues as and when(and if) I can find them.
cheers
Glad to see you here Andy!
finally you will develope on 3T:good:
Glad to see you here Andi:victory:
I use your kernel since Galaxy S3, also flashed it on my opo and my wife's opt.
:good: Now the kernel it's running very well on my new op3t.
Im new to lg g3 first im on lineage and looking for good kernel and some settings between battery-performance (with more balance to battery) what do you recomand guys? (Need and settings some screen shots will be beautifull) ohh lg g3 d855
I recommend you gamma kernel (v50) with the MM/N AOSP rom of your choice. use kernel adiutor for settings.

It depends on what you want. If you havent done the thermal mod, limit cpu to 2ghz max, or even less. Try undervolting it also, see how low you can go before it crashes. Also using noop as scheduler might (in rare cases, such as benchmarks) give noticeably better performance (2800 with bfq and 3250 with noop on antutu io score)
Tnx again i will test more
After some play with some roms , yes i love lineage its smooth but camera ...... this is with stock kernel , now im just flashing between Fulmics (great battery , i have some lag /heating in my games) , and Clean rom (im in love use with extra debloat its what i need but lags /heating). all rom used stock or with other kernels , still i try to configure a kernel like a pro for heating issue and lag but failed , now on lineage the heat its not there (or its very low) and the lag its 0 , still waiting for someone to give me some tips for setting kernel on fulmics or better clean rom , if lineage kernel it can do this why rest no ?
