Hi my loard!
Thank you for that kernel! By the way - on beta 36/37 zRam doesn't work anymore. Tried everything including 20 config changes of course each with a reboot... till beta 35 it worked.
Thanks again and cheers!

Are you sure you are in the right thread?
This is for the Samsung stock boeffla kernel.

What exactly is your issue with zRam?
Everything was changed by CM with beta35...
Have you read the changelog for it?


  • Change: zRam driver was updated as part of the CM commits - this driver does not work very dynamically anymore, this means:
    • after you change zRam settings in Boeffla-Config you are asked to reboot to make the new settings active
    • when you change profiles with different zRam settings, you also need to reboot to apply the changed zRam settings
    • And yes - I do not like this new driver but it is getting implemented on almost all devices now, so there is no way out really.
Please had over to the right thread as I cannot continue here on a CM kernel.

If you type by hand in a web browser www.boeffla-kernel.de it works.

JB 4.4.4: 7.9

JB 4.4.4: 7.9
kernel support ttl check, but Iptables not support ttl set.

The command cat /proc/net/ip_tables_matches produces a list in which there is ttl, that is our core check the TTL can. But in the list, which gives the command cat /proc/net/ip_tables_targets, no TTL, TTL therefore modify our kernel does not know how.

Who can compile the necessary module? «TARGET_TTL»
net/netfilter/xt_HL.ko

The kernels are EOL, as the thread title says.

No development anymore on them.

So, I'm currently on arter97's back-to-n00t ROM and everything works fine, except it's charging in a very slow rate. This is on every ROM, so I need to flash Boeffla-Kernel to disable the instable powers (or what it's called). Now, after I install the kernel (for 4.4.4 - 7.9), I can't turn on wifi anymore. It disables itsself right afterwards. I don't know if the ROM is compatible with this kernel, but as you named it as an example on the main page, I think it is.

Yes, it is. In fact it was developed for it.

Never had a wifi problem with it.

GPU undervolting

On the last 4 kernel version (maybe more) I can't undervolt my GPU, in undervolt tab I can read "this functionality is not implemented by the used kernel", wich kernel have this function?

Sorry wrong section, my question are for g900f

Ok, you are indeed in the wrong thread.

But to answer: On g900f I never implemented GPU undervolting as it is technically not possible. So it never was the case, and never will be.

    *** NOTE: All kernels are now officially end-of-life (EOL).
    Please do not expect any more updates for them in future, no maintenance and no bugfixing. ***


    Hi all,

    this is the thread about the well-known Boeffla-Kernel for the Samsung Galaxy S3 international.

    Compatibility

    Important: This kernel is only meant to be compatible with official Samsung Stock firmware 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 !!



    Notes:
    Never install it on CM or AOSP based roms!!!

    • Kernel version 5.x are only for Samsung based Jelly Bean 4.3.x roms!!!

    • Kernel version 6.x is only for ported Samsung based Kitkat 4.4.2 roms (e.g. Archiport) !!!

    • Kernel version 7.x is only for ported Samsung based Kitkat 4.4.4 roms (e.g. back-to-n00t) !!!

    • Kernel versions 1-4 are only for Samsung based Jelly Bean 4.1.x roms!!! (no development anymore)

    For the CM Boeffla-Kernel, please go HERE.

    If you have questions to settings, presets, others configuration and wanna share your configuration, head over to the unofficial Boeffla-Config App Config sharing thread:
    http://forum.xda-developers.com/showthread.php?t=2621308

    Support

    First read the FAQ section on the Homepage !!!

    Click here to learn about all possible kernel settings in the config app.
    Click here to learn about using the config app.

    I will refuse to give support if you do any undervolting 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.

    History

    Basically I created Boeffla-Kernel 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. 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 !!!

    This said, I will definitely NEVER implement:

    • dual boot (I do not need it)
    • color "calibration" (I do not like it, but I like the crispy stock colours)
    • real hard overclocking higher than 1600 MHz as this is outside of Exynos specs
    • f2fs - it is known to cause various issues and compatibility problems
    • anything that requires upstreaming of kernel parts to a higher kernel major version
    So do not even ask for it. Everything else I am happy to check and decide.

    Compatibility

    To reiterate it again: This kernel is only for Samsung based Jelly Bean (Android 4.1.x) firmwares. It is not designed to run on AOSP based roms!


    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.


    Donation

    If you like my work, feel free to donate: Donation-Link

    You will receive a personal donation code which unlocks some nice 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:

    * Yank555
    * ZaneZam
    * Hardcore
    * Chainfire
    * Harunjo
    * AndreiLux
    * Netarchy
    * Gokhanmoral
    * Simone201
    * Supercurio
    * Mialwe
    * Entropy512
    * Faux

    ... 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 CWM recovery and safely store your personal data before you flash a new kernel.

    Final round up

    Hi guys,

    also a final round for my S3 Samsung kernels today, which are now considered final.

    Change log is the same for the Samsung JB 4.3, Kitkat 4.4.2 (Archiport) and KitKat 4.4.4 (back-to-n00t).

    • zzmoove governor updated to version 1.0-beta8 - bugfix and cleanup release (credits to ZaneZam)
    • zzmoove governor profile "relax" added (aiming to avoid audio stutters during screen off)
    • TCP optimisation (initial TCP window size)
    • Enabled a bunch additional tcp congestion algorithms that can be selected in Boeffla-Config app (click here and here for more information)
    • Support for latest Boeffla-Config apps to have a better stock settings determination
    • Kernel build process now able to use ccache
    • Internal build script enhancements
    • Internal async kernel start script reverted back to previous approach
    • Replaced kernel-internal busybox by a new version

    Have fun (hopefully)
