Hi, sorry if this question has been repeated over and over again.

When new version is released, should i just flash it over the older one or do i have to dirty flash rom again before installing the new one?

Anyway best kernel i've tried on bacon so far (been using this device again after i left it a year in closet :p), though im using zanezam's version. Kudos to both of you!

Hi,

usually you can just dirty flash Boeffla kernel over an older Boeffla kernel, really simple.

It is only important to have once the Lineage Stock kernel installed when you initially install Boeffla. But then it is not required anymore, only if you tried a different custom kernel in between.

Hi, i had downloaded the beta 9 version and had flashed the day you released ,but it still stayed on beta 8. Now after you messaged today i flashed it once more, again with the supersu zip since i thought flashing kernel will mess root, but then it still stayed on 8. I tried again just the kernel and it got updated to latest with root intact. Strange..

Did you flash with the right sequence, as explained in the wiki?

This looks like supersu installer reverted the kernel again every time.

Correct is:
Rom
SuperSu
Boeffla kernel

I thought the right sequence is

Rom
Boeffla Kernel
SuperSu

Because when i had note 2, flashing the kernel before SuperSu always removed the root access.

And now i already had the beta 8 installed so i just install the kernel and SuperSu, but as you said SuperSu reverted the kernel back to old. So just the kernel flash did the work.

Hi thanks for the quick answer. That explains what i needed to know.
Anyway boeffla is the most stable kernel for bacon i think (tried all others), glad to have you as a dev for this device!

It CAN work, but it is not safe (as you have seen).

The Wiki tells quite clearly the correct sequence:

Hi all,

I want to inform you, I am going on a 3.5 weeks holiday to sunny Florida basically right now. I am back Monday, 20th of November again.

This means:
- No kernel or app updates in the next 3.5 weeks
- I am also not reading forums at all, nor will I answer questions here
- Support requests by E-Mail will be answered after my return
- Donation codes will be generated, but maybe with some more delay

Have a good time, enjoy a "flash-free" time... and CU all again soon.

Andi

Flash-free? Speak for yourself, lol. Enjoy your time off! When you're back you'll realize how awesome Oreo is on Bacon and start developing Boeffla for it anyway! Oooh, did I just do that? :silly:
Much love

Hi, can any ine tell me what settings should i keep in Boeffla for a better game performance.? NFS no limits performs well in other kernel., But not in this., It won't even stay open for sometime. It closes itself after a while.
Thanks

I have no advice for you, as I am not gaming myself. But you have read my kernel is in no way a gamer kernel? Just to ensure and set expectations.

Although there is no reason why it should not run in general.

@Lord Boeffla I'm actually using the beta9 Kernel with 20171009 Nightly. Is it good for the latest Nightly release or I've to wait a beta10 for better compatibility?

TY

Hey,

beta9 is still up-to-date. You can use it with latest nightlies.

There were no official LineageOS kernel code changes for ages anymore on Bacon.

    Hi all,

    some of you know me from the Samsung devices area, where I provide my kernels already for more than two years to Galaxy 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 Cyanogenmod / CyanogenOS 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 !!



    Important notes

    1) When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !

    2) Do NOT use TWRP's function to root your device after a clean rom flash!!! The installed supersu version is not up to date and may cause a bootloop with latest COS/CMs kernels !!!


    3) Make sure you flash the correct kernel version, depending on whether you use cm11s stock or genuine cm11, COS13.0, COS12.1, COS12.1.1 or genuine CM13 !!!

    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.
    Saying that, the Boeffla-Sound app in Play Store is not designed to work on the OPO, neither was it developed by me, hence it will never work on the OPO ever. Boeffla-Config is the way to go here !!!



    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.

    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.

    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
    • custom hotplugging algorithms
    • 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 correct kernel depending on whether you are on stock cm11s or genuine cm11 !!!


    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 2.1.48 or higher for the OnePlus One 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
    * Yank555
    * Hardcore
    * Chainfire
    * AndreiLux
    * Netarchy
    * Gokhanmoral
    * Simone201
    * Mialwe
    * Entropy512
    * Faux
    * Harunjo
    * FranciscoFranco
    * Ak

    ... 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 !!!

    Disclaimer

    *** 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

    Some statistics...

    Hi all,

    this morning I decided to take a look at traffic statistics on my web servers and I was really more than surprised, yeah... somehow even "amazed".

    What started with a small and simple project for the Galaxy S3 in October 2012, to just provide one single Boeffla Kernel for Samsung based JB roms, meanwhile grew to a "monster". Currently I provide 12 active kernels for 4 different devices (Galaxy S3, OnePlus One, Tab 10.1 n8000 and n8010), and the statistics meanwhile are going through the roof :)

    Look yourself at the attached web server Webalizer stats (sorry, headings in German due to being on a German hoster).

    The facts to call out:
    • You guys meanwhile create a download traffic of avg. 20 GBytes per day !!!
    • Just in January 2015, so far a total traffic of 228 GBytes for downloads were created.
    • Boeffla-Config app has been auto-updated around 40.000 times this month already
    • Boeffla-Config app has been downloaded manually around 26.000 times this month
    • Samsung Galaxy S3 Kernel in version 7.2 (for Android 4.4.4) has been downloaded 7456 times in January.
    • Samsung Galaxy S3 Kernel in version 6.2 (for Android 4.4.2) has been downloaded 4846 times in January.
    • CM12 alpha kernel for S3 also 4652 downloads
    • Galaxy S3 Android 4.3 kernel on 4027 downloads
    • Then first OnePlus One kernel for CM12 with 3052 downloads
    ... and so on.

    All in all, my various kernels have been download approx. 28.000 times only in January so far.

    Guys, this is AMAZING!!!

    Seems like the Boeffla-Kernels are a quite successful and liked by their users. Although it was never planned to reach that size, ever.

    I just want to say THANK YOU for the trust and confidence in me. In the past 2,5 years and hopefully also the same in the future.

    (and I hope, my web hoster is not trying to get rid of me due to that huge traffic)

    Cheers

    New betas...

    Hi all,

    ok, finally new kernels for you with the unofficial new touch drivers (as they seem very good) and a new zzmoove governor (credits to ZaneZam).

    Please note, the kernels are for CM12.1, CM12s/COS12 and for CM11s. However, I have not tested the CM11s kernel at all, so you will see how it behaves.

    Here we go:

    CM12.1 -- Version 4.0-beta18
    Note: Only for CM nightlies of 14.05. or newer (and custom roms having these new changes in)
    01.06.2015

    • New, unofficial, selective touch screen drivers implemented (Gerrit) - this should fix the touch screen issues for many without draining battery
    • zzmoove governor updated to version 1.0-beta7 - stability improvements and hotplugging optimisations (credits to ZaneZam)
    • New zzmoove governor profile "relax" added, aiming to avoid audio stutters during screen off
    • Replaced kernel-internal busybox by a new version
    • Ramdisk updated to official CM12.1 version of 01.06.15

    CM12s/COS12 -- Version
    3.0-beta10
    01.06.2015

    • New, unofficial, selective touch screen drivers implemented (Gerrit) - this should fix the touch screen issues for many without draining battery
    • zzmoove governor updated to version 1.0-beta7 - stability improvements and hotplugging optimisations (credits to ZaneZam)
    • New zzmoove governor profile "relax" added, aiming to avoid audio stutters during screen off
    • Replaced kernel-internal busybox by a new version

    CM11s -- Version
    2.10-beta1 stable (untested by me !!!)
    01.06.2015

    • New, unofficial, selective touch screen drivers implemented (Gerrit) - this should fix the touch screen issues for many without draining battery
    • zzmoove governor updated to version 1.0-beta7 - stability improvements and hotplugging optimisations (credits to ZaneZam)
    • New zzmoove governor profile "relax" added, aiming to avoid audio stutters during screen off
    • Replaced kernel-internal busybox by a new version

    Update for all kernels...

    Hi all,

    after I returned back from my business trip yesterday night, I now provide you kernel updates for all three active kernels: CM12, CM11 and CM11s.

    CM12 - Version 3.0-beta6
    23.01.2015

    • Reported issue about not working hotplug profiles (e.g. restricting to 2 cores only etc.) seems to be resolved, could not replicate it anymore
    • Updated with latest >50 CM kernel commits for CM12 until 23.01.15 (-> c2b66bcd5), those are mainly camera related by the way
    • Removed a few optimisation commits for stability purposes
    • Ramdisk updated to official nightly of of 22.01.15


    CM11 - Version 2.1 stable
    23.01.2015


    • Updated with latest CM kernel commits for CM11 until 23.01.15 (-> f0a2e1d)
    • Removed a few optimisation commits for stability purposes

    CM11s - Version 2.1 stable
    23.01.2015

    • Removed a few optimisation commits for stability purposes
    Enjoy
