Yes it works

Just a quick question: Does this kernel work with the lastest nightly version?

yess, it works



Sep 18, 2020
Does anyone know if these kernels are still a good idea to run with a (lets say) Android 11 like LineageOS18 or so?
Especially considering that adjusting these kernels might get tricky by now.

But thank you KastenTop, for finding it.

    Hi guys,

    I want to present my kernel for the Samsung Galaxy S3, that allows you to overclock up to 2 GHz. This kernel is based on the official Boeffla kernel for CM14. Although the official Boeffla kernel supports CM14.0 and CM14.1, my kernel supports CM14.1 only, because CM14.0 for the SGS3 isn't supported by the CM team anymore. It may run on CM14.0 as well, but please don't report any errors if you use it with CM14.0 or any other OS than CM14.1.

    Feature list:
    - Every feature from official Boeffla-Kernel (6.1 final)
    - Support for Synapse (partial) and Boeffla Config (fully)
    - CPU overclocking up to 2 GHz
    - CPU: 100MHz step added to save power
    - Faster boot process due to some internal improvements
    - 3 new governors added (adaptive, conservative, interactive)
    - CPU voltage can be chosen between 600mV and 1600mV
    - full F2FS support (backported from Linux 3.19)
    - Charging current can be set up to 2.1 Amps
    - Battery percentage never reaches 0%, so the phone won't turn off at low battery
    - No overcharge anymore due to an internal improvement
    - Early suspend adjustable up to 5000ms
    - more undervolting profiles for the GPU
    - much lower brightness can be set than on stock kernel; the display will be almost black on lowest brightness level (maximum possible brightness stays the same)
    - Configurable kernel logger (turning kernel logger off is not stable on CM and LOS)
    - compiled using GCC 7.2.1 by Linaro (Thanks to ZaneZam for publishing the kernel-specific GCC-6-code; this works with GCC 7 as well!)

    For configuration I recommend Boeffla Config.
    You can use your old config you had using the official Boeffla-Kernel, but this may lead to minor problems. So I'd recommend to reset Boeffla Config before you flash my kernel. If you already use my kernel and just upgrading it you can use the old config without any problems.

    WARNING!!! Nobody except you can and will be responsible for a damaged or bricked phone due to my kernel. It's very unlikely that my kernel harms your phone, but it's not impossible.

    Have fun using my kernel and feel free to ask questions about it!

    fixed the LED driver to properly provide the given settings in Boeffla Config and Synapse
    fixed some voltages to get a cooler CPU
    Will you continue supporting S3 users on Oreo 8.0 ?
    I wish that you continue working on our lovely boeffla kernel to support us on 8.0
    That's will be great News if you do that :good:
    I can't definetly say it, but I plan to do so, but please don't ask for ETA's or something else about this until my first build for Android 8.0 is out.
    This may be one reason why most kernel devs don't support systems which are tweaked by Xposed.
    Apart from that, I've finished the new version of my kernel.
    Hi guys,
    due to a crash of the BIOS of my computer I won't be able to compile any new versions of my kernel until I have this issue fixed. Please be patient for the next update.
