I'm on Lineage 14.1 Android 7.1.2 and when I flash the latest version of this kernel, I dont get the option to select S2W in the aroma installer - I only get the option for D2TW. I can enable it with Kernel Adiutor App but it does not stick on reboot (even with apply on reboot set). Is there a way I can force S2W so it stays when I reboot?

I was able to choose S2W when installing this kernel on Android 6.0.1/LOS13 rom, but cant for my current rom?

Hi, is this most stable kernel?
I have unlocked bootloader, anyone tell me which better version of twrp should i install for this kernel please?

This kernel is dead. You could use basically any version of twrp. Use the latest. I wouldn't use this kernel. Use escrima kernel instead if you're using pie or rom default kernel. Its usually escrima anyway.

Thanks for your reply. I'll use latest twrp version. Also i read nougat roms are faster & with better backup, any suggestions for that?

MM is proabably the fastest. So LOS13 by gismoZ is a great rom with security patch updates and bug fixes if someone find a bug. Probably the best rom on kate/kenzo if you don't mind an outdated interface and outdated os.

LOS14 by gitsdb have the latest security patches and with a good stock kernel. So that's my suggestion if you want to go with nougat. If you want to use a custom kernel with nougat I suggest xceed kernel. There's an open Telegram ground "xceed kernel downloads" where you can find it.

If you feel like going pie I suggest AEX by amol. I'm using it right now and it's almost as good as nougat performance and battery wise there are some kinks though like permissive selinux. AEX runs with escrima kernel which is good too.

Just ask if you've anymore questions. :good:

AOSP you mean? https://forum.xda-developers.com/redmi-note-3/development/rom-aospextended-rom-v6-0-t3878333
I downloaded havoc os, is it similar based on aosp?

I meant AOSP Extended. Amol, the dev is just a real good guy and have been supporting kate/kenzo for a long time. In my opinion AEX is the best pie rom, almost bug free, smooth and a good set of features without bloating the rom. It's been a while since I used Havoc but in my opinion that rom feels too bloated with every feature there is that no one really uses. Also I don't feel like changing roms too often and then AEX is a better bet. :good:

Yes both at based on AOSP. :)

    I am not responsible for bricked devices, dead sd cards, explosions, nuclear wars, alarm applications getting failed, please read the first 3 posts (features, faq, settings) carefully before flashing this kernel to make sure everything goes well with your installation.

    This kernel will focus on quality over quantity, I will add only those features which don't cause instability and really improve performance or battery life of our device. I like to test my changes properly before release and keep stability the topmost priority, I don't guarantee weekly or nightly builds, updates will be given whenever required.

    • Mild stable undervolt for both cpu and gpu
    • Optimizations for better load and power management
    Other Improvements -
    • Sound control for speaker, earphones, mic etc
    • Option to select selinux mode while installing
    • Compiled with aosp 4.9.4 aarch64 toolchain
    • Fsync toggle available, enabled by default
    • Custom vibration intensity control available
    Confirmed working or not working on -
    • Works on all lineage and aosp based nougat roms

    Flashing Instructions -
    • Prefer flashing over your rom's stock kernel for best results
    • Read post #2 for some frequently asked questions
    • Download correct version of Radon kernel
    • Make backup of system, boot in twrp
    • Now, wipe dalvik cache and cache
    • Flash the kernel zip and reboot
    Note - In case the kernel doesn't boot for you, restore your system and boot partition from twrp and you will not lose any data.

    Kernel tuning tips -

    Cpu -
    • Governor: Interactive for all kind of users, select battery/balanced/gaming mode while installing according to your need, balanced and gaming modes are totally smooth but battery mode might have little lags.
    • Users who wish to further push battery backup can try using relaxed cpu governor on small cluster, reducing max frequency of small cluster will also improve battery backup.
    • By default, I use these min cpu frequencies 691Mhz (small cluster) and 883Mhz(big cluster), there is also 400Mhz option but I don't recommend using that since it saves negligible battery.
    • Input boost and touch boost should be kept on by balanced/gaming users, battery biased users can consider turning them off.
    Memory -
    • Adaptive lmk should be enabled by all users
    • Z-RAM 512MB with at least 40 swappiness
    • Z-RAM will increase battery consumption a little bit
    • Keep Z-RAM off if you need extra battery backup
    IO Scheduler -
    • FIOPS for good performance and battery
    • Read ahead at least 512 KB on both internal and external
    Screen -
    • Adjust this yourself, I don't know what you like.
    Gpu -
    • Adreno idler - only battery biased users should keep this on.
    • Adreno boost - gamers or performance biased users should keep this on.
    Misc -
    • Fsync -Enabled for more stability, disabled for more performance.
    • Vibration intensity - I use 60, select whatever you like here.
    Note - All settings are compatible with Radon kernel control.

    Frequently Asked Questions -

    Q ) I like this kernel, can I be a part and contribute to this project ?
    It takes many hours to maintain this kernel, If you are a user then donations are appreciated. If you want to contribute to development then you can create your pull requests on my github or pm me with your patch.
    Q ) I flashed this kernel, what next ? How and where do I configure kernel related settings ?
    Recommended app is Radon kernel control, it offers very easy to use custom profile based tweaking, you may check post #3 for some tuning tips if you like to tune kernel settings yourself.
    Q ) Read mode in miui is not working after flashing this kernel ?
    Xiaomi hasn't provided the opensource code for this feature, so read mode is not going to work on custom kernels, but you can try going into display tab of radon kernel control app and make a custom profile with R,G,B(254,234,195) and saturation 40 for very similar experience to miui read mode.
    Q ) My fingerprint doesn't work, what to do ?
    Kenzo comes with two different sensors, fpc and goodix, all nougat roms have fixed support for both sensors, but if you use miui rom and you have goodix sensor then you might need to flash the patch from post #6196.
    Q ) I flashed this kernel, but I want to return to my stock kernel, how to do that ?
    If you read flashing instructions in first post, you will see that I asked you to make backup of boot and system partitions before flashing my kernel, now you can restore that backup and you will have your stock kernel back. In case you didn't take a backup, just dirty flash your rom zip without wiping data and that will restore stock kernel and modules.
    Q ) How much battery backup does this kernel give ? Will it give me x hours of SOT ?
    The battery backup depends a lot on your usage, like screen brightness, wifi, 3g/4g data. Changing your kernel or rom will not make battery backup double. If you are just wifi user, your device can give 9+ hrs screen on time. Heavy 3G, 4G, Bluetooth users shouldn't expect huge battery backup. Regarding battery consumption when display is off, I normally lose 2% battery for about 8-9 hours of standby, but if you you keep wifi and data off in night, then you should get 0-1% drain per night.
