Im on default, pre-sets sre in system/etc/init/hw/kernel.sh.
1. Can I ask why ur default settings disabled powerefficient workqueues?

2. Can I ask rationale for sched_util governor as default, as opposed to energy_step?

2a. Why kernel.sh default shows sched_util, but fresh install of thundertweaks shows energy_step by default? (see screenshot)

3. I posted a screenshot of my kernel.sh. Can help verify that this is indeed your default settings that get u the awesome battery life u are experiencing?

4. Was thundertweaks automatically installed as a system app? Or after flashing u manually went to the zip file, look for thundertweaks apk and install as user app? Could this have an impact on settings persistence?(Just trying to troubleshoot stuff in previous post)

5. After installing fresh default thundertweaks, is is necesscary to apply on boot every category if I don't change any of the settings? (sorry if this is a beginner questions, but I'm just drilling down to fundamentals in my troubleshooting process)

To my untrained eye there's more to optimize, but just curious about ur rationale for choosing these settings

--

I also notice u use Franco kernel manager together with thundertweaks. Do they clash?

Ad 1 bcose stock kernel has not and mine too..you can turn on in ttweaks or kefnel.sh
Ad 2 bcose is not good optimized for samsung ems energy system and energy step gives me best battery and perf then schedutil.
Ad 2a # in line means do not run this line so you see is not in use any schedutil lines
Ad 3 try and do it your self, read uncle google
Ad 4 on S20 N20 is install auto, if not so you can use ttweaks from zip or TS News Channel no matter is system or user app
Ad 5 after instal if you dont change anything so no sense select apply on boot. Only if you change something.

Franco i have only for look which settings are in STune section. I dont use it for any settings.

When rooting the S20 on EUL7 firmware ONEUI 4 you have to patch the boot.img with magisk and then flash it using ODIN.
I read that magisk is included in this KERNEL but will I have to flash the magisk-patched boot.img with odin again to gain root?

Jaké TWRP pro aplikaci kernelu použít? Mám android 12. Pokud nelze použít TWRP v 7zip jsem přejmenoval kernel ze zip na tar, mohu instalovat přes ODIN? Moc díky za odpověd.

Translated by GT: What TWRP to use for a kernel application? I have android 12. If I can't use TWRP in 7zip I renamed the kernel from zip to tar, can I install via ODIN? Thanks a lot for the reply.

Take this. Just flash with Odin. Flash the TS zip with TWRP. Update Magisk, done.

I have the BR 4.0 with the TS kernel 2.0. It works really fine. But now I try to update the TS Kernel 2.0.1. flashing with TWRP. Result was an Bootloop. Does anyone the same problem?

I find the solution. I have updated the TS Kernel without Magisk. Also I think it was a problem with the TS tweak tool. Maybe I have make some settings, which are not compatible with the new Kernel. I deactivated the tool and flash TS with Magisk. Now all works fine:).

Before install any new kernel Mtweaks, TTweaks, hkTweaks must be wiped - restored to default - another way You can get bootloop.

Hi, there is something I don't understand, the changelogs always include stuff that were already in previous versions but then mention "Rest like ..." implying that these changes would be new?
I don't understand what's new and what is not in each version

These are mostly reverts and further changes to previous version. For exp. You may see "modified audio libraries" 2 times in a row, meaning they are further modified.
Or you can see rollbacks from current drivers.
Sometimes it is just the version update, sometimes it is some variable that is changed.

    I have used it since sep.2021 for s20+ and also since s10+. You can read yourself #5 :ROFLMAO:

    That's long enough to say that the kernel on s10+ and 20+ is no different from stock kernel with OneUI4.1

    And since then you have no Thundertweaks settings told us or supported here or released already with settings that the kernel will be better than stock Kernel Samsung

    I have compiled your current kernel on GitHub and it is no different than the kernels you have been releasing latest for 20+here.

    Just don't buy this sh**.... It's not worth it. Also it's not legal to sell a kernel. GPL 🤔😏

    Its sad that i have to pay for kernel. I used it a long time and i was very happy with it. But ok run stock kernel now.
