I also have 2 Magisk modules to go with my kernel.

physwizz debloat module v2
(Added a70 changes)
With physwizz-2 app

Magisk module to debloat any Samsung phone to remove all the apps that slow down the phone

To debloat:
Install the module from Magisk and reboot.
To rebloat:
delete the module in Magisk and reboot

wizzROM Creator module v2

for all Samsung a-series phones

Turn any stock or custom OneUI into a QwizzROM or RwizzROM

OneUI 2.0 will become QwizzROM
OneUI 3.1 will become RwizzROM

Debloated ROM with Extras

Extras:
Battery charge limit
Clean Master
ES file explorer
HKtweaks
SimpleReboot
Root Explorer
Zarchiver
physwizz-2

Make sure your OneUI ROM iis running befote you start
Installation
1 Backup system from recovery
2 Install the creator from Magisk
3 Reboot
4 Enjoy



Name your wizzROM (optional)

1. Use a root explorer to copy and paste system/build.prop to new location
2. Edit build.prop like this

ro.build.display.id=<your-name>

3. Use zarchiver to paste the new build.prop into the system folder inside wizzROM-creator.zip
4. Install wizzROM-creator.zip

sideload in lineage recovery ?
also do we need flash dm veriety thing?

can you provide details more specific if you dont mind....
what recovery do we need

You don't need dmverity. It is only for preventing encrypted data.
As far as i know you don't need lineage recovery but I'll confirm with my testers.
I have a127f and I have twrp

Thumbs up for the work
Working on mine
A217F/DS
Lineage Os 18.1
Rooted

Can you do something on gpu ?..
There is some fps gain..by the way and I like this kernel..
Now I can jump in bootcamp..in PUBG/BGMI
In Duo

When I work out how to do the GPU in my a127f I'll also do it on you a21s.

what version of twrp are you using with the a21f? and where do i get it? and it works fine?

I don't have a217f.
I have a127f.
TWRP for a217f is being developed here https://t.me/joinchat/19IDHssAXUxjZTI1

Okay thanks yes n meant to say a217f. Im looking for a working TWRP for sm-a217f

Yes,
It's now working for a217f

 

[AvanGLiT]

Yes?

Yes, it's working on SM-a217M, thank you so much for your effort .

But I encountered a problem, every time I boot up the phone, this message shows up (I can't print): "There's an internal problem with your device. Contact your manufacturer for details."

Also, can you fix the CPU clock to 2.21Ghz for a217M? Or enable it to modifying up to 1.58Ghz? Because my phone always keeps it at 1.58GHz or sometimes at 1.84Ghz, rarely at 2.21Ghz, and it does not increase more than that (1.58Ghz) manually using HKtweaks or 3C CPU or whatever overclocking app. I can only change the governors or decrease the clock. Thank you

1. that error message is normal.
2. To force it up to the highest you have to use Hktweaks to set the minimum values to maximum.
I have a127f .
My benchmarks are below

Thank you, I tried that but unfortunately did not work, the cpu always drops keeping at 1.58Ghz or 1.84Ghz.

But I found that changing some values from config_chipset.json and config_vendor.json files at "/vendor/etc" to 100%, it keeps the CPU stable at 2,21Ghz as well the GPU.

This file schedules performance for some apps and 'occasions', like if I scroll down photos from Galery the CPU drops to 1.4Ghz, and if I close, the CPU goes back to 1.58Ghz. So that was the problem. Changing some values to 100% fixed that, now I'm able to control the clock normally.

 

[NuzzaimStark]

tell me how do you change which app?

 

[AvanGLiT]

tell me how do you change which app?

Root Explorer with its own text editor. I just changed the "Value" : "xxx" to "Value" : "100%" of CPUMinFreq, CPUMaxFreq and GPUMinFreq.

For example: the "Hint": "GALLERY_SCROLL", changes/drops the frequency of CPU and GPU when you scroll your pictures down or up, if you change to 100% of each value, the frequencies will not drop. So you will expect more performance scrolling your pictures.

Can you run a benchmark on geekbench 5?
