Good idea to read the F.A.Q before installing
Q : Will it work on A51,M30,A70 or any other device ?
A : Clearly, No.
Q : How to root ?
A : The image comes pre-rooted with the latest Magisk 22. Boot normally and it should boot rooted.
Note: GSI Users must use the phh superuser app instead of magisk manager.
Q : How to update magisk version?
A : You can't. Wait for me to build a new kernel with the latest magisk
Q : Bootloops after updating magisk version from magisk manager
A : Told ya. It's my job to update the magisk in kernel. Just reflash the kernel and you should boot fine.
Q : How to flash?
A : Flash the zip normally. Additionally, if you just flashed stock, use multidisabler + format data.
Q : Camera working?
A : Yes
Q : Phone rebooting to splash screen after installation
A : Make sure you have the latest BL and CP installed from CUBC update Also flash multidisabler, just in case.
Q : Stuck at Samsung bootanimation after formatting data and reboot
A : Reboot manually with button combo
Q : How is battery backup / performance ?
A : After thorough testing I'd say battery backup is good with great performance
Q : Will it work on xyz rom ?
A : Normally it should. But if you can't, update your software and try again.
Q : Will it void warranty ?
A : Yes. Flashing any image not signed by samsung requires an unlocked bootloader and it voids warranty, depanding as per your country restrictions.
Q : Will I receive OTA from samsung or secure folder, Samsung Pay work ?
A : No!​

How to pass Safetynet ?
Before I tell you that, remove all the SafetyNet-related modules that you might have installed and reboot.
If you have used the MagiskHide props module and changed your device fingerprint/have enabled device simulation Make sure you reset your props to default & disable any of the device simulations. Revert any changes that you may have made with it.
Finally, install this module from Magisk
Click to download
To pass SafetyNet, you need to enable magisk hide and hide magisk manager so that 3rd party apps cannot detect the package.
This module bare is enough to pass SafetyNet
However, if the changes you have made are hard to revert and you cannot pass SafetyNet with it, I think a clean flash of the ROM + this module would be a good start. Again, do not use MagiskHide Props with android 9 fingerprints. It really isn't a good idea. If you use the above module, you'll rock with the stock fingerprints

I am sure it does, for me and possibly everyone else. Would suggest you to update. Most likely your drivers are outdated making them incompatible with the kernel. Good luck

Samsung Smart switch not working after installing this kernel, any solution to get it back ?

---

Does this work on stock rom?

---

Sir I know you from j7 nxt . You have ALWAYS been a legend. I wonder if you could make this kernel available for a51 ?

---

Hi
Is it possible to overclock a205f display to 68-75 hz?

Update: Refined Kernel V2.0
RefinedKernel V2 is here! Finally, after putting a lot of work into this project, I can say you are going to be amazed by the outcome. For the first time in the community, I present you a hassle free-rooting with the latest kernel. Now the user needs not to remember the hectic button combinations to boot with and without root. It is as easy as it used to be. Just boot to the system normally and I can assure you will be rooted out-of-the-box. This also means that booting to recovery just got easier and we can use the appropriate commands to do the right thing. At last, I'd like to add, please don't try to update the magisk version yourself. Now that it's implemented in the kernel, you cannot modify it. It's my job now to keep my users updated with the latest stable version of magisk.
Refined Kernel v2.0 - 18.03.2021
- Supports Android 11 (OneUI/GSI)
- Rebased the kernel to CUBC source
- Pre-rooted with magisk v22
- Boots to system directly with root(No button combination needed)
- Tons of optimizations for smooth performance & great battery
- Disabled various debug logs in background
- Completely removed Samsung based securities
- Wakelock blocker
- Added the maple IO scheduler
- Enabled the available CPU governors, IO Schedulers
- Wireguard support
- Better deep sleep
- Power Efficient Workqueue
- fsync support (Disabled by default)
- Removed hard-enforce selinux
- TCP size to 64K for better speed
- NTFS Support
- Disabled FIFS
- Comes with TWRP 3.4.0
- DriveDroid support
- CRC checking disabled
And other features from the previous release
1. Ensure you have the latest bootloader and modem from CUBC update
2. Download the appropriate kernel zip (OneUI/GSI)
3. Flash the zip with TWRP
4. Reboot to system (Not Recovery !)
Note: If you are coming from stock rom (Official Binary) then you must format data in TWRP and flash multidisabler to remove encryption and Samsung securities in the system itself. Otherwise you may find incorrect available space in internal memory or your userdata may keep getting encrypted on every reboot.
