Like the title says here its a Magisk Patched Kernel for the S20 Ultra 5G G988B exynos Variant.

Since the S20 needs Canary Magisk and latest Canary Magisk Manager have problems with Patch images (Manager Crashes) i patched the boot.img manually


Soon i will make a custom kernel too. so means i will then convert this thread to the one for my Custom Kernel but for the moment it will be used for the Stock Patched Kernel.

Tomorrow i will add S20 5G and S20+ 5G kernels too


How to install:

1. Enable Developer Settings
2. Enter Developer Settings
3. Enable Oem unlock
4. Reboot in download mode and unlock the bootloader (boot with button combo in download mode and not with adb or recovery!)
5. Bootup the phone and setup it without accounts (Make sure the phone is connected to the internet or prenormal will be triggeret)
6. Reboot again in download mode and flash the tar with the kernel with ODIN.
7. Reboot in recovery mode and make a factory reset / wipe
8. Bootup again the phone and setup it again. this time with accounts when you want and make again sure the phone is connected to the internet over the simcard or wifi!
9. Install the latest Magisk Manager Canary done


Download: From My Synology NAS

@geiti94

Thx.

What do you mean with this "boot with button combo in download mode and not with adb or recovery" ?

What firmware version is this kernel from? (just to make sure there wont be any compatibility issue)

Also is there any guide how exactly should I flash the tar and the kernel with ODIN?

Sorry for the noob questions i rooted Samsung phone longtime ago, but I want to root my S20U as soon as possible because in order to root i must wipe so its good to do it when the phone is new.

I installed the liboemcrypto.so disabler magisk module to see netflix, prime video etc.

Is this step mandatory?

Yes it is since flashing a patched kernel breaks encryption

Since there is no good backup solution when the phone is not rooted, does the Samsung Cloud Backup work after that? If you have any other backup solution then please, share
Oh and since OTA are not working when we apply root, can I apply those updates with odin without flashing the kernel again?

Thank you so much!
@dragsterman
key combo for download mode is: Hold Volume up + Volume down and plug in your PC. You need to turn off your phone first.
Flash in odin via "AP".

Ok I am backing up everything to Samsung Cloud & Google, hard copy of internal storage and will test that baby.
Is there any tool that downloads only the OTA or do I have to always download a complete new firmware?
We always had to format data with TWRP in order to get rid of the encryption. Is the stock wipe enough?

encryption stays here since works with magisk only. only after twrp gets an update for logical partition is then again needed to format data etc. but that will take a while
