Here is Patched kernel to root N986B Note20 Ultra (N986B_TH3)

Quote:

NOTICE :

Before you move further, make clear that rooting device -
- Your warranty will be void
- Some of functions may not work on rooted device, some function may get back with un rooting, some may never.
- All your data on device will be lost
- Flashing custom binaries may brick (Usually soft but can be hard brick too) your device, so follow it on your own risk!

If you are ready with condition, move further -


A.Preparing Root files

You need to patch file to flash using Odin to root device.
1. Download stock firmware for your device (google search will give you many sites to download it) some common are e.g. Sammobile, Samfirmware tool)
you need to download file according your region and model (Dial *#1234# will give you details of existing firmware, download accordingly)

2. Once you finish download, extract files and keep all files on PC. From extracted files a file with name AP_[device_model_sw_ver].tar.md5 copy to your device.

3.Download Latest Magisk Manager and Install to your device

4.Open Magisk Manager - Magisk (first one) - Install - select to "Select and Patch file" - Navigate file you have copied to device (AP_[device_model_sw_ver].tar.md5)

5.Magisk Manager will patch the whole firmware file and store the output to [Internal Storage]/Download/magisk_patched.tar

6.Copy patched file magisk_patched.tar to Your PC - THIS IS FILE ONE YOU NEED TO FLASH, Now prepare second file.

7.
A.Patching Kernel : This is required only If you want to root device without installing custom recovery (TWRP). In case you want to root + have TWRP then skip this step and move to step B

Open magisk_patched.tar with 7zip and extract/pull boot.img from tar - Copy boot.img to device and patch it using Magisk manager same as you patch AP file in step 4 - Now you will have Magisk_patched.img file in download folder - Copy that file to PC. Rename that magisk_patched.img to boot.img (Name must be exact same). Make sure your PC have 7-zip installed, If not get and install it. Rt click on boot.img and select 7zip - select "add to archive" - select archieve format as 'tar' - and name it Patched_Kernel (it will be like Patched_Kernal.tar). Don't keep space in name. This will create a Odin flashable patched kernel and This is FILE TWO YOU NEED TO FLASH

B.Preparing TWRP :
Download TWRP for your device from Here. Extract recovery.img from TWRP file you have downloaded. Make sure your PC have 7-zip installed, If not get and install it. Rt click on recovery.img and select 7zip - select "add to archive" - select archieve format as 'tar' - and name it TWRP_file (it will be like TWRP_file.tar). Don't keep space in name. This will create a Odin flashable patched kernel and This is FILE TWO YOU NEED TO FLASH

8.Download latest Odin (one is attached to end of this post) and extract to a folder on PC (I recommend on desktop)

Now next step is to modification on device

Unlocking Bootloader

This is a basic step to root device. Go to settings - about phone - Software Information - tap multiple times on "Build number" - This will open developer option.
Now in settings at the end, you will have new option "Developer options" - look for OEM unlocking - Enable it.

(PS : If you don't see this option then you may need to wait up to 7 days or more to appear or may be on some operator you will get it never. Without this option you can not root your device, sorry!)

Once you have enable OEM unlock option, switch off your device and reboot to download mode.
To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable
When device start to download mode,long press volume up to unlock the bootloader. This will wipe your data and automatically reboot

Now let finish setup and again enable developer options (as said above), and confirm that the OEM unlocking option exists and grayed out!
If it is not then you can not root device!

Once you see this option and greyed out, you are ready to flash custom binary and root your device

Installation (Flashing) custom binaries

1. Switch off the device and reboot to download mode (As said earlier) and select volume up to continue

Open Odin as administrator (Odin attached to below this post)

A.Click AP tab of Odin and navigate to magisk patched file (AP file that you have patched with magisk manager) (One you made in above Preparing files, STEP 6)
B.Click on UserData tab of Odin and navigate to Patched kernel (One you made in above Preparing files, STEP 7A) - In case you don't want to install TWRP OR navigate to TWRP file ((One you made in above Preparing files, STEP 7B) In case of you want to install TWRP

3.From Odin option - uncheck Auto Reboot option

4.Now start flashing and wait till it finish. When you see a PASS sign on Odin, disconnect device.

Factory reset

After disconnecting device, keep holding Vol down + Side key to exit from download mode.
Here is very important - when you see device reboot As soon as the screen turns off, immediately press Volume Up + Side Key to boot to recovery partition. continue pressing the volume up button until you see the recovery screen.

In the stock recovery menu, use volume buttons to navigate through menus, and the power button to select the option. Select Wipe data/factory reset to wipe the data of the device.
Select Reboot system now

In case of TWRP, you needs to select WIPE tab - FORMAT DATA - You need to type "yes' to confirm - After this - select REBOOT - REBOOT to recovery - and you have to install two files 1.Magisk zip (2.MultiDisabler (You can get it from TWRP thread) After flashing both - reboot to system

The device will automatically reboot for the first time it boots. This is completely normal and done by design.After the device is booted up, do the usual initial setup. You shall see Magisk Manager in your app drawer; if not, Download Magisk Manager and manually install the APK you downloaded and continue to the next step.

Magisk Manager will ask to do additional setups. Let it do its job and the app will automatically reboot your device. (You must needed to connected to internet)


Important : Once you root device, it is highly recommended to immediately make EFS IMEI backup of device and keep it to safer place other than device itself.

The first link was to show what firmwares are out already for Note 20, meaning the North American and HK Snapdragin are yet to release

Mostly U version is Snapdragon with unlock bootloader and not rootable. Confirm first if you have unlocked bootloader.
Also last 3 digit of firmware is weird. Which device is this? Can you post screenshot of phone info?
