Patching Guidance:

Installation Guide (Only For Bootloader UL On Q/10 & Now Upgrading)

Factory Reset from settings. If already on the earlier version and rooted, this will allow you to boot to stock recovery, else, you will get a "Error!!" screen of the recovery. (Remember, Magisk for Samsung patches to recovery mode, and thus format data is needed).

Boot to recovery. (Guide Link)

adb reboot download

Format/Wipe data and cache one after the other in Recovery mode. Do, this at-least 2-3 times. This ensures, any remnants are removed

ENSURE to MOUNT /SYSTEM

Boot to download/fastboot/bootloader from there

Open Odin and ensure to untick/uncheck "auto reboot" under options

You can tick/check "re-partition" if you like, however, with Q and the current Odin version it is not needed

Under the "AP", select the Magisk Patched file (M30_XQ 20200824 Magisk Patched(6CTH5).tar)

** Now connect the phone with USB while still in download mode

The COM port will show the device connected

Click Start, and ideally in 3 minutes, it will get flashed. (Ensure Auto-Reboot is unchecked)

Once successful, remove it from usb cable connector

Press Volume Down and Power key together for 7-8 seconds

The screen will vibrate and go black

That very instant, while holding the power button, also press the volume up button

You will feel another vibration. Let go of power button, while still holding the volume up button

This will reboot to stock recovery

Format/Wipe data and cache one after the other in Recovery mode

Reboot to system (will take around 10-12 minutes, so be patient)

Once everything is setup, go to

settings>developer options>uncheck auto-update

Also uncheck "auto download over wifi/data" under software & updates in settings

Copy files over MagiskManager apk file (latest canary files attached here) and install it

Once installed launch and enjoy root features

IMPORTANT

One only needs the MagiskManager.apk and the ODIN ZIP files from the attachments here. I have given rest of files just for the sake of anyone wanting to read through its binaries. Please use only ODIN and MagiskManager.apk files.
