On the download page ...
There are 2 versions of c2q; one R one Q. Does it matter?

Stuck on ...
7. Disable encryption!, flash multidisabler-samsung-3.x.zip and format data in twrp and type yes.

Is disabling encryption and installing the multidisabler the same, or is that two steps? Any elaboration would be helpful.

Can't locate zip file. This is what I get whether I select Install Image or Install Zip.
TWRP = twrp-3.5.0_10-1_afaneh92-R-c2q.tar
Running Samsung: 11

Would it be possible to unzip and flash externally with ODIN?

Yes. Seeking to find, I changed the install directory. The External SD was taken from another phone and there are lots of files on it, but none were visible. In addition, I created 2 new copies of the multidisabler and put those in 2 different directories on the External SD. Found the directories, but not the files.

Use adb to push the files to the root directory /

ADB worked. Flashed from TWRP. Done!
However, phone now boots to SAMSUNG screen and after extended pause reboots.
I can get back to TWRP and Download, but currently do not achieve a full boot.

This is pretty slick. With Majisk running in the ROM and TWRP running outside of the ROM; it is kind of like having a military guard inside and outside of your house. Everything is very stable now.

School me on one more thing ... Once a new version of Android comes out; in essence 12. At that point I would need to Odin the Android12, reinstall Majisk, Download and flash TWRP for Android 12, reinstall multidisabler, then reload backup data and apps? This will be the process for every update?

    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    Code:
     * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or your getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    Supported Models:
    Galaxy Note 20 Ultra N9860, N986N, N986U, N986U1 and N986W.

    US/Canada bootloader unlock thread:
    here

    Download & Guide:
    1. Unlock your bootloader.
    2. Download Note 20 Ultra: c2q.
    3. Reboot to download mode and flash vbmeta_disabled.tar in AP slot and reboot. Device will reboot to stock recovery mode prompting you to wipe data so wipe data and reboot to download mode again.
    4. Put the TWRP tar for your device with Odin in the AP slot and click start.
    5. Reboot to recovery via recovery key combo.
    6. Disable encryption:
    Or:
    - Go to Advanced > Terminal, type: multidisabler.​
    If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​
    - Type: multidisabler again. will see - Finished. when done.​
    7. Go back to Wipe > Format Data > type yes.
    8. Reboot to recovery.
    9. Flash magisk apk in twrp.
    10. Reboot to system, Enjoy.

    Note:
    To disable encryption manually:
    You need to replace fileencryption=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom
    To avoid stock recovery restoration manually:
    Rename system/recovery-from-boot.p to recovery-from-boot.p.bak

    Support:
    Live support is available via #twrp on Freenode with your IRC client or just click this link.

    How do I unlock bootloader on sm-n986w? OEM unlock is not in the dev option list
    US/Canada devices has no oem option. Can be unlocked via some services. I cant discuss here in xda because I didn't got approved yet to post. You can try to contact out of xda.

    What's the difference between this and mental? I know his is featured rich.
    Ability to flash system img for gsi etc..
    You still can use fastboot to flash GSI
    Most fixes he took from me and Im not interested in features that can be flashable zips.
