Model G981U.
I have unlocked OEM, disabled AVB, wiped the phone as it required, then it rebooted into system automatically.
Then I put Roms & Gapp installation zips into the phone internal storage , turned off and flashed twrp 3.5 in the download mode. And Odin showed 'successful '.
However it still boots up to Android Rec. I have tried it several times. What am I doing wrong ? Please guide. Thanks.

And here comes a new problem: when I finished flashing vbmeta_disabled.tar , the device didn't reboot to recovery automatically but booted to system instead. So did I fail to disable AVB? How can I fix it please?
Appreciate any help. Thanks.

You need to be quick and boot to twrp after flash, once device reboot and screen goes black press vol up and power.

    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.
    Note: My TWRP builds are free I take no money or selling them, The new builds support US devices unlocked before 9 november or added upon request.

    Supported Models:
    Galaxy S20 Ultra G9880, G988N, G988U, G988U1 and G988W.
    Galaxy S20 plus G9860, G986N, G986U, G986U1 and G986W.
    Galaxy S20 G9810, G981N, G981U, G981U1 and G981W.

    US/Canada bootloader unlock thread:
    here

    Download & Guide:
    1. Unlock your bootloader.
    2. Download S20: x1q, S20+: y2q or S20 Ultra z3q.
    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:
    - 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.

    Is it ok to NOT use the multi disabler?. I mean I flashed it already but just saying.
    This thread has the details of what all it helps with.

    Thanks @afaneh92. For others' help, if anyone finds it useful, I flashed TWRP on my G986U1 using this sequence:
    • Unlocked bootloader as I described here.
    • Flashed vbmeta from this thread using patched Odin.
    • Flashed TWRP using patched Odin but did not auto-reboot.
    • Rebooted into TWRP using key combination.
    • Format data
    • Flashed multidisabler from OP in TWRP.
    • Format data again, just to be safe.
