I couldn't get it to work in Android 12. It enters in a bootloop. I flashed Android 12 stock firmware, rebooted, turned ADB on and flashed TWRP just like OP said... Can someone help me?

Hallo,
this doesnt work for me
I used the latest version and it boots up twrp
But if i want to do something i get pure errors, every Partition cant be mounten. /data cant be mount and all the others
I followed the steps exactly.
Even i cant wipe data after multidisabler, the same, Storages cant be mounted.

Doesnt this work on latest Android Version?then how to install Dr ketans neueste ROM?

    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 S21 G991B/N.

    Download & Guide:
    1. Unlock your bootloader.
    2. Download S21: o1s.
    3. Reboot to download mode
    4. Put the TWRP TAR for your device with Odin in the AP slot, vbmeta_disabled_R.tar in USERDATA slot and click start.
    5. Reboot to recovery via recovery key combo (Vol up + power + USB connected).
    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.​
    - Go back to Wipe > Format Data > type yes.​
    - Reboot to recovery.​
    7. Flash magisk apk in twrp.
    8. Reboot to system, Enjoy.

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

    Hi guys..

    Will this work for model G991B/DS?
    Yes

    @afaneh92 The recovery supports flashing Magisk APK out-of-the-box?

    So, no need to rename the .apk to .zip anymore?
    You can flash apk
    I'm kinda casual, with haptic feedback not working do you mean the vibration motor in the phone stops working completely, or? I don't know what encryption not working means either.
    I saw the same issues for the S20 FE.

    Looking at both forums closely currently as I'm deciding which phone to buy dependent on which phone will have a better root experience.
    Vibration not working in twrp only, read more.
    Will this have to be done everytime there is a firmware update?? Or like other devices we can keep twrp and magisk when updating..
    I currently have S20 which I dont have twrp on but can update new firmware and just reboot to odin after flashing new firmware and just flash patched boot.img and all is good. Will the S21 be the same
    Yes need to redo every step.
