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 Ultra G998B/N.

Download & Guide:
1. Unlock your bootloader.
2. Download S21 Ultra: p3s.
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.​

Hello everyone, I only have one question, besides the Twrp and the vbmeta_disabled_R.tar do you also need to flash a Multidisabler via Odin? Thank you.

I wish there was a very easy way to patch AP to keep TWRP after a dirty flash manual upgrade.
1.Easiest option - Go with custom ROM (If available)
2.Second easy, modify AP and patch it.
Extract all the contents of AP file - delete recoevry and vbmeta images - Repack as tar (You can use 7zip or similar) - Patch it with magisk
After flashing, straightway go to TWRP - and apply multidisabler before booting device.

This would clear the User data / Accounts also, yeah ?


@afaneh92 _ Bro, I think the existing TWRP doesnt mount Data on the Newest March Security Patch.
I had no issues with the February Firmware.
Could you have a look ?

You asked for dirty flash trick right? If erasing data and acc then it's not dirty flash.
I don't have any issue on March secure patch

What could be causing this issue?
Did a full stock flash as well, and repeated the TWRP process.

    I just want to say thanks to @afaneh92, this guide is superior and every time I decide to reload my phone or setup a new rom I revert to this guide.

    Hello guys, a super great rom finally arrived on S21 Ultra. We will be needing this awesome TWRP. I just wanted to ask if this will work on AUBB firmware? Thanks in advance.
    Yes
    Can someone please share a link to a "safe" odin download?

    I have some old versions that I have been using on my S9.

    I googled for the latest version of ODIN but it seems there are plenty of fake pages and I would prefer to download a legitimate version that would work correctly with the s21.

    Thank you in advance.
    Someone has a logo fix to, unlock the s21 ultra bootloader
    Yes search for it
