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+ G996B/N.

Download & Guide:
1. Unlock your bootloader.
2. Download S21+: t2s.
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.

have you disabled encryption? and logs?
Yes multi 2x times wipe data Yes reboot. Ive acces to whole data. How to make log for you that will help you? And like i was saying first backup super partition for me was succesful. Then i delete it and trying make new backup, and starts in middle of work. I Discovery that is "optics" folder So now i make backups without it (4Mb data inside optics"

Hi, i just updated my S21+ Exynos to android 12. It's rooted with magisk and just installed the last TWRP.
But I'm gettin 255 error when trying to backup data. I've been told that TWRP can't backup android 12 data, is that true? There is any workaround? And any hope for this to be fixed?

Try to check recovery log and delete the folders causing the error
