    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.

    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.​

    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.

    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

    @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

    Hi,

    I was able to install magisk. In the end, I want to install exposed framework. In the TWRP mode, whenever I try to install, I get an error.
    -Mounting /system and /vendor read-write mount: can't find /system in /proc/mounts
    !Failed: /system could not be mounted

    In the end, it says "Updating partition details" .. done. Can you please help me in resolving this error.

    Hello, is there any way to re-enable encryption after TWRP installation? No matter, FBE or FDE. It says "not fully working" and I see only not working at all, maybe I am doing something wrong?
