Brief information and benefits of TWRP recovery

TWRP (Team Win Recovery Project) is an open source community development project. Flashing TWRP allows you to install any firmware on your device, boot your smartphone, modify zip files for settings, Xposed modules for settings, root and uproot with one click. You can also make a full backup of Nandroid and restore it later, flash the image file with one click, remove bloatware, overclock and underclock. With TWRP, you can easily erase, cache and clear data after flashing an image file to reflect changes and correct minor errors caused by caching.

To install TWRP, your Samsung Galaxy S21+ Plus 5G SM-G996B/N phone must have an unlocked bootloader. This means that you first need to unlock the bootloader to root the device, and also perform a configuration.

Denial: Although AndroidWeblog.com covers everything very clearly so that our readers get exactly what they want, there is always a small chance that major problems may arise from the steps listed here. It is therefore in the user’s interest to carry out the steps very carefully in order to avoid accidents with the device.

Rooting and flashing a custom ROM will definitely invalidate your device’s warranty and AndroidWeblog.com cannot be held responsible in any way for invalid warranties or tinkered with devices.


Check the model number, which should be as follows:

  • Samsung Galaxy S21 Plus [Models : SM-G996B, SM-G996N] Android 11, One UI 3.1 [Exynos chip] [device code: t2s]
  • Country/Region : International/World

You should make sure you read the disclaimer carefully before you routinely use your phone and agree to continue taking the risk.

The phone must be 70% charged, otherwise complications may occur during the experiment. Why take the risk of fully loading it.

If you plan to root your phone or install a custom ROM, it’s a good idea to back up your phone. Back up all your media like photos, videos and everything on your PC, as well as your contacts to the cloud.

Steps to flash / install TWRP 3.5.0 on Samsung Galaxy S21+ Plus 5G SM-G996B/N (t2s) Android 11, Single UI 3.1

Supported: Samsung Galaxy S21+ Plus 5G Exynos Variant Models: SM-G996B, SM-G996N with Android 11, One UI 3.1)

Step one: First, enable USB debugging on your device. To enable USB debugging, simply enter the developer setting. Go to Settings>About Phone> and press the house number 7-8 times until Developer on appears. Once the developer options are enabled, you can go back to Settings> Developer Options> Enable USB debugging.

Step two: Let’s assume that you have already downloaded the latest versions of Odin and TWRP Recovery for your device from the sample area above. If the latest version of Odin does not work on your device or if you are experiencing problems, simply download the correct version of Odin.

Step three: Make sure you have already downloaded TWRP Recovery for your Samsung device. Then unzip the compressed Odin file on your computer and install the latest Samsung USB drivers on your computer.

Step four: When the device is turned off, press the ‘Power+Volume Down+Home’ buttons simultaneously and the device will enter the boot mode. If this key combination does not work for your device, search Google for this key combination for your device.

Fifth step. Now connect your Samsung device to your computer using a USB cable. Next, navigate to the folder where the Odin files were extracted and right-click on the Odin executable, then click Run as Administrator.

Step six: The interface should display something like ‘ID:COM’, and check the interface carefully below.

Seventh step: Note the ID:COM field and the empty field below it, which turns blue once the device has been detected. The device should be detected if the correct drivers are installed on the computer.

Step 8: Then just click on AP, then go to the firmware archive, find the .tar.md5 file and select it after clicking on AP.

Message: There is a PIT zone in the re zone. Do not place files in the PIT section and make sure repartitioning is not enabled. Check the box and place a check next to Automatic restart and F. Time reset.


Step 9: Once the TWRP file (.img) is uploaded to the AP area and the vbmeta_disabled_R.tar / multidisabler file is uploaded to USERDATA, the flash or installation process can begin. Be careful not to touch the USB cable while it is flashing.

Step 10: If all goes well, you will see a green PASS or RESET message at the end, indicating that the TWRP firmware process for your device has been successfully completed and that it now has TWRP Recovery. At this point the device will automatically reboot, don’t panic, this is normal.

Step 11: Now we have to disable the encryption. Go to Advanced > Terminal, type : Multidisciplinary. In the back cases, it may be necessary to reboot the multi-disk adapter. If the system indicates that there is free space on the device, it will try to resize the creator and ask you to restart the multidisc adapter. If this is the case, re-enter: multi-discretion. When the operation is complete, the message Done appears on the screen. Now go back to Clear > Format data > type yes. Now just reboot to recover.

You can now disconnect the device from the computer.

Procedure for Rooting Samsung Galaxy S21+ plus 5G SM-G996B/N (t2s) to Android 11, Single UI 3.1 – Install Magisk or SuperSU.

Make sure you have downloaded SuperSU or Magisk Manager (link in the required section of this article). Then continue with the next steps.

Message: You can use Magisk Manager or Super SU, but only one, so choose wisely. Go to Magisk Manager if you are not sure.

Step one: Transfer the downloaded SuperSU or Magisk Manager file to the internal memory / SD card of your Samsung Galaxy S21+ Plus 5G SM-G996B/N smartphone.

Step two: Just get started on the recovery. You can also make a ROM backup via the TWRP interface. However, I recommend that you make a backup copy of the ROM. Because if the process fails, you can flash the ROM.

Step three: Click Install, then navigate to the SuperSU.zip or magisk.zip file and drag the firmware confirmation file (located at the bottom of the screen). The Magisk/SuperSU flash process has started and will take a few seconds. Then select Reboot to restart the system.

Congratulations, you have now rooted the Samsung Galaxy S21+ Plus 5G SM-G996B/N and the TWRP is on. Now you can install Xposed Framework and customize your smartphone as you like. If you want to check it, you can download and check the root status through the Root Checker application.
