As of my last knowledge update in January 2023, the process of rooting a Samsung Galaxy S21 with TWRP (Team Win Recovery Project) might involve several steps. Please note that rooting your device can void its warranty and potentially cause problems if not done correctly. It’s crucial to understand the risks and be aware that this information might become outdated as new software versions are released.

Here is a general guideline on how to root a Samsung Galaxy S21 using TWRP. Please be aware that this process might vary depending on the device’s model and software version:

Prerequisites:

1. Backup: Ensure all your data is backed up, as the rooting process might lead to data loss.
2. Charge: Make sure your device has enough battery to avoid unexpected shutdowns during the process.
3. Enable Developer Options: Go to Settings > About phone > Tap ‘Build number’ 7 times to unlock Developer options.

Steps:

1. Download Necessary Files:

   • Download and install Samsung USB drivers on your computer.
   • Download Odin, TWRP image for your specific device model, and the appropriate SuperSU or Magisk (root management tools) zip files onto your computer.

2. Boot into Download Mode:

   • Power off your Galaxy S21.
   • Press and hold the Volume Down + Power buttons simultaneously.
   • When prompted, press the Volume Up button to enter Download Mode.

3. Flash TWRP Recovery:

   • Open Odin on your computer.
   • Connect your Galaxy S21 to the computer using a USB cable.
   • Check if Odin detects your device (it should show a blue indicator).
   • Click on AP/PDA and select the TWRP image file.
   • Uncheck the ‘Auto Reboot’ option in Odin.
   • Click ‘Start’ to flash TWRP.

4. Boot into TWRP Recovery:

   • Once Odin shows ‘PASS’, immediately boot into TWRP by holding Volume Up + Power + Bixby buttons until the device boots into TWRP.

5. Root Your Device:

   • In TWRP, select ‘Install’ and then choose the SuperSU or Magisk zip file.
   • Swipe to confirm the flash.
   • Reboot your device.

6. Verify Root Access:

   • After the device restarts, check for root access using a root checker app available on the Play Store.

Please note that the steps provided here are a general guideline and may not be specific to the current software version of the Samsung Galaxy S21. The process might differ or change due to software updates or security patches released by Samsung. It’s important to search for the most recent and detailed instructions specific to your device’s model and the current Android version to ensure a successful root. Always proceed with caution and be aware of the risks involved in rooting your device.
