The mid-rangers from Samsung have appealed to the masses and in some style. In this regard, the M21 is no different either. In countries like India, it has always occupied among the top spot in the buyer’s preference list. When you are getting a device that tick marks all the required necessities and OneUI as the underlying OS skin without burning a hole in your pockets, then the device’s rise to fame is no hidden secret.
However, for the tech enthusiasts, there were a few doubts. This is because the device comes with Exynos as the underlying chipset. And if we were to line Snapdragon, MTK, and Exynos on the ease of development, there’s no doubt who would occupy the last spot. Furthermore, being a majorly closed source makes it quite difficult for the modding community.
But once Samsung released the source code for this device, everything picked up the pace. In this regard, the device was recently blessed with the TWRP Recovery [Read: How to Install TWRP Recovery on Samsung Galaxy M21]. Well, the availability of this custom recovery automatically opens the gate to a plethora of tweaks. These include the likes of creating Nandroid backup, flashing ZIP and IMG files, and the likes.
Then you could also flash the Magisk ZIP Installer file and root your device. However, there were a few users who don’t wish to install TWRP on their device but still wants to root it. If you also echo these thoughts, then you have come to the right place. Given here are the detailed steps to root your Samsung Galaxy M21 device without using TWRP Recovery.

While there are quite a few other alternatives as well (SamMobile), I usually prefer this only. So refer to our detailed guide on How to Download Samsung Stock Firmware/ROM via Frija Tool.
As for this device, type in the below-given information in the Frija Tool and hit the Download button situated at the bottom left: [Just make sure to change the CSC code as per your country accordingly before downloading the firmware]:

- Once the firmware file for your device is downloaded, extract it to a convenient location on your PC.
- You should now get the following five files in .tar.md5 format:
AP, BL, CP, CSC, and HOME_CSC
- Out of these five files, we will use the AP file to patch it via Magisk and then flash it via Odin.
STEP 4: Patch Galaxy M21 AP File via Magisk
Now that you have the AP file extracted from the firmware, transfer it to your device’s internal storage. After this, install the Magisk Manager app on your device. Then launch the app and check if it says YES or NO next to Ramdisk. Remember the answer as it will be used at the end to boot your device to the rooted OS.
After this, refer to our detailed guide on how to: How to Patch Samsung AP Firmware via Magisk. The shorter explanation is as follows: Launch the Magisk Manager app on your device.

- After this, click ‘CP‘ and load the CP firmware file.
- Then click ‘CSC‘ and load the CSC firmware file (the normal CSC file, not the Home CSC file).
- While we only need to flash the Patched AP firmware file, but it is never recommended to flash it alone. You should always flash this file along with other firmware files, always!
