Copy apkm21 file to your device storage




Once you have downloaded the apkm21 file, you need to copy it to your device storage. You can use a USB cable, Bluetooth, or Wi-Fi to transfer the file from your computer or another device. You can also download the file directly on your device using a browser or a downloader app.


Install Magisk app on your device




To use apkm21, you need to have Magisk app installed on your device. Magisk app is the interface that allows you to manage Magisk settings, modules, and root permissions. You can download Magisk app from its official website or from XDA Developers. You need to install Magisk app as a normal apk file.


Patch apkm21 file with Magisk app


After installing Magisk app, you need to patch the apkm21 file with it. To do this, you need to open Magisk app and tap on the "Install" button. Then, select the option "Select and Patch a File". This will allow you to browse your device storage and select the apkm21 file that you want to patch. Magisk app will then patch the file and save it as a new file with the extension ".magisk.apk".


Flash patched apkm21 file with custom recovery




The final step is to flash the patched apkm21 file with a custom recovery. A custom recovery is a software that allows you to perform advanced operations on your device, such as installing, backing up, or restoring custom ROMs. You need to have a custom recovery installed on your device before flashing the apkm21 file. Some of the popular custom recoveries are TWRP, OrangeFox, and PitchBlack. You can find the instructions on how to install a custom recovery for your device on XDA Developers or other forums.


To flash the apkm21 file, you need to boot your device into the custom recovery mode. This can be done by holding down certain buttons while powering on your device, or by using an app like Reboot to Recovery. Once you are in the custom recovery mode, you need to select the option "Install" and then navigate to the location where you saved the patched apkm21 file. Tap on the file and swipe to confirm the installation. Wait for the process to finish and then reboot your device.


Benefits of using apkm21




Using apkm21 has some benefits that make it a desirable option for Android users who want to root their devices and use Magisk. Here are some of them:


Apkm21 allows you to root your device without modifying the system partition




One of the main advantages of using apkm21 is that it allows you to root your device without modifying the system partition. This means that you can keep your device's original software intact, while gaining root access and customizing your device with Magisk modules. This also makes it easier to unroot your device if you want to, by simply uninstalling Magisk app and flashing the original apkm21 file.


Apkm21 enables you to use Magisk modules and hide root from apps




Another benefit of using apkm21 is that it enables you to use Magisk modules and hide root from apps. Magisk modules are add-ons that enhance your device's functionality and performance. You can find hundreds of Magisk modules on Magisk app or on XDA Developers. Some of the popular Magisk modules are YouTube Vanced, which allows you to watch YouTube videos without ads and with background playback; AdAway, which blocks ads on your device; and EdXposed, which allows you to use Xposed Framework modules on Android 10 and above.


Apkm21 also allows you to hide root from apps that detect it, such as banking apps or games. Some apps may not work properly or may block your access if they detect that your device is rooted. To avoid this, you can use Magisk app's "Magisk Hide" feature, which lets you hide root from selected apps.


Apkm21 supports OTA updates and seamless system updates




A third benefit of using apkm21 is that it supports OTA updates and seamless system updates. OTA updates are updates that are delivered over-the-air by your device's manufacturer or carrier. Seamless system updates are updates that are applied in the background without interrupting your usage. Both types of updates are important for keeping your device secure and up-to-date.


Using apkm21 does not interfere with these updates, as it does not modify the system partition. You can receive and install OTA updates and seamless system updates without losing root or Magisk modules. However, you may need to re-patch and re-flash the apkm21 file after each update, as it may be overwritten by the update.


Risks of using apkm21




While using apkm21 has some benefits, it also has some risks that you should be aware of before using it. Here are some of them:


Apkm21 may not work on some devices or Android versions




One of the risks of using apkm21 is that it may not work on some devices or Android versions. Apkm21 is a relatively new file format, and it may not be compatible with all devices or Android versions. Some devices may have different bootloaders or partitions that prevent apkm21 from working. Some Android versions may have different security features or restrictions that prevent apkm21 from working. You should check the compatibility of apkm21 with your device and Android version before using it.


Apkm21 may cause bootloops or brick your device if done incorrectly




Another risk of using apkm21 is that it may cause bootloops or brick your device if done incorrectly. A bootloop is a situation where your device keeps restarting without reaching the home screen. A brick is a situation where your device becomes unusable and cannot be fixed by normal means. Both situations can be caused by flashing a corrupted or incompatible apkm21 file, or by making a mistake during the flashing process. To avoid this, you should always backup your device before flashing any file, and follow the instructions carefully. You should also have a way to restore your device in case something goes wrong, such as using a PC tool like Odin or Fastboot.


Apkm21 may void your warranty or violate the terms of service of some apps




A third risk of using apkm21 is that it may void your warranty or violate the terms of service of some apps. Some device manufacturers or carriers may not honor your warranty if they detect that you have rooted your device or modified its software. Some apps may also ban your account or restrict your access if they detect that you have rooted your device or used Magisk modules. To avoid this, you should check the warranty policy and the terms of service of your device and the apps that you use before using apkm21. You should also use Magisk app's "Magisk Hide" feature to hide root from apps that detect it.


Conclusion




Apkm21 is a file extension for Android apps that allows you to install Magisk on your device without modifying the system partition. It has some benefits, such as allowing you to root your device, use Magisk modules, and hide root from apps. It also has some risks, such as not working on some devices or Android versions, causing bootloops or brick your device, and voiding your warranty or violating the terms of service of some apps. You should weigh the pros and cons of using apkm21 before deciding to use it.


If you want to learn more about apkm21, you can visit its official website or its XDA Developers thread. You can also find apkm21 files for various apps on websites like APKMirror or APKPure. However, make sure that you download them from trusted sources and follow the instructions carefully.
