What’s new in Magisk v21?

To recap, the previous release (Magisk 20.4) disabled Magisk Hide by default in light of the new hardware-backed SafetyNet attestation, BusyBox standalone mode, and introduced several other minor changes. Before you head over to the download links or instructions, let us take a look at some of the key changes that Magisk v21 brings.

Note: The changes below were originally written for v21.0 and have now been expanded with the new changes in the Magisk v21.4, v21.3, v21.2, and v21.1 updates.

1. Google Pixel 5/4a 5G Support

Up until now, Pixel 5 and Pixel 4a (5G) owners had to resort to Magisk Canary builds for gaining root access.

But now, Magisk 21.1 (and above) has been updated to use Boot Image Header version 3, thus adding support for the Pixel 5 and Pixel 4a 5G. If you’re a developer, the changes in the latest header version have been posted in the official documentation here.

2. Android 11 Support

As you’d know, after months of testing, Google finally announced the stable Android 11 update a few months ago. Several device manufacturers are already begun publishing Android 11 beta builds for their devices, like the OnePlus 8 series. This certainly means that a lot of users are running Android 11 on their phones. For rooting enthusiasts, Magisk has already supported Android 11 on the Canary channel. With v21.0 (and above), Magisk now fully supports Android 11 on the stable channel. The developer has worked pretty hard to re-write a lot of Magisk code from the scratch.

Further, Magisk generally mounts and use the /tmpfs directory to store temporary data. According to the developer, the /sbin sub-directory may no longer be available in Android 11. So, on devices running Android 11, Magisk will automatically create a random folder inside /dev and use it as PATH. Developers could find everything about this change in the official documentation here.

In terms of Android 11 support, Magisk v21 also fixes an issue wherein Magisk was removed after a factory data reset.

2. Redesigned Magisk Manager UI

Earlier last year, developer John Wu showcased a preview of a completely new design of the Magisk Manager application, courtesy of Viktor De Pasquale (@diareuse). For months, users running Magisk Canary have had the privilege to enjoy this new UI. With Magisk Manager v8.0.2, the newly redesigned UI is now available for users on the stable channel as well.

Starting with the design itself, the old hamburger-based slide-out menu has been completely removed. It has been replaced with a minimal navigation bar towards the bottom end of the app. Items throughout the app’s interface are now showed in form of cards.

Individual sections of the app are rearranged for quicker access. For example, Magisk Hide (when enabled) is now shown under the ‘Superuser’ section instead of having its own dedicated section. Also in the old UI, downloading and managing modules were done from their own individual sections. With the new UI in Magisk Manager v8.0.2, you now have a unified ‘Modules’ section that allows you to manage (install, uninstall, and disable) and download Magisk modules from the same screen.

The new Magisk Manager also incorporates eight different color accent schemes and the ability to force light or dark theme modes.

Themes in Magisk Manager v8.0.0

Personally, we are not a huge fan of the card-based design in general, but Magisk Manager adapts it so well that we have no other choice but to adore it. Overall, this new user interface takes quite a huge leap over the previous one, in terms of both design and usability.

3. Safe Mode Detection

Boot loops caused by modules due to incompatibility is a common issue that a lot of users face. Up until now, users could either use TWRP or ADB to remove the rogue Magisk module(s) to fix the problem.

Developer John Wu was surely well aware of the issue and has brought us a simple solution. From Magisk 21.0 onwards, you could simply boot your Android device into Safe Mode. Magisk will detect Safe Mode and automatically disable all the Magisk modules. You could just reboot into the OS after this and the boot loop will be fixed.

4. New SELinux Policy Setup on Android 8.0+

The SELinux security has been hardened with a completely new policy setup for devices running Android 8.0 Oreo and above. This new policy now keeps the Android Sandbox less compromised, separates the Magisk policy rules from original rules, thus providing better security on devices rooted with Magisk.

5. F2FS Kernel Drivers Fix

Several users reportedly faced bootloop and module instability issues with Magisk v21. These were reported on Github. The issue has been fixed in Magisk v21.4 as developer John Wu was able to find the culprit. A newer Canary build has also been pushed for the respective users.

He pointed out that it was caused due to an F2FS driver bug in the Linux kernel. He further added that this bug only affected a specific Android kernel branch, which was the reason why not all devices were affected by the issue. As for stability issues with Magisk modules, only devices that used the modern F2FS drivers were affected.

So these were the major changes in the Magisk v21 update. For end-users, not a lot has changed except for the first two, i.e. Android 11 support and redesigned Magisk Manager. For developers, there are also some key changes made on how Magisk works. You would like to refer to the new changes in the official documentation here.

How to Install Magisk v21.4 on Android

You can install the latest version of Magisk on your Android device using the following two ways/methods:

  1. By flashing the Magisk installer ZIP file using a custom recovery, such TWRP recovery.
  2. Or, by patching the boot/recovery image in Magisk Manager and then flashing the resultant patched boot image to your phone.

The first method is generally more straightforward and it’s what you should use if you have a custom recovery installed. On the other hand, if a custom recovery like TWRP is not available for your device, or if you don’t want to install a custom recovery at all, then simply follow the second method.

The second method also makes it much easier to install OTA updates on rooted devices using Magisk. All you will need is the stock boot/recovery image for the Android software version/build number currently installed on your device. You can extract these images from the OEM Factory Image or OTA update package (instructions here), try downloading it from firmware.mobi, or look up your device’s rooting guide on our website.

Before you install, it is strongly recommended to take a full backup of all your data before you begin installing Magisk. If any issues arise, this backup should help your restore all your data.

The following tutorial will help you install Magisk v21.4 using the aforementioned methods. We suggest you go through the instructions and familiarize yourself with the procedure before you start performing it.
