Before we dive into the detailed guide on how to fix no root after flashing Magisk patched boot.img below, do keep in mind that there is no universal fix for this issue and as such, you may have to try the different methods we have explained below until you find what works. This website or its authors will not be responsible if you damage your device while trying to acquire root, so, please make sure you understand what you’re doing.

1. Mismatch Firmware Build Number and Boot.img Version

The first and most common reason why a lot of users face the issue of no root access after patching their device boot.img with Magisk is due to mismatched firmware build number and boot.img version. A lot of Android users who encounter this issue are unaware that they need the boot.img of the exact firmware build version on their device. I made this clear when I wrote an article on how to root Tecno Pouvoir 2 in the past.

For Magisk patch to work correctly, you should use the boot.img of the same firmware build that currently running on your device. You can check your device build number in your device about phone section and search for the particular firmware online. However, if you can’t find your device firmware build, you can as well extract your full firmware from your MediaTek device using the recent article I published How To Extract Your Stock Firmware from Your Android Device. Guides on how to get the firmware on other SoCs will be published soon.

Once you have the correct boot.img that matches your currents firmware build number, go over the patching process again with Magisk and flash the patched boot.img when it’s done. This is most like the case for many and should fix the no root after you’ve flashed Magisk patch boot.img problem.

2. Use Correct Fastboot Commands to flash Magisk Pactched boot.img

Rooting Android devices got more complicated with Android 8.0 when Google first introduced new types of partitions (A-only and A/B partitions). Flashing custom binaries has become even more challenging for some and the reason most likely is because you are using Fastboot commands meant for a single partition device (a-only devices) for a device with a dual partition (a/b devices).

Devices using a/b partitions requires that you flash the Magisk patched boot.img on both partitions for it to work properly. You can first confirm the type of partition your device uses with the Treble info app which can be downloaded from the Google Play Store. Once you have confirmed the type of partition your device uses, then, use the Fastboot commands below with respect to your device partition.

For A-only partition

For A/B partition

If you’ve tried the first and second methods and still have no luck with root access on your device, then try using the last method below. Although the first and second methods will solve most of the issues of no root after flashing Magisk patched boot.img newer Android versions have also made rooting harder so you might have to try it if you’re running the latest version of Android.

3. Use Magisk Canary

Like I mentioned above, newer Android versions have also made rooting more challenging. While Magisk has worked pretty fine for many users and older Android versions, the stable build has been reported to cause some issues on Android 11. The workaround for this is the Magisk Canary build (or beta). If after patching your boot.img with the stable Magisk build you don’t have root access, then try again using the Canary build.
