How to create your own:
This method does not need root, and also does not require a custom recovery.
Download Magisk Manager from here
Press Install > Install > Patch Boot Image File, and select your stock boot image file
Magisk Manager will now patch your boot image, and store it in [Internal Storage]/MagiskManager/patched_boot.img
Flash the patched boot image to your device and reboot. Voilà!

Hi there.
I'm trying to update my phone to Oreo January patch, I'm currently with December patch that is such bugged. Well as I read I have to download the update and before installing it I have to uninstall Magisk restoring the boot image and then after the update installing the boot image of Magisk again, I tried to flash the ROM with MiFlash saving the user data to solve it, and I did it but all my data just gone I don't know why, well the thing is that I updated, I thought, and then I flashed the patched boot image of Magisk in fastboot mode, and there is where I missed the boot image and I lost the update maybe...
Is there an option to flash JUST the boot image and not all the ROM or put the stock boot image just into a Magisk folder to have it?
If you install magisk using magisk manager, it will backup your original boot image and when you uninstall magisk, it will restore your boot image.
If you want to manually flash your boot image, you can do that in fastboot mode.
Code:
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
You can get your stock boot image from the rom files that you used in MiFlash tool. (boot image is inside that rom folder/zip file)
In miflash, you need to make sure you select the"save user data" option in the lower right corner. The file it will use is the "flash all except storage" file. Then, don't flash magisk. Update, them worry about rooting.

Hey, thanks for your answer, I manually flashed my boot image to update my phone to January Update but it didn't work, when I try to install the update it says "Couldn't install the update, try again later"
Any idea to solve this?
the kernel is based on Bluesplash by cojocar.andrei -twrp version 3.1
made some fixes on twrp and the kernel and the boot.img. and security issues on some partions,
cache in twrp is disabled in this version,
flash boot.img and then recovery,
this is beta not 100% tested. flash on your own risk. tested and works on marchmellow.
fastboot flash recovery recovery.img
fastboot flash boot boot.img

My friend give me a Huawei Mediapad with lastest stock rom EMUI 5.1.3 and Android 7.0 installed. I want to root it with Magisk. After successful unlock bootloader, flash twrp, than I tried to flash Magisk 25.2 under twrp. The flash process output some permission denied error with /data/... path, but return success result. After reboot, it enter the boot loop. Then, I boot to recovery and try to uninstall Magisk, but not success. I need to recover it by flash the original boot.img from fastboot to make it boot again. Next, I tried to patch the boot.img under Magisk Manager. This time, I got the patched boot.img and flash it again in fastboot mode. It's the same result. All the patched boot.img by using differnt patch options are not boot successfully. Any procedures to make root successul on this rom?
