Edit 2021/03/18: I have added Magisk boot image for Max Lumi v. 3.1. Updating a rooted Max Lumi over the air is working. After installing a (full) firmware update you have to flash the patched boot image again.

Steps to install:
[1] Current firmware version of Max Lumi is 3.1. Attached bootimage is not suitable for other Boox devices!
[2] Download and install Magisk Manager on Max Lumi. Edit: current name is Magisk.
[3] Do you have installed adb, fastboot and USB drivers on your computer? 15 seconds ADB installer for Windows.
[4] Enable usb debugging on your Max Lumi. See Settings/Applications. Plug Max Lumi into your computer, accept fingerprint message and run in command line to check connection.
adb devices
[5] start a bootloader session
adb reboot bootloader
Your Max Lumi will reboot and you will see the Onyx logo on screen. That's normal.
[5] The bootloader of Max Lumi is unlocked by default. That's nice. Thanks Onyx. You can check it with:
fastboot flashing unlock
[6] flash patched bootimage
fastboot flash boot your_patched_boot.img
Then your Max Lumi reboots by itself. Otherwise type:
fastboot reboot
[7] Start Magisk Manager and you use "direct install" method to root permanently.

Sample terminal session:
C:\Users\Leo\Desktop\Max Lumi>adb devices
List of devices attached
e3b2a8ed        device

C:\Users\Leo\Desktop\Max Lumi>adb reboot bootloader

C:\Users\Leo\Desktop\Max Lumi>fastboot flashing unlock
FAILED (remote:         Device already : unlocked!)
finished. total time: 0.004s

C:\Users\Leo\Desktop\Max Lumi>fastboot boot Max_Lumi_v3.0.Magisk.21.2.boot.img
downloading 'boot.img'...
OKAY [  0.276s]
OKAY [  0.002s]
finished. total time: 0.301s

C:\Users\Leo\Desktop\Max Lumi>
Further reading:
It's a non standard installation of Magisk, because Max Lumi has a bootimage without ramdisk but loads this ramdisk when it is patched to bootimage.
decrypt Boox Update Upx, to get a boot image for your Boox device of encrypted firmware update.

Booting into recovery mode: (just in case you need it)
[1] With pressed home button connect your turned off Max Lumi with USB C to a charger.
[2] You get the Onyx splash boot screen.
[3] Release the home button.
[4] LED next to power button is blue. Recovery mode starts.
[5] Select option in recovery mode with home button. Execute option with power button.

#1 Magisk Manager on rooted Max Lumi with AdAway app in Split Screen mode
#2 & #3 Magisk Direct Install
Hi. I have just a couple of questions:
1-Can I root an Onyx device with Android 6 (Onyx Note first generation) in the same way?
2-At the moment I use Kingroot to root my device and then I use Supersu-Me to switch to SuperSu: what are advantages if I use Magisk to do it?
Thank you for your help
