Did you have a copy of the Magisk-ed boot on your desktop?
If so, you should try booting (not flashing) that first, because it's painless.
Go to fastboot:
Code:
C:\>fastboot boot Magisk-whatever
Do you have any other images?
I might be able to turn your Magisk-ed image into a recovery.
If so, post it and give me a link.
Edit: I'm lazy (and my internet sucks). Here is an update for the Leaf which you will be needing:
http://firmware-us.boox.com/3c1a22db...b0b/update.upx
It's about 1.3GB (probably).
Then you'll need this to decrypt it:

Fortunately, somebody got the encryption strings already.
Now, you've got a big zip file.
Does it have a boot image in it? A recovery image in it?
You're going to need this in any case because you have to do a manual update.
