Yoga Tab 2 Pro - 1380F --> Magisk possible?

Hi Everybody,

did one of you manage to get Magisk running on your 1380F?
I'm on latest Firmware / ROM and rooted by temporary booting CWM and flashing SuperSU, like in the tutorials over here.
If I flash Magisk, no matter if pre-rooted or not, via Magisk Manager or CWM --> The tablet recognises that the boot image was manipulated, doesn't boot anymore.
It jumps directly to the stock recovery...

Any ideas?

Thanks in Advance,

McK
