While in recovery mode enter :
mfastboot oem fb_mode_clear
That will solve that booting issue.
Sir, it's not correct. I've installed 5 times using this recovery latest version but nothing happened. I could see the xxx NoLimits branding in build number and even in magisk it shows but found no app installed in app drawer. It was like nothing ...
I try to flash twrp installer zip with flashfire but it can't find the boot image when flashfire wants to flash it. I need the stock boot to do that?

So with the updated SuperSu zip file I can flash TWRP 3.1.1 from this thread? The TWRP installer? Can flash with FlashFire?
Yes you can flash it with either of them.
