Help with Note 5 boot loop

I was attempting to root my Galaxy Note 5, and accidentally flashed the SpaceX kernel which was for the android 5 version, when I was on android 6. Dumb mistake, but now my phone isn't booting. I assume if I have the proper kernel I can flash it back, but I can't find this. I can still access recovery, just not system boot.

Can someone help me get this fixed please?
