Samsung Galaxy S5 Active - CM12 issues topic

Hey Guys,
I'm trying to get the CM12 klte ROM of the S5 on my S5 Active but I'm having some trouble at one of the steps. Maybe someone can help?

I've followed this guide
wiki.cyanogenmod.org/w/Install_CM_for_klte

I'm got all the way up to step 10 of installing a custom recovery but when I try and boot to recovery using UP VOL/HOME/POWER, it says...

could not do normal boot
odin mode
Product name: SM G870W
Current Binary: custom
System Reset: official
Reactivation Lock (kk): off
knox warranty void: 0x1 (4)
...

It's as if the custom recovery ROM doesn't work or was never loaded although all previous steps indicated that it did.

Any ideas?
