Soft-bricked G00V (Failed rooting attempt)

Heya, so after a failed attempt to root my Samsung Galaxy S5 Verizon (G00V) I soft-bricked it. I have been following a lot of guides on the internet but, so far they haven't worked (I don't know if I didn't have the right software or if I wasn't doing it correctly). I still have access to recovery mode and my PC can detect it. I already have Odin and Samsung USB drivers. If I try to install the stock ROM on Odin I get this:
<ID:0/004> Removed!!
<ID:0/004> Added!!
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..

Next I tried installing the software over SD card from recovery mode, but got this:

Supported API: 3

#MANUAL MODE#
