S4 can't flash back to NB1 from botched OC3 install.

Hi, I followed the instructions from this link to upgrade my NC1 phone to OC3, and it worked fine, until I flashed another ROM: http://forum.xda-developers.com/gala...4#post61352064.

I flashed this ROM: http://forum.xda-developers.com/gala...l-1-0-t3049564, and was stuck in the startup sequence for like 10 minutes, so I went back to odin to see if I could flash back to NB1, and I get failed, saying:

And when I try to turn on my phone from then, it says that it failed a Kies update. I've tried different USB ports and different cables, but I get the same result. How do I fix this? I cannot afford to get a new phone.
