Phone model number changed after flashing rom

Hi ,

I have a flashed a rom that I think did not work for my model ( Now my phone says model number is SM-G925K) and I have no more signal. I believe the model number is the issue, but I'm not sure...

It was supposed to be a SM-G920W8.

Any idea how I can reverse it back?

This is the rom that I tried to install : http://forum.xda-developers.com/gala...11-0b-t3295183
