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

I have experience rom'ng Samsung phones and have never run into something this bad. My S6 Edge SM-G925P will not flash any stock/non-stock rom. Tried OI1/OH/OJ/OF, all fail Nand Write. Some suggest, split ROM in pieces and install separately in ODIN, but do not explain what that means and how to do it. When USB (official samsung cable) plugged in, phone gives Smart Switch error. I am attaching screenshots as these say it all. Please, any 'good' advice on how to attempt fixing this and getting ANY Android OS version installed? Am at wits end with this. Also, I can't get the SN because the dog ate the box and it's not on the back of the phone, plus phone won't boot other than download mode.
