Need help with editing a kdz file for LGUP - LG V10 Q&A, Help & Troubleshooting

I have posted about my problem in several threads now, but I didn't get an answer yet, so I hope I can finally save my phone with your help here... It's been a major pain the cojones for two weeks already.
In short, here is what happened:
I unlocked the bootloader, installed TWRP and after flashing superSU (once I found out how to get into TWRP), I got a bootloop.
So I wanted to do a full wipe. But I messed up and wiped literally everything, even the OS
Then I went on to look for a stock ROM zip file. I found one, but I didn't read the whole article which said it was for H901. I installed it and found out it's branded T-mobile version on top of all.
Now I'm trying to get back to a H960A stock ROM, but no luck so far.
I have tried both methods from the LG V10 Stock Firmware (Go Back to Stock) KDZ & TOT Method thread
Then there was a shed of hope when I stumbled upon this thread, where the OP managed to do the same
http://forum.xda-developers.com/lg-v10/help/flashed-h901-h960-comrade-to-help-t3429025
I downloaded the modified Switzerland file mentioned in one of the comments, but it didn't do through for me.
I also tried to run the chkdzdev tool to change my EU version KDZ file, but agian, I got the same error (possibly I didn't do it right, since there is no manual whatsoever and the author doesn't reply)
Here is a screenshot of how it went:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So now, my only hope is to:
a) find a zip with H960A stock ROM (probably none exists on the interwebz)
b) find a TWRP backup that I can "revert" to (not sure if this would work, but if anyone would be so kind, I could find out...)
c) find someone who can modify the KDZ file and tell me how to do it
Anyone?

Try this. There is some instructions here that might be different from what you've been trying.

It's saying after you load the firmware into LGUp, you have to close it and then open it again, select refurbish, and then make sure bin file is checked. Hopefully this can get you going. Good luck.

I've tried this one... it wouldn't even let me load the kdz file without doing this...
Problem is, the firmware version is coded somewhere deep in the file and it won't let me install it on a device that has a different version (unfortunately mine was overwritten by the stupid stock ROM i've managed to install)
