Exclamation [Q] LG LS980 big problem - bricked? D801 firmware

Hi,
I have a big problem with LG G2 from Sprint (LS 980). I've bought on eBay for using in Europe. When I bought it, one of very few optionw to use it for GSM carriers was flashing Justin's ROM - it is stock T-Mobile ROM modified for Spint G2. Everything worked well except NFC.

After some time new (and permament) method for unlocking Sprint G2 arrived, so I wanted to do it that way. I've made factory reset on my LS980 (with D801 T-Mobile ROM from Justin), but I didn't know, that I had to go to recovery (Vol - plus Power) for wull wipe and didn't do that. My phone is now in bootloop (T-Mobile animation goes still around ) and phone doesn't boot up. I don't know how to get it back to stock.

What works:
Download Mode (Vol + and Power), Unknown Mode (All three keys together) - there are options ON, OFF and Cancel (Answer Call and something with alarm)

What doesn't works:
Fastboot, recovery, boot

I've tried to get into recovery many times, but with no luck. I've also followed many instructions how to get it back to stock. As the main manual I took this topic:

Sure that with Sprint LS980 flash files.

It is basically same as this:

Everything went pretty well until flashing part. LG Flash Tools don't want to flash my phone because of model number mismatch ...I have LS980, but it thinks that I have D801 (T-Mobile version).

It there anyway from this mess?

Thanks for every suggestion.
