D8555 stuck at boot animation! Flash Tool says wrong model

I have a D855 LG G3 that is bricked! :eek:
Something went wrong on an upgrade to MM, and this is where I am at:
Phone is stuck in a boot loop - plays LG boot animation, then restarts
Download mode works
Factory reset works

All 3 flash methods do not work:
LG Flash Tool 2014
Comes up with "Upgrade stopped due to an error"
LG FlashTool V1.8.1.1023(LGD855_20140526_LGFLASHv160.dll + LGD855AT-00-V10e-EUR-XX-JUL-08-2014-32G+0.tot)
"Model Information Check FAIL!" Log shows that device has no model
LGUP
"You have to select a known model, please."

Please help, I will give many thanks and a donation!
