LG FlashTool Error, can not boot D850

Hi, Guys

I went the following operation.

1) I was trying to root on D850.
It was success.
2) I was trying to install TWRP3.0 from TWRP manager.
But it failed. Then I could not install the TWRP2.8.
3) I have tried a factory reset from LGFlashTool.exe
I can not be factory reset.
Error occurs.
