D855 can't flash after boot repair
 

I have repaired a D855 with Medusa, it was asking for Qualcomm driver. Now phone gets LG Android Modem driver and LG Android Serial Port when I connect usb cable pressing vol up button. Problem is nothing comes on the downloading screen and phone can not be detected with any software. I tried Octopus LG, LGFlashTool. I have also changed driver.

What could be the problem?

Hello.

We will check where can be the problem and will try to prepare test Software for You.
