Default [Q] How do you fix/solutions QHSUSB_BULK similar to the LG G2?

Sorry to be an annoyance to make another post about my hard bricked LG D851. I was wondering if there is the solution similar to the LG G2 that can unbrick my phone. Attempted:LGflashtools, download mode, powering on the device, etc. ALL FAILED. So if there is any solutions or links to download, I will be very thankful for your kindness
