when i upgrade my LG G3 to android M,it went dead.No boot/ led/download mode.Only shows Qualcomm HS-UDB QDLoader 9008 port 7, when connected to laptop.Itried to recover it using SmartBootDiagv1.3.1 tool,,

main problem is my phone model.A sticker where we place battery shows it is D855 made in korea but at top and and in loud speaker piece it is written as D850 0627.Still i tried this tool.. D850 model stopped at sending hello request 10 then time out
