Hey guys,
I have an LG G3 - D855 phone .. on Stock Marshmallow 6.0 .. and it IS working fine ..
The thing is i want to return to Lollipop, so i decided to use LG Flash Tool to reset the phone to its original state
I Press volume up while the phone is off, then connect it to USB .. it goes into download mode ... but in Device Manager it shows ONLY ONE port " LGE Androidnet usb serial port " .. and of course i'm unable to use LG Flash Tool
I exit download mode .. turn on the phone ... connect USB .. ONLY THEN that i can see "LGE Mobile USB Serial Port" .. i mean it shows ONLY When the phone is ON
I've tried so many Drivers ... even the latest one .. on LG site " LGMobileDriver_WHQL_Ver_4.1.1 " .. Yet no result ..
Is there anyway to fix that ?!
Have a nice day!

Have you tried changing the com port to 41 while in download mode.
You rom file it is .tot or .kdz ??
