Hi! I need help - I have LG D855 32GB (International). I dont have DOWNLOAD MODE. When I try to boot to download mode I get LG logo and "Firmware upgrade" screen. (Same when I boot the phone or factory reset). I cannot flash KDZ - flash fails, I cannot flash tot(Model information check fail). Support tool and LG pc suite fail as well.
LGPNST shows "UNKNOWN in model" , and I don't have a dll for it...
In device manager I see :
1)LGE AndroidNet USB Serial Port (41) - under "Ports" * I configured it..
2) LGE AndroidNet USB Modem under modems
Is "Firmware upgrade" in fastboot mode? (I can't communicate via fastboot)
Should I reinstall drivers/which/etc?
How go I get to fastboot?!!!The tutorial looks great but I'm stuck in getting to fastboot
Any help will be appreciated.
