I just got and LG G3 from AT&T (i live in Argentina) Model: D85010d with Android KitKat 4.4.2
I just tried everything but nothing works.
It's possible to upgrade to 6.0?
I tried diferents threads in the comunity but nothing explains how to do it in my version "10d"
Sometimes LG UP just say "Device: Unknown"
LG Flash Tool 2014 just say "can not connect to the server"
LG Flash Tool V1.8.1.1023 just say "Failed PreviousLoad()"
Any help with this? :crying:
