When I click on “upgrade start”, I get a pop up that says “Please install CSMG B2C client tool” why is this happening?
Hello Ed,
If it asks you to install the client tool, then do so using the tool.
Thanks!
how do i instal the client tool using the tool?
I do not get the three blue dots at the bottom corner of my computer. When it asks to extract all, I do so to another folder, but nothing happens. Any advice?
when I try to open the normal web upgrade test it says (lg mobile phone s/w is already running) what do I do?
How do you know if it is working (flashing) and how long does it take?
