LG seems to have pulled the V7 update from their site, meaning that we need the .cab file to do the update to the Fathom now. The only place that I knew where to find it seems to be dead now, and I've only got hte V5 one.
I'll keep looking, but does anyone have a copy of it?
Official file name:
VS750ZV7_04.SV7_04.P58006.R5.cab
Let me know if you find it, and please upload it somewhere so I can save it.
