At this point it would be worth the effort to format it again and don't use the quick format option.
As mentioned a bunch of times in this thread, the only reasons the phone won't see a PB31IMG.zip file on the root of the SD card is either the file is named wrong or the card isn't formatted to fat32 properly(could also try a different SD card).
I will try re formatting, thanks...
As for trying a different SD card? Mine isn't removable.
