I'm not seeing that Excel file in the Files section...just 5 files, and not that one.

The first two digits of the serial # are the country code, which mostly signifies what feature diode configurations that were shipped from the factory to determine allowable frequency coverage.? 30 & 10 are UK units.? 05 (or just 5) and 25 are US/NA units.? 25 deleted the USA TV reception feature around 02/2010.
I'm not sure what the V2 you mention refers to.? The Main board PCB artwork revision is the alpha suffix to the Main PCB part #.? Most early units (mid 2006 production had Main PCB B6249G boards.? I saw one very early unit with an "F" suffix.? In 2008 the rev "O" artwork was released and continued through 2010. I have no info on revisions after 2010 to the Main PCB artwork.? I haven't seen anything on the boards that indicate the build level of the board (component changes, jumpers, etc.)? I think that is based upon serial #, but have never seen a list detailing the changes by serial #, except for a couple of mods, like the 60M band change in the USA, and version splits identified by the serial # prefix (like 25xxxxxx for no TV reception in USA).
Much of this has been collected into a spreadsheet in this group's Files section:??Manufacture_date_vs_Serial_Numbers v1.xlsx
I know this isn't what your post was asking for, but perhaps clarifies serial # versus production dates.
