That’s a very old firmware. It is dated 18 Oct 2010. Wth the Ver 01 firmwares you had to update to the last ‘01’ release before being able to update to the ‘02 firmware releases. That last ‘01’ firware was Ver 01.05.07’ dated 14 Jul 2011. If what was true back then is still true today, you will have to update (probably manually) to that last ‘01’ release prior to being able to update to an ‘02’ firmware version.
That last Ver 01 firmware is still available at:

Once you get that last ‘01’ manually installed, the machine might be able to update automatically to an ‘02’ version. I’m guessing that that might also be a two step process to get to the latest stable ‘02’ firmware.
