Well, as you might see from my signature, I am running 6.0.507 - from a clean install of 6.0.500 - on an F2-424. I downloaded the .ins file from the support pages, but from another model. However, I don't expect help from the support people if it all goes haywire. The .507 update was installed via the system update page, so I have no idea why it doesn't work for you. Maybe it is suggesting that you start again from .500 since it mentions "the installation package".
I started at 6.0.229 from what I remember 6.0.420 through a number of updates to 6.0.500 and then 6.0.507.
