No you can't.

A router is vastly different to an mp4 player in case you hadn't noticed

I'm saying an update can't be done and shouldn't even be attempted. You can't gain extra features in an mp4 player by a firmware 'update'.

Just because s1mp3 have certain versions, doesn't mean one of those versions will be even remotely compatible with your player. And show me where they say "You can gain extra features by updating a players firmware".. show me... PLEASE. I would really like to know.

Seriously, you can't compare a simple mp4 player to a WLAN Router from Linksys can you? You can't compare a DVD ROM or DVD Player to one either.
Just because some hardware devices can benefit from these updates... believe it or not.. doesn't mean that all devices do.
You can't even extract a full version of fw 9.0.50 using s1fwx. Oh sure you get a file as a result but if you take notice of the operations output report you'll notice errors in it. The resulting file will be missing some critical files needed to make a complete firmware dump. If it doesn't have a radio then a firmware update won't give it a radio if it hasn't got a FM Radio chip in it huh. The radio is HARDWARE.. not software.

It's simple.. if you flash foriegn firmware to your player it will die an early death. But as always, people do not believe this because they always think they know better. I could say "Go ahead and see if i'm lying, just don't come crying to me when your player dies" But that would defeat the purpose of me being here on this forum helping others.

I've said before, when it comes to mp4 players:

Is your player running Microsoft Windows? .. No? Then it doesn't need updating!

Just let me say this in advance:

"I told you so"
