Hi arish_06,
I've seen a few times where it would error out with a "not a valid firmware file" message half way through. That was because I made changes to my firmware but forgot to 'repair' it using the s1fwx. So, it seems strange yours won't upgrade even after you've repaired it too.
I'm thinking maybe the firmware is not right for your player?
If I had the firmware for your player, i would upload it, but I don't.
