Bought two MP4 players (iPod Nano clones) one is dead

[jerrit]

I bought two MP4 players (iPod Nano clones) off of ebay, one works fine and one just gets a blue screen (It did work fine for a day).
I tried a firmware dump off this site but it made it so it no longer was seen by Windows Explorer.
I did the memory chip reset and now it's detected as an ADFU Device.
How can i get the Full firmware off the good working device?

I have tried s1fwx and it gives me a dump.bin (6mb) but I get an error when trying to upload it to the bad MP4 player

here is the type of player I have:

Also note that on the good player in the player setup it says the firmware is 9.0.50.00 but MP3 Player utilities says the firmware is firmware 9.1.50, not sure which one is correct.

The S1fwx won't work for that version at this time. It is good to version 9.0.43. So don't do anything at the moment until a reliable firmware dump can be retrieved from your new one.

I did find a 9.0.50 full firmware off this site and it did recover it back to a 1GB flash/pen drive and gave it a drive letter but I still get just a blue screen.

That may be because it is not the right firmware for that type of player. Becareful of firmware until you find the one specific for that player. Many players will have the same number version.

The firmware may be looking for a full screen (1.5 or 1.8 ) to write its data.

Well it seems to be working fine as far as playing music, it just has no display...my daughter seems ok with that and she will just use it until i can find a firmware that fixes the display.

Thanks for your help.
