please, please help me, double problem
 

hello, I received my mp4 player ( style ipod ), and I wanted to upgrade the firmware. It didn't work, I only had a blue screen. I dried a lot of firmware, and, the 6 one, made my mp4 player undectable. My computeur doesn't detect my mp3 ( not as a mp4, not as an hard disk ). I tried with another computer, it's the same problem!

I don't know what to do, I can't have lost my money like that.

thanks

mimik,
If that is the case then the only option you have is to try the Dead Player Recovery Guide HERE. If you have backed up your original firmware you have a pretty good chance of recovering your player, if not your chances are not so good as you will have to try random firmware till you find one to suit your player.

I tried, my computer does'nt detect it anymore ... I ll try again,

mimik, Are you shorting the memory chip as outlined in the Dead Player recovery Guide?
