Dead player - No ADFU
 

Hello, about a week ago, I bought an mp3 player on the web. And now, somehow, the mp3 player is dead.

Processor chip: ATJ2091H
Memory chop: K9L8G08UO0M (The guy I bought it from said it'd be a 4GB player, but the memory chip seems to be 1GB :/)

It all started off with that I couldnt format the player with the Disk tool that followed, so I thought, as the disk was FAT32, I formatted the MP3 with windows regular FAT32 fs. (I can also add that my PC was still able to find the mp3 player after the format)

Anyhow, I started uploading mp3s, and it all went fine. I turned the mp3 on and tried to browse to "Music" mode, whereupon the hourglass shows, and the mp3 restarts itself. Now when I try to connect it to the PC, no drive shows up.

What might have happened? Have anyone else had the same problem? May it have gone dead because I uploaded 3gb to a 1gb memory chip? (even possible?)

All help is appreciated, thank you!

snatchit,
At present there appears to be no evidence that 4GB players exist they all appear to be smaller chips hacked to read larger than their true size. At the moment 2GB is the max memory supported. As you have found once you start loading files to the player over the chips true size things start going wrong. File corruption, player restarts and resets and total crash of the operating system.

Most of these players use the ATJ2085 chipset which can be recovered by following the Dead Player Recovery Guide provided you either have a backup of your firmware or can find a compatible firmware.

The problem you face is that your player uses a newer ATJ2091 chip which uses the version 9.0.48 firmware. Sadly at the moment there is no way to extract the firmware from a 9.0.48 player as the backup tools can not read it properly. The result of this is that there is no recovery firmware available at present. Anyone with a dead 9.0.48 series player is stuck with a dead player until a tool becomes available to extract this firmware, then we will see people start uploading their firmware.

I suggest you try to get a refund from your seller.
