All the actions described below you do at your own peril and risk.

Recovery firmware in Flash MP3 players.

Flash mp3 players fail even during normal operations, and even more so there is a great chance to mess up the device with the firmware. Here is a way to restore player software at home. Recovery will take you on the strength of half an hour.

As an example, take the player RoverMedia DP300Fm built on the basis of the SigmaTel 3500 chip. The player was successfully killed during the firmware process.



If the player is recognized by the computer.
1. If the player is recognized by a computer, then connect the player with the play button held down and reflash with the firmware that came with the player on the disk, or download from the manufacturer’s website.

If the player is not recognized by the computer.
1. Disassemble the player. We need to get to the memory chips. If the body of the player is assembled on snaps, I advise you to take a plastic bank card or any other.

2. We look at the marking of the memory chip, they look like on the image. These are mainly chips manufactured by Samsung, Nec, Hynix. In this case, the memory of Samsung 543 K9K4G08UOM.



3. We are looking for information on the chip (DataSheet)http://www.datasheetcatalog.com

4. Using the document downloaded fromhttp://www.datasheetcatalog.comWe find the legs on the chip labeled IO1, IO2, IO3, etc.

5. Now you need to close two any IO legs and connect the player to the computer, it may not work the first time. This can be done, as I did, with a needle.



6. If you successfully closed the legs, the computer should notify you that a new MP3 Recovery Device has been found, the driver to which you can find on the disk that came with the player. If there was no disk in the kit, try those that are in the attachment.

7. Flash the player according to the instructions.
