In case you have a problem to connect your Samsung YP-U2J Mp3 player, you should update Firmware to get it working. The new Firmware may be downloaded from Samsung.com or for your convenience you can download it from here. I got this error after I installed the Windows Media Player 11 several months ago but I could not figure out why my Mp3 Player was not working after a couple of Google searching.
Here is the instruction:
- Download the YP-U2J Updater
- Remove Mp3 player if you already connected to the USB port
- Run the program (You should see something like: Please connect the device)
- Hold down the Play button and connect the Mp3 Player to USB port (Hold down the play button while you connect the device, you should see a message (normally after 8 seconds) like: Initializing on YP-U2J Updater program screen)
- After you hear the Windows chime "new device found" or the message "Initializing" on YP-U2J Updater, you can now remove your hand from play button.
- Check the Format Data Area checkbox (By clicking the yes button, you will lose all of your data in your Mp3 player)
- Click the "yes" button
- Finally, click on the Start button (takes less than a minute). DO NOT REMOVE YOUR DEVICE
- IMPORTANT: After updating the firmware, you MUST disconnect the Mp3 player and turn it on. You will see a 20% message for about 50 seconds and it will be restarted automatically.
Update: Please keep in mind that if you sync your Mp3 player with a computer that has a Windows Media Player 9 or 10, you should do these steps again.
