Here are instructions for a solution to your frozen Coby 610 problem. This works even though the MP3 player is having problems talking to your computer. They should communicate fine after this update.

Replacing the firmware of your Coby 610 MP3 Player will unfreeze it and help it act normally again. This will also fix the 'File System Error' that has been popping up with some Coby 610 players. You can find it at the website by choosing 'Mp3 & Portable', then 'Mp3 & Mp4 Players', then your model 'MP610', from the support page. Or, here is the direct link to the file from Coby's servers.


Unpacking the zipfile from the Coby Website will give you a PDF file with instructions, and a program file to run.

Your music will be erased when you run this firmware update. The instructions suggest that even if your mp3 player won't startup properly, if you plug it into your computer you should be able to access it as a removable disk, and copy all your music to a temporary folder on your computer.

Here are the steps:

  1. Plug your MP610 into your computer.
  2. Copy all your music to a temporary folder.
  3. Disconnect your MP610 from your computer.
  4. Disconnect as many USB devices as possible from your computer (to simplify identifying the MP610 at a later step, and avoid damaging other devices by trying to load the MP610 firmware into them by mistake.)
  5. Run the Firmware Update program 'MP610 T LCD Firmware Update for file sys err.exe'
  6. You will see a screen with up to 24 numbered, empty boxes.
  7. Connect the MP610 to your computer. It will show up in one of the boxes.
  8. Once the MP3 player shows up, click on the Firmware Feature icon to start the firmware upgrade.
  9. After the firmware update is complete, you will receive a checkmark in the firmware box.
  10. Disconnect the MP610.
  11. Close the firmware update software.
  12. Turn on the 610 to confirm it starts up and the display reads 'COBY'.
  13. Plug it back into your computer and copy your music back on to it.

I hope that helps.

Unable to select random option, or any other option!

It does not say so in the manual, but you must hold down the Enter key (the center round button) and while doing that, press the Option button (the equals on the right).

I have a coby mp828 and I am trying to shuffle songs. I have the random function highlighted and it still won't shuffle..Any ideas

Start playing a track. Click anywhere on screen. Options should show at top of screen. Click on the tool symbol (should look like a bolt.) Click on repeat mode. Click random. This should solve your problem.

Why does sony E436F MP3 player change the order of the songs

Your music has likely been put on shuffle. Look on the screen while songs are playing. You will see two crossed arrows or the word shuffle or random. Check playback options and see if random or shuffle option has been turned on. Sometimes the program you use to put songs on the MP3 player will activate this option if the program's playlist is on shuffle.
