1. Go out and sell it on ebay. Say only one problem with it. And under description say special software needed to use correctly. make sure it is at a low price and yoou put correctly, cuz half th people on ebay dont use the things correctly. 
   

SOURCE: My coby mp 610 wont play all the music i have on it.

I use a different MP3 player, but I noticed that mine wouldn't play .AAC files, only .MP3 files. I upgraded the firmware of mine and then it played everything. I noticed there is a new firmware upgrade for the COBY 610, so that might be of help to you.

You can find it at the cobyusa.com 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.
