Re: rca opal m4002a

Trouble - this player is not MAC compatible - you will always get that error

everyone else -
The Opal has a reset hole on the back of the unit in which a toothpick (non metallic) can be inserted to reboot the player.
If this does not work, I suggest that you reformat the player by using the WindowsTM format command on the unit. To reformat the memory

  1. Right click on the device within the Explorer or My Computer window
  2. Select the format command (full format) to reformat the internal memory of the device.
  3. Reinstall the firmware from

What song service supports rca opal m4002a mp3 player. napster doesn't work?

Not iTunes. Not Napster.
You could try Rhapsody's MP3 ONLY service - new!
Limewire works, but make sure you anti-virus program is up-to-date.

The key is to use Mp3 format only, and most music services have switched to WMA format.

Hung in a transfer loop after being removed from PC

When I (USB) plug in my RCA Opal M4002A mp3 player into my "Office PC" it works fine, but when I plug it into my "Studio PC" the "Opal" screen shows "USB connected" and so does the "PC" with the "Device Connected Sound" but then the "Mouse Pointer" changes to the "Hour Glass" you hear the "System Notification Sound" then the "Mouse Pointer" changes back to the default "Arrow Pointer" and this back and forth action loops endlessly until I unplug it. I've tried everything. Any ideas would be greatly appreciated. Thank You, Quaal
ALSO I HAVE THE "RCA Opal M4002A" (2GB) mp3 player.
*** After much trial and error this FIXED my problem. ***
1 - First right mouse click on "My Computer".
2 - Left click on "Properties"- Left click on "Hardware"- Left click on "Device Manager".
3 - Now with one end of the USB cable plugged into your mp3 player, plug the other into your USB port. (Now when I did this a new "Portable Device" icon with an "MTP" Driver (sub icon) showed up in the "Devices List". (The "MTP" icon had an "!" on it, telling my it wasn't working properly. I then did this.
4 - Right click on "MTP" driver icon, then ...
5 - Left click on "Update Driver". (I was then given two choices. The top one was the faulty "Portable Device" driver which I had done everything I could to fix, but nothing worked. So I then did this ...
6 - Left click on the "Mass Storage" Driver (the second choice below it in the list), I then clicked "OK". The "Updating Driver" screen showed for a moment. The "Portable Device / MTP Driver(!)" icon vanished from the "Device Manager" devices list, But the looping STOPPED!!! My Opal was working beautifully and showing in my "Root Directory" as Drive j: and in "Device Manager" under "Disk Drives" as "Thomson Opal USB Device".
P.S. For some reason the file transfers are noticeably faster now. Good Luck, Quaal

Have you tried resetting it? Theres a small opening on the back. Use a blunt object to press the reset button and then plug it in to your P.C. that will reboot it.

Opal mp3 1g

Sorry I don't know where the "Profiling requires 4mg of free space" came from. But one thing I do know is that one GB of space should hold up to approx 600-650 songs unless they are WAV files then they take up 30 megabytes per song.

Hope this helps

RCA Opal M4002A Need screen

I have an Opal 2GB mp3 player just like yours and I accidentaly busted the screen on it, so I e-mailed the RCA company, they e-mailed me back telling me that I voided the warranty, and I would have to send it back and pay 55 dollars to get a new one, because they don't sell the individual screens.

I hope this helps.

Mine didn't recognize either, so what I did is go into the device manager, find the opal in the listings, double-click, disabled the device, re-enabled it, at which time it shows that there's a firmware error. I then re-installed the driver from the cd, unplugged the opal, plugged it back in, and for whatever reason, the computer then recognized the opal as a mass storage device, instead of a portable music player. The computer now sees it everytime, and all I have to do is drag and drop any files I want into the opal. Works like a charm. Hopefully RCA will provide an updated firmware program in the near future, but this might work for you for now. Good luck!

Hi, you can try to upgrade the player's firmware, you can download it from the RCA Website (moz-screenshot.jpgmoz-screenshot-1.jpg, the firmware it's the second app listed.
If your computer doesn't recognize the player, you'll have to turn it off and keep "PLAY" pressed for 10 seconds while connecting it to the USB port, then update the firmware.
