20 Most Recent RCA M4204 MP3 Player Questions & Answers


Sounds like you've exceeded your device's storage limits.

If you can hook it up to a computer, go into the device's storage (via a file explorer), delete 5 or 6 MP3 files from the player. They usually average 4 to 5 MB's each. That should give the unit enough free space to start up correctly.

Restoring RCA M4304A Recorder Firmware

Symtom: recorder shows OPAL splash screen, then shows "profiling requires20mb of free space, shutting down" and then shuts down. Recorder cannot be accessed by windows or the RCA easyrip software.

Solution: Use the firmware update found here: http://www.voxxsupport.com/images/downloads/OPAL_066F_85A4_85A5_0_1140_SIG.EXE

This update needs to be ran on an xp computer running 32 bitOS. It was tested in a Win 7 64bitmachine and proven to not work.


Necessary steps taken to get the firmware to properlyrestore were as follows:

1. Hold in the power (menu) button for 10 seconds(the splash screen will show and it will give the error message, ignore it)

2. While still holding the power button, press theplay/pause button and hold down.

3. Release the power button while still holdingdown the play/pause button and wait 5 seconds.

4. While still holding the play/pause button plugin the usb cable to the recorder. Continue to hold the play/pause button foranother 5 seconds after plugging the cable in.

5. Release the play pause button then launch theEXE for the firmware update. Minimize the instruction screen so you can see thefull update screen.

6. Leave the format checkbox checked (check it ifit isn't checked) formatting is crucial to this working.

7. Once the status in the update window changesfrom initializing to ready click start to update the recorder. It will go through formatting, then updating.

8. Once the status shows complete disconnect therecorder and with any luck the recorder is usable again. The media files will obviously have to bereloaded, but the recording is functional at least.

MP3 players expect an MS-DOS (or FAT) format.

They do not read Mac formatted memory.

Reformat the MP3 player to MS-DOS format (your files will be deleted, so back them up if necessary) and the player should read the memory once more.

  • Battery may be depleted. Please recharge.
  • Ensure the keys lock is not activated.
  • Reset the player by pressing and holding Power/Menu for more than 10 seconds.
  • If the player still cannot be turned on after resetting, perform a firmware upgrade to restore it.

Upgrading the firmware solved the problem, but it took some effort.
The firmware update is found on RCA's website here: http://www.rcaaudiovideo.com/product.aspx?product=392.
You must first hook up the player. Download the updater to a file folder on your computer. Run the software....and I had to use one of the troubleshooting tips that is available in the firmware upgrade to even get my machine to recognize the mp3 player. That trick was to unhook the player. Push and hold down the play button as you reconnect the player into the computer...and remain holding the play button down until the player is recognized. All of these steps are in the firmware upgrade program. It's crazy to me that you have to start the program to upgrade the firmware before they give you any idea on how to make it work (especially if your mp3 player seem dead).
Anyway. I lost all my saved media, but the player is working again. Good Luck.

There's a small switch on the back of the unit. Slide it to the left (away from the microphone).
