    I've had the exact same problem with my Opal RCA M4008. It is not detected by my computer when plugged into the USB port. It's just dead weight. Also, RCA's customer service website is a complete joke.

    I'm having the same problem with my m4008a. My computer just doesn't recognize the player. I've tried using WMP 10.0 and the Yahoo Music Jukebox that came with it but I can't find it anywhere. I even tried the reset button. Nothing. It did recharge the battery, though.

    Well When charge it Stays On OPAL and then its says BootError

  • twdennis97 Apr 24, 2009

    The disk for my mp3 was installed in 2007 on christmas. By May 2008 I already had the things neededto download music on yahoo unlimited. My mom and I tried to do copy and paste where the instructions said to, but it didn't work, so i recorded songs. On March 30, 2009, I tried to charge it. The screen just showed OPAL, so i unhooked it, put a staple in the reset button (that works if it won't turn on after being charged), and it had a blank screen. So I hooked it back in and put a staple in the reset button at the same time and it still showed OPAL when I unhooked it 4 hours later.

This is the BEST solution. I just had the same problem and ran across this solution and it actually worked. If you are experiencing this problem, this is the only fix I found and I have tried several. Solution #2 posted on Dec 30, 2007 RCA Opal M4008 - 4%20stars_w.png

I had this problem. Backing up data wasn't a concern though, as I hadn't anything on the OPAL yet.
First I let the OPAL charge up for 3 hours. Then I made sure it was powered off. I had previously downloaded onto a PC the firmware update for the M4004 which also works on the M4008 and other OPAL's. I plugged the OPAL into the PC, and booted up the PC. After installing the firmware package in the PC, you get an install screen for the new firmware with a format option for the OPAL. I selected that option, but the "start" button was greyed out as the PC still couldn;t see the OPAL. I pressed the reset (paperclip in the back of the OPAL) for about 15 seconds, than held down the "Play" button and waited. Eventually the software recognized the OPAL, and started to format it.
If you get a dialogue to restart the PC, press NO! You have to read the instructions that come with the install. Eventually I reformatted the drive, and installed new firmware.
BTW, there was no picture folder after I did this, so I just created a new folder named picture and it worked fine for the thumbnail pics I threw in there. Also when I use a MAC with the OPAL, I power the MAC up with the OPAL off but attached. After drag and dropping files into the OPAL, I power down the MAC. After power down the OPAL will after a pause give the "building databases please wait" messages, then when done go to the start menu. It is difficult on a MAC to eject the OPAL, it just reappears on the desktop so shutting down is the only safe way to administer the device. But to update firmware, which is easily corrupted BTW if you unplug the thing at the wrong time, you HAVE to do it on a PC operating system. Might work on an Intel MAC with a PC OS though.
Hope this helps.

Try it in another computer, in my windows xp it read the program, but not in the Vista. Format it over there and download the Firmware there too, it works.
Good luck

If the player is turning on an off while connected to the computer, its not because of the opal. This a data sinc error caused by media player. The program goes into a loop trying to get the data to build and trying to get the player to start. Solution: Back up your computer - uninstall media player. The computer should now recognise the device as an MTC instead of MTP. (or you can go into system properties an change opal to MTC manually but who knows how to do that)

---MTC means that the computer will treat the player just a flash drive---

Personally, I find that treating the opal like a flash works way better and Media player 10-11 s^&^ks. If you want a good player you should download media player clasic because its not invasive about things and dosn't force auto-updates.

The problem you have with your opal could be the problem I had....

Now about the problem "I" had with the player. For some weird reason the player just stopped recognizing picture files with the Srgb color profiles and would not build a data base if I had pictures with Srgb profiles.
Solution: I had to save the pictures a Adobe RGB 1998. (I also found that you can save the photos in Paint and it works just like photoshop)

There might be an issue with the firmware that is currently on the device. Sometimes these files get corrupted.

Download the firmware update from here:

Follow the instructions to install the firmware on your device. Be sure to back up any important media on your player in case the firmware reflash wipes it out.

RCA OPAL M4008 screen is blank and now it won't come on

Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

Try using this it worked for my m4002a. It's the firmware update software.

After downloading that just follow the instructions that pop-up with the program.

Mine wouldn't do anything before i tried this and afterwards it's been working without a problem.
