GoldenZero , although i've seen these sunglass players appearing on ebay recently, but i'm not sure what chipset or firmware version they running off. They might not even be Actions chipsets, which would mean most tools on this site could not be used on yours.
Another alternative would be to format using HP Format Tool here

If it still does not work, you'll need to open the sunglasses, not sure where to open, but the processor chip should be located somewhere within it. Then you'll need to perform the Dead Player Recovery here

Good Luck.
