I have a Grundig MPixx 2001 MP3 player. I wanted to clean up all my data from it by formatting it. When I did, the MP3 player couldn't recognize my files that I put onto it. Then, I formatted it again with a FAT file system and some default settings that Windows said are default. From there on, the MP3 player blinks every few seconds and is stuck in a boot loop.
I've downloaded a firmware updater from here: Grundig Downloads
But the firmware updater says that the operating system isn't supported. I tried going to VirtualBox, but then VirtualBox USB driver couldn't be found on Windows Update.
Now the acts like an unformatted device on my PC. When I plug it in, it shows me a logo for file transfering and some text like usual when transfering files.
What should I do now to bring it back into a functional state?
