Same problem after 3 years. Updated the firmware, the problem disappeared.
You might try 1st simple delete all files and copy them again.
Good Luck.
I have a Samsung Yepp YP-MT6 256MB mp3 player that I got 3 years ago. The problem I have is that when I turn the mp3 player on, the system load screen, then the yepp symbol and then how much free memory I have pops up but it does not load the menu. It just restarts and loops those three screens over and over. The only way to stop the looping is to take out the battery. I have run antispywares and anti viruses on the drive but it does not detect anything. I hope someone can help.
