thanks, hope it works... i have a mini CD, but there is just Windows Media Player 9 and the MP3 Player Utilities on it

thats my unrepairable Firmware dump
would be nice if someone would have a firmware for my MP4 Player or that it will be possible to do it like the other firmwares (repairing and recovery etc.)
