I need a dump of Lisong Wilson (Samsung 725 ACU7503)firmware
 

Hi
I need a dump of Lisong Wilson (Samsung 725 ACU7503) firmware v 9.1.50. Please someone help me.
I purchased that MP4 player on e-Bay. It comes with 8GB compressed drive. Yesterday I received "Disc Error" and I have to format it. Now the disk is 1GB. I knew that, but that wasn't the main problem. The whole navigation has changed and become aggravate. I tried to upgrade and repair the firmware, but by mistake I have downloaded something different. I loaded Glacier_9.1.51.bin latter, but that turned my player into "S1 Wilson" MP3 player (as same as the other one that I have). Windows recognized that player very hard. The screen stays black etc.
The old firmware was 9.1.50. It won’t let me go with Glacier_9.1.50_1.bin; it says "invalid firmware". I'm using MP3 Player Utilities 4.05.
Please help
