Help! Dead player + Unrecognized by Windows

[samirjin]

Hi everyone;

I had a small problem with my mp4 player. I upgraded it but using another version: 9.1.52. The result: dead player. I upgraded it again using the version 9.1.51. The new result: dead player+unrecognized by windows.

Here are my MP4 player's features:

Firmware: 2006/03/13 - 9.1.51 - ACU7515_s75 - 2006/12/07
Title: MATRIX FPC-TGS000190AC02-00 Ver0.1 - SAMSUNG 716 K9G8G08U0M PCB0
Plate No: BO-050
Screen Size: 2"
Memory Size: 1GB


Others:

Mini SD slot
Speaker
FM Radio
Sound Recorder

How can I make it recognized again by my PC?

And please I need the firmware.

Thanks in advance.
