Dead mp4 player, DM737
 

Hi there, i have a problem, my device (4 years old device) is dead, 'cause a faulty firmware upgrade i assume, it doesn't turn on, even when i conect it to the computer, i have the original firmware (on the drivers disc), but i have no way to put it in, my device uses a 1 inch ST1 hard drive, 4 gbs, any suggestions of how to get it back to life?

Thanks in advance.
