Hi team

I have a dead Mp3 player (blue screen) with firmware ver 3.5.37, I´m sure this is the correct firmware, due to I have another one . I can see in Windows explorer my mp3 and the files in it. I downloaded the firmware to the dead player , but I have blue screen again.
How can i detect if my problem is hardware and when the problem is software?
I have used MP3 player firmware upgrading tool ver 1.47 and 4.0

Thanks
