If your player did not work after doing this, I wonder if you may have damaged the input and also the firmware device from overvoltage?? |
We cannot conclude this with certainly. I believe that all USB ports are compliant with USB standards. Thus the voltage is not over 5V.
Input (USB) on the device is not damaged, because when I connect it to my PC it is detected as a USB ADFU Device. If it was damaged nothing would be detected.
I agree with you that firmware was damaged from the above procedure, but perhaps this happens due to overfilling the unit with over 1.8GB. Perhaps the firmware is stored on
the flash memory and when the data over 1.8GB was written on the device it was damaged.
Where is the firmware usually stored on these devices?
