guivarrichio, if you think the firmware is similar to your original, try upgrading with it first and see if anything works at all.
I don't see how exactly you would delete the pictures from the firmware and I don't think that would fix the problem...the firmware you're talking about may have a different loading format type than your original.
The upgrade firmware must be exactly the same as your original most of the times.
By the way, have you contacted your seller?
Also, does the board ID of your player match with the firmware that you gave the link to?
