Fixxxer,
Sorry I thought you had used the Dead Player Recovery Guide.
Basically when a player dies and is not detected by windows and the upgrade tool the player must be opened and the memory chip has to be shorted by crossing some of the pins. This resets the memory chip.
Look at the Guide

The information on a write protected ADFU Device was that the battery needs to be disconnected so that there is no power going to the chip. The pins of the memory chip then need to be crossed while the player is being connected to USB.
