Hi, DEAD error means flash chip isn't working.

It may be caused by a false contact, bad weld; in this case you may try rehot flash chip with hot air using a rework smd station, using at least 400ºC with low air flow during 1 minute using circular movements. After this try repair PDS doing TP, then flash it with full flash.

If no solution after heating flash chip then you've to replace it, then repair PDS and finally flash it with full flash.
