Update: The seller wrote me I had the newest firmware in it 9.1.52 and that the one which came with cdrom was old 9.0.52. He told me to find
firmware:
LSD_91N18V_A1,2007-08-04,9.1.52 which I downloaded from internet.
Using the DEAD player revival guide found at
http://www.mympxplayer.org/viewtopic.php?t=567?48dc7e60 I get my device reinitialized as adfu device but, now I can not format it anyhow anymore. And as it can not be reformatted I can not put the necessary firmware back. Does anyone know how to
reformat if it does not allow to do it?
