sachitmaskey , what is your player's actual firmware?
i've seen your other posts, in here
http://www.mympxplayer.org/disk-erro...e-vt2753.html?
you say it is v9.0.48
But, in another of your post here
http://www.mympxplayer.org/previous-vt3043.html?
you say that is it v3.2.16
You need to verify your original firmware. If you do not know, open your player and check for the processor's serial number (eg ATJ2085, ATJ2097, etc).
It is very difficult to follow up on your problem if you keep changing the version number.
If your player is v9.0.48, then none of the firmware related tools will work for your version.
