last-hero , do you still remember your previous working firmware version number?

Does the MP3 Utilities Upgrade Tool detect your player?

last-hero , in this case, you'll need to perform the Dead Player Recovery here http://www.mympxplayer.org/dead-play...ide-vt567.html

Once your player has been installed back to ADFU state, you will need to try all the v3.5.37 firmware dumps for your screen size in the downloads section here http://www.mympxplayer.org/actions-3537-dc16.html

If none of the v3.5.37 firmwares work, then you'll need to try the v3.5.35 too. There's no way of telling which firmware will work with your player, so you need to try all of them.
