Kosh , you'll need to try all the v3.5.35 firmwares for your screen size here
http://www.mympxplayer.org/actions-3535-dc15.html
If all of them do not work, try the v3.5.37 as well here
http://www.mympxplayer.org/actions-3537-dc16.html
Once MP3 Utilities Upgrade Tool do not recognise the player, you'll need to perform the Dead Player Recovery Guide here
http://www.mympxplayer.org/dead-play...ide-vt567.html
When you get it recognised again, continue with the firmware testing.
Good luck.
