shyam , i'll suggest that you try all the v3.5.37 firmwares here
http://www.mympxplayer.org/actions-3537-dc16.html
If none of those work, try the v3.5.35 as well here
http://www.mympxplayer.org/actions-3535-dc15.html
There are a few pages of downloads to try, and would take you some time. But as there is no way of telling which firmware would work with your player, you'll need to try all of them until you get a working one.
Good luck.
