please see the following thread and confirm if your player is similar to the one discussed
http://www.mympxplayer.org/image-vp51898.html
if it is, an i know yours has a camera but he same applies
there is no way to extract your firmware
there are other firmwares BUT no guarantee they will work on yours player
so basically if you do not have the right firmware then no modding can be done and there is a strong possibility you may break your player by trying other firmwares from similar players
