xsider , there are some v9.0.xx series firmwares in the downloads section here

However, the current firmware extractor can only work upto v9.0.43. So you need to wait till it supports your version if those in the downloads does not work.
If the player is still under warranty, i'll suggest you contact your seller for a replacement set.
