Thothie,
9.0.xx series firmware is quite new and because there is no way to make a usable backup there is no point uploading extracted firmware. So you will have a hard time finding any on the net. Some players come with a copy of the full firmware on the mini cd but it is rare.
From looking at your firmware you player is a 1.5 inch LCD so download Mp3 Player Utilities 3.68 from here

There is no way to enable the telbook feature if it is disabled. The cd's are generic so the apps are there if your player needs them or not.
The dodgy screen is a worry, all up I would be looking for a full refund if the seller wont help. He should be able to get you a full version of the firmware from his supplier.
