hi, mine just bought mp4 player a 2gb ipod nano alike model, yesterday,

same with you the firmware version is 9.0.48

so it mean that i currently cant edit the firmware nor changing its theme?

The current theme from the manufacture is suck, i don't like it at all

skoolboy, If your player came with a copy of the firmware on the Mini CD then you may be able to edit that but you can not extract the firmware from your player to edit it.

I have a nano clone 2gb. firmware is 9.0.50

I cant seem to backup my firmware and also no way to upgrade it. If i can somehow get a copy extracted, cant i just edit that and use upgrade tool?

But the issue is that even the upgrade function doesnt seem to work.

junooni, There are no tools yet to backup\extract 9.0.48 or 9.0.50 firmware.

YOU CAN EDIT THE THEME ON 9.0.48. Just read my thread, it explains how.
