Please help dvd recored/combo bad firware upgrade

i upgraded samsung dvd recored/combo with bad firware upgrade
i need austrailian file and cant find it at samsung . or samsung . com

where would be a good place to look for it

i dont think there is austrailian update but original would be great

below is url of the files i flashed after being redirected from austrailian site

Were there instructions with the firmware,
or somewhere on Samsung’s website?
If so, did you follow them to the letter?
Is the machine still under warranty?

I see at the website there are two versions
of your machine, the DVD-VR320 and the DVD-VR320P.
You never said what model your Samsung is…
