I tried to update my tv KD-55XE7096 but I found out that my firmware is old (v8.764-1000-1.700-00) and cant be updated online (v8.885) or by usb. When I tried the usb update with this one but I got an error that there is no relevant files in usb "No suitable update data was found". 

I also found that to update to v8.885 you need v8.535

I did search in support site and I could find only the one before (v8.535).

I tried to update via usb to v8.535 but I again received the error "No suitable update data was found".

Where can I find firmware files older that v8.535???

Or am I doing something wrong with the usb update to get this error ?

I did formated usb to fat 32 and followed the instructions for usd update.

Any help is appreciated.
