Denon 2910 and/or 955 Firmware

Here you can find the Firmware for Denon 2910 (also known as 955 in USA) International Version.

I personally tested every firmware you can find in this site, but you must understand that to update the DVD Player is YOUR CHOICE and I DO NOT GUARANTEE IT WORKS FOR YOU !!!

I tested English, French and German players and I had no troubles at all.

It can now read ALL DVD Codes BUT if you only need to make your player codefree without updating the firmware YOU CAN USE THE REMOTE TRICK (above).

USA (Region 1) players are reported to work with this firmware, but I could not test.
