Looking for original Firmware for 2TB Mybook Elite

As the title says, I am looking to revert to the original firmware for my 2TB Mybook Elite.

The reason is because of display gauge problems mentioned in this thread:  http://community.wdc.com/t5/My-Book-for-PC/My-Book-Elite-2TB-Display-not-working-correctly/m-p/17471/highlight/false#M1064

Any help here is greatly appreciated.
