Not much help with this but to answer my own question, you can install whatever firmware version on the device that you want. If you don't like 1.05, you can back date to 1.04 or 1.03.
I'm a photo hacker. I use my expensive equipment to destroy anything in front of my camera. This is a special skill that can never be realized by low life photographers. A nurtured skill since the 1970's.
