I get a screen that says:
"Incorrect firmware version
Expecting a Canon 550D with firmware version 109.
Please reinstall Canon firmware 109 even if you already have this version"
I have reinstalled 1.0.9 even though the camera was current with firmware and I am still getting the error. I am unsure of what I could be doing wrong.
Make sure you are using FIR obtained from Pelican's site: http://pel.hu/eoscard
If it doesn't work you can try to install 1.1.0, then downgrade to 1.0.9 again.
Report back, please.
So your first suggestion I could not follow through with because I am on a Mac and the file is for Windows
I was able to upgrade to 1.1.0 and tried downgrading to 1.0.9 but the file I got from http://web.canon.jp/imaging/eosd/firm-e/eosdigital7/download.html is not working. anytime I put the .fir file onto the SD card and try updating firmware it says that the update file cannot be found.
