Canon firmware update screen

Update Firmware On Canon EOS Rebel T7i DSLR

  • Adam Douglas

Recently I discovered that I cannot remove the on-screen display when recording videos with autofocus on my Canon EOS Rebel T7i DSLR. So I was hoping that a firmware update may resolve the problem. I realize some will think, the changes listed do not mention this, so why would you bother with a firmware update? Well, in my experience most firmware updates do not list all changes, so I figured why not try. I’m running firmware version 1.0.1 and the latest version is 1.1.0. So then this lead me to writing this article, as I’m sure many are not aware how to apply a firmware update.

Please be aware, as far as I know it is not possible to remove the on-screen display (autofocus) on an entry level Canon camera. Also, I applied the firmware updates starting with the version 1.0.2 and then version 1.1.0.
