Hello,
I wonder if I am in the right section for this "I can't downgrade" question.
In my 5dmk3 I have 1.3.3 factory installed.
When following procedure to downgrade using EOS utility (1,2 or 3) I manage to go up the step at which on your mac, it tells you to "push SET on the camera to begin".
Then I briefly see the "firmware update program" window at the back of the canon.
That is briefly because then it goes black, never light again. Instead the red led of the canon battery lights up for 5 seconds, then goes out, then lights up again like that, on and on and on.
That is when I wait and I wait.... The EOS Utility has crashed or spit his waiting wheel at my face. I ask the scary question...
How do I simply shut that down ?
So I turn the camera off at some point, remove the battery to be able to put it on again.
I breathe out when I see that nothing has been damaged but my camera is still on 1.3.3
If anyone has experienced that, I'll be happy to hear about how he or she managed to downgrade that bloody firmware.
Thanks
Alex
