You need the FIR and ML files on the card too.
But:
- Remove any third party accessories / batteries first
- Don't use a battery grip
- Clear canon settings and Cfn
- Run fw upgrade from PHOTO M mode (not video, photo)
Then I am hella confused!
Since everybody discribes the installation like this:
1.Format card, download 650D-safer-dump.fir and put on camera
2.intall upgrade
3.put the card back in computer and make EOS Card
4.Put ML files on card
5. Boot camera
And you are telling me that I need ML files from step number 1?
