How To Revert a Canon Camera’s Firmware, Method #1

That said, some who tried the method reported in the comments that it worked for them, so it appears inconsistent and may or may not work on a case-by-case basis. Once you select your pick, you can close the memory card door, and press “OK” to start the installation.Īs a note, this method didn’t work for KH Cams and stopped at 73% progress every time.

Step 3: The camera will now give an option to pick either of the two versions and you can select the older one.

As the camera displays the latest firmware version it has installed, press “OK” and instantly open the memory card slot to insert the second memory card with the older firmware version.

Step 2: Locate the “Firmware” section and click it.

Step 1: Insert one memory card with the latest firmware version into the camera and open the settings menu.

The first option involves using two SD cards. The LEAST you can expect from a US $ 1,200/- camera is to function without these issues.How To Revert a Canon Camera’s Firmware, Method #1 I love Canon but I am fed-up with this issue. Not to mention ofcourse additional expenses and 'opportunity cost' for me. I bought the unit in Dubai but live in Saudi Arabia this means I have to somehow send it back and get it back from the agent without a guarantee I will get a 'good' camera.

Shooting with Canon or non-Canon lenses or without a lens at all, shooting with hi-speed (Sandisk Extreme IV) cards, or without any card at all,in any mode (P, AV, TV M, etc) yields the SAME result. I updated the firmware and the issue is now ERR 50 but the frequency is STILL the same. I cannot fire hi-speed multi shots every time the camera grinds to a halt with ERR 99 issue.

I Bought a D 50 a little over a month ago and have had ERR 99 issues right from the start.

The D 350 has never given me ANY problems. I still several Canon EOS film bodies, and a Canon D 350 (Rebel XT).
