Just updated mine with 5D3 and a macbook pro, no problems at all. Used a backup 16gb Sandisk extreme SD card and followed the directions. Fast and easy.

I got the error the first time (as described above). The second time worked fine. Here was my exact procedure.
The first time, I had the camera power on, removed the CF card, wrote it (and flushed it) on the PC, put it back in the camera, and updated firmware.
After this, the camera was locked up at 2978% or something so I yanked the battery. When I powered it back on, I got a message that the lens update had failed and that I should try to update it again. I removed the lens, power on just to make sure the camera is still okay, power off, put the lens back on.
Then update again and it works.
So probably, just have the camera power off, CF card in (with the lens firmware on it), the lens mounted, and then turn the camera power on and update first thing. Also, I had a formatted SD card in the whole time that I didn't touch. Hope that helps....Show more →
Had the same problem first time round. Did as you said, not sure if you took out the battery without turning it off - I did.
Then followed your procedure and it worked fine. I didn't have an SD card in. I was using a Duracell 32gb CF card 600x.

Always turn any camera's power off before you remove any memory card.
Similarly always turn any camera's power off before you insert any memory card.
Basically, always turn any camera's power off before you open the card bay door.
Curious about why, since opening the door shuts it off already. I never shut down a camera before swapping a card and miraculously avoided disaster, in more than 10 years of doing it...

You've been a little bit lucky, but most likely because you've waited long enough to let the operating system write all files to the card and update the file tables.
It also means that all the pins make and break contact with the camera off. It is much like the idea that with an external USB card reader you put the card in the reader and then connect the USB.
I don't turn off the camera to swap lenses, but I do turn it off to open the card door.

Well yes. I wait for the red light to go off first

It is not necessary to turn the camera off. CF cards are designed to be hot pluggable. The Vcc and ground pins are longer, ensuring that they make contact first and break contact last.

Turning off the camera doesn't help against card removal during write either. The camera won't turn itself off until the writing is finished. In either case, just wait until the write LED has gone off.
The LED is the only safe guide to when the card can be removed without damage.

Why do need a computer to update the lens firmware, doesn't it work from the memory card?

When you request the firmware file download, you have to select what format the file is to be in: Mac, or PC, and which version of the operating system you are running. The appropriate file is then downloaded to your computer where it is "unpacked" to the actual upgrade file the camera requires. Of course, then the computer also has to place the file on the memory card you will use with the camera to perform the upgrade. Once all that is done ... you no longer need the computer.

Yeah I've never turned the camera off. I just wait for the light to go off and then switch the card (like just about everyone else I know). I remember some of the early DSLRs actually had a little alarm that would beep when you opened the door to inform you that you should not pull the card while it's still writing.
If Datalight DOS is anything like windows (versus Linux), devices like CF cards are mounted as removable meaning writes take priority and the write cache will always be emptied as soon as possible.
Probably what happened here is that the firmware update was only tested in an older camera that didn't store, update, or have access to the battery data. For some reason, the two interfere.
BTW in the embedded world, generally, "off" is not really off. In most cases, flipping the power switch to 'off' merely puts the device to sleep, putting the SRAM and micro in a low-power sleep mode where state is retained. This way you have instant-on capability versus, say, the original Digital Rebel (300D) where after turning the camera on, you could not shoot a photo for about a second or two (because the firmware had to boot up).
So when it locked up in the firmware update, and refused to turn off even if you flipped the switch, that's why. The firmware is hung and nonresponsive to input. Why Canon didn't bother with a hardware watchdog, I don't know. Pulling the battery will power down the micro so you get a reboot when you put it back in. The only state retained when the battery is pulled is battery-backup RAM, flash, and NVRAM.
If you don't believe this, turn your camera off. Then turn it back on, and see how quickly you can take a photo: instantly (as long as your DSLR isn't really old). Now leave the switch on, but open the battery door (with most of the current Canons, this alone cuts the battery power. You don't actually have to eject the battery). Close the battery door, and try to take a photo right away. You can't, because the firmware is booting. It takes around 1-2 seconds before you can take the photo.
...I had the batteries registered so I cleared them first.
