EOS T7i lens firmware update issues

IdahoCamoGuy — Sun, 16 Jul 2023 03:07:19 GMT

Hello all, so just today I was updating my EOS 80D and our two EOS T7i’s. Firmware updates for all three cameras went well with zero issues. I then went to update the lens firmware for both T7i’s and with the SD card in I would select the lens firmware update and the screen would go blank and then back to the menu. I could not get either camera to take the lens firmware updates at all. Any help with what might be wrong would be great. Using a Mac and the correct file and a good SD card.

thanks in advance,

IdahoCamoGuy

What lens are you trying to update the firmware on?

You may have to put the lenses on the 80D to update its firmware. Try formatting the SD card in the camera before copying the firmware file on it. Make sure that only the lens firmware file is on the root of the SD card, not the camera's firmware file also.

The standard firmware file was removed from the card and it was then again formatted. I did however have just some standard lenses on the two T7i’s and not our Canon 100-400 zoom lens. I will try later today again with no lens on the body and if that doesn’t work then I’ll try it with the lens on. I’ll report back.

When you d/l the FW and extract it there is a file included that instructs you on how to do the update. It has to be done exactly that way.

Greetings IdahoCamoGuy,

Above you indicated you would try again with no lens on the camera. You cannot update a lens's firmware unless its on the camera.

Let's ensure we understand what you are trying to accomplish.

What specific lens(es) are you trying to update?

Just FYI, There is no firmware available for the EF 100-400

EF 100-400mm f/4.5-5.6L IS II USM (canon.com)

There might have been at one time, but it does not appear to be available any longer. Link is now dead.

Canon Support | Firmware Notice: EF 100-400mm f/4.5-5.6L IS II USM: Firmware Version 1.0.7 | Canon U.S.A., Inc.

So what other lenses are we talking about specifically?

You will need to have the lens mounted on the camera. I was suggesting doing the lens firmware upgrade using the 80D camera. Whichever lens that you want to update the firmware on, has to be mounted on the camera. You will be transferring the new firmware to the lens itself, so it needs to be mounted on the camera. Once the lens is updated, you don't need to do it again to use on another camera.

Here is a link to Canon's webpage that has the firmware download for the EF 100-400MM F/4.5-5.6L IS II USM lens, if in fact this is the lens that the OP has. https://www.usa.canon.com/support/p/ef-100-400mm-f-4-5-5-6l-is-ii-usm

It is still available from that page under the software and drivers section.

So there is an update for my lens. Currently the firmware on our T7i’s is 1.0.6 and the last updated firmware is 1.0.7 as seen in the image attached. So formatted the card, put the file right in the main directory and when I select update the lens firmware on the camera with the correct lens the update screen goes black as soon as I select update.

You are correct.

What is your exact lens model? There are at least two 100-400mm lenses. This firmware is for version 2 (II) of the lens. It won't work with the original version of the lens.

The lens firmware version resides in the lens, the camera is merely displaying the version that resides in the lens. It has nothing to do with the camera.

Are you extracting the .lfu file from the download and copying that file to your SD card?

Well seeing that the update just for this one lens doesn’t amount to anything major, I’m going to forget it. The firmware for all three bodies update just fine and I’ll leave it at that. Thanks all for help. I really do appreciate it and the fast responses.

thanks again,

IdahoCamoGuy

Thanks both. Obviously, an old link. I was having a hard time believing the FW didn't still exist.

Are you able to select the file, move the selection to OK, then press the Set button? or is the screen going black when you highlight the .lfu file itself?

Re: EOS T7i lens firmware update issues

IdahoCamoGuy — Sun, 16 Jul 2023 19:11:47 GMT

As soon as I select the olde 1.0.6 version on the camera’s screen it then goes black.

Is the .lfu file on the SD card root?

Re: EOS T7i lens firmware update issues

IdahoCamoGuy — Sun, 16 Jul 2023 22:22:07 GMT

Yes just the same as the other firmware updates I did. It’s no big deal as the update isn’t a big one.
