Canon 5D Mark III / 5D3 / Firmware 1.3.4

[JennyGW]

dfort, great reply, thank you for all the information, much appreciated.

I just can't have the worry of what not being on the latest Canon firmware could do, so I'll hang fire for ML 135.

Would it be possible for ML to enable 4:2:2 10 bit hdmi out, do you think?  That would be so awesome.

i did the answer on the ML forum because here is the "fountain" for this information , i don't want to waste time generally in the internet from people who sometimes  don't really understand this particular   case ... from firmware 1.3.3 and over it's not the easiest way to downgrade , and specially for the last firmware i own 1.3.5 there are very few and general information for downgrading .... and because i am afraid that i might do something wrong i ask the most experienced "players" for this job .

@dfort made a very good documentation about upgrading and downgrading (Original post: Firmware update/downdate?) specifically for 5DMKIII 1.3.3 and newer releases. (I guess it works for all EOS models).

[dfort]

I do have a test build for the 5D3.134 on my downloads page but it is highly experimental and doesn't have a .FIR file. This means that in order to set the camera bootflag you need to downgrade to an ML supported firmware (1.1.3 or 1.2.3) and to set the card bootflag you'll have to do it on your computer using software like MacBoot or EOSCard. I tried doing a 1.3.5 ML port but ran into problems. Maybe someday I'll revisit this but for now my preferred ML setup with the 5D3 is using the 1.1.3 firmware and the crop_rec_4k branch.

Hallo,
is there any new news if magic lantern functions with 1.3.4 or 1.3.5?

I managed to make it work some time ago. But the card is gone and I do not have a card that is "bootflag" and I do not know how to do that either.
So I'm considering whether I go to firmware 1.2.3 and magic lantern run let.
Is there any pros or cons?

Reply #105 just above your post still applies. The 1.3.4 pull request is still open and a test build is still available from my downloads page.

Firmware 1.3.6 released.

[Walter Schulz]

Firmware Version 1.3.6 incorporates the following fix:

1. Corrects a PTP communications vulnerability.
2. Corrects a vulnerability related to firmware update.

Firmware Version 1.3.6 is for cameras with firmware Version 1.3.5. If the camera's firmware is already Version 1.3.6, it is not necessary to update the firmware.

When updating the firmware of the camera, please review the instructions thoroughly before you download the firmware.

Notes:
- Once the EOS 5D Mark III camera is updated to Version 1.3.3 (or later), it cannot be restored to a previous firmware Version (Version 1.0.7 through 1.2.3).

"is for cameras with firmware Version 1.3.5."
? I'm convinced "or earlier" is just missing. They don't really suggest to use a staged update for cams with older firmware ... I hope.

And as always with 5D Mark III after 1.3.x: Can someone test if downgrading from 1.3.6 via Canon Utility is still working?

[flostro]

I never thougt they would ever work on these old cameras again.
There was a time when Canon added features with Firmware updates,
now we have to hope they didn't "close the door" with this one.

Hello !
How can i to updater canon 5d MK3 v1.3.3 use ML  ? I havn`t found the 1.3.3 firmware , what can i do so i can use  the ML  ?

[Walter Schulz]

There are ML builds for 1.1.3, 1.2.3 and 1.3.4.
You can install any of these firmware versions by using EOS Utility (for downgrade/rollback) or just in cam (for update). See https://builds.magiclantern.fm/
If you install 1.3.6 you are stuck because there is no option available to downgrade/rollback but CPS. And not all of them are willing to do that.

1.3.6? i didnt know this one. I am still at 1.3.5 and was wondering if I can install 1.3.4 on a sd card and use it from there whilst keeping 1.3.5  OR do I have to downgrade?

[dbur]

So I don't see where to get anything after 5D3123.  Where can I get the later versions that work with newer Canon FW updates?

Thanks.

But why? Danne's builds offer more and are actually maintained.
