Canon 5D markiii Any Manual mode broken after ML
« on: June 09, 2019, 03:28:29 PM »
Hi, not totally sure it was related to MagicLantern, but it surely started after with it (after several years of successfully using it).
It all started one day with the LED red light in the back not turning off (keeps blinking even the camera is off). I tried everything, formatting cards, changing from v123 to v113 and vice-versa, but nothing. Battery was slowly drained too.

After several attempts of installing and uninstalling ML, finally all the manual modes stopped working (nothing related to manual worked, no P mode, no M mode, either video or photo). Auto modes, and C modes works fine. Pretty weird.
My last attempt was to uninstall ML, and update the firmware from Canon website to the latest, but that didn't solve anything.

Any ideas? I have an expensive Point and Shoot now : (

Assuming it does not work even if you are starting the camera without card.

Step 1: find a good copy of your ROM (before the defect). It should be on some old ML card, under ML/LOGS. Recent versions told you to copy this in the safe place during installation, but the "several years" old ones did not.

Step 2: capture a couple of startup logs, both in working and non-working modes, using this build:
https://builds.magiclantern.fm/jenkins/view/Experiments/job/startup-log-mpu/

Step 3: also get a bad copy of your ROM (delete the ML/LOGS directory and it will be re-created).

Step 4: send me all of that stuff; I'll try to reproduce the issue in QEMU.

Questions:
- what exactly do you mean by "stopped working" ? (what are the symptoms?)
- can you still configure a C mode to act like M? (as a workaround)

Hi a1ex, i'm sorry. I didn't have the notifications on, so didn't see your post.

I tried to find an old ROM, but no luck X-/ (I also formatted my cards a few times, thinking the cards were at fault)
So, is there hope even without original ROM?

Stopped working I refer to anything related to manual settings like shutter speed, aperture, iso (this one gets automatic to "auto" every time I change the shooting mode, but can be changed to something else afterwards, but if it shuts down, then again goes back to auto). Shutter speed and aperture are always in auto now.
There is no "M" mode anymore, it goes to "C2p" mode instead of "M". "Av" mode goes to "Auto", "Tv" and "P" goes to "P" mode. And "B" goes to "C1p" as well.
So every mode related to manual settings are changed to another mode where everything is more automatic.
This is without any card in the camera.

It still drains the battery while turned off.

Hi again a1ex. I tried to find everywhere a backup of my ROM but couldn't find any ...
I downloaded the firmware for logging, and did a bunch a logs.

Very much appreciated if there is a way to make the camera work again in manual mode
