MKIII failing to boot / battery issues

[adamweinberg]

hi all, new ML user here. installed a version of ML (May 22nd(240050c)) that i'm aware might not be a stable release. ML works fine when running, but 3 out of every 4 times i turn on my MKIII, nothing happens at all. if i remove and re-insert the battery, it will boot fine and everything works as expected. another issue i've had (unsure if they're related) is that i'll turn the camera off, will turn it on the next morning and the battery will be completely drained.

with these issues, i'm less concerned with solutions to them and more concerned whether or not these are warning signs of something that could potentially cause permanent issues with or brick my camera. though if anyone does have solutions / advice it would be greatly appreciated.

Can you find a way to reproduce it?

[adamweinberg]

this continually happens if i leave the ML card in the camera, turn it off and turn it back on again. i almost always need to remove the battery for my camera to boot. unless there are logs that could be helpful for developers to see, i'm planning to reformat the card and make sure i didn't miss any steps.

Teach me like you would do with a 5-year old, for example:

step 1: turn on the camera
step 2: do this and that (idk, record raw video, then use follow focus)
step 3: turn off the camera
step 4: turn the camera back on => it's not turning on.

Also post your config file.

I had the same problem.
I found the solution like this:

1.  Downgrade the firmware for a fresh file from google.
2. Restore original settings from canon.
3. Format the sd card in the computer (osx)
4. Put out the battery
5. Put all the files from other release like 17 May.
6. Apply ML firmware
7. Turn off an battery again out.
8. Make the sd card bootable.
9. Put out the CF card
10. Put SD card, Load ML.
11. Turn off, put CF card and finished.

I dont know which was the problem, but its working stable at the moment. For me was the SD card badly formatted or the firmware corrupted, i really dont know. Try with this.....

The 5D3 is sensitive to filesystem corruption; for example, at some point it was freezing at the second picture taken. Spent one hour to hunt the bug in ML, and then I've tried with plain Canon firmware - was still freezing. Formatted the card and it went back to normal.

Hey Guys,

A very simple SEARCH (see above on the menu)  will lead the answer to you question.  Search for: scripts dir missing
