Please help, how to uninstall? (5D mark2) video added! [Solved]

[a1ex]

After you will read Canon's manual, these buttons will start working again... by magic

I do not have a 5D3 but I  suppose you already restored the camera and Cfn to their default values, right?

Oddly enough, restoring default settings on 5D Mark II and 50D will disable LiveView. ML install guide explains this.

Its silly as ML advise to format the card  by pressing PicSel button(to remove ML from the card) and then to remove any trace from the camera itself you actually need to put the ML firmware back to the memory card  to run installer!!!! where is the sense?? very annoying!

from the INSTALL.PDF:

Uninstalling ML from one card
* Format that card from the camera (select this option: Format card, **remove* Magic Lantern*) and reboot. Your camera will load the original firmware when you use that card.

Uninstalling ML from the camera
* With a Magic Lantern card, launch the Firmware Update process and follow the instructions on-screen.

i have no idea what we should do about that. this is de facto the way it will work and has to work.
if you know a better way, feel free to join the development team and improve the installer routines
that access BOOT ROM or hack some routines that rewrite the flash from main firmware.


and about the defect dial that prevents you from uninstalling ML... well.... this is nothing that ML caused or where ML did smth wrong.

try resetting canon config to default, maybe you shut your camera off in middle of a bracketing sequence or similar.

Thanks guys for all your comments. For some of you things are obvious but for most of the users message like for example "Bootdisk flag ENABLED" means nothing and sound like I have to spend another couple of hours "googling" what does could mean... For me if something is disabled means that it exist but is switched off/not active.. so I was assuming that ML or its remains are still on the camera but disabled somewhere in the bootdisk file or maybe there is now extra file somewhere in camera ROM that prevents ML to boot from the card... a mystery
As I was just about to take my 5d for the repair I was getting annoyed.. maybe to much
Anyway I took my 5d to repair today:( I can only hope they will not charge me hundreds of pounds...

You are right a1ex, LiveView button was disabled after restoring default settings! but both dials (on the top of the camera and on the grip) are dead. I am sure it is nothing to do with uninstalling ML but it happened right after uninstall so I was confused.

Last question  .. : after uninstalling/disabling ML from the camera and burning the memory card will the canon service technicians know that ML was installed?

[ilguercio]

I bet most camera services couldn't care a thing if you installed it, they aren't really going to check for it. Yes, technically they could, setting the bootflag changes something permanently) but as said somewhere else they don't have a reason for doing so.

There are several ways to uninstall Magic Lantern on the 5Dmark 2, but none of them worked for me. None of the solution on Youtube worked. The green text did not show up, and it was not possible to use the menu on the camera to update or format the card so ML could disappear. The solution was to install ML again to the CF card: I created a new folder on the PC. Here I uploaded all the files from the ML -> "Download Magic Lantern -> Stable Release: v2.3" to the new folder. So I transferred the ML files to CF who stood in the PC. When the PC will ask if any of the files on the CF card Schall be replaced? (since they are already there) Answer yes to all those questions. Insert the CF back in the camera and turn it on. Then the green text will up and ML can be uninstall, as shown in many yotube uninstall guides.

This is so true. I am on ML nightly build on a 5D2 and when I click on the Canon firmware update button, nothing happens.
So I just have to format a new card and load ML v2.3 onto it and then click the Canon firmware update button. This time, I was
able to see the ML screens and reset the boot flag.  Thank you for the tip Geir!
