If at some point you installed Magic Lantern on your Canon camera and plan to use it today, April 1st, you're going to get a simulated BSOD on your LCD shortly after powering it on, announcing you that the camera "is bricked".

Last year's bug report:

This means that any compatible Canon camera user that at some point installed ML will be affected, if they boot with a memory card with ML installed on it in the camera.

There is no apparent way of getting rid of the BSOD, restarting your camera won't help.

Here are 2 potential tested solutions:

In both cases, the assumed starting scenario is that you turned on your camera and were shown the BSOD.

If you don't want to use ML today:

  - 1st try to turn off the camera the proper way, using the OFF switch
  - if the LCD won't turn off, open the battery door, wait a few moments and remove the battery
  - with the camera off and with no access to battery power, open the memory card door and remove the card that has ML installed on it
  - replace with empty memory card or at least one that has no traces of ML installed on it
  - put the battery back in again and turn the ON switch

If you want to use ML today:

  - 1st try to turn off the camera the proper way, using the OFF switch
  - if the LCD won't turn off, open the battery door, wait a few moments and remove the battery
  - with the camera off and with no access to battery power, open the memory card door and remove the card that has ML installed on it
  - put the battery back in again and turn the ON switch
  - go to the Canon official menu and change the date to anything other than April 1st
  - turn the camera OFF switch
  - insert the card with ML installed on it
  - turn the camera ON switch
  - you should no longer see the BSOD and ML will boot up and function as normal in parallel with the Canon firmware
