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".<p>Last year's bug report:<p>https://bitbucket.org/hudson/magic-lantern/issues/2235/5dmk2-bricked-urgent-please<p>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.<p>There is no apparent way of getting rid of the BSOD, restarting your camera won't help.<p>Here are 2 potential tested solutions:<p>In both cases, the assumed starting scenario is that you turned on your camera and were shown the BSOD.<p>If you don't want to use ML today:<p><pre><code> - 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

- 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
