Hi, i was using the magic lantern for some months with my t2i, and last night with the SD card in the screen is blank, but if i switch off the camera, then take out the battery and remove the SD card then put in the battery, then the camera works but obviously there is no card in it.And when i just open the sd card slot the screen goes blank again.
What can i do to reset the camera to the original canon firmware ?
Thanks for your help
