Canon EOS M stuck on black screen! Please help!

[gabotonatiu]

I recently installed Magic Lantern (ML) on my Canon EOS M camera with the 2.0.2 firmware.

However, after using ML for a while, I decided to uninstall it. In my understanding, I believed that deleting all the files from the SD card would be sufficient to remove ML.

Consequently, I deleted everything from the SD card, assuming it would restore the camera to its original state.

However, I am now facing an issue where the camera only functions properly when there is no SD card inserted. Whenever I insert an SD card and turn the camera on, the screen remains black. I am unsure about the appropriate steps to rectify this situation.

I would greatly appreciate any guidance or suggestions on how to resolve this problem.
