@tomaszchrapek , cycle thought the Info bottom on the middle left hand side of LCD screen . There should be 4 different screens , full magic lantern overlays , Canon with just a focus box and on the low bottom of screen (battery icon , Iso icon , exposure compensator meter , f-stop, lens length) , Full canon overlays , last full canon overlays with RGB exposure meters.
If you press the trash can bottom does magic lantern menu startup ?
What night build date?
