Hi there, in my haste this morning i have inadvertently put an SD card with magic lantern for 550d into my eos-m instead of my SD card with magic lantern for my eos-m.
Now all I get is a green flashing light and it won't boot at all, tried with no SD card in as well as the correct SD card and I just can't get past the black screen with a green flashing light, can anyone help?
Thanks Mike
