possible solution to "Format card, keep ML [Q]" on 550d not toggling

[pendal]

I installed ML on my 550d today but when tried to format SD card, it's not possible to toggle between "Format card, keep ML" and "Format card, remove ML" using Q button.

It just doesn't work on 550d, as discussed here : https://bitbucket.org/hudson/magic-lantern/pull-request/575/restore-after-format-refactoring-fix-for/diff

The solution for 1100d and 600d was to use BGMT_Q_ALT. I don't know what that is. and I have programming background, so can anyone point it out to me?

Finally, here's my solution, I haven't tested it yet, wanna know if it'd work first,

BOOT the camera in original firmware using SET button, then you can Format the whole SD Card without keeping ML. <- Would this formatting reset boot flag too?

Thanks

It's a constant (macro) that represents a key code. Just look at the diff on bitbucket and see how it was changed for 1100D and 600D.

650D is also not confirmed, does it work?
