A friend updated a 5d mkii with the official update but the battery connector seems to be giving some trouble. The update has frozen and now the camera won't work.
Is there a way to fix this or will he have to send it to canon?
Best Regards ;)
Was ML installed once = cam's bootflag set?
If yes, this is the first test you should try:

I think there was no ML installed ever :-[
Not that much options left, then.
Is there any sign of life? Remove battery, remove card, insert battery and close compartment doors. LED/Screens showing any activity?
