[SOLVED] 5D2 became a brick / HELP !

[butoh]

hi guys,
a few weeks ago I bought ML 2.3. everything was ok until today. after a few hours of work (taking pictures only) I can not turn on my 5D2 again?! I charged the batteries, the camera did not even blink. what should I do with this problem? please help in this matter.

Remove the card and the battery, then start without card.

i've done it for several times. now the situation looks like this - I can turn on my camera. when I shoot in Av mode with ISO set on 500 and  then I change on Live View mode - my ISO 500 is changed on 6400. I deleted ML from my CF card and wanted upgrade firmware to 2.2.1 - I can do it but after rebooting still have firmware 2.1.1 ?!?!

Looks like it's solved. Clear camera settings and use it.

But as I said I cannot upgrade firmware and the ISO issue... What should I do? Please write me in steps

Those are different issues, refer to Canon user guide.

thanks for your reply, but I don't think 'those are different issues' ... I could upgrade Canon's firmware before I install ML 2.3 so what should I do ? you are the experts. I appreciate your massive work and also donated it. but now I've got a problem I don't think I can find the answer in Canon's user guide. Please help me to solve it

- Clear camera settings
- Do a low-level format of the card from the camera or a PC
- Re-try the updater
