@Sven Thank you, I hope you can figure out a way!
Ironically the same thing that happened to you has happened to me this weekend. I found out that if you either
- let your phone cool down (take battery out for a while, don’t put it into the fridge (=too humid)) or
- rock on the button to left/right
sometimes the bootloop is broken and the phone boots as usual (also to recovery). I’m at the moment trying to make a nandroid backup through CWM.
In my case it is definitely the power button that is broken and needs to be replaced (Galaxy Note N7000 i9220 power button seems to work).
