Okay I am a bit ashamed of what I've done but I was really frustrated. I slammed my N9 and the power button against my desk to try and get the power button to try to work. And it loosened up enough for me to press it and turn it on!
Now I'm gonna try and uninstall the sillyboot and nitdroid so this doesn't happen again even if my power button doesn't work.
Which multiboot? The default nitdroid one or juiceme's ubiboot?
i was using this http://talk.maemo.org/showthread.php?t=86957
but also now i don't have nitdroid installed
and based on rikanee on irc i did turn it on by using rd-mode and force power key
