Ok give it maybe another 30mins then plug it out and try to boot it up...I think it should then work...

IIRC, it should in fact boot up the moment you plug it out...If after 20seconds of plugging it out it doesnt attempt to boot up, do a boot up manually...

I would hope the above fixes it all up...If it doesn't we might have to do a reflash instead which would mean losing all your apps ...This would be the last resort...Let's hope we can fix it without a reflash
