I did a bit of digging around yesterday and found a solution that worked for me. I couldn't get the phone past the N7000 logo - it just kept going black - even though i could hear the boot animation sound and the phone was working - only I could find any buttons that would allow me to answer the call!!
So...for an overview watch this - http://rootgalaxynote.com/galaxy-not...android-2-3-6/
I nkow this says it's for a SGH-1717 but the basic approach is right.
Then assemble your requirements:
1. You'll need to have Odin for PC on your PC (naturally)
2. You'll need to download a stock ROM - select the relevant one for your phone (not the AT&T one mentioned in the video) here - http://samsung-updates.com/
3. USB drivers for your phone - I already had them and if you've been playing with your phone and bricked ti you probably already have too!!
Then follow his instructions - it worked for me - yippee!!
