Do you want to make your bricked N8 alive again because of some tweaks or "bad" hacks? (This is not related to this issue btw)

All you have to do is to hold "Volume Down + Camera Key + Menu Key" and press power button until your phone shake.

Ps ; you may lose lost Ovi Maps and Ovi Store (Qt Runtime being destroyed during the format)
