Android Smart phone Unlock Bootloader, root and flash rom

I would like to write down my experience of unlock bootloader, root and flash the rom for my sony xperia U and my understanding in a matter of kernal, tools and so on.

Before this, I would like to list out all the useful links which help me to finish the tasks.

However, time is limited, I would like to finish it tomorrow morning within 1 hour. Thank you.
