n97 hard reset + format

Seeing that 4.10 doesn't play (starts and it exists) i decided to bite the bullet and do a hard reset. It also gets me more system space after v20 firmware. Might as well.

As daring and impatient a person i am, i couldn't wait. I did the research and the actual reset on the side of the badminton court while i was waiting for my turn. It went well.. although since i didn't backup much, i lost all the notes, phone #, and i had to reinstall quite a few stuff.

But the good thing is after i installed 4.15 (directly. don't do 4.0 and then 4.15), everything plays fine.
