*This is not my work, Just a copy and paste from http://sxtp-forum.com. Which seems to be down/gone/wiped now. I managed to get a copy of it so i posted it here for reference. I know i could have reworded it and called it my own. But thats for noobs. Credit for it should go to the proper people.
I can confirm that this works. I personally tested it. My phone went back to Unrooted, stock kernel and factory fi22 rom.
