[GUIDE][NOOB-FRIENDLY]How to use F2FS file system

hey guys i created this guide specially for my noob grand 2 mates who want to use f2fs file system on their phones..F2FS will increase the read speed of your partition hence 'quite' faster app load up and other things too!!...sorry i am not good at writing:p so lets start!!:laugh:
*you need twrp 2.8.7.0

TWRP 2.8.7.0 :-

(2)ms01lte-http://forum.xda-developers.com/gala...overy-t3207764
F2FS info. :-https://en.wikipedia.org/wiki/F2FS

WARNING!!
*this will format all your data hence make a backup before!(in other words,you will have to make a fresh flash)
*backup internal sd on pc or somehwere else!(just in case)

STEPS:-
1)go to twrp recovery(do i need to say this?:D)
2)go to wipe>advanced wipe>select data>repair or change file system>change file system>select F2FS>swipe
3)repeat the same for cache(select cache partition instead of data)
4)now go to wipe and slide to wipe then flash rom with gapps and Boot up!!!!

WARNING!
*if you want to go back to ext4,just select ext4 instead of F2FS
*you can wipe system also but do at your own risk!!
*you can also flash stock rom via odin to get back to ext4 partition


CURRENTLY WORKING ON(as of 22/09/15):-
