Using F2FS:
What it is? Wikipedia

To use it you should first convert your EXT4 partitions through recovery, before installing this ROM.

On TWRP:
Download and install this TWRP version: http://forum.xda-developers.com/show...99&postcount=2
Wipe->advanced wipe
Select cache->change or repair file system->f2fs
Select data->change or repair file system->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)
Select system->change or repair file system->f2fs
--------------------------------------------------------------------------------------------------------------------------------------------------
Tips :
  • To activate Developer settings : Settings -> About phone -> press Build number 7 times
  • To activate 3-way reboot go to Developer settings and select "Advanced reboot"
  • Root is disabled by default, enable it from Developer settings - Root access
  • To disable 2nd sim on GT-I9300I add following lines to /system/build.prop :
    Code:
    persist.dsds.enabled=false
    persist.radio.multisim.config=none

Bootloop
I flashed cm12 and forgot to flash gappsso it went into a bootloop. So i went and downloaded gapps and tried to reflash everything once again but it still got me into a bootloop between bootanimation and "Android Apps updating" or something.

I'm going to flash cm11 again an then try to flash again.
Still great work @Rox

Merry Xmas!!!

I guess location app is causign bootloop. it is hard to fix if you dont have adb tool ...
I will try to make flashable zip for bootloop fix ..
For advanced users with adb:
1. Boot to recovery
2. Connect phone to computer and start console/terminal
3. Go to mount and storage and mount /system
4. Write this on console/terminal:
Code:
adb shell
rm -rf /system/app/com.qualcomm.location 
reboot

On TWRP you can also mount /system, then go to advanced -> file manager and then to /system/app/com.qualcomm.location and delete the file from there. Works for me good luck!
