It definitely works. All you have to do is download the file, rename it to framework2.jar and then replace with yours under system/framework. Then reboot immediately. Copying it using Aroma file manager is more reliable.It didn't work for me.
It only works for one time and If I turned the wifi on the second time it just crashes or freezes.
Could you please tell me the steps you've made step by step
If it didn't work in this way, you'd rather consider trying on another ROM.
SENT FROM WHATEVER IS NOT SOMETHING TO BE LOCKED AT, THE THING IS THAT IT IS SENT.
