[MIUI] ENABLE "USB MASS STORAGE OPTIONS" FOR MTK DEVICES ONLY

     

Enable this mass storage options is 

really a big question till now. So here is

 one solution. I can't guarantee it will

work for all devices.

MTP file transfer is really painful. :(

Note:
I have tested on my MTK device it is working. 
In MI3 not working.

Steps:

• Download Terminal Emulator or u can execute these following commands using adb shell using your PC.
• Type "su" enter
• Then "setprop persist.sys.usb.config mass_storage" enter
• Reboot and enjoy. {:4_118:}
