This tutorial will teach you how to restore your Redmi 2 to a perfectly working state when you soft brick your device.
A soft brick may be a result of flashing the wrong ROM, wrong recovery image or accidently messing with system files which should have been left alone. And a soft brick does not require you to head over to the service center because you can fix it in under an hour. So without wasting much time, lets get on with the tutorial.

- A Computer running windows operating System (Win 7 preferred)

- If some driver fails during installation or you dont see any device on miflash , check device manager for any driver not installed properly and install it manually and browse the driver from /programfile/xiaomi/miflash/qualcomm/ "here" .
- If miflash gives some error like reached end of fie, receive Hello packets, give the pc a reboot , but be sure to again press f8 and disable driver verification. Is still problem persists, do try another pc running XP or windows 7.
- If you face any problem with driver installation - make sure you disabled driver signature detection while booting windows by pressing F8.
