How to Flash Mi 4 ROM

MIUI provides you different types of ROMs just incase of any software emergency. In this tutorial, I will guide you how to flash these ROMs. Mi 4 has 2 kinds of ROMs, Recovery ROM (Stable ROM and Developer ROM) & Fastboot ROM (Stable ROM it is)


Before flashing any ROM follow these 2 points :

1- Make sure your battery percentage is above 50% at least
2- Take a Back up. : Settings-->Additional Settings--> Backup & reset -->Local Bakcup-->Backup

• Backup file will be created in : Internal Storage-->MIUI -> Backup-->All Back up
• Copy this back up file on your PC or on OTG support
• After flashing Copy the back up file from PC or OTG support respectively to: Internal Storage-->MIUI -> Backup-->All Back up
• Then go to Settings-->Additional Settings--> Backup & reset -->Local Bakcup--> You will find the backup file -->Tap on it to restore

How To Flash Stable and Developer ROM.
