PART 1 - UNLOCK DEVICE AND FLASH TWRP
# Before starting, be sure that you can unlock your bootloader and you have these files: #
- Mi Unlock tool (http://en.miui.com/unlock/)
- Minimal ADB & Fastboot 1.4.3 (https://xdaforums.com/showthread.php?t=2317790)
- TWRP recovery for your device (please check the development section).
Install ADB and Fastboot drivers on your PC, if you don't have them already.
- enable developer options on device, allow OEM unlock and ADB debug.
- install Minimal ADB & Fastboot tool and run a command window. PLEASE DON'T USE WINDOWS 10 POWER SHELL. Double click on "cmdhere.dll" in root folder instead.
- move twrp image in the same folder where Minimal ADB & Fastboot is installed.
- for your convenience, rename twrp file as "twrp" only.
- connect your device to your PC USB port, pair it with PC then reboot it to bootloader (power + volume down combo).
Unlock bootloader using Mi Unlock tool (full unlocking guide at https://c.mi.com/thread-1635834-1-1.html)
Unlocking bootloader will erase all of your data, including storage.
Once you unlocked:
- reboot and setup device
- enable developer options again
- double check bootloader status and allow ADB debug
- connect to USB port and pair device with PC for ADB debug bridge then type in command window:
Code:
adb devices
Code:
adb reboot bootloader
Code:
fastboot devices
Code:
fastboot flash recovery twrp.img
- swipe to allow twrp modifications.
- I would suggest to NOT format data to get rid of encryption unless you actually need it. Encryption does not slow down your device or harm your battery life.
- I would also suggest to NOT wipe system and reboot to recovery because it could lead to a fastboot bootloop.
