"Unlocking bootloader unofficialy and officially"

First of all we need to unlock boot loader..there's 2 way to unlock your bootloader--

1.official way{recommended}

2.unofficial way{risky and kinda tricky}

--OFFICIAL WAY--

well i suggest you to use 64 bit pc because miunlock tools works well with 64bit!

STEPS:-

• first you need to apply here for getting permission from xiaomi  http://en.miui.com/unlock/ it will take 6-7 days for getting approval{open link in desktop version}

• after getting approval download adb drivers and mi pc suite setup[link down there].Intsall both.open usb debugging in your phone and connect it to pc for once.After it reboot your pc.

• after it download "mi unlock tool"[link down there] and extract zip.Open it and login with same account which you used to send request for unlocking your boot loader.after that it will show a screen like connect your phone to pc.

• now,go to settings in your phone and enable usb debugging option and oem device unlock option.after that switch off your phone and press vol- and power button until a bunny appears on your screen.

• you're in fastboot mode now connect your device with pc via cable and hit unlock button!it will take 1-2 mins and your bootloader is succesfully unlocked.

THINGS TO KEEP IN YOUR MIND:-

• You need a active internet connection for unlocking.

• If your device is not connecting when you're in fastboot mode then install drivers properly.

• Use 64bit pc{recommended}

50% ERROR ISSUE OR NOT VERIFY YOUR ACCOUNT ISSUE:-

well everything is easy huh?nope because while unlocking your gonna face 50% error issue mostly times. for fixing that follow below steps[not 100% sure thats gonna work]

• in my opinion wait for 6-7 days after getting permission bcz of mi servers.it will take sometime to upgrade their servers and add your device in list so be patient.

• try daily.never give up just try[got my phone unlocked on 6th day as well :P]

• before trying. go to i.mi.com and sign up with same account there use your phone number all time to login. locate your device from there and make sure your device is showing "online" there.

• for locating your device open your mi account in your phone and go to cloud option and enable find device.

      Submit a complaint to "nasir sk" on the link above..with ur mi uid your mi verison and unlock        tool version.

• remove all security locks,pins,patterns,fps before trying (Y)

• never give up just try daily and be patient (Y)

--UNOFFICIAL WAY--

http://en.miui.com/thread-253680-1-1.html head over to this thread.

Again im saying that unofficial way is tricky as well as risky. You can potentially brick or bootloop your device so keep that in mind before unlocking unofficially.
