Help unlocking my Redmi 3 - Xiaomi Redmi 3 Questions & Answers

Hello Everyone,
I am posting this after a frustrating few days trying to figure out how to unlock my newly bought Redmi 3.
I have applied for the unlock, which i received about 11 days later.
Now i have been doing the following things to try and unlock my bootloader.
Currently running MIUI Global 7.1.1.0.0 STABLE (LHPCNCK)
First i tried to unlock it normally through the unlock application.
I got stuck everytime on 50% on verifying the phone,
Never got it working.
I then understood i need to install the dev rom for the unlock.
So i tried that through the download section on miui and tried to use the updater app to install it.
i got stuck at a point were it told me that the verifying of the package failed and it will not install.
Tried doing a fastboot installation but it came to a message saying that my bootloader is locked therefore i won't be able to flash via fastboot.
Please help me unlocking this.
I hate the MIUI rom it suck.
Let me know if you need any further details

Updater app can install dev rom zip. Download again, previous might be corrupted.

Here is what's wrong: Updater app only works in official ROM, and your current ROM (7.1.1.0.0) isn't one, it is a modified ROM.
So to sum it up, you need to follow these steps:
1. Flash the official stable ROM. fastboot version, using MiFlash, http://en.miui.com/thread-228048-1-1.html, (notice even if you are flashing fastboot ROM, don't go to fastboot mode, instead, to download mode) then
2. Flash the developer ROM, recovery version, using Updater, http://en.miui.com/thread-228054-1-1.html
note that developer ROM also available in fastboot version, but I don't recommend it since some had tried and resulted with bricked phone.

Well that's weird, what's your current ROM now? 7.2.7.0 yet?

I'm not OP, but I have the same problem as him.
I followed your steps and am stuck at step 2: can't verify update
I am on 7.2.7.0 stable.
Edit: turns out I had to download Dev version 6.4.21 and not the 6.3.17 that was in your link. Works now, thanks!

Yes, yes. It's not me who made that tutorial, probably he forgot to update it to newest version, one of the first thing to do when troubleshooting is that make sure you run the latest version, I think 7.2.7.0 to 6.3.17 failed because it's a downgrade, and downgrade can only be done using miflash or custom recovery. Anyway, glad it worked for you too
