[UPDATE 01/02/16] WARNING: Locked Bootloader

[ice-it]

I have great problem now!

I bought my Mi4C some months ago, and I flashed the dev rom at the beginning, using the built-in root function.
I was using it happily, until one day, after flashing a new rom, I found that there is no root anymore.

So, I followed the instructions, apply for unlocking the bootloader.
After 3 weeks of using the phone without root, I got the unlock code finally.

Then I found that it's a nightmare.
I am in a deadlock.

To unlock, I have to sign in Mi account in the phone.
However, I have frozen the Xiaomi services already when I first used the phone.
Now, I don't have root permission to unfreeze the Xiaomi services.
So, I cannot sign in my Mi account, unless I hard reset my phone.

I find this really ridiculous!
At the first place the phone was not locked.
Suddenly it is locked, and I have no way to unlock!

What is the best way to solve my problem now?

Root procedure have changed since 6.1.14, but you can still have root with locked bl, have a look here http://en.miui.com/thread-185414-1-1.html

My problem:
1) Go to "Security - Permissions - Allow ROOT Access", it tells me that, I have to unlock fastboot first (i.e. unlock bootloader).
2) I have though of flashing SuperSU, but I am not able to boot into recovery mode. (Pressing Vol+ & Power button to boot leads me to fastboot mode(?))

Any solution?
Thanks.

Sorry, I was thinking that root was independent from locked bl...
Anyway if your phone is working, simply flash the official stable ROM by updater app to unlock the bl or follow this http://xdaforums.com/mi-4c/general/mi4c-flash-twrps-recovery-cms-row-t3307801

It's a close enviroment.... like apple id, etc.

I find it normal to make use of UID (unique identifier data) to be able to lock or unlock boot loader.

En.miui.com being an official forum from Xiaomi, it is normal to be active there, not in 3rd party forums. Unlike HTC, Samsung or other big players.. they have a forum...
