Please kindly refer to the thread and read the details steps and instructions because it seems like everyone is trying to hit the unlock procedure without knowing that the stable(global) version of the ROM is not apt for the official or any unofficial unlock procedure !
PLEASE MAKE SURE YOU HAVE DISABLED DRIVER SIGNATURE VERIFICATION IN YOUR SYSTEM.
Unlocking Bootloader Procedure:
1. Download zip file (recovery file) of OFFICIAL MIUI China developer ROM for your device :
http://bigota.d.miui.com/6.12.8/miui_HM3SGlobal_6.12.8_b00ffce744_6.0.zip
Please don't get confused with the link as it's indeed a Developer ROM by 'global' in between the link and not the Global stable ROM, you can check it yourself.
Other ROM would not work. Then put it into phone storage. Go to Updater app, press the three dot on upper right corner, and select 'Choose update package'. Choose the zip file you just put in phone storage. The update will wipe all user data, please make backup beforehand.
2. Log into the Mi account which has acquired unlocking permission on your device. Make sure it's the same with the account you sent your request. It's recommended to connect to the Internet for Mi account to sync
3. Turn off your device, press the Power button and Volume - button at the same time to enter bootloader mode
4. Log into the unlocking tool on PC with the same Mi account. Connect the device with the PC using USB cable
5. Press 'Unlock'. The unlocking process will complete in about 10 seconds
For those who already bricked your devices you may using Mi PC SUITE to reflash your device.You are advised to download it to install necessary files (ADB and so on) .
Hi... as far as i know.. you need to be on the same rom from which you have applied for bootloader unlock..
i bought new redmi 3s last week.. and same day applied for unlock... and when going through different threads.. lot of people saying that we need to be in developer rom or Chinese rom to unlock boot loader..so i downloaded global developer and installed it..
with in 2 days i got confirmation from xiaomi that i have permission for unlock.. to my bad.. every time i tried to unlock boot loader its stuck at 50% with current device information is different error..
so finally decided to downgrade to the same version from which i applied for unlocking.. so tried Deep flash cable method to put phone in qualcom loader to bypass bootloader... and installed same global stable version.. after successfully installing stable version tried unlocking.. and voila... bootloader unlocked with in 10 Seconds...without any hitch...
So if you want to unlock bootloader... wait for atleast 7 days after you get confirmation message from xiaomi...

Yes, glad someone else noticed it too. Yes I had trouble for a lot of days with developer ROM after getting permission a week back but no luck.
PS: Disabling Driver Signature Verification is paramount in this process.

From my hard time unlocking Bootloader and flashing recovery until first custom ROM of 3s, I'll share some advice
- If stuck on 50% at BL unlock, >use chinese dev rom (I used this: "land_images_V7.5.1.0.MALCNDE_20160629.0000.25_6.0_cn">MiFlash has different names but it's all the same program, and if you wanna flash something, you have to run the .bat of the extracted ROM first! >And then start the MiFlash Prog. >sign into your MI account at the dev rom in your phone >activate 'find device' and all other account options there which you can tick there at login >stop account sync of the rom and start it again >go to i.miui.com and sign in >RETRY
Custom Recovery & custom ROM
- Flashing the Chinese TWRP will cause bootloop to the dev rom ! And you likely cannot boot into recovery by just a button combo, so just reboot the recovery >using recovery< once, after you had confirmed to make changes on system (at startup of recovery) >> And keep your ROM plus Gapps on your SDCARD as you cannot access the recovery easily, if not by >fastboot reflash< or working ROM (using 'reboot recovery' in it, later) ! Do not flash Gapps after you booted the ROM already, as this will cause Gapps to fail!
Enjoy~

Is it mandatory to use china dev ROM? I am on global dev. Checked the ROM zip, it contain recovery img. Its just inaccessible due to locked bootloader.

you must use this exact rom, at least this was the one i was using. and there is a guide where it says how to flash it with miflash but i lost the link. "land_images_V7.5.1.0.MALCNDE_20160629.0000.25_6.0_cn_e5777810ad" from en.miui.com
and yes, afaik you do have to flash this rom with miflash that's mandatory. chinese dev rom is must.
HOnest Solution...
Honest Solution..
If you got Permission for unlocking just wait for 6 to 10 days after getting the permission..
No matter which rom u are on..
You will unlock successfully.. Just follow the process of i.mi.com.
Well i was also facing the same issue, what really helped me here is,
1. Removed MI Account after getting unlocking permissions,
2. Re-Added MI Account by using the mobile no. (Logging in using Mobile no. is mandatory)
3. Located the phone from i.mi.com (find device option)
4. Switched off the phone and booted into fastboot mode.
5. Opened MI Unlock and logged in here from Mobile No. and unlocked.
Got success.

Sad to hear, try starting the unlock app and go offline with ur computer, and tell me if this works. this is trick of a friend
Ill try thanks
unlocked boot loader successfully . I got code week ago and i had same problem stopped at 50%.
Finally i decided to install Chinese developer rom but for last time i thought let me try unlocking again with global rom. Fortunately it was a success.
Suggestion:
- allow unlock bootloader option in developer setting.
-when ever u try unlocking.Try login with phone number ,email id and mi account code.(three try every day)
-do the same with three acc in i.mi.com(locate your phone.)
-remove finger print security.(remove security)
-And have some patients. It will get unlocked when xiomi update their database.
-i got two different codes with my email id and phone no. I don't know why i have only one account in mi.com.But if it shows u"u need to apply for unlock code "again then get it.
really frustating.
I was really surprised that I got the permission for unlocking the bootloader just 30 min after applying for request. But got stuck at 50%. Tried all solutions. I'm getting that "Current account is different from the account info on the device". Somebody please help. It's already two weeks since I got the permission. Also tried internet on/off method but no use.

1. Try removing other devices from your Mi Account for the moment, add them later if you want.
2. It takes a week or so to update your information on the Indian Xiaomi servers.
3. Make sure you're using the same account in which you got the permissions to unlock and the same account is logged-in in your Mi Account app.
4. Enable Developer options and tick "Allow OEM unlock"
Personally, I waited for 6 days after getting permissions. I was also getting stuck at 50% with a few error messages but after waiting, the unlock was successful.
I had tried a lot of things that included, switching internet on/off, factory resetting MIUI, trying multiple times, reinstalling drivers, maybe I flashed the fastboot ROM too, a few times. But after all of that, few guys suggested me to wait for a week or so, so that my device's information may be updated with my account, I did that and got it unlocked after a couple of days without any problem.

Hi,
In most cases you just need to wait a bit for the Xiaomi servers to sync up.
But, It could be your device is not being detected properly & in this case try installing the PDAnet drivers:
http://pdanet.co/bin/PdaNetA4197.exe
Install*PDAnet drivers on your PC, and follow the installation process. Even if your PC says you have ADB drivers installed, go ahead and install these. DO NOT SKIP USB INSTALL, otherwise drivers will be installed just for bluetooth, which is not*what you want. Select "other" when asked about the make of the phone.
Reboot your PC then try to unlock again.
Let me know if this works for you.

If u have got the unlock permission by sms but not able to bind then follow the instructions:
1) First goto mi bootloader by holding volume button and power button.
2) connect your phone to windows laptop
3) Goto device manager and under connected devices search for Android device... Then update the driver and now u can see it is updated to Xiaomi.
4) Use a older version of mi flash tool.
5) This will unlock your device
not working bro, on 86012 error
Where exactly are u stuck? U don't have to bind the account. Older version of mi flash tool doesn't​require it
Is it really safe to use an old version of the unlocker for the note 4 though?

Yes I guess. The newer version is just made to be compatible with windows 10 and also account binding is compulsory. So if u want to still use new version of unlock tool then good luck as u might have to wait for days, months ,year's for it to sync and bind. Haha

When I got the permission to unlock the bootloader, I didn't have time to do so. Did it after 20 days or so, and got the "86012some Chinese letters)" error. Tried everything:
1. new Unlock tool and old unlock tool.
2. Sign out from Account and sign in again.
3. Turn off find device and then turn it on again.
4. Reset the phone.
5. Updated.
And pretty much everything I could find on youtube and forums.
And then tried the last thing.
Wait for 5-10 days.
I didn't even bothered binding the Account again for 10 days.
Then attempted just by turning on 'oem unlock', 'USB debugging', 'USB debugging security. Didn't even touched the bind Account thing.
Attempted the unlock and voila, it worked.
I've unlocked 3 phones in the same way, with the latest unlock tool, without binding, each one of them showed the same error. And tried all of the above steps 1 to 5 in two of the phones. Didn't bother doing the update for third phone. And the same steps worked for each one.
Don't know what it is? But its successful everytime. Will try on more and will tell.
I had facing the same issue too, i just wait for 7 days and did nothing since the first failed one.
And after 7 days, today i tried the same way and unlocked.

The key to unlock bootloader is patience.
Just wait fr 5 days n try again yu will see d magic
guys,, i was facing same problem. I also agree that 8012... status does not matter to unlocking bootloader. I was tried all but fail after granted permission. I was tried daily. after 5 days when I tried with old mi unlock tool I got error at 50%. After that restarted my phone and clicked on settings and in developer menu, I watched i clicked on allow unlock bootloader but I forgot to click on usg debbuging. after clicked it I went for fastboot with old unlock tool and I got success. thankyou.
Try my method you will get success. hit like. stay tune. tandob is here to help you guys.
UPDATE : Okay so i finally unlocked the bootloader finally. before the last try, i turned off the password/fingerprint lock and then it unlocked. everyone should try the same thing
I done every possible steps but nothing is happening! the bootloader unlock process always getting stuck at 99% and Account Bound error is coming on the PC and on the phone, "86012:*****" error showing on 'settings-additional settings-dev option-Mi Unlock status'.
I tried with 2 different Mi phone/account.
done with i.mi.com stuffs and find device, tried FlyVPN but there is no server of 'Shanghai"... etc!
Nothing is happeneing! I am a beta tester of MIUI 9 China, and see, i couldn't even unlock the bootloader yet! Wow! What a thing! Its been a week and so, still my bootloader is locked.
No help from Xiaomi.
I need a promising way to unlock. so help me.
See, I have unlocked three RN4 devices, none without the wait.
Had to wait 6-7 days for each one of them. There has been no luck for me in doing anything other than wait for 6-7 days after getting the permission.
But then, maybe something might work out for you.
The steps I tried or know of:
1. Being on the developer ROM is a must. Chances of unlocking bootloader from global stable MIUI are very slim.
2. Use old Mi Unlock tool. A quick google will land you there.
3. Don't change the accounts in the phone. You should be logged in with the account you got permission in.
4. Go to developer options and check "USB Debugging", "OEM Unlock" and one more option something sort of "USB Debugging Security".
5. Try to bind the account. It will yield a response with some code and Chinese text. Ignore it.
6. Use the original cable and use the ports on the back of the CPU.
7. Keep "Find my device" turned on. And log in to your account in your desktop and try locating your phone.
8. Now try unlocking.
I followed all the above steps I could find out from anywhere and I was able to do it.
In your case I do think you are either not in the developer build or you need to use the old Mi tool.

After removing fingerprints and password also - nothing doing. I had applied/received unlock permission from MI on Monday, and today is Wednesday, but it keeps showing "Could not unlock after 31 hours of attempt".. Dont know what that means since from my count, it is more than 42 hours
Hello guys,it's been 3 days since I applied for unlocking my RN4 and even after getting permission I wasn't able to unlock it
Last night I got frustrated and started looking for any unofficial trick like RN3 has.... What they do is put their device in edl mode and flash a moded apps boot.mbn file and then on fastboot they execute the unlock boatloader command like fastboot OEM unlock and get a working unlocked bootloader for their device.....
I used to work as a professional DRS -digital repair specialist in reliance Jio so there we. Had a water 2 named mobile which can't be fixed after soft brick as it had the edl mode via any cable or any other process so when I opened the handset I saw those dot pinouts and tried to short them one by one and finally I got it to boot in edl mode and then flash it with qfil.....
Same as that phone... This RN4 also had those pin outs, so I opened the back and started shorting pin outs while battery was unplugged and hey yehh that let my phone in edl mode huhu ... I was happy and to test if it works or not... I got a global fastboot ROM and I wasn't able to flash it before edl via fastboot but now.... When I fired up mi flash... Set directory I was able to get it in working state (yes soft brick RN4 got life)
Than I got a twrp recovery and renamed it to recovery. IMG and put it inside of mido(RN4) flashing folder and flashed it .... But sadly even after it got flashed via mi flash I saw stock recovery...
So here I am asking for a file to get our bootloader unlocked which is emmc_appsboot.mbn
I'll upload the original file and it will be glad if some one will help me to modify that mbm file to make it unlock via fastboot.........
Let's see if people dev. Will help me or not..
Or even if some one will give me a already unlocked bootloader IMG or mbn file I'll proceed further... So plz do help me... We're soon close to get an unofficial bootloader for our beloved RN4..

Unlocking bootloader is nightmare on Mi phones. I was trying to upgrade to MIUI 9 Developer ROM from my current stable and I have to unlock the bootloader to do so. It's crazy ! I didn't have to do that on Redmi Note 3. It was easy to switch between stable and developer roms from updater app.
Anyone has any idea how can I flash the latest developer build on my Redmi Note 4 with out unlocking bootloader?

Developer Build can be installed without unlocking bootloader from updater on Redmi Note 4 also.
