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..
You will be able to unlock 100% within 7 days... If you have a Current account is not bound to this device error

Hi Kevin!
7 days from when? Receiving the bootloader unlock permission, since our last try or what?

Knock knock.. 50-50.. It's sometimes from the day you had permissions from Xiaomi, sometimes it's from last try. BlameXiaomi
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.

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.
i tried to unlock my bootloader the offical way, but it apears to be impossible because their unlocking tool is very buggy and keep stucking at 50%.
so im doing it the unoffical way, after using this guide for unlocking https://forum.xda-developers.com/redmi-note-3/how-to/unlock-bootloader-twrp-root-7-2-3-t3359492.
im stuck in a point where it says cant unlock bootloader because OEM is locked, i tried it 2 times while checking it is on in my developer settings.
the device now is soft-brick(i know how to get it out of it), and idea how to unlock the bootloader?
ty, and sry for my english i tend to be confusing sometimes.
EDIT:::: GO TO COMMENT 6, Solution for me was just waiting a couple of days(using legit method)

I have the same problem, I have tried countless times, but it would still show the same error, even though in the past I have performed this method countless times with 100% success rate, but now, idk why this error shows up.. I have a feeling that reinstalling the windows and then following the procedure again might solve the issue, but I dont wanna go through all that deleting and reinstalling stuff.
No need ro reinstalling windows.
Just install adb drivers and confirm u are using same sim card number in slot 1...which is used for login into mi account in phone and pc.

i have all adb drivers installed and working(downloaded the clockwork ones so they are legit working), tried putting in the sim in slot 1 same issue.
it seems like a lot of people are having issues with that bootlocker, it's a shame i was happy to buy this device and now i regret every moment
EDIT:
today it worked, basiclly the solution is to wait, shame they dont mention it themself, no need to insert the sim
This is literally the worst device I have ever had to unlock. Completely ridiculous. I have managed to get a Beta version of the Global ROM installed after hours of screwing with this thing and now I still cannot unlock it. I'm signed into MiAccount, Location is on, OEM unlocking is on, debugging enabled etc and all I is the device is connected and I am logged in and when I flash the unlock tool is tells me cannot verify device.

i had the same issue, while you read online that u should do so many stages in order for this to work. all you have to do is wait!
just take yourself 10-11 days just to be safe, (mine was unlocked after 8, but i changes from person to person).
also just checking that u do have OEM unlock enabled in your settings, and ofcourse USB debugging, and that u have clockwork adb drivers on your PC.
hope i helped, let us know if it works after a few days
this is from my thread about it:
https://forum.xda-developers.com/showpost.php?p=70484142&postcount=6
it takes time for the servers to sync, so just wait

Hello I have a redmi note 4x completely briked..the phone has the bootloader blocked, when I turn it on it restarts and never gets to load the system, I have already flash by testpoint many rom, Miui developer, Global Stable and still in the same, The phone in fastboot mode and Revory (the original of the phone) does not restart, and during the flash by testpoint it is also maintained and never disconnected, I say this because I have read some cases that this happens. At the beginning of the problem he always came to show the three points that he is loading MIUI but there is a reboot, this is not anymore the case, now it never comes, sometimes it stays on when I leave it for a long time restarting but stuck only on the logo MI .... someone knows how to solve this problem, I can not send it to any technical service or anything in my country that does not exist ... greetings
I'm no expert, but I would go online and unlock the bootloader. Then follow this: http://c.mi.com/thread-334-1-0.html There might be other ways, but this one will work, even if getting Xiaomi to unlock the bootloader takes time.
Unlock bootloader, it takes 3 days for Xiaomi to approve it. Install twrp recovery, wipe everything and install some aosp rom.

I can not do that the phone don't loader the OS..
Not sure but I think you should install adb and fastboot on pc and then Connect your phone then try "fastboot devices" and if it shows you some device, it means that your device is plugged in properly then try "fastboot oem unlocking" command this would unlock your bootloader, well the big problem is that all these commands are with respect to the Linux pc, there are something similar to do with windows and worse thing is that xiaomi have different method for unlocking the bootloader as shown in other post

Thanks for your answer, but for unlock the bootloader of a Xiaomi Phone you need first apply and ask permissions with a mi account , after that use a sofware name Mi Unlock with the account login on the phone and on the MI Unlock software. Is the only way in Xiaomi's Phone. The big problen here is I can't get into the Android System I can't put my account in the phone for unlock the bootloader.

I know that brother that's why I suggest you to use fastboot and adb as it works on some basic android phones and it is a kind of general method but I haven't tried it on mi phones

Have you tried any fastboot rom to unbrick your device, I have read your post where you have mentioned about flashing some ROMs but have not seen fastboot rom
you may use wipedata option in recovery mode, if you done have already backed up your data or you can sacrifise the data on phone,it will load the original recovery rom,than upgrade rom.....

Try flashing fastboot stock rom
I had same problem couple of days ago , i had custom rom installed on my redmi note 4 nd while i was reverting back to stock miui rom from my twrp backup i messed up nd ended up bricking my phone. I tried everything but gained nothing. In the end i tried flashing fastboot rom with mi flash tool and it worked. But i had my bootloaders unlock.dont know if it works with locked bootloader. I guess u should give a shot . Gud luck
hello .... I have a sister redmi note 4 who has a bootloop ... on the screen with the MI logo it keeps restarting .... it goes to fastboot but not to recovery ... the bootloader is locked and I still can't unlock it because what I looked so unlocked in the system by logging into my MI account ... but I can't get to the system ... I tried my flash but it says that it did something for 4 seconds and nothing still the same .... I tried to put it into download mode - by connecting contacts on the board and miflash download ROM to the phone but bootloop still continues
do you have any ideas?
the phone was so stupid that it kept restarting but always after several restarts it started but now even after two days of restart it didn't start ...
thanks sorry for my english
I had a stroke reading this.
Unlocked bootloader is the basic requirement of flashing. If you don't have it, then sorry you're out of options.
Your only option is to flash stock ROM through test-point method. DO IT ON YOUR OWN RISK.
You can find Xiaomi stock ROMs of your device here (MTK) or here (MIDO).
Of course you can always just send your device to a repair center and change it there.
Goodluck.
test point method is lint two pins od board and run mobile to download mode? I try it ... flashing was succesfull but mobile ist still bootloop

You need to flash stock ROM not any other ROM.
As in the same ROM you had before any issue. Because your bootloader is locked it will refuse to run any boot image that isn't registered in it.
If you have a backup maybe you can flash it through download mode.
I try ROMs from your link and not working...always bootloop I try a lot of ROMs - global, china, stable, weekly and not working....flash is succesfull around 190seconds.... but still bootloop

I Can't help you there mate.
Maybe there is a way to get system info from bricked phone. Maybe through a hex editor or something. That way you know exact version of the ROM you had.
So instead of that maybe you can unlock your bootloader, just request from Xiaomi unlock code with your XIaomi account and unlock it. It usually takes 30-60 days for the request to go through.
Where I find old way to unlock bootloader? because in new unlocker I unlock phone butt I must log in to my account in system... thanks

There is no other way to unlock bootloader. Unless you know a guy, know what I'm sayin?
