Hi all with request for help,
I am trying to unlock bootloader for 4x. I have created and activated MI-Account, downloaded and installed Unlock tool and set device in fastboot. Device is positively recognized by windows with the command "fastboot devices".
But when I start the unlock tool it checks for permissions and I get the message: "your device is not supported by mi unlock" and then it sends me back to the unlock tool download page instead of to the application page where I can put in my details. Cache of chrome browser emptied various times - no success. It´s catch 22.
I have version MIUI 8 global. I have also heard that I need to flash the Chinese/english version to unlock.
If anyone has an idea for the correct way to go from here a competent feedbck would be greatly appreciated
You have to request permission from Xiaomi to unlock your bootloader.
My redmi 4x (santoni) have twrp installed and I it is running on miui pro rom. But it's bootloader locking automatically after enabling usb debugging and switching off the phone. I can't boot into recovery and system, can only boot into fastboot mode, and I have to use mi flash tool to unlock bootloader again.
If someone face this problem, is there any solution of this. Please reply.
Thank you.
Bootloader can only be locked on all available official MIUI ROM, it can not be locked on modified MIUI versions.
There is no way that it'll get locked by itself by turning on USB Debugging and switching off phone. to lock unlocked bootloader one has to clean flash from Mi flash tools and needs to select lock bootloader before flashing.
I don't know how are you able to unlock bootloader on Mi flash tools because to unlock it official way one will need Mi unlock tool with permission from xiaomi(depending on region)
First make sure you are not on fake MIUI if so then flash official one through mi flash tools and then unlock it by mi unlock tools.
Once it is unlocked as i said earlier there is no way that it will get locked itself unless you choose to lock via mi flash tools.
about unlocking again
sorry for mistake, I have to use mi unlock tool again with my mi account signed in to unlock the bootloader again. And can't unlock by fastboot command "fastboot oem unlock".

I still do not get it what exact issue you have and what version of MIUI you are on.
You are saying you are on MIUI Pro and that confirms bootloader is unlocked and now you are saying

Please share exact and more details if you wish to resolve your issue and possibly some screenshot(s) of about phone and errors if any.

I have a similar issue and came across this thread, usb debugging suddenly stopped working, it was working perfectly till yesterday. So when I went to developer options, I saw that the OEM unlocking option is clickable now ( it had remained grayed out ever since I unlocked the bootloader ). The Mi Unlock status option tells me that phone is locked. Toggling usb debugging is not making it work. When I restart the phone, I definitely see the unlocked padlock icon on the boot screen. So I am not sure what is going on. also, magisk is working fine.
In the screenshot you can see that it shows the device is locked. But from the status bar you can make out that exposed is working. I'll have to get another device though to get a picture of the padlock icon though.

Toggle OEM unlock enabled doesn´t mean that the device is unlocked, it only means that the bootloader can be unlocked, there is other item just lines after to check it; Mi Unlock status, enter to it and confirm it.
Also, you can confirm the bootloader status through fastboot with fastboot oem device-info

Yea as I mentioned, the mi unlock status tells me that phone is locked.
Just check via fastboot, and it shows that phone is unlocked.
So do I just believe fastboot, or wait a month and then try to again unlock the bootloader via the mi unlock tool?

You said "In the screenshot you can see that it shows the device is locked" but unfortunately the screenshot didn´t reveal that, I wonder, what exactly it says in the Mi Unlock status apart.
In older days, users share an aboot image, this served to unlock bootloader automatically without make the official process to unlock it, it could be that you flashed the official stock images, and it got re-locked. Anyway, we don´t know what happened with the fastboot command or with the Mi Unlock status section, so no respond to those points.
For the part you say to wait a certain time, definitely, no, the bootloader process is not monitored any more, for older devices, they can be unlocked instantly.

My phone is about a month old, so it does tell me to wait. Contradictory screenshots attached below. After the boot unlock, I did flash flash a magisk edited boot.img and vbmeta.img to disable it. If I remember correctly though it was fine after that.
Hello. I used this method to lock bootloader in chinese version of Mi9:
in.c.mi.com/thread-1392662-1-0.html
Something went wrong and after that only recovery menu and fastboot is available. At the bottom of the screen appears a message "This version of MIUI can't be installed on this device.". Bootloader is locked now but MIUI is not starting.
I tried to unlock bootloader with Mi Unlock. Unlocking status: "Please add your account in MIUI's Settings > Developer options > Mi Unlock status." Unfortunetly I can't go to MIUI's settings because MIUI is not starting.
I was trying to force ROM installation (global, chinese, eea, stable, developer) using XiaoMiTool and FastFlash - not working.
Also I was trying to sideload MIUI using XiaomiADB - not working.
Bootloader is locked so fastboot mode is useless in this situation I guess.

Anyway help me please! Thank you in advance for any help or clue.
Just to get the background: Why did you lock the bootloader? I can't see any reason to do this after unlocking.

Because the banking applications didn't work with unlocked bootloader. I thought this is the easiest method. Now I know it's not. To be honest I was lazy and I didn't want to use twrp and magisk...

You have locked bootloader on Chines device with global/EEA... etc. (not Chines official ROM), you can't do that. As i saw in other threads there is a simple solution with authorized account and EDL flash. If it won't work the only solution is opening your device and connect some contacts with a pin and then EDL flash, there is a lot of videos about that on youtube.

Thank you g_seva. I will try that.
Oh, try mi flash tool beta first. It doesn't require you to login and use the Chinese Rom Global.
GO to recovery and use 'Mi Assistant', plug to PC, use the Mi Flash Tool (beta) if the most recent one is not working. On set it will tell you that you can't install the rom, there will be an error like you can't modify or change but you should be able to do it since you are installing an original Chinese Rom.
Give it a try first.
Hi, so I'm thinking about flashing Pixel Experience on my main phone Xiaomi Mi 8, but before that I decided to do some testing on my old phone Xiaomi Mi 5. Flashed the ROM without a problem and the first thing I wanted to try is if my bank app would work without hiccups. I could connect to it without problems, but whenever I try to enable biometric log in, I get this message „This service is unavailable on a device with OEM unlocked in Developer options“. As I understand, it's talking about the Bootloader being unlocked, strangely enough, bootloader is unlocked on my Mi 8 and I don't get this message. I went to Developer Options on Mi 5 and I can't even see the OEM Unlock option, and no, neither devices are rooted.
Any suggestions?
Strangely enough, don't have this problem on Xiaomi Mi 8. So I guess it's solved.
Hi all
I had unlocked bootloader before but I was mucking around with mi flash tool and accidentally locked the bootloader.
Now the mi unlock tool isn't unlocking the bootloader anymore. Its giving an error "Couldn't unlock. Please add your account in MIUI's Settings".
I have tried everything, added the account in settings, then bound the account in "Mi Unlock status". Repeated it a number of times. Updated USB drivers, used two different machines, verified SIM connection via Mi Cloud etc but it just doesn't work unfortunately.
Is there any other method that doesn't involve mi unlock tool? Any help would be appreciated. Thanks.
