Can not unlock bootloader - Xiaomi Mi Max Questions & Answers

I've had the phone since March and love it, but when it updated to 8.5.1.0 it lost Root. Since then I have been unable to unlock the bootloader. Xiaomi support has been no help. I have even tried creating a new Mi account and logging of of the phone and then back in with the new account, but no luck. Mi Unlock still will not do it's job.
I get messages that the device is not eligable, the phone and account are not couples and others.
I do have to say that, other than this I do love the device. But, Again, I would like to root it again and have the option of running other ROM or flashing a new one from MIUI forum.

Proper unlock request message reason

I've read that Xiaomi my reject your request for unlock of device. I've applied for the unlock two days ago but I really don't know where to check its status? And basically there shouldn't be any specific reason why one would want to unlock bootloader unless they're trying to install third party ROM? If one writes the reason as being I would like to install Xiaomi.eu ROM on my device that Xiaomi would strait off reject it or not? Because mainly that's what I would like to do until Xiaomi releases sources (if they do) at which point many will move to other ROMs (CM etc.). So.
Questions:
What kind of good reason may someone have to unloack bootloader so that unlock will be accepted without issues?
Where can one check unlock request status?
If one unlocks bootloader and then flashes official ROM (which will likely lock it again), can one unlock it without additional unlock requests to Xiaomi?
1. I said I bought from Gearbest and had a shop rom installed and want to install original rom (which was true, but nobody can confirm this obviously)
2. I do not think you can check it
3. Flashing official ROM will not lock your bootloader again
I would suggest you wait a little more and if you still do not get a reply, open a new request or post in the forums.
btw, the request completion will be sent via an SMS message, nothing else.
1. Android Developer.
It worked like a charm, received the unlock code half an out later.

Unless you are flashing a fastboot rom with miflash and select the flash and lock radio button.
I wrote flash global rom. got the approval few hours later

I said "I want to install the xiaomi.eu rom for localization."
3 hours later they approved the request.
Thanks guys. I got permission to unlock after about 4 days. I suppose they had a bit more work after Black Friday so it took them a bit longer than usual.
But of all the reasons you're mentioned I think the best one is I'm an Android application developer. Others related to fake ROM etc. are not as viable as I'm pretty confident they know exactly which ROM you're using on which device the moment you sign in with you Mi account.

Something Emotional and Real

Device Locked

So I came back to the stock MIUI after several months due to lack of camera performance on custom ROMs. And way back the time, I've decided to DELETE my Mi Account considering that I am never going back to MIUI again. But boy oh boy, here we are.
I've flashed the stock firmware provided (links later), and I was surprised when I found out that this device was locked to an account. I've never had that problem when I switched to MIUI from LOS for about 10 days. Now that the account is now officially deleted, I have no way to activate my device even though I know my password. I've already done the following things:
1. Flashed stock ROM with different MIUI versions, and MIUI 7 and 8 are the only ROMs where activation appears
2. I've flashed the stock Philippine ROM (MIUI V5) and there are no problems with using it (I am currently using the phone for this thread)
3. I've signed-up for Mi Unlock but it was too late to know that all it does is to unlock the bootloader. AND MY BOOTLOADER IS UNLOCKED SINCE THE BEGINNING SO IT'S USELESS NOW.
4. <code>fastboot OEM lock</code> doesn't work when I try to relock the bootloader hoping that the Mi Unlock might do something extraordinary.
5. Enabled "Find My Device" on MIUI V5, hoping that the server would overwrite the existing data that's registered on my phone's serial and IMEI.
I only think of two reasons why my phone got locked:
1. The first fastboot ROM that I flashed has a locked bootloader even though it was a Global ROM
2. Still linked to my deleted account
What can I do? (except install another custom software)
Did you try flashing rom with mi flash?
I assume you have knowledge of using mi flash tool, rom images and fastboot.
Download rom images from mi website and flash with mi flash,
You might have 2-3 options at the bottom of the mi flash while you have selected the images in mi flash, 1- keep userdata and 2- wipe everything and 3rd one I don't remember.
I've don't this with my mi 4i and when I started device, it didn't ask for mi account.
Simply don't insert any SIM card and don't connect to WiFi.
I hope it might help.

Please HELP to unlock BootLoader - nothing works, looking for unofficial method

Hello there,
I've searched through all the googles and i can't seem to be able to unlock my mi 5S
Bought a half dead phone, glitchy screen and bad battery. Purchased new parts and had them installed.
Phone came with unlocked BL and lineage OS, but i f-ed it up by flashing a miui rom that locked the BL.
Then I found out the phone was actually bound to an existing MI account, so I cannot unlock it with the official tool.
Phone is in edl mode, i tried searching for an unlocked emmc_appsboot.mbn but no luck.
Can anyone please advise how to unofficialy unlock the bootloader?
I'm about to sell it for parts as I've been trying to fix it for the past week ... :crying:
Not sure if there is a way, because that way could also be used for a stolen device...
My suggestion is that you contact your seller and ask him for his Xiaomi account or that he deletes the phone from his account.
Weird thing though, the phone does not get locked if you just flash an official ROM. You specifically have to choose "flash + lock" in the official flashing application to have it locked again.

I've been emailing with xiaomi support, gave them all the details. Maybe I can convince them to remove the account.
Before flashing i was checking online on how to do it with miflash tool but i missed the radio buttons and default was clean and lock ..
After a few documents submitted through [email protected] they have removed the unknown mi account.
To conclude, I have not found any way of unlocking the bootloader except for the official way.
Also, be careful when flashing with miflash, don't lock your phone by mistake.
Ah great that it worked!

Second time with mi unlock?

Hi all,
I successfully unlocked my phone (redmi note 8 pro) Yesterday. The passages works perfectly how the officials guidelines.
But now i have a problem !!! I request unlock to downgrade my miui 12,5 to 10. But After i realized that i want MIUI 9(First rom).
The problem is that the bootloader Is still locked. I cannot add my account in mi unlock even i ll try to disconnet and add from the dedicate section in developer options.
..Hope It helps when boot phone the message Is "space archivements corrupted, device Finder corrupted. Your device Is not safe".... But device Finder works perfectly from site.
Hope in helps..
If you unlocked the phone before,you "can" still unlock it if you use your account that you used to unlock it before
Also bad news is you corrupted your persist partition which is BAD. (sensors,wifi,bluetooth and find device may not work)

Question New Device Setup Questions

Waiting for Pad 5 to arrive, in meantime was looking around and had few questions.
From what the seller posting said, it is china version with bootloader unlocked to flash global rom.
Since you need to link a Mi account to the device to unlock the bootloader, is there a way to unlink the account the seller used to flash the global rom without access to the account they used? This is just to remove the seller completely from device. (Maybe since it's already unlocked it's not needed? Idk I'm new to most of this)
Even if it's a minuscule chance of seller installing some malicious programs, is a reset through device settings enough to return it to factory/stock or is it better to re-flash global/another AOSP rom.
Thanks in advance.
Received the tablet, will answer my own questions
There was no MI account already logged in like I had thought and someone on reddit mentioned it as well in the comments. But like the store page mentioned, bootloader was already unlocked so I still think seller account was used SOMEWHERE. I think only way to fully check would be to re-lock bootloader (using china rom) then go through the unlocking process using your own account. I'm not that paranoid to do that though.
I did try resetting to factory through the settings app, no asking for password of any sort appeared liked I thought might appear (iCloud lock). In the end, I ended up flashing the latest version of the global rom anyways instead of doing the OTA update. It came with V13.0.4.0 RKXMIXM global firmware.
Now I'm trying out MIUI to see if I like it enough or I might flash ArrowOS/any of the other AOSP roms that support this tablet.
