I have a converted A2 (+ARB 4), with UNLOCKED bootloader.
I read somewhere if you relock the BL , you will not able to UNLOCK it again ever after! (is it true?)
and other thing: If it try the MIUI BL Unlocker Official Application to unlock my device (even when it is still unlocked) what could be happen? (I've just followed the steps till the warning msg: "Unlocking Bootloader will erase user Data" ). (I read somewhere else that for unlocking miui devices you need to submit the request and you need to wait for a long time to get the code, and I was going to get the code for a case of necessity in future.)
I need to know how far I can play with these stuffs on my devices and left a practical way to recover a Bricked phone. ( I consider even TEST POINT as a practical option [tried once and it is damn easy and fun ] )
Im sorry bro but the actual model and serial code of your phone is a A2.And that means you probably wont unlock it it will give a hardware error.But pls try it and report.Dont worry there will be a fix!!

If it locked again my BL, what would be the solution? I didn't find any.
the mi unlock app requires a mi account with unlock permissions (account! not phone)
if you try to unlock an unlocked a2 you should either get unsuported - it's meant for miui devices - or already unlocked.
The app first checks the account and passes to further steps, then recognizes my phone, and warns me about wiping Data. ( At this step I declined and closed the app)
Your hypothesis seems correct, but if in any circumstances I would be left with relocked converted A2 , ist there any chance to reunlock it again?
that's why the test point method exists, for locked that you try to fastboot flash
I tried, and it just says: Device Unlocked, no need to reunlock again!
So now is it safe to lock my bootloader and try the app again?
if you lock the bootloader via fastboot commands it wont boot any more.
only way to safely lock is with miflash and you cannot miflash a wayne miui on a converted a2. it will see that it's the jasmine.
if you miflash the a2 fastboot rom it will relock ok - if the flashing works...might not cuz of the arb - but you wont be on miui any more.
what are you trying to do anyway?
i think what you dont understand is the unlock on miui and android one are the same end result but different steps. for miui you godda use the mi unlock, for and1 its just the dev options switch

So if I run the command and re-lock it by Fastboot, how can I re-unlock it again?

So do you mean there is no safety way to re-lock a converted A2 which runs MIUI ?
(and If I had a Banking app which needs a Locked BL to work, there will be no chance to run it at all?)

As I said I want to know all the aspects of practical ways to deal with my phone, right now I am totally happy with it, but actually the opportunity of dealing with all these technical stuffs convinced me to buy this phone.

I've heard that some ROMs may re-lock the phone, since then I would like to know if in any circumstances I would be stuck on that situation how can I re-unlock my phone.
any official miui rom that has the firmware folder in it might do it for example, so will bad ports....
try to use the magisk hide options to fix the banking app, add it to the list of apps for which it specifically hides root. add also the google services and make sure you pass the safetynet tests and your device shows as certified in the playstore settings. i think there were some modules to fix the bl check

So lets assume it has been happened, what would be the procedure to rescue my phone? since as you said if the BL locked again it will not boot to OS.

I would'nt like to root the phone, isn't there any other option?
if you lock the bootloader with any kind of non official rom for your phone (i.e. jasmine_sprout) which in your case is android one it wont boot. the end. only way out of that is the edl mode and miflash. that's the basic difference between locked and unlocked, it checks what os it loads and it makes sure the loaded os is the official rom for the phone. converting the a2 means it needs to be unlocked and you load a rom that's a ported miui10 from wayne to jasmine_sprout. if you flash the full rom, that has the locked bootloader from wayne which will fail to start since:
1 - the phone still isnt wayne
2- the rom isnt quite the official one (since it's renamed to work on jasmine)
3 - even if the phone was fully wayne, you dont really want the official mi 6x rom since that's china only. i.e. no google services
the only unknown in all this is the ARB, but edl should ignore that.
somehow i was under the impression you already have magisk (root/hide) up and running on the converted miui 10. yes, there are good miui 10 ports (for example xiaomi.eu) that give you the miui experience on a2 except they will never have the full ota support that the official rom has.
my advice? stick to the stock a2 rom. locked and full stock. the moment you need to start experimenting is when the android one support stops OR if you really want root.
if you wanted miui and you're outside china, mi 6x is still NOT the way to go. cuz it doesnt have an official global rom anyway. i dont get why everyone is jumping through hoops to get unofficial roms installed with stock support available.

So please consider these situations:
The phone is A2 converted to 6X &
The BL has been re-locked &
ARB 4 has been triggered
how can I use EDL mode to unlock it?
(I think miflash would not help because the LOCKED BL and the phone is actually A2)
(I think also Fastboot wont be able to unlock it since it is A2 Converted to 6X)

I'm afraid but I didt't get the point, now every week I receive Pie beta updates (besides there are stable versions too) which actually stable enough, almost Bug & Lag Free (it differs Rom to Rom, but believe me it is COOL ) , and by PitchBlack you can use direct update. (I prefer to install it by myself since I LOVE TWRP & its child PB). so what exactly we miss of original OTA service of XIAOMI?

Again I didn't get what do you mean, could you please explain it a bit more? (since my current MIUI 10.4 has almost everything)
http://bigota.d.miui.com/V10.0.2.0....0.PDIMIFJ_20181206.0000.00_9.0_02b8deeb6d.tgz this should work with the testpoint/edl method and miflash. (unless arb does something to stop it)
there's a few problems with your approach.
1) not official. any time the guys maintaining the custom rom can decide to stop producing it.
2) all work into these custom roms is voluntary. are they sometime better? sure, never said they werent but again, xiaomi/google/android have far far more resources at their disposal and while the phone is under the official period it will be maintained.
3) did you bother to read the first lines in any custom rom? they take 0 responsibility for whatever happens to your phone. they do not intend to break it, but they dont have to support you if you're in trouble either. if you dont have a valid warranty, that's understandable, you don't lose anything. but guess what? there are official vendors for xiaomi all over the world, offering official warranty. that holds as long as you're on STOCK.
4) though most custom roms are well intended, there is nothing assuring you there's nothing inside there that you dont want installed. you move your trust from xiaomi/google/android (which you can hold accountable) to whoever made that rom (who just carpet say, it's your phone you're doing the flashing, anything happens you're on your own). in most cases those devs don't mean harm, but they could and there's nothing to stop them (and they would never put in the hours of work if there was accountability for their action - i perfectly understand them. it's sortof like, i can try to do this, but because my work is not paid for by the end user they do not have any hold over me. it's correct and yet at the same time it's very very dangerous.). ever seen a custom miui built by a shop? i have, it's packed full of junk, bugs and malware. another thing here is testing. the official rom goes through a bunch of tests/beta versions. not saying it's perfect but it's better then the "known bugs: you tell me". custom rom devs cannot do it any other way, they dont have the time to test or the team to test.
5) the official devs don't have this option, they have a job and do it. it's a completely different approach.
this is not a rant against custom rom devs, i understand them 100%, they're trying to help. what i'm saying is there's always 2 sides to each story. there's no right or wrong, there's just what's best for each user. some of us will want the safe and easy way of the stock roms. some will want custom roms. in the end everyone is doing what they choose with their phone.

I think it will not work, the Actual duty of ARB4 is to preventing you to use these things! as much as I know after ARB4 you have two options: MIUI 10 or custom ROMs such as Havoc or so, for AndroidONE we need to wait a version of AndroidONE which be compatible with ARB4! otherwise flashing STOCK AndroidONE will simply brick your phone! THE whole IDEA of this THREAT is this!
And BTW as much as I know XIAOMI.EU is cooperating now with the XIAOMI ! besides we do not keep a phone for a whole life time, 2-3 years of supports would be far enough. and they do offer it right now!
and I would like to lock the BL for further security reasons but it seems to be impossible so far otherwise someone suggests a practical way for it.
I guess you need to contact me.

Just as I said, I would like to know the possible ways, currently I haven't any problem, could you explain it a bit , how could it possible to reunlock my BL if it get locked on MIUI?
ahem.
There is NO way to unlock an A2 device that has been converted to an 6X with ARB anti 4.
Your bootloaders are important in this case (xbl.elf and abl.elf). ARB and bootloader status is also managed here.
If you are using A2, with 6X system without ARB anti 4, that phone uses A2 bootloader. So if you lock your bootloader, it will brick to fastboot (The system has been destroyed / Press any key to shutdown). EDL will still accept any flashes without authentication. You may or may not be able to unlock it again through fastboot.
If you are using A2, with 6X system and firmware with ARB anti 4, that phone uses 6X bootloader. So if you lock your bootloader, it will brick to fastboot (The system has been destroyed / Press any key to shutdown). EDL will not accept any flashes without authentication*. You cannot unlock the phone through fastboot**.
*There is a workaround to this but you need to open your phone's back.
**Because MIUI devices need Mi Unlock to be unlocked, and Mi Unlock wants you to log in, and the system is not accessible, your phone will stay bricked.
You can still unbrick the phone with the above workaround, but you will be stuck with China MIUI and won't be able to unlock your phone's bootloader even if you logged in because your phone is not registered on Mi Unlock database (since Android One devices do not need/use Mi Unlock because of Google's enforcements).
Too long, didn't read?
Do not attempt to lock your phone. Even if you are on fully stock with your phone's own firmware. Locking is extremely risky due to the fact that even unlocking the bootloader corrupts the system integrity in some way.

Thanks a lot, it explains everything and totally sounds right to me,
Just couple questions:
so in any circumstances it could be again usable just with a Chinese ROM, and so there will be no way to install Google Play on it, since there will be no custom recovery , no root accessibility , ... , It will be for ever with a Pure Chinese ROM (which practically would be unusable for us). Am I right?
Considering above situation, sending the device to a Xiaomi Center could help us to get back to any kind of global ROM (AndroidONE / MIUI) or not?
Right now I am totally happy with Xiaomi.eu MIUI BETA roms, no need to switch to other projects, I need to know is there any chance to stuck with a locked BL while attempting the new Beta ROMs? I use PitchBlack to flash new ROMs every week. Or if I want to ask it in short: How to prevent to get a Locked BL?
Thanks a lot again.

Hello, I have a few questions about flashing rom just to make sure I wouldn't end up in EDL mode again. First, let me tell something. I have bought my K20 pro on Aliexpress which come with a firmware that mark as MI 9T pro with bootloader unlocked but without TWRP install. I have tried to flash Android Q beta though fastboot without using the option Flash & Lock but i was end up in locked bootloader and then i got it fixed through EDL mode by paying someone from Russia who i don't know the name. Later on, I got another bad luck again by upgrading my official Chinese firmware through OTA and then the phone suddenly shutdown in the middle of the process which break both my recovery and fastboot so i have to go through EDL again. So, my questions are:
1. If i flash anything such as magisk, viper, or upgrade my xiaomi.eu firmware through TWRP, will something like my second story occur again? Or, does flashing through TWRP will brick both recovery and fastboot in the same or similar case?
2. After EDL mode, bootloader was unlocked by default so, what can I do to bind my MI account with the device? Because in case it locked again, then I can use xiaomi bootloader unlock tools to unlock it. In the first story, the device come with bootloader unlocked, and after flashed Android Q beta, the bootloader was triggered and locked so then I tried to unlocked it but Xiaomi bootloader unlock tools told me that my account is not bind to this device.
3. If i flash magisk, then do i need to always re-flash it on every system upgrade(xiaomi eu firmware)?

1. In theory flashing with TWRP shouldn't touch the fastboot or recovery partitions, unless you choose to. If you know what you're doing, then flashing with TWRP is reasonably safe.
2. You could try flashing an official Chinese fastboot ROM and locking the bootloader, then link it to your account. Don't try and install anything else, live with the official Chinese ROM and go through the normal unlock process. Once you've waited and got unlock permission for the phone against your Mi account, then unlock and install the ROM of your choice along with anything else.
But this does come with a small risk that the phone is still linked to the sellers account.
3. I went straight from stock to a GSI, so not sure about eu ROMs. If they have an OTA process that downloads then installs via TWRP (similar to official LOS), then it's possible Magisk will re-install at the same time. Someone who uses eu ROMs will need to confirm what happens.
For anything else, you'll needed to re-install Magisk.

I believe it is a risky method because if the bootloader is locked the phone might brick again and I have to do EDL again too. I wish if there is a safer method, because I experienced EDL mode twice already and it is terrible and need to pay lot of money just to fix it. :crying:

Flashing an official fastboot ROM in the Mi Flash Tool and selecting 'clean all and lock' "shouldn't" brick the phone. If you're on an official Chinese ROM, then going through the standard unlock process "shouldn't" brick the phone.
The biggest risk in doing this would be finding that the phone is still linked to the sellers account.
If you want to be able to unlock the bootloader with your own Mi account, should it get locked again, then this is your only option.
However, you could leave it as it is and just make sure you never lock it again.

Everything went wrong today. At the end i went to the point where i myself locked bootloader with fastboot. Want to unlock it again but this strange error appeared:

Does anyone know what this means? Phone is locked, can only go into fastboot.
Same here. My dumbass thought it would be a good idea to lock the bootloader (don't ask why because I don't even know the answer). System is destroyed and can only boot to fastboot. No Mi ID associated with it.

For EDL flash you need xiaomi authorized account, there is rumors that some Indians make EDL flash with remote connection and their authorized account for 12$. Try to search in google or if you have a xiaomi seller or official repair in your home town, check there how much it will cost you.
You sure you have a global version? Were you bought the phone? Was it with locked or unlocked bootloader and what ROM was on it? Because some sellers, mostly on aliexpress and similar, just unlock bootloader on Chines devices, flash a global ROM and call it global version.
From the image attached, it looks like someone used the Find Device feature and activated Lost Mode. Is the Mi account number shown yours?

You can install any custom rom but for the warranty a stock rom must be on it.
It doesn't matter if you've tried custom roms before.

Hi Anmol150704,
What NOSS8 said basically.... You can do what you like with the phone once you get it, but for the warranty to be honoured.... you need to return it to stock before claiming or they will blame the custom rom for the issue. So as long as you device is functioning enough to return to stock, you should be ok.
And unlike Samsung, there is no Knox/Triggers that I am aware of that they can tell if its been flashed or not. Which is the main reason I came away from Samsung, due to the forced compliance to stick to stock if you wish things to continue working or claim a warranty.
Cheers, Lister
But don't worry if your phone is dead with a custom rom and of course you won't be able to reinstall a stock rom, there is EDL mode but using this mode the warranty is over (software problem only, not hardware).
By following the flash instructions and informing it beforehand, it is quite rare to destroy the phone.
Xiaomi is solid.
All clear , thanks a lot
Yes you can, I recently reverted back to stock miui 13 from Evolution X with the help of Mi Flash. All you have to do is to download Usb drivers, Your device TGZ Firmware and Mi Flash Tool. There before flashing you can select lock and clean/flash and the device will be sent to locked status once again.

Sellers buy from Xiaomi, the warranty conditions are set by Xiaomi, of course, the warranty period is different depending on the country.
If there is a beta version for your Xiaomi model, you can unlock the bootloader with Mu unlock which, as a reminder, is an official tool provided by Xiaomi.
If you buy a Xiaomi in one country because it is cheaper and you used and lived in another country, the warranty will be denied by Xiaomi.(common case where the seller refuses the guarantee and send it to Xiaomi.).
Hi Guys,
I purchsed Xiaomi Mi 9T Pro from Aliexpress with a Global Rom version but the device is a Chinese version.
The seller had to install global firmware and assosiate my device to other Mi account.
The current situation is my bootloader is locked and I can not use the Mi officially to unlock my device.
I tried to contact to the seller, but he can not assist me (they don't know the Mi account access details to release my device).
Duo to that, I tried looking the internet and found this forum. I have a good technic skill so I start tested all the suggestion the forum has to offer.
First I tried ADB and Fastboot, both are failed with the error - FAILED (remote: Token Verify Failed, Reboot the device)
I also tried miflash but he's requesting Mi account that I dont have the device their. I tried to flash a new fastboot but no success.
I really dont know what else to try, I hope someone here can spred some light on my issue from stoping my device to use as doorstops.
Thank you,

The bootloader cannot be locked to a Chinese device with a Global rom.
There is no Chinese Mi 9 t pro, the Chinese version is the K20 pro.
What is the phone model (my phone/characteristics/model)?

The device stuck on "Main Menu" MIUI Recovery 5.0 so I can not verified the phone model, but according to the seller page the model is: M1903F11A
https://www.aliexpress.com/item/33016509936.html?spm=a2g0o.order_list.order_list_main.61.21ef180253I770
I also tried to use MTK to unlocked the bootloader but I had no success to get the device into a brom mode. I can not trun the phone off, Vol+ & Vol- not works.
Is there any difference between the Mi 9 t pro and the K20 pro?
According to the model number, it is a K20 pro.
Chinese device so the bootloader is locked but with a Chinese rom since this is not possible with a global rom.
Same device except less 4G bands for the K20.
ok this is a start, any advice how to unlock the bootloader?

If the device is linked to an account that is not yours, nothing to do.
Is it a new or used device?
Check with the seller or send the phone back to him.
The device was new when I purchased it, the seller said there is no warranty on the device and he can not do anything about it. they used outsource company to do the installation of the Global ROM.
Surely there is a way to bypass Xiaomi locked on the bootloader. the Kernel can be overwrite somehow. just need to find the right way.

This model is from 2019, seems strange that Ali sells new ones.
And you still don't understand that there can't be a Global rom on this model with the bootloader locked.
The bootloader was not locked when I purchsed the device...

What you are saying now is inconsistent with your original post.
A long story to get to 'lock with fastboot'.
I'm sorry if there was a misunderstanding, here is the long story:
In 2019 I got this device from Aliexpress with a Global Rom version but the device is a Chinese version.
The phone was in English, working well with Google Play, and there was no issues with it.
In few months ago I wanted to start using Google Pay and my credit card was not approved for some reason, I contact google suppport and one of thier questions was "Have you unlocked your bootloader, rooted your device, or installed a custom ROM?"
So I started to google it, I find that my bootloader is unlocked, so I thought that I will need to lock it to be able using the Google pay service. what was found a terrible mistake.
First I understand that the only legal way to unlock it was using the Xiaomi official Mi program to unlock it. what I was found that I need Mi account with a registered device on it. my device is registered on some Chinese guy that I dont know so basically he's the legal owner of my device. so I start to look for an alternative solutions.
In my knolage with programs, I can handle with complex solutions to bypass this issue. but none of my trying wasn't succeeded. as I mentions I tried many was to bypass Xiaomi servers, now I found Miracle Box that promising to do the trick but its for only registered members. also there are some guys that said they can unlock the bootloader for money, but I dont know how trust they are....
I hope some of you guys can lead me to any idea/solution or something....
Thank you all for your time, much appriciated.

So, since 2019 you have used your device without a Xiaomi account, which severely limits Xiaomi services?
never used Xiaomi services...
Try to erase the data with the recovery or safe mode, if the option exists, but anyway if the phone is linked to an account you will be asked for the password.
Accounts are linked with a phone and email number and when you change the number a message is displayed.
Thank you, already tried it...
Is anyone know somthing about this? https://github.com/Canny1913/miunlock
Is the token is the key to success?
To sum up:
You have bricked your phone by locking the bootloader with a Global rom.
The reboot is possible but paying but when the phone reboots Xiaomi will ask you for your account and password.
Never ending Story.

Users who want to flash their phones need to study how to use tools, which ROMs to flash, etc
Eg, when flashing a ROM by Mi Flash, always uncheck relocking of the Bootloader. Then, if anything goes wrong, Bootloader will remain unlocked and one can still flash another ROM to easily unbrick the phone
