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.

does flashing a MIUI.eu beta ROM without deleting the firmware folder lock the bootloader ?

Hello all,
Yesterday I received a k20 pro from china with an unlocked bootloader.
I wanted to get rid of the spy/bloatware so i went and tried to install twrp to install another ROM, but for some reason TWRP flipped when i installed it (i think i forgot to turn off encryption) and just decided to stop working altogether. Recovery did not work anymore and so i was stuck in fastboot (bootlooping). After some stressfull googling i found out, the only way to get the phone working again is by flashing the (only) fastboot ROM, which was the chinese variant.
I was so stressed out, i forgot to change the flash option in xiaomi flash tool to "clean all" instead of "clean all and lock"(which is the default, fu Xiaomi).
So now my phone has a chinese ROM and the bootloader is locked.
So my question is:
Once i get the bootloader unlocked again (which will take 1 week hopefully), will i be able to install the global ROM (once it is released) or a better, a non-spying ROM?
Also, i tried debloating the chinese rom, but everytime i apparently debloat too much and the phone just stops working and i need to do a reset.
Does anyone have a proper list of xiaomi applications that are safe to remove (trough adb)? the ones i found remove too much.
Thanks in advance.
Yes, once you unlock your bootloader again, you can flash indian global firmware, which has less bloats, google apps and services included, and poco launcher.
For debloating cn rom, there is a tool here, I'll find and link.
May use this for debloating- https://github.com/Saki-EU/XiaomiADBFastbootTools

Hi, this is the program that i've been using for removing the xiaomi apps, however when some of the listed apps are removed the phone won't be able to restart anymore and i have to do a reset.
For now, i manually removed all the removable spyware by hand and installed blokkada to deny communication to xiaomi servers. I don't dare to remove a lot of system apps trough adb anymore since i had to reset my phone 5 times already... i just want to use it now...
Just endure the pain until bootloader is unlocked again then move over to the Indian rom, its much more tolerable.

This is the safest option. Whilst waiting for bootloader unlocking I just uninstalled anything that could be and disabled anything else that could be disabled. There were still many things I wanted to remove that could not be uninstalled or disabled, but decided I could live with them for a week.
After your week is up, you've got many options. If you like MIUI but not the bloat and spyware, then there are MIUI custom ROMs that remove the junk, xiaomi.eu ROMs being one of the biggest. Otherwise there are AOSP based custom ROMs that are stable enough to use.

NO.
If you try and lock the bootloader with anything that is not the original region you will hard brick the phone.
If you have a Chinese phone, then you can only lock the bootloader when installing an official Chinese ROM.
I think only the account used to unlock the blootloader can relock and re-reunlock it.
If you lock the phone, you won't be able to unlock it again with another account.
It is just a safety mechanism from xiaomi.

You don't need an account to lock the bootloader.
Provided that there is not a Mi account linked to a phone, then anyone who has the phone in their possession can unlock it.
When people have bought a phone already unlock, then accidentally locked it, they have been able to unlock it themselves if the seller has already unlinked the phone from the sellers Mi account

So basically it is possible, if one gets a k20 pro flashed with global rom, that if the seller forgets to remove his account from the phone, you're stuck using ONLY other roms? In other words, in order to relock the bootloader and install official chinese rom, you need to contact the seller and ask him to go on his mi account to remove your phone?

Yes there has been a few cases on these forums where this had happened.
However, you can still use official MIUI ROMs, you can still flash the Chinese ROM and lock the bootloader. The problem then is that you cannot unlock the bootloader again if the phone it's still linked to another account.
If you buy a Chinese phone with a global ROM, why would you then want to flash a Chinese ROM and lock the bootloader? You would be better off just buying the phone still with the Chinese ROM and locked, if that's what you wanted.
People have had problems because they've been flashing an official ROM with the Mi Flash Tool and accidentally left the flash option to flash and lock. When flashing with the Mi Flash Tool you just need to remember to change the default flash option every time you use it.
If you never relock the bootloader, then you will never have this problem and can still use official MIUI.

I'm not sure what you're asking. I'm guessing pscotes is a typing error.

On AliExpress on almost all listings on Huawei devices (P20 Pro for instance) there is the option to buy it with a flashed Global ROM. And they do this without unlocking the bootloader.
How do they do it? Is it that the bootloader on the Chinese version is unlocked?
For example...
https://forum.xda-developers.com/huawei-p20-pro/how-to/guide-force-update-using-firmware-t3963074
This is just a stock rom, you can download an update.zip and install it via recovery no problem.
Don't make the mistake of thinking this is a custom rom like AOSP it isn't.
It's completely stock, all P20 Pro devices come with an open OS afaik, then when you turn it on with your SIM it binds to the carrier / location, least that's my understanding of it.
But 100% not a custom ROM.

What do you mean by an "open OS"?
My Huawei device has a locked bootloader, and I didn't find any way on the internet to unlock it yet. (There is a site that offers leaked unlock codes from Huawei itself for 50$ but I won't pay this much). Consequently, so far I've only been able to install official Huawei ROMs only.
*Huawei has stopped to officially offer unlock codes since a year as of now.

You don't need to unlock your bootloader, look for the otg update method on xda.
It's quite easy.
Open OS, as in its just a stock ROM. Nothing more.
Mi 9t Pro global Rom Miui 10, android 9.
will flash K20 Pro india ROM miui 11, Android 10 fastboot.
why all recommend keeping bootloader unlocked?
i don't want the hassle of banking apps and use Magisk. so what's the problem here of re-lock bootloader after flashing the new ROM?
technical details are most welcome.
Locking bootloader with a different ROM region installed will brick your device. Unbricking will require further wait for bootloader unlock time or you'll need EDL method which I'm not very aware of how it's done.

why locking bootloader with another region rom installed will brick my phone?
and what you mean by brick that it'll never boot?
i got below reply from reddit, what do you think about it??
You are flashing a different version of MIUI. It's not what a lot of people call a ROM (although you are technically correct) . It's not like if you flashed a third party ROM like Lineage or xiaomi.eu... You can relock the bootloader if you have an original xiaomi system and recovery and did not modify your bootloader through a rooting tool (such as having Magisk installed as they get installed and run through a procedure called k-exec that patches the bootloader instead of the system so the hack is unknown to the OS).
Bootloaders are locked to prevent tampering with such exploits. Magisk is not malware but malware and spying tools can be implemented in the same way.
When the bootloader is locked only a ROM and a recovery made by the company that makes the phone can run.

I am not sure about that now. But it bricks because that's how Xiaomi have put. I may be wrong but if many people are saying the same then there should be a reason.

With official ROM either Global MI, Global EEA or China, with Xiaomi MI Flahs tool you can block the bootloader without any problem.
If you do not usually change the rom, or to custom rom or recoverys custom, it is advisable to block it since you cannot download netflix from the play store and some bank applications mark errors. Otherwise you can unlock the bootloader.
The most important thing about keeping it unlocked is that you lose the equipment warranty.
And the benefit of having it unlocked is that you can change from rom or custom rom, and you don't have to wait for xiaomi time to unlock it again; but lose the warranty.
But you open custom possibilities.
thank you guys, but i really need to know what is exactly meant by hard brick?
is it not to boot again or what??

Hy!Are you sure that if I own an Chinese variant of k20 pro and if I relockmy bl I won´t brick my device by relocking it?I just unlocked it today and I plan to instal the EU rom and relock my bl.
Just to make it clear...
Chinese K20 Pro needs to have Stock Chinese rom if you want to relock the phone! Without Mods or anything. Just clean Chinese firmware!
The same for indian variant. Only indian firmware without mods.
Also for Mi 9T Pro! Stock rom without mods!
Even TWRP isn't allowed If you wanna relock the bootloader!
If you cross flash roms and relock the bootloader you will brick your device! Your phone won't boot! You will need to open the backcover and boot it into EDL mode and blablabla. There is a thread about that.
Can be found HERE!
Hi all,
is it possible to unroot the device, maybe through flashing stock firmware, and then use GPay as before rooting it? Even if the bootloader remains unlocked?
Thx in advance

How did you root it? Google Pay works fine on my rooted phone but there's a couple steps to get it to work.
It does work, but I want to sell my Mi 11, because I got a Mi 11 Ultra for not too much money. So I want to flash the original Software on the Mi 11 again. The question is, if GPay will still work after that.
I rooted it by converting the Boot.img file with the magisk app

Not sure. I don't have any experience with just an unlocked bootloader. I always have root along with it. Why aren't you locking the bootloader as well? China Variant? Usually, it makes more sense to lock the bootloader as well if you're selling it ?
It's the german variant. Isn't it risky to relock the bootloader?
There's no relocking risk if you flash the stock firmware beforehand.
Ok, thank you
Ok, thank you
I've tried before with several Xiaomi devices before Mi11 (mi8, mi9, poco x3 nfc and pro), but it surely works.

It's risky to lock with a different regional ROM on them. The only one that I know for sure about is the China variant of the phone which can only be locked with the OEM china firmware. The original ROM the phone came locked with is no risk at all. It might also be that the China variant is an outlier because they're not allowed to have GAPPS there.
