Question about anti-rollback - Xiaomi Mi 8 Questions & Answers

I have first question,
Does this device have anti 4?
If yes, how is it possible for Dev to update TWRP so that the Mi8 device bypass anti 4, so it can boot to RECOVERY? Because on our Mi Max 3 forum, we have Anti 4...and our recovery Dev has yet to fix anything. I ask this forum and also just asked Note 5 Pro forum which on the list of the Anti-rollback too to see what can be done.

you just can't install any lower android versions, that's all. feel free to downgrade miui unless you are downgrading android too.

Bootloader locked by Xiaomi now, need to fill a form in Chinese and wait to unlock it

Executive summary: If you flash China Developer ROM 6.1.14 or newer, your bootloader will be locked and the root access gone.
Before you upgrade to China Developer ROM 6.1.14 or any later version, make sure you understand the implications. Turns out Xiaomi has decided to lock the bootloader and to unlock it, you'll not only need to wipe your data but file an application with them and wait for their permission. So far, the application is in Chinese only:

More details on en.miui.com in this thread:
Unlocking tool supported devices:
Redmi Note 3, Mi 4c, Mi Note Pro
Note: Forum user groups higher than Diamond member (including Diamond member), and all special teams have been added to unlocking bootloader whitelist. Your unlocking applications will be approved faster than other users.
Unlocking Bootloader Procedure:
1. Download zip file (recovery file) of China developer ROM for your device, 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
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
After unlocking bootloader, users will be able to flash fastboot ROMs and custom ROMs. The unlocked device will be marked in the official service end. Users could lock bootloader again by flashing official MIUI ROMs. (This will need to use fastboot oem lock. Please note to flash offcial MIUI ROMs, otherwise your system won't be able to start)
Notes:
1. After getting unlocking permission for a Mi account, users can unlock the verified device immediately. One Mi account could only unlock one device within 30 days
2. Users could require for unlocking permission in this site: http://www.miui.com/unlock/
3. If a prompt says that the current account is not logged into a connected device. Please log in with this account on the device that needs to be unlocked
4. If your device is encrypted, unlocking bootloader will wipe all user data. Please perform a backup beforehand
Unlocking Tool Download:
(Only Chinese supported for now. We're still working on the English version, please stay tuned.)

In other news, the root access is also gone by default and will need to be re-enabled with an online check every time you flash a ROM via recovery or fastboot (non-OTA). Details here.
Comment: It all seems a bit ridiculous., especially the online application part.
Please help and share :

Together we can change that. If unlock bootloader was easy and possible for everyone then problem wasn't exist.
What about anything from xiaomi.eu will that lock the bootloader if I flash an update through twrp?

I stayed with version 5.12.31 thus far so I don't know first-hand but according to them, no.
Just avoid the official firmware, including doing anything the Updater app asks you to. I think the app cannot be removed once installed but I posted here how to remove the notification.
Found this on french MIUI works great no locked bootloader.

hello bro,
can you give me more details about the update log?
Thanks
Had to join for change log, not found 1 problem yet.
Would go as far as to say, probably the best update since I had the mi note pro

It's totally ridiculous and the unlocking procedure is taking people a lot of time to get an answer. Very frustrating.

For an even bigger snafu, many people ended up with a boot loop after the first OTA update that also locked the bootloader, and although more than two weeks have passed there's still no way to recover from it as of yet.
This might help those with brick. No it won't ignore me.
I have received Mi Note Pro 64G few days ago
My phone is running Chinese stock rom 7.1.5 without root. I tried to install TWRP but unsuccessful.
I read some Miui forum that update rom to dev rom 6.1.28 would have pre-root but when I update to 6.1.28 via Mi-PCSuite, I still not able to install TWRP
So I read XDA forum that Mi Note Pro have to register to get unlocking bootloader code, but I can not complete the form to get unlock code
Please someone here can help me something to install a proper English rom from en.miui with google service as normal Android phone??
Thank you
Update: I managed to access the form of unlocking code request
Hope Xiaomi will process soon
I got my Mi Note Pro granted open, but i found out is was never locked. I am on Cyanogenmod at the moment. The MIUI thing was too IPhone for me (coming from an iPhone)

Works very well with mi note pro in bootloop too

Its work guys, just try ---> http://forum.xda-developers.com/mi-note-pro/help/how-to-unlock-mi-note-pro-100-t3336677
all the new mi note pro now comes with locked bootloader. one has to apply for unlock code at en.miui.com/unlock . also the funny part is that it asks for a "reason" for unlocking and if you don't give a legit one, they might reject your request. once rejected, you will have to wait 90 days for the next request. totally ridiculous but unavoidable for note pro owners.

Questions about rooting

Hello everyone,
This is my first Android device, Ive always been jailbroken and I have some doubts in Android.
I have Xiaomi Mi 8 Global Version and I want to root it.
If I root the device and I open the bootloader can I go back? I meant I read a lot of post people bricked their Xiaomi trying to relock the bootloader.
A friend of mine told me if I use magisk I could use gpay and Google application as usual, is that true?
Thanks in advanced.

ReUnlocking converted A2 (6X)

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 do you mean there is no safety way to re-lock a converted A2 which runs MIUI ?

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

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.

I see a lot of people with bricked devices, what precautions should I take?

I see a lot of people with system has been destroyed error messages, both here and on reddit. Tomorrow will be 7 days since I bought the phone and I will be able to unlock the bootloader and I'm planning to flash twrp and xiaomi.eu.
I have the global mi 9t version bought from Europe with stock miui 10.3.3. Can you please recommend me some precautions to take to avoid bricking my device? I rooted a lot of devices over the years and I only had problems with my girlfriend's Mi A1 which I bricked and had to send to a service repair. So I'm a bit nervous with xiaomi phones and especially this device since I see so many problems. Is there a specific guice for this phone Mi9t pro, or is the k20 pro guide good?

Almost all of these problems have been caused by people flashing fastboot ROMs with the Mi Flash Tool, where the ROM is for a different region to the phone. The problem happens when the default flash option of 'clean all and lock' has been used. Doing this is what causes the device to brick. Sometimes this has been done deliberately because the user didn't realise that it would brick and was trying to enable financial apps or Netflix, etc. to work correctly. Most of the time it's because the user hasn't been paying attention to what they are doing and forgot to change the flash option.
The only precaution you need to make, above and beyond what you would do for any other phone, is to check and double check, then check again that, whenever your flashing in the Mi Flash Tool, before you hit the Flash button you have changed the flash option at the bottom of the screen to 'clean all'.
If you actually do want to lock the bootloader then check, double check, then check again that the fastboot ROM you're installing is definitely, 100% the correct region for your phone.

I never used the MI flash tool, tomorrow I will use it for the first time to unlock the bootloader and the rest of the process I will do through fastboot commands. I hope everything will be fine thanks

Tomorrow you'll be using the Mi Unlock Tool.
A couple of things to point out. There is an issue with some/all versions of TWRP (not sure if they are all broken), - fastboot boot TWRP.img doesn't work, you'll end up having to reinstall a ROM if you try it, so use another method to boot into TWRP.
If you ever consider relocking the bootloader, then the standard fastboot command to do this won't work, I cannot remember if this will brick the phone or not.

I see a lot of people with system has been destroyed error messages, both here and on reddit. Tomorrow will be 7 days since I bought the phone and I will be able to unlock the bootloader and I'm planning to flash twrp and xiaomi.eu.
I have the global mi 9t version bought from Europe with stock miui 10.3.3. Can you please recommend me some precautions to take to avoid bricking my device? I rooted a lot of devices over the years and I only had problems with my girlfriend's Mi A1 which I bricked and had to send to a service repair. So I'm a bit nervous with xiaomi phones and especially this device since I see so many problems. Is there a specific guice for this phone Mi9t pro, or is the k20 pro guide good?

I have the same concerns for my new mi9t pro.
Here is an article to read about anti rollback https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/ to realize why there are all that problems and a method to see the indexes of the device and the ROM in order to make the right decision if it is safe flashing a specific ROM or not.
I don't suggest to consider K20 PRO cases familiar with the mi 9t pro, cause they have their own ROM versions specifically for China and India and that's is a part of the whole XIAOMI's anti rollback strategy.

Is there a problem with the mi9t pro global rom?
Planning to flash it on the k20 pro
That way you change MIUI region versions. That is the reason XIAOMI uses anti roll protection.
BECAREFULL. You must check the indexes of your device and the GLOBAL ROM you wanna flash

I have Chinese k20 pro and ibe flashed both eu roms and now im on global stable PIe (from android 10).
Bro just dont re lock your bootloader if you not have the official rom. Chinese or global.
If your phone is china you can relock the BL only if you flash china stock firmware.. the same you can do if your phone is global (mi9t pro).

I suppose now you can't go back because your phone's index is updated, so if you flash older ROM u will brick the device ?

How to Unlock Bootloader Asus Rog Phone 3 (06/27/2023)

I created this topic because I can't find a way to unlock the bootloader of my Asus Rog Phone 3. Regarding whether or not I unlocked it before, I would think not, since it was a high-end phone, when I bought it, it did not cross my mind unlock bootloader, root, install GSI roms, among others.
My Rog Phone 3 had Android 12 installed, I tried to Downgrade to Android 11, Downgrade to Android 10, and then use the Asus Original Unlock tool (using all its versions) without favorable results to unlock bootloader.
I also tried EDL Unbrick, although I don't know if there is any tool to unlock bootloader with EDL, tools, anyway, I open this question to see if there is any way today to unlock the bootloader of my Asus Rog Phone 3 (it has 12GB of RAM, It is optional, just in case.) Someone who can help me or access me, I would be very grateful, excuse my English. My goal is to unlock bootloader to root it and then install GSI roms, especially install GSI roms ..
