Xiaomi locks bootloader with update from 6.1.14 onward

http://www.xda-developers.com/xiaomi-locks-bootloader-on-recent-devices/
What the hell, Xiaomi?
I don't know if the Redmi Note 2 is affacted yet as it's not on the list but I aborted the update download.
Looks like it will be locked in the future anyway, so watch out!!!

Yes, and I know some of people that haven't been noticed this kind of change and their phones have been bricked ...
So the only way to unbrick their phone - reboot to fastboot mode and use line flash to recover their system.
For those who have flashed non stock's MIUI ROM => Please don't flash 6.1.14 ROM. ( But only Xiaomi Mi Note Pro/Redmi Note3/Xiaomi 4C will be suffered.)

You can flash the weekly Roms by xiaomi.eu with unlocked bootloader

It sucks but it's kinda understandable... My note 2 came from the seller with a custom rom and bucket load of bloatware... They even removed the miui browser and installed a really suspicious browser.
I flashed a new rom as soon as I could but the average user might not have the knowledge or perception of what's going on so there's a real risk here and damages the brand.
Locking the Bootloader is a necessary evil for Xiaomi, upsets the geek/dev community but protects the wider (average) consumer.
If the unlock process works as they say it shouldn't be an issue for us.

I don't like the oficial MIUI roms (bloatware, suspicious system apps, etc.). So this is a new reason to avoid official roms.

Hi!
My rn2 also came in the same state - custom rom and bloatware. I dont know what kind of a user I am but Im probably closer to average than anything else. I am trying for 'advanced' title though: ). The problem I have is not exactly flashing the new rom, at least not yet. First I want to backup the one it came with. The thing is in case of warranty claim my service center wants it returned in the state I received it in. Ive used Flashify and Partitions Backup apps first, then I wanted to boot twrp and do another backup. But it seems there is something wrong with the bootloader. >fastboot boot twrp.img works for everyone but me. It returns: failed unknown command. Do you maybe have an idea what could be wrong? Bootloader custom too? What would you suggest I do to backup my phone? I would really appreciate it.
Thank you

While I understand their motivation for locking the bootloader, and I am willing to accept it, it's the unlock procedure that is nuts. If you brick your phone, and then need to wait 1-3 weeks to get an unlock code, that is crazy. Granted a lot of people would have no use for an unlocked bootloader, and heck, don't even know what it is. But for the folks that do, and want to experiment with non-official roms or recover from a brick/bootloop, this is a real drag.
Why does the unlock procedure have to be so potentially lengthy? If you have gone to the effort to contact them about unlocking it, what's the sense in making you wait several days to several weeks to actually get the necessary unlock code? The only issue this solves is of vendors loading junky firmware--it would be discouraging for them to have to wait 3-21 days for each phone they want to infect with a junkware rom. But the collateral damage is for the end user who needs it unlocked quickly--he/she will have to suck up the 3-21 day wait. Probably a good piece of advice for anyone interested would be to immediately request a bootloader unlock code from Xiaomi after receiving a device, and then it would be available in the future when needed.

Lol Your doing it wrong buddy it's :
fastboot flash recovery recovery.img
If your recovery is named twrp.img than it should be
Fastboot flash recovery twrp.img otherwise rename the .img file and use the first command

Actually its listed as command "boot <kernel> [ <ramdisk> ]" and on RN2: hxxp://en.miui.com/thread-207290-1-1.html
Havent tried flash yet and I wont until I figure out whats going on.

Lock the bootloader, i have no problem. But at least they should have given an easier and faster way to get it unlocked.

RN2 is still not affected, still unlock on 6.1.21

I also think that Xiaomi should not do this...
BUT the only thing that concerns me about locking the bootloader is,how I am going to root my device.. The only solution would be to have a zip that contains an SU binary,properly signed so it can be flashed with Mi Recovery.
When I had the Mi3, I flashed the Global Stable,then flashed a homemade (signed) update.zip that had SU inside and I was rooted. I had my phone "stock" but rooted and could do anything..

I agree on this. I don't need custom recovery but I need root access. So stock rom (or with lock bootloader) with root access is enough for me.

So is boot loader for RN2 still unlocked in all official roms?
I have been using custom roms for last couple of months now, so I did not really keep tab on this.
TIA

yea, but just to be safe, avoid the official roms and use the xiaomi.eu roms, they are modded for international users and have the bootload lock cleared out.

My redmi note 2 pro was using the latest 6.5.27global dev rom, and I had flashed cn dev rom 6.5.27, bootloader were not locked on both rom, but since 6.5.24 there removed the native root on cn dev rom but you like the native root, just goto security app > root permission and it will let you downloaded the root package. Since then, when ever i flashed a latest rom, also flashed superSU.zip in one go by twrp.

[How to] flash Global to China Mi6 without UBL

I bought the MI6 and find out that without tools or unlock bootloader, there is no way to flash a global rom to china rom. My Mimax convenient EDL cannot be used in Mi6.
Unlock is easy, but since mine is new and under warranty, i prefer a Xiaomi rom.
Luckily i fond this tool:
https://drive.google.com/uc?export=download&id=0BwypTnSm1wlhTkp0ai1LUXZKdkk
Credit to the dev http://en.miui.com/forum.php?mod=viewthread&tid=663972&highlight=xiaomitool
Download this, run, and follow the screen.
it will check your boot, recovery, then list the rom that possible to install.
Choose global, lets it download, choose recovery and the tool do the rest.

Thank you. I will give it a try on " bricked" mi5 and new mi6.

This tool make unlock bootloader automatically... so your warranty is gone after

Ok it works

It is not working locked bootloader

Just ask for permission to unlock bootloader, usually takes a week or so. Unlock > flash > lock again. No need to experiment with some tools or whatnot official.

But my device is semi brick. My device id and IMEI are NULL. So, I couldn't unlock my device? i need know other way to unlock it.

I already had been using the phone for long enough, the permission took 4 hours to go through. Never been an active user of their services either.

Actually I am looking for a way to wipe whole partition as my second-hand mi6 is binding with a mi account which is not mine.
Flashing in EDL mode is easy to flash any official from you want but asking to unlock the device after setting up.
Though there is some tricks can be done to bypass the checking, I cannot log on my mi account or even restart device.
I had just had a tried as this thread: https://forum.xda-developers.com/mi-max/how-to/installing-twrp-locked-bootloader-t3406501
To flash TWRP directly by MiFlash. But fail to boot in it with a 'the system has been corrupted'.
Just wanna give more ways to flash or unlock with the limitation of officially unlock BL

Bootloader unlock without unlock code from Huawei

Is it possible to unlock the bootloader without the unlock code coming from Huawei itself?
I want to unlock the bootloader. Many pages on the web (and on this forum as well) say I need to get the unlock code from huawei, but... it seems that huawei is not collaborative any more: Honor/Huawei’s bootloader unlock page disappears with no explanation
Can I work it out without the code?

Actually, what I really want to do is...
Actually, what I really want to do is...: install a different firmware.
I'm a real noob in the world of modding & custom rom.
As far as I understand, unlocking bootloader is required in order to install a different ROM: is it right? or can I install it somehow even with bootloader locked? Also, can I root the P8 without unlocking the bootloader?
My P8 is on the latest firmware I recently received OTR from Huawei: GRA-L09C02B405. The phone is starting to have some problems: hight battery drenage, UI freezing and rebooting from time to time.
I'd like to install a previous version of Huawei official firmware, or different a custom ROM (I read about some of them in this forum: any suggestion?). But as far a I understand, unlocking bootloader is required, and it seems that without the code from Huawei I'm blocked

Ik zit met de zelfde vraag, ook mijn P8 kan ik niet unlocken website van Huawei met deze optie is verdwenen.
I have the same question, also my P8 I can't unlock Huawei's website with this option is gone.

You now have to contact Huawei and request it, providing IMEI, SN, Product Code, Model, and reason why you wish to unlock it.
Here is a link to contact the UK (most people say this is more successful than others) :- https://consumer.huawei.com/uk/contact-us/

Thanks @Sparkrite, I will try that way.
Can you help me also with my second post in this thread? I mean, do I have to unlock the bootloader in order to flash a custom rom and / or to root the phone?

For both, yes, you need to unlock your phone. For rooting, you have to flash a new boot.img, and for a custom ROM you have to flash the system.img too.
Without the unlocked bootloader you are unable to flash the images /partitions

For both NO, however it tends to be a bit easier if the bootloader is unlocked. Some third party rooting apps may or may not work, depending on what version OS you have installed, without changing the recovery partition.
However it is usually easier to root by flashing with TWRP etc. which necessitates an unlocked bootloader to allow you to flash the said recovery.img and then flashing SU.zip for example.
The same goes for flashing a system.img ( does not need an unlocked bootloader ) eg. use fastboot mode and an ADB shell or even DLOAD if it has the correct signatures. The caveat is that most if not all custom ROMs use a proprietary boot.img so an unlocked BL will be required in this case.
Hope that clears it up for you.

I asked Huawei for the code, now I'm waiting for reply.
So, if I understand correctly, even without unlocking bootloader I should be able to flash a previous version of an official firmware, ain't it? I can consider that option if I don't get the code from Huawei
Thanks a lot, you are being really helpful

Bootloader unlocking is not needed for upgrading official firmware, unfortunately, normally it is a completely different matter when trying to downgrade .

So, it seems that I really need Huawei help to do something more or less useful for me. They made something such a "unhackable" phone which can be hacked only with their support. And more or less every other vendor I assume.
Quite weird I think.

AFAIK Huawei are/were the only vendors that made it so easy to unlock the BL, esp. when their code generator was online.
Have you heard back from them yet, some people report getting the code within 12 hours ?

I got a first mail the day after I wrote, with them asking to add the reason for the code request.
This morning I answered them them that I wanted to play with root rights & custom rom, and that I was aware of the risks implied.
now (6 hours later) they sent me the code.
Quite a good support I'd say

You can unlock your bootloaders by using DC Unlocker.

Look and unlock bootloader with official method

In other posts there is procedure , for device with bootloader unlocked with unofficial method, for look and unlook officially, but is confused and in other arguments.
Is possible have this post for this argument, with clear guide , because I think is important question.
This maybe procedure:
1. miflash to official China Beta rom first. Flash without relock.
1b. Download from PC VPN app, install on phone and set connection to China. Then you are able to active usb developer options
2. re-lock bootloader with official China Beta rom. Flash and relock.
3. unlock bootloader again with official China Beta rom. Need to tie up with Mi account and insert a SIM card. For me, need to wait for 720 hours before MM3 can be unlocked. I checked chinese miui forum. This apparently is a new requirement. One full month later. Gosh...
4. miflash to official Global rom and stop there.
5. Do not re-lock bootloader with official Global rom""
I don't try this procedure......

What's the point of looking the bootloader just to get it unlocked again after whatever hours waiting!?
Do you experience problems with the device being unlocked unofficialy? Or this is just another "good advice/info" coming from MIUI forums...
Be happy somebody already took care of that and enjoy the unlocked bootloader freedom you get.

The device comes unlocked but your Mi account has not permission to unlock this specific device because you never followed the official unlock procedure.
Xiaomi with its new policy does not let you use a Chinese version of a phone with a global rom and a locked bootloader. If you flash the global rom and for some reason the bootloader gets locked, your phone will stuck on the recovery with the following message "this miui version cannot be installed on this device", at this stage you must unlock the bootloader to be able to boot again, if the bootloader was unlocked officialy with you own account, you can use the mi unlock tool to unlock again and make the phone bootable, if the bootloader was unofficialy unlocked or unlocked by other account, in this case you can't unlock with the Mi unlock tool, you can't flash another rom since the bootloader is locked, you can't follow the official unlock procedure because you are stuck in recovery, the only solution is to use the test point method with EDL authorized account

Ok, I guess sounds reasonable for majority of the users.
But me personally? I could care less...
You can backup bootloader unlocked status and restore it if locked by accident...

There is no way to apply for unlock without a bootable phone, He must go to Developer options -> Mi Unlock status -> Add account and device but this is not possible because the phone is stuck in recovery.
The only solution right now is to use the test-point method to flash the chinese rom.

Oh right, now I remember. This was that very big announcement. Completely forgot. Thanks for the reminder. Yes, then test point is the only option, unfortunately.
Again, this was why I urged people to steer clear of global and stick to Eu roms. More harm than good especially related to such situations (many new flashers accidentally locking bootloaders).

Thank you so much guys for your feedback, for now I have the flowing questions:

1. Hold power and volume down until boots to fastboot mode, leave it and it should turn off automatically after few seconds.
3. You can find some information scattered to the following threads

4. With the test-point method you can flash the chinese rom even if the bootloader is locked, after succesfully flashing the china rom you have to apply for official unlock, after getting the unlock permission you can flash global rom by leaving the bootloader unlocked.
XiaomiTool official page is proposing another solution but you need to wait for a global dev rom to be released and it is not guaranteed to work
If you get the message "this miui can't be installed on this device" and your device is bricked you might be able to recover it using xiaomiadb by first installing global developer and then installing china developer OF SAME VERSION (for example 8.8.16->8.8.16) using "xiaomiadb sideload_miui -otarom CurrentRom [ZIP_ROM_FILE]"

hello all, if someone can help me, i have my mi max3 with locked bootloader.
now i dont have any rom on it so trying to load a rom but getting an error ERASE is not allowed in locked state
what rom can i flash on it ?
tried to unlock bootloader via the tool, it gets stuck at 50% cannot verify phone.

had the same problem, was able to recover it with the test point method and flashing chinese rom, and switching to english language.
the procedure is described here:
https://androidfilebox.com/tips/edl-test-point-mode-redmi-note-4x/
the installation process of the qualcom drivers is special.
you have to open te backcover, which is very special too, dont forget to the 2 mini screws at the usb port and the drawer on the side . search and look on youtube.
look further, where the testpoints are on the mi max3
follow strictly the procedure, load and double extract the chinese rom for the mi max 3.
It is real work, and real danger that you break something mechanical, one shoud have a calm hand and a lot of patience, but for me all went good and the phone spang to live again.
Another solution could be this, but I have no experience with it:

Check this thread, and follow local update method, then you need only of a command to lock the bootloader:
https://forum.xda-developers.com/oneplus-6t/how-to/how-to-update-return-to-stock-oneplus-6-t3870795

I just locked the bootloader for my OnePlus 6t. Follow the steps given below.
1. Backup all the important data. I am not responsible for any data loss!!!
2. Remove security lock screen (pin/pattern) or any thing
3. Download the stock rom from https://oxygenos.oneplus.net/OnePlus6TOxygen_34_OTA_020_all_1904032212_38e22c8b9abd42e3.zip
and transfer it to your phone.
4. Boot into twrp recovery.
5. flash the downloaded zip
6. Once done, reboot the system.
7. Now, boot back into the fastboot. (you can enable advance restart from developer mode for easy boot into fastboot)
8. Run fastboot oem lock
9. You will be presented with two options on phone screen. Select the one that says lock the bootloader.
10. It will wipe everything.
11. Once you in the system, enable developer mode and make sure that oem unlock is turned off. If not, turn it off and restart your phone.
And, you are done.
Let me know if it helps or if you have any question/concern.

MDM Tool in my opinion the easiest and quickest way to go back to 1000% stock. It will re-flash every partition on the phone so it's like brand new again. Using the MSM Tool guarantees that everything is back to stock and should restore the Widevine version back to L1 or whatever it was originally.

A question please
Once you lock again your phone, does it loose the root????
I mean, I have a Xperia 10 with the bootloader unlocked , it is root as well. Now root permissions for special aps work fine, but Google Pay is unusable, it does not work anymore. I hid root with xposed framework and rootCloak, but Google Pay still does not work now because the bootloader is unlocked...
As you should know, it is possible to lock the phone again... and many of those phones that relock their bootloaders keep the root permissions...
However , in my case, with Xperia devices (bq and xiaomi happen de same) is you lock the bootloader again, the phone resets, everything dissapear and root is eliminated. What is a really disaster.
As you have heard, the majority of phones, if you lock them again the root continues working, at least the apps that you gave them root permissions they continue working as they used to. But in my case this is different....ç
So please,
Is there any possibility to Lock my bootloader again without loosing the Root in my Xperia?????
Thousand of thanks!!!!

This is the only Thread where I could find some information about locking a bootloader again. Yes , this is dedicated to xiaomi 6t, but locking bootloaders is something common.
The only thing I want is to lock my Bootloader again without loosing Root permisions. Xperia devices seem to RESET everything when you lock the booloader automatically...., but perhaps there is another way.... a possibility to lock the bootloader without the phone is reset (loosing root permissions) ....
I asked for some help here. I regret any inconvenience that could may be caused on this thread with my message.

Nobody have your phone here how could we help you? Each phone has its specific behavior
If you relock a OnePlus phone you reset everything, like when you unlock it and it's logical. A locked bootloader is meant to ensure safety of data, safety that can't be provided with root access. Locked BL and root are antinomic.

Thank you for your message and understanding. So in Oneplus devices happen the same. So once you unlock the bootloader you loose Google Pay forever because it does not work wit BL unlocked...
Some users suggested me to lock again the bootloader,
Imagine:
- I become Root. Then I modify some apps
- I give to some apps root permissions.
- I lock the bootloader again.
- I won't be able to modify my phone anymore, but all those apps that were given root permissions, Will they be kept in the phone although it has BL locked again.
would it be like this?
or all changes you did while being root would dissapear with everything?????
If So... there is no exit what I see..., We have to choose between being Root users.... or being stock with Google Pay. It is a Pity.
I was not sure if all Phones reset and erase everything when you lock the bootloader .... but as I can see here, this is the reality. Root users loose Google PAY definitely.
Is there any option to solve this??
thanks again for your attention.
regards

Does google pay work??? What did you do in magisk exactly to achieve that???
I rooted my xperia using Magisk..., is there any tutorial or info that you suggest to me to follow ? or what should I do in magisk options???
I have 10 days with my phone stopped, trying and trying to make Google Pay works....Maybe this is happening to me because my Xperia uses Android 9.0.... or Magisk should make google pay work even being in android 9.0?
First Google pay recognized Root, and the app stopped working. I hid it using xposed and RootCloak
Then, Google pay recognized Bootloader. But now... I dont know what to do to hid bootloader unlocked for Google..., Google pay recognises it is unlocked... a disaster and a nightmare for me, I dont know what to do...
Thousand of thanks, I really thankfull for your help.
