First of all, i apologize for my bad english.
this method will help you to unbrick your Mi Mix 2s!
from :
1. The system has been destroyed
2. "This MIUI can't be installed on this device"
3. Locked Bootloader in global/ china ROM
4. Etc
how to do :
1. Remove the back panel of the phone
2. Do test point #below the rear camera
3. Flash it with MiFlash2018-5-28-0
*before you flash, go to MiFlash2018 Folder -> Mi -> account_auth.exe
login with Authorized Mi Account (thanks for redmi note 5/pro ARP cases)
4. do flash
5. wait for done
6. enjoy ur mi mix 2s again!!!
Basically everyone on the official Xiaomi Support Threads for the Mix 2S says this does not work. Not almost everybody--every single person that has tried it and left a comment about their experience. All you will do if you follow these instructions is permanently destroy your phone and if that is your intention smashing it repeatedly with a hammer is faster and easier.
Sorry, I did for my phone, and it's works
And now I am replying from my mix 2s,
It was bricked XE model with locked bootloader in global rom. Just flash with China rom, and the key is mi flash 2018 with authorized mi account which we posted in miui Russia forum to get authorized for bricked arp redmi note 5 pro

I bought this bricked phone from someone, XE model, he flashed to global rom and forgot to choose Clear All, he check Clear and Lock in Mi Flash,
Then the phone is bootloop for a month, he tried to flash, etc with any methods, flash recovery, etc
That's how his phone system destroyed
Sorry for my bad english
If your system says it got destroyed it isn't destroyed it only locked the bootloader and that means you have to unlock it again to access the rom.
@jhs39 and ryan mixed: You´re absolutely right: Due to a failed flash to Android P, my Mix2s got hardbricked -
only showing 'The system is destroyed' - the bootloader was re-locked - only Fastboot was working.
I was able to re-unlock the bootloader by using the latest MiUnlockTool ( the older ones got stuck at 50%... )
- after that, the phone was booting again and everything was OK. My experience is: forget all workarounds with
deepflash cables, testpoint aso - the possibility to damage the hardware of the phone is excessive and they won´t
lead to success. The only way to get it working again is to unlock the bootloader! And this is working not depending
if usb debugging is enabled or you got ´find my phone´ enabled in your mi.account,....

Hm, maybe we´re going to be a bit OT - I read the mentioned thread - who needs five mi accounts?
I have only one for my three registered Mi´s. I did the re-unlock of my Mix2s two weeks ago and
I checked it again before writing this - it still has permission. So, maybe there are other reasons why
Xiaomi has revoked some people´s accounts permission? Maybe depending on the age of the
account, the region, or they reglement the number? IDK. Only Xiaomi knows...

For backup, cause of hardbrick of redmi note 5 anti rollback, no fastboot, no recovery, etc, the only way is to flash in edl for ubl devices, otherwise for non ubl devices we do test point, not permission to unlock, but permission to flash in edl mode.
Try miflash 2018,go to "mi" folder, login with your account, see unauthorized or authorized.
OK, arb can be a bad trap for owners of redmi note 5, but is it also
applicable to the Mix2s? As I wrote, I used the 'old' miflash_unlock
( ver. 3.3.525.23 ) and after that I flashed from failed Android P to
global dev. and then again to Android P using XiaoMiFlash
( ver. 2017.4.25.0 ). And honestly, I´m a bit scared of trying a new
tool...

I mean the flashing method, not about ARB.
I used that method for my bricked mi mix 2s,
XE model with Locked BL in global rom,
Just fastboot and recovery,
Bootloop,
Everytime i flash with MI PC Suite 3.0 beta, it's detected as Global or XA model, when i flashed, phone bricked again.
I do try unlock BL again, and got message "this account is not bound to device or something like that" in Mi Unlock
So i downloaded MiFlash 2018 + borrow authorized mi account,
Do test point by opening rear side,
Then flashed China Stable or Developer Rom & my phone is up again
I guess your phone is XA, not XE
Sorry, but @Pfofeldix is right. I have the XE model and once I locked the bootloader while being on Global ROM. Phone went softbricked of course, but I used Mi Unlock to unlock it and it went back to life again. Then I've done the whole procedure multiple times and during every single one of them I was able to "revive" my phone.
There's no point in destroying the phone when you can achieve the same outcome with the phone intact, left alone that some people say that the testpoint method doesn't work.
I don't know why some people can't relock and unlock again, but it definitely is possible if you did everything right in the first place.

Because you can unlock it before, when it unlocked, of course you can flash to any rom.
The problem was my phone Locked in hardbrick state,
Mi account not bound to device.
that's why i do test point, i didn't suggest people to destroy their phone, i do for my phone and it back to life. It's ok, i just want to share.

That's a different situation. The person who posted that had 5 accounts. I've used the same MI Account to unlock the bootloader on all 4 of the Xiaomi devices that I've owned. If you got caught using multiple accounts to request bootloader unlock I think Xiaomi always deauthorized the accounts.

Hi guys,
Just got the Poco F2 Pro, the device feels and looks great, but coming from an OnePlus 6T I've been trying to read a bit more about the Xiaomi unlocking & flashing tricks, as it's a little bit more complicated (and it looks like I got time, since the MI unlock tool will take 168h to let me unlock my bootloader) but there isn't much movement here in XDA so far. What are the ways to hard brick and what should I double check before flashing stuff?
I've seen some people reporting bootloop after flashing TWRP, both 3.4.1B and 3.4.2B, but it looks kinda random and I assumed it can be fixed through fastboot or MI flash tool.
I'm on global MIUI 12 (12.0.1.0.QJKMIXM). Can the Xiaomi.eu ROM be installed on any variant? Are there regional locks when trying to flash ROMs with different bases through TWRP or MI flash tool?
Does it use A/B or regular partitioning?
From what I understand, the only way to actually hard brick (which is a dead end for me, because there is no support here in Brazil) is to relock the bootloader and mess something up. I read that it's possible (and looks like the default behavior) to relock the bootloader through the MI flash tool. Is there any other way to relock the bootloader that I should be careful with? Can it happen accidentally through TWRP or when updating somehow?
Thank you very much!

With Locked bootloader? Certainly not. Unlocking and then re-locking again is not difficult/will not break warranty, downgrading however does break Warranty if they found out.
If you decide to go with unlock/relock process, All you need to start is to look here: Poco X3/NFC index.
Before you begin though, first Connect your phone in fastboot mode and use:
Code:
fastboot getvar anti
to check Anti Rollback counter. The output should be 2.
If it is less than 2, then unfortunately you cannot downgrade to Official MIUI A10 safely. (There
are methods, but they cost money and/or carry a high risk of bricking)
My advice is to unlock your bootloader and flash a Custom ROM. MIUI A11 is not made for the Snapdragon 732G Chipset that comes with your device, it is full of bloatware and stuters at every corner. In comparison to the custom ROMs here on xda, which are very smooth last and longer in battery life. Most important of all, a lot of them pass Safetynet/are google play certified out-of-the-box.

had the same problem. Flashed MIUI 12 EU instead. problems solved/
Yes you can via advanced update on the phone you just have to rename the update, there's a tutorial hit me up if you're interested..
Please help me out with the tutorial where i can downgrade my poco x3 nfc to miui eu
Hello guys, This is my first thread on XDA forum.
I just bought Xiaomi device (Poco X3 Pro Global) a few days ago.
So this is my first time to try custom rom, I searched what I'm trying to do, I'd like to make sure whether what I understand is correct or not since I'm totally new on custom rom.
the sources I mainly referred to:
source1
source2
Basic assumption:
1. Only flash custom rom without rooting
2. All unlocking bootloader and flashing custom rom process done perfectly, and all resouces (recovery, rom, ADB tool etc...) used during process are 100% clean and genuine.
3. No cold boot attack (source2) happens on me.
Q1. source1 is really helpful, but it's from 2012, is this still valid today?
Q2. source1 is posted on Galaxy Nexus forum, but is this applied to all android based devices, right?
Q3. This threat model assumes attacker has physical access to device, then I guess unlocking bootloader itself is 100% totally irrelevant to software level security risks like malware or OS vulnerability, is this right? (assuming no rooting and 100% genuine rom and resources)
Q4. From source1 you can choose between [device encryption] and [relocking bootloader] to protect security, which methods do you recommend using?
I feel I'm much more inclined to try device encryption method since I don't know if it's possible to relock bootloader safely after migrating from Global stock rom to xiaomi.eu rom. (Can anyone confirm this?) I fear it become bricked during relocking process.
Q5. So if I set device encryption with strong password and turn off USB debugging mode, I need not too worrysome?
Are there any other points in terms of security to bear in mind if you use device with unlocked bootloader?
Thank you for reading my thread

that's what I linked in thread (source1)
Only a side-remark:
An Android Smartphone bootloader is processor-specific and every OEM has its own version of bootloader specific for the hardware present in its environment.
It's the primary task of every bootloader to verify the Android OS to be loaded is genuine means signed by OEM to ensure the Android OS ( it's by nature a Custom ROM ) works flawlessly as it can be expected by user. People who use a phone as a tool and not as a toy probably never come up with the idea to unlock the bootloader because they know about the strengths and weaknesses of the phone when they bought it, they can expect that OEM did their best with regards to a phone's performance - OEMs are certainly not dumber than generally claimed by the modder / hacker scene.
My POV: Unlocking a phone's bootloader is an unnecessary action at all. If people do so they indirectly admit that they have purchased a phone that does not meet their expectations - they have made a wrong purchase.
Thanks for comment.
I understand your POV.
I realized later Global rom can't do call recording, that's the main reason why I try to flash xiaomi.eu rom and other optimazations are second reason.
And this phone will be my main phone so I wanted to make sure about security risk before I will change rom.

Having an unlocked bootloader doesn't need to be a risk whatsover as long as you're not flashing untrusted ROMS and other components to the device and critically control anything being flashed to the device. If you're flashing a signed ROM from the manufacturer as it sounds like is your plan, there is nothing to worry about. You can even lock the BL again after flashing & optimizing if you absolutely wish to although usually not recommended.
Incorrect battery report, device heating up even in general use (not gaming), and due to heating, i had to use fan and/or phone cooler just to get fast charging working, since fast charging is disabled if phone gets too hot. Is anybody else having this issues after updating to MIUI global 2.5.5? I just got this phone for about 3 months now and my device is still vanilla, never unlocked bootloader.

I'd like to avoid any problem as much as possible. So without any confirmation if that method is safe, I'll just gonna look for other method that is safe guarantee.
Android modding is too complicated nowadays I won't even bother to unlock bootloader. This is the first device that I haven't rooted within a week after buying it.

When downgrading, the most issue is regarding the ARB index of MIUI ROM and Anti version of your phone.
There's explanation in step 11 here: https://forum.xda-developers.com/t/4288121/post-85137963
Downgrading without unlock bootloader you can read here: https://forum.xda-developers.com/t/4356497/

Even official Xiaomi/Redmi/Poco cannot guarantee you their phone will not brick with normal use, so they give the warranty period.
