Hi everyone, some weeks ago I converted my A2 in 6X because I wanted to test MIUI. Yesterday, dealing with an update my phone get into a bootloop. Well, I used MiFlash to fix it but I selected "flash and lock" (yes, I know, I'm stupid).
The main thing is that I'm in a Chinese ROM with lock bootloader and when I try to unlock it I get error 86023.
I dont know what to do. I've thought about test point to flash Xiaomi.eu but I'm not sure bcause the bootloader is locked.
Someone with a posibble solution? Thanks
Welcome to the Club
Same thing happened to me.
You can now choose between China Developer or Stable.
I tried many progs and tutorials to unlock the bootloader but no way.
If you need GooglePlayStore, CalenderSync and ContactsSync:

I'm now on stable V10.3.6.0.PDCCNXM and all is working quite well.

It didn't happened to me for myself, but I just asked this question to get better knowledge about bootloader stuffs:
As I understood the current problem is this:
You need to unlock your bootloader again, there is just (as much as I know) 2 ways to approach, which both of them will not help you:
1. Unlocking as a A2 : but your device is not a A2 anymore, so the device will not be unlocked by this method.
2. Unlocking as a 6x : but this one won't be successful either since the dedicated unlocking program asks for a real 6X device with a registered IMEI number by factory, which in your case is NOT.
So, you will be left just with the options that need no Unlocked Bootloader, as mentioned above, like Chinese Stable versions. ( That in my opinion it does NOT sound awful. )
(BTW, every day comes with new procedures, maybe you can find a new method to unlocked the bootloader again, there was times that many expertise told, after stucking in ARB4 trap, you just need to find a suitable Trash for your device!, but now we all know that there is plenty new ways to deal with it).

not the imei, it asks for 6x serial number which device is a2. you have to find someone who has authorized mi account to unlock this device. it is only way for now

Authorized Customer Services, or a friend who works there
It is very possible that they can restore your phone (and as well your bootloader) as what it was in factory.

Yes, exactly.
Hello my friends, i managed to unlock the bootloader of my converted A2/6X.
I tried several times to switch from stable china to developer china but from 9.8.15 to 9.9.3 no one worked.
After installing one of the developer roms, the phone only shows the boot screen for 2 seconds and turns off, with charger it boots endlessly or shows the green battery symbol after some minutes.
One thing that works, is using a rubber band to fix "Vol+" and connect phone via usb or charger, mostly after 5-10 minutes it will enter the "Miui-Recovery", then you can start "Mi-Assistent" in the "Miui-Recovery" and flash back the stable china, so luckily no need of EDL.
After flashing the last 9.9.3 rom and the phone was all screwed up, again. I tried the original "miflash_unlock-en-2.2.624.14" and it worked.
I have done this "thousand" times before with all available unlock tools I found but never succeeded before.
Download: miflash_unlock-en-2.2.624.14
https://xiaomifirmware.com/downloads/download-mi-unlock-2-2-624-14-windows/
https://androidfilehost.com/?fid=889764386195916630
Now I tried to boot into recovery “fastboot boot twrp_wayne.img” but it didn't work, because the phone reboots or turns off after 2 seconds.
So I flashed the china stable via fastboot (worked), let it boot up, no setup, reboot to enter fastboot and flashed successful the orangefox-twrp.
Hope somebody can also unlock his bootloader or maybe it was just luck.

Amazing Dude. [emoji108][emoji108][emoji108][emoji108][emoji108] Congratulations.
So I installed a custom rom in my new k20 pro lately, and accidentally locked the device after installed the custom rom inside. Now, my device is refusing to open the new rom and stuck in redmi recovery mode. It said that "this MIUI version cant be installed on this device". I tried to unlock the phone again, but xiaomi said that it takes at least 30 days to unlock a new device. Im kinda sad and confused about this, please help.
How did you lock the bootloader with custom ROM installed?

Did you try to flash custom rom using miflash?
Hi! I have the same issue on my Xiaomi Mi 11 Pro (It was Chinese) but it came unlocked with xiaomi.eu rom.
After i installed a global rom, and google wallet nfc pay did not work, so i thought okay i will lock it then so maybe wallet would accept it, (with the eu rom it worked before) so i put the device in fastboot and used fastboot oem lock on cmd...
And from then it stucks on miui recovery 5.0 screen, and says, this miui version can't be installed on this device...
I might not enabled oem unlocking before i shut if off, but i added it to my mi account so i dont know if after a week i can maybe unlock it. But i think the other possible solution would be to sideload the original chinese stock rom, which is for M2102K1AC, Mi 11 pro, codename mars, but i couldn't find it anywhere... If someone can upload a link to it, that would be a huge help! Or any idea! thx!
geraldmany said:
HI! i got a mi 11 pro 1 year ago, and it was offically chinese, but it came unlocked with Xiaomi.eu firmware, but i could't update it via the updater app, so i searched and found the global star version and just flashed it, everything worked, only now google pay nfc didnt work, it said that its probably because of the unlocked bootloader, so i got to fastboot and in cmd i sent fastboot oem lock, and since then my phone is stuck in miui recovery 5.0 screen and says that i cannot run this firmware on the device, i tried to unlock it but failed, maybe after a week, but i think that i didnt turn on oem unlocking on the phone itself before this... So im just hoping that after a week unlocking could be done... Or my other idea is, that i could install the original chinese rom with sideload, because i managed to install another global version on it since, but the result is still the same, the only problem is that i cannot find literally anywhere a mars codenamed firmware...

Anyone who might have the same situation, i found a simple, but effective solution, not sure if it works on every xiaomi device, but i will write down the steps here:
You need to use XiaomiADB, here is the download link and the description for how to use it -> https://xiaomiui.net/how-to-use-xiaomiadb-8044/ (if the page is not available, then feel free to msg me!)
For xiaomi adb, you need to go to 3rd option on the miui recovery screen, NOT THE FASTBOOT
So basically i went through the steps to “xiaomiadb sideload_miui <filename>”
And I tried to install a rom, BUT IT DIDNT ACCEPT IT!
The message was:
ERROR: This rom cannot be installed, server code -> 2001, server message -> Can't install unofficial rom
after trying 4 times all the same and: Installation of this rom via stock recovery is not allowed by Xiaomi
Says Installation failed, and then i just decided to download another rom so i PLUGGED OUT THE PHONE right after this, and went to another room to connect to wired network, to download and try a different rom... when i came back, to all my surprise, the phone was turned on, so i went to the setting dev ops and enabled bootloader unlocking, linked it to my account enabled adb and everything that is needed to flash another rom later, so then i rebooted and again, miui recovery 5.0 screen, but now i enabled unlocking, so i put the phone in fastboot, and tried MI UNLOCKER TOOL again, now it says: Please unlock 168 hours later. And do not add your account in MIUI again, otherwise you will wait from scratch.
So that means, after 7 days i wll be able to unlock it, until then, i can turn it on with the above method, in short try to sideload (copy and install) a rom to it, and then after it failed, plug it out and just wait like 10-20 maybe 30 seconds and bam your device is normally booted... I hope it helps to some of you, (i have been searching for the solution for almost a week, my other option was to pay someone who can MAYBE do it or send the phone back to china and pay the repairs, so im really happy with this method! If it helps to you, please reply so i and the others will know that it worked! Have a nice day!
Hi, so I bought Mi11 CN version around 2 months ago I flashed stock EU rom via Fast boot and was working fine, but randomly rotation would stop working usually restart would get it working but stop working after 1-2 days and recently totally stopped working I tried all the CIT tests and no response , Today I flashed latest Xiaomi.EU stable rom and still the same issue , is it hardware fault or anything else I can do I searched and with older models people flashed fixes ? wondering if can find the same ?
Thanks

Try to flash a full rom with this tool.
Rom
Dont relock bootloader.
"I did this when I first got the phone and flashed stock EU rom, Will do it again if no one else responds with any other methods, and I really need to use phone and hassle each time to set everything up after reflashing"
There are 3 methods, Miflash is the safest to avoid problems afterwards.
Reflash the original rom (cn) and test.
Ok thanks, as I dont have backup phone its a lot of hassle testing etc and I need my phone most of the time

How to go back if the fastboot mode no longer works?
got it working again, paid for service which I think uses EDL to recover he flashed CN rom still rotation not working so I really think its hardware fault
before I return can i relock the bootloader ? phone is originally CN and flashed back CN ROM just boot loader is unlocked
@NOSS8 that profile GIF sums me up right now
Hi Guys,
i am experiencing random freezes and weird restarts for about 4 weeks now. Sometimes the MI Logo shows not in the middle but on random locations on the screen and it is not necessary to do the pin input. Did anyone have the same experience? This is the Reason to try and unlock the bootloader.
Greetings

And you have?
Rooted?
Bootloader unlocked?
Bone stock?
Magisk?
Aosp?
Xiaomi eu? Beta? Stable?
While its not nice that you have experienced some issues the technology is no there yet...we cant read minds or/and predict outcome
Please provide us with something we can work on and i am sure we will do our best.... But standard advice would be factory reset as nr1.
Take care and best of luck

I have almost the same symptoms with Mi11 global version Miui 12.5 locked bootloader , the phone freezes and the screen flickers, but no problem appears on the bootloader or the recovery, the strangest thing is that when I use the PUBG mobile games everything works normal, I tried several ROMs but the problem persists

Sure... Locked bootloader...tried several roms....i lost it ..
i tried everything, i still have tried edl flash method, but i don't have an authorized xiaomi account
Soo, long story short, i hard bricked this phone and i definitely need good advice. Please bear with me:
I got a Poco M5s,
I wanted to install official PE on it.
I successfully unlocked bootloader (mtk client method)
I ****ed up because i flashed the recovery, but it was for the wrong MIUI version (i had A13 - SFFEUXM and PE needs A12 - RKLMIXM)
Then i compounded my mistake because i booted to fastboot over linux and flashed A12 - RKLMIXM (flashall.sh). The phone never booted after that.
Now the phone is fully unresponsive: Black screen and power/volume buttons seem to do nothing.
I tried to use SP Flash to reflash A13 - SFFEUXM, but it failed and wanted me to remove battery and retry.
I tried to disassemble the phone, specifically removing/reattaching the battery plug: no change in response & SP flash did not seem to download anything
I also tried to see if mtk client can detect the device, but worryingly, it thinks it is a Helio G90 (MT6785) instead of G95, and then fails with "DAXFlash - [LIB]: Error on sending emi: unpack requires a buffer of 12 bytes"
I'm totally disappointed at this point. Is this salvageable? What can i do?

I have tried to rollback to 12.5 too. Got a bootloop. So I searched online about it and found out that you need to use the latest Mi Flash tool ( I used 2020 version ). Then I tried with the 2022 version but this time I was getting a timeout error. The flash was stopping at 700 seconds. Since I have a really old and slow PC, it takes about 1200 seconds to flash. After that I have given up.
Which version of Mi Flash tool did you try? Try with the latest version if you have a relatively fast PC.

I've tried various miflash versions (2017,2018,2020,2022). It always times out.
On linux, i managed to complete a flash using "flash_all.sh", but that's how i bricked it.
Hello, don't know if it is the good place for this but I have done the latest update (I have a Poco M5s with the version 13.0.10.0) and I just found the recovery flash for it (same version, Global.). I managed to unlock the phone after a few weeks of the phone being unrecognized by the pc, no matter how hard I tried to get the updated adb and android drivers. The latest Windows update included the Android drivers (which enabled me to unlock the bootloader).
I am planning to flash it using Magisk, any advice or things I should know?
