rom booting problem
hello guys i have a xiaomi mi 6. I got it from china and wanted to change to a global rom. I started all the proccess and when I tryied to select the rom i pressed the global stable one and it started downloading and installing the global developer rom. When it finished installing I started the device and when i selected the language the phone started rebooting and didnt stop doing that. then I trying to put an other rom to the phone and it didnt let me because i didnt have usb debugging enabled and i couldnt enable it because the device wasnt able to open further than the lock screen. I tryed unlocking the bootloader but me account wasnt linked with the device any more so it wasnt possible. I somebody help please. I am not able to use my device.

Ah but to change from China to global ROM or the other way requires unlocked boot loader...
Otherwise stuff like this happens.
The boot loader can be relocked again after the process.
Since the boot loader is locked there is less chance to solve the problem as you won't be able to flash twrp or use fastboot to flash firmware to the phone.
Another solution will be needed

That exactly happened to me.
I unbricked my phone with testpoint method.
It's easy procedure but you will have to open up your phone..
I Did it and never opened a phone before, its about open it and link 2 dots with a wire or something, and Then it goes to download mode and allows you to use mi flash and flash mi6. I recommend chinese developer rom (it will allow you to unlock bootloader afterwards)
Watch this russian guy do it, he makes it easy it took hours for me just search "mi6 testpoint" on YouTube

I got it fixed thank you guys

Using the special cable to flash successfully with miflash but stuck on mi logo

I've got a mi 5s plus with a locked bootloader and i read that you can use the special cable and the qualcomm mode to flash a rom with miflash.
I've tried the global stable and china stable with both saying success in miflash. but when i go to start the phone it doesnt start on the first press. then on the second its stuck on the mi logo.
i think im able to get to fastboot/recovery mode but as my bootloader is locked i dont think that matters.
How are people flashing with miflash with a locked bootloader. I've tried so many times with the same outcome.
any help would be appreciated.
Anyone? The phone just seems stuck in EDL mode...... ive successfully flashed it over 15 times now but it wont start up.

I'm not aware of any special cables, the first thing is to unlock your bootloader, you can use this process (http://forum.xda-developers.com/mi-5/how-to/unlocking-xiaomi-mi-5-bootloader-t3336243)
After that you can install any rom

Thanks I suppose this is the way I might have to do it. Is there a way to lock the bootloader after flashing so that Android Pay and my work apps still work?

Mi5s Plus bootloader unlock problem

Wondering if anyone is able to help me.
Recently purchased a MI5S Plus and having problems unlocking the bootloader. Followed all instructions and the unlock fails at 50% with the tool stating that "the account on the device is different than current account" (or something like that).
Now here's what I have done so far:
-made sure device and tool are using the same account with phone number login
-made sure "find device" is turned on and phone can be found
-disabled windows 10 driver signature
-enabled usb debugging on the device
-made sure sim card is in slot 1 of device
So far no dice. Phone is on Global Stable (8.0.1.0) but I wanted to move to EU version (which also has the correct UK locale and some other features). I am not new to the rom flashing scene (just moved from iOS to android and had a Galaxy S2 back in the day).
If anyone could help me with this it would be greatly appreciated. No idea what else to try.
Best regards

I think what this means is that your phone is associated to a mi account different than the one you have logged in to unlock it. Make sure your phone has the same mi account as the one you are using to unlock it.
Good luck!!

Yes it's the same account in both places. I double checked that.

Hi, I will share some of my experience.
Myself had that problem too, bought mi5s plus on global 8.x.x and wanted to move to eu version . The problem with this phone is that there's no global dev rom for it just yet, and you can't officially flash the china dev rom, since the installer doesn't recognize the package. So you find yourself in kind of loop, like
==> to open bootloader you need dev rom (only china available) :/
==> to flash china dev rom via mi flash you need to get your phone to EDM ( Emergency Download Mode ) .
But to get to EDM you need open bootloader.
That's kinda sucks, but i kept looking over the internet and found the overall solution that will probably work on any xiaomi device. And that's to make "Deep flash cable". This cable let's you enter EDM ignoring the locked bootloader, this way you can flash the china dev rom, and from there open the bootloader.
The idea is really simple, just need to shortcut any of the middle connectors of the usb with the ground(the outter connector) when plugging the phone into the pc(don't even need to cut the original usb cable), that will prevent the phone from starting to charge and it will enter EDM (pure black screen without any sign of life, but pc will recognize it on COM port as long as you have qualcomm drivers installed.) In this mode the mi flash tool will recognize the phone and you can flash the china dev rom.
If you need more help just ask, and u can find some nice guides on youtube that explain how to make the cable. Good luck!

Thanks makslll, I have mi5s, wondering if the process is different?
I bought my phone with the xiaomi.eu rom (8.0.10.0 MAGCNDH), unlocked bootloader with "MiFlashUnlock_1.1.0317.1_en" and installed recovery following this (https://xiaomi.eu/community/threads/6-12-1.36462/). After this I was able to install other ROMs .
Hope this helps

Main problem I'm getting at the moment is the fact I can't get past the 50% on the unlock process. Keeps giving me an account error on the Mi Flash unlock tool. Something like "Account on the device is different from current account".
In any case I was looking at this EDL solution but let me see if I grasped this:
-I can use EDL to bypass locked bootloader restrictions. Could I just flash the EU rom without unlocking the bootloader?
-That not being the case, I'm guessing I would need to flash something like China Dev and the try and unlock the bootloader followed by TWRP flash, etc etc.
If someone could shed any light on this that would be great.
Thanks in advance

Thanks will give this a bash later on after first trying to factory reset the phone.
Thing is I read about a lot of people being successful unlocking their bootloader on Global Stable rom, so no idea why I can't do it. Pretty sure I have all the necessary drivers and I'm following the process as it should. Still getting the account error.
Xiaomi should sort their **** out...
Thanks everyone for your help!

You can't flash Eu ROM with locked bootloader, since you need to use special image files of the supported roms for miflash (Can't use the .zip roms that we flash via recovery), and those available only for the official roms ( global stable, china stable, china dev).
So yeah, unfortunally this would take little longer, but i can assure you this method 100% works and it's not very hard once you've done the tricky thing with the deep flash cable =)

On another note, if a Global Dev rom is released for the Mi5S Plus, are you able to flash it as normal through the updater app?

Yes, on my gf's mi5 i just flashed global dev rom from the updater and unlocked it easy, they really should just remove the global <==> china barrier
Update: there is official Global Dev ROM available now, so no "deep flash cable" is needed anymore, just download the ROM, copy it to phone memory, and flash it via updater, good luck =)
So, quick update.
Managed to unlock bootloader last night by updating to the new Global Dev for the Mi5S Plus.
However a new problem has arisen, as usual. Using ADB, it recognises the phone whilst in normal mode with USB debugging on. The moment I reboot it into fastboot mode (to flash TWRP), it doesn't recognise it anymore. The drivers are installed as I disabled windows driver signature verification, but the phone is just not recognised anymore.
Anyone have any idea how to fix this?
Thanks in advance.

Locked bootloader, stuck in recovery mode.

Hello guys.
I recently bought this phone and wanted to use netflix, but didn't allow me because it outdated and said it was not compatible with my phone. So I did a bit of research and found a post in "mi community" that said it was because phone had bootloader unlocked. The phone was new and I didn't change anything of it, but I found the bootloader was unlocked.
Installed fastboot and adb drivers, locked bootloader and got myself into a... Brick?
-I can still load into fastboot.
-If I turn on the phone, It tries to load android but loads Mi-Recovery 3.0 instead. Recovery also says "This MIUI version can't be installed on this device"
I'm so lost from this point, I need to know if there is a way to flash any rom, and which one do I need.
Thanks in advice
stuck on recovery
Most likely a chinese phone that came with global rom. If it came with global rom try flashing chinese rom and then unlocking bootloader and reflash global. Do not lock bootloader after flashing global.

Thanks for your answer, that is exactly what I've.
The problem is I tried to flash a Chinese from but it always denie it. Tried to flash the last global rom and allows me to do it with the same program.
Not sure where I can get the official chinese rom or how to bypass the xiaomi protection.
Thanks for helping! Hope I can somehow do it
Locked bootloader
Try searching for tools below which might help.

XiaomiADBFastbootTools-6.5.1-Win
I had hard bricked mine and had to take back off and use EDL to revive.

If you can flash global ROM. I think you just need to unlock bootloader and then flash China ROM once you have unlocked bootloader.

It lets me flash de global one, but when I try to do the same with chinese rom, it says the version is lower, so I can't "downgrade".
It's weird because according to version number, the global one was a few versions lower
Solved the issue
The same issue , i was also encountered , After Flashing with "Xiaomi_Mi_Max_3_V10.2.1.0.PEDMIXM_20190226.0000.00_Global_9.0" Mi Max 3 with the MiFlash20191206 tool , by default the tool used "Clear data and Lock".
The tool saying "Flashing" and my phone got rebooted and went to MI Recovery 3.0 and also i got the message as
"This MIUI version can't be installed on this device".
I am not clueless how to proceed. So downloaded the Chinese version and again i tried to flash with above tool. Now tool said that "Can't Erase Locked" phone.
So Now i connected to Miflash_unlock with fastboot and connected to mi account and again i unlocked the phone.
Now my phone automatically booted to the Global version.
So i hope the issue is selecting the option as "Clear data and lock" . We need to select only "Clear data" in the flash tool.

Hi there,
I encountered the same issue. I tried to flash some CN Rom without enough research, without knowing that you can't just flash an Android 10 rom from 9 directly by recovery (even TWRP). So I ended up Fastboot or TWRP but never able to boot into system. Fortunately I didn't flash my Max3 by fastboot rushly, so my phone was still unlocked.
This is how I solved it:
1. Download an official CN ROM (the below I used is MIUI 11 with Android 9.9.x);
I can't post link here but search "miui通过线刷升级" - you shall see a miui.com link ending with shuaji-393.html. That's the page I download the Mi Max3 ROM from.
2. Use MiFlash to flash the official ROM with the flash option "clean all", NOT "clean All and lock";
3. The phone shall reboot into system, give it 5-10 minutes;
4. Flash the miui.eu ROM you like (DO make sure it is Android 9 tho) by recovery (tutorial given under every official xiaomi.eu ROM download).
Again it's easy to search
It took me less than an hour to do it (I don't have much experience with new XiaoMi phone). So don't worry about bricking your phone forever.
Hope it helps to destress
Hi guys. I need some help too because I'm not totally sure what I have to do here so if anyone can give me some tips I would appreciate it.
I just ordered the 128gb 6gb ram version of Mi Max 3 and it might come with the global rom and already unlocked. Should I use the Mi flash tool to install the file MIUI 11 V11.0.3.0.PEDCNXM android 9 fastboot file? then after that installs I should lock the bootloader and then unlock it again myself with my mi own account? I just want to make sure that this is the correct way to do it.
Also after it I unlock it should I flash the newest xiaomi.eu rom with android 10 or do i have to do something else first? Thank you

i have the same issue of not able to get into recovery but able to go into fastboot while trying to boot normally just gets stuck at logo phone is able to charge. Showed to a local repair shop who says its a power ic issue searched web where someone mentioned about issue w flash memory (this was for some samsung phone not sure if it applies to mi). I have no clue does anyone know how i can eliminate some of my doubs step by step?
1. I think it may be my power/volume button strip but i dont know how can i test thee device without the strip (i have some schematics) .
2. Maybe Rom issue and since bootloader is locked and no usb debugging enabled nor i can unlock it using official tool since it requires me to go to developer settings and link my mi account i cant flash anything (though i came across some posts claiming you can bypass edl authorization using 2017-18 flash tools and anti5 test i dont have a clue as to what to do).
3. due to recent conflicts i cannot access mi india forums and nor can download proper official stock rom( since its my relatives phone i dont know what version it was on )
4. the phone was dropped previously which cracked the glass but was in working condition for more than 3-4 months atleast .Cant find any trace of water damage inside.
5. got some schematics from web by searching here and there but i dont know how to troubleshoot lol.
Any help would be appreciated , i cannot trust local technicians as there have been past incidences of missing parts from device after they keep for a day and return next day(skeptical if there are some parts missing or replaced w defective ones ).
Will update if i get it working.

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot
Did Mi Flash give an error message after trying to flash?

I dont recall giving an error, so i dont think so
now it is though, when trying to flash the firmware. error erasing boot_ab (failed: erase not allowed in lock state)

I'm not sure, but you may still be able to flash official ROMs.
But in "Configuration" make sure Erase is disabled

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

this doesn't seem to be an option. there is a checkbox with "erase all" but all are already unchecked

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!
If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

That's what I'm thinking too ...
Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

thanks everyone for all the replies!
tried unlocking it via the mi unlock tool (latest) but it says (in chinese) its locked by nr 123***456 by searching the phone - can't unlock
edit:
google lens translates:
X The phone has been locked by the account number 661****647 by searching the phone, Can't unlock
but it's not the nr. of my account..

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I also tried to simulate a local OTA by copying update.zip to internal storage using ADB push command and booting into recovery mode to flash ... But it doesn't work for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting
I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

[Solved] Stuck in fastboot with locked bootloader

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.
