On Saturday appeared an OTA update to do on my mi A2 but after installed and restarting it died. It does not enter recovery mode and the screen is always on with android one bootscreen logo.
PS: I never flash the phone and i never change anyting in the system of the phone.
The only response that i have in the phone is enter in it Fastboot menu. I read some threads and untill now i cant fix my phone.
I will try to explain what i do:
I've tried using this tool https://forum.xda-developers.com/mi-a2/how-to/mi-a2-toolkit-unlock-bootloader-root-t3834585.
I try option 3 (Unbrick/Revert to Stock/Force update and the program tell me to unlock the bootloader.
When i tried to unlock bootloader by option 1 and then 1, 2 and 3 ( Unlock flashing critical, unlock OEM , unlock flashing ) the programs says: Failed Unlock is not allowed.
Then i try the response 9 to this thread https://forum.xda-developers.com/mi-a2/help/impossible-flashing-xiaomi-mi-a2-t3837565 to try unlocked the bootloader
But i have the same response ( Flashing Unlock is not allowed )
I read and i try but i cant unbrick my phone, someone can help?? Thanks
We are in the same boat buddy, the same thing happened to the phone of my wife.
It *sounds* like the update failed, and normally that would mean it would switch the slot back to the one that was working and boot that.
But you've tried a bunch of options from some tool, I've no idea what it did, as the tool doesn't tell you what commands it's doing.
I'd suggest to go to fastboot and see if you can tell which slot is active, then switch it to the other slot, then do fastboot reboot and cross your fingers
I have the same problem (for other reasons, but exactly the same problem). You can also try "fastboot oem edl", but it did not work for me, so I suppose you have little chance for it to work.
I have been searching and it looks like there are some "deep flash cables" that can make the phone enter edl mode to flash it using mi flash tool. Maybe these could work for us. There is apparently other way to enter edl mode, but it requires opening the phone (that I do not want to do) to short two test points.
I cant enter revorymode only fastboot mode. But when in fastbootmode my connected pc cant even find the phone. Im going to return the phone.
I have the same problem, I have this edl cable but so far no luck.
Do not realy k Ow how to use.
Are you sure it was the OTA update that bricked your phone? That Treble system isn't just there for the kicks, its there to prevent serious issues like these.
I'm stucked on fastboot, I don't want to open my phone. Could anyone help us? I already tried a lot of things, my computer doesn't recognize my mobile when is on fastboot mode. I already tried to install a lot of drivers or try to use differents adbs.
Hello all!
I recently bought a second hand Xiaomi MI A2 online however I found a problem.
The previous owner did a factory reset on it but I'm stuck in the initial set up configuration because it asks me for the google account credentials attached to the phone. I texted the previous owner but had no answer.
So I tried to flash the official ROM to bypass the issue but I get an error message from Xiaomi Flash Tool saying "remote: Flash is not allowed in Lock State".
I think this is happening for one of the following reasons:
The previous owner didn't enable USB Debugging (thing I can't do because I'm stuck in the set up configuration)
The bootloader is locked (and I can't unlock it because I don't have the credentials of the attached account)
Does anyone knows how can I solve this problem?
Thank you for your attention

Thanks. I've tried the MIFlash Tool and I get Error Flashing Not allowed in Lock State. I've also tried the MI A2 ToolKit and get the same message. Basically anything I try and do states device is locked or unable to run in Lock State.
Boot Loader is currently locked and I cannot access developer mode to enable OEM unlocking. Question I have is :
- Can I use EDL Cable to work around this or do EDL cables not longer work with Newer Xiaomi phones?
- If EDL cable doesn't work, is the tespoint method my only option.
thanks in advance

yes it's difficult .... I understand
edl maybe work, but I'm not sure...maybe if you go to a repair shop is a better solution

I would try a wipe from the recovery but if that doesnt work then just test point the phone. It isnt that hard, I had to do it myself today because of a soft brick. You just need a T3 screwdriver really. Take out the 2 bottom screws. Take a razor and slide it under the corner of the display and lift it enough the get a credit card in there. Then just work around and you should be able to get the screen off. Take the small metal plate off just above the battery and disconnect the battery and the connector on the right. There will be the test points, short them out, connect the phone to the pc(you can stop shorting out the points when it gets detected) and you have like 10-15secs to start flashing the phone in miflash(obviously you need to have the drivers already set up).
I have same problem with xiaomi mi a2 which had bootloop. Was not able to start device at all so no oem unloco no developer options and no usb debug. It was possible only adb sideload and fastboot. Adb sideload did nothing. I was trying to flash with adb sideload but it stops at 47% with message 1.00 x. Did try several roms with same results. Then i tried fastboot options. Falied to unlock not allowed. Itsl was impossible to get even into phone to activate developer options so i can activate oem unlock and the rest. I tried edl mode which did flash but then i got error message in bootloader it failed to mount system etc. Then i tried mi x6 rom to convert phone to another which doesnt have usual recovery mode but a stripped oem recovery mode. Now when u go back to mi a2 rom its bricked so there is no option of adb at all now. I tried to use mi x6 mi assistant option but app wont recognize usb connection it shows try normal mode then switch. When activating mi assistant on phone it does recognize rom version from recovefy flash in mi assistant app but when it downloads update rom version it cant continue. With pixel you can do anything with adb and it is so easy but xiaomi sucks big time. You cant do anything. Fastboot flashing unlock critical and fastboot oem unlock gets error failed. Flashing not allowed. U tried diferent cables but no luck. So now what? Thats why i hate adb. On samsung odin you can do impossible possible. Even with sp tools on mtk. Even boxes works flawlessly but xiaomi system is just thr worse. It doesnt matter if you get soemthing lost there is always a solution to other phones.
After having device sit as a paper weight for a few months, i broke down and ordered a phone repair kit. Opened device up and flashed via test point method. Worked Flawless. Time to enable OEM unlock so i don't have to open it up again. Thanks to community for all the help.
Use cmd
- go to fastboot then "fastboot oem unlock"
- go to fastboot again "fastboot flashing unlock_critical"
Flash with mi flash
Done
Just stumbled upon this and while may be 18 months too late, here's the step by step process to flash ROM on MI A2 that's giving error "Flash is not allowed in Lock State":
1) switch off device
2) enter fastbood mode (press hold power+vol down few seconds)
3) connect device with laptop
4) install and open adb folder on laptop (https://forum.xda-developers.com/showthread.php?t=2588979)
5) within adb folder -- shift + right click = open powershell here
6) fastboot flashing unlock_critical
7) step #6 may be pointless if phone is bricked but do it anyway
8) fastboot oem edl
9) find and download latest stock rom for your device (FASTBOOT version). It'll be .tgz file
10) extract the image folder from within (would be the same name as .tgz file)
11) open miflash (coudln't find link but look it up, it's easy)
12 select the image folder you extracted in step #10
13) click refresh. device name appear means it's recognized
14) from bottom of mi flash tool select whatever you want. I do "clean all"
15) flash (top right mi flash tool)

you need to open phone with screwdriver & do the test point ..search for video on YouTube...then EDL deepflash state you can use miflash to put back OFFICIAL only rom to device.
Here we go:
1- Today i got a new phone
2- Wanted to remove the Google search bar and disable google app
3- Restart and the phone screen is very different like another version, so i decide to do a soft reboot
4- Phone stuck on auto loop
5- Try recovery mode, dont work
6- Fastboot works
7- I download new room jasmine_global_images_V10.0.12.0.PDIMIXM_20190712.0000.00_9.0_1e580ee45b
8- Download Miflash and Minimal ADB and fastboot.
9- Plug the phone in pc
10- Unlocks OEM with app
11- Opened Mi flash
12- Miflash have installed all the drivers
13- When i click on refresh the Fastboot icon(the android and the soviet cat) dissapears and the only thing i have is in one corner "press any key to shutdown"
Important data:
-i have windows 10 with usb 3.1 and 2.0
-USB debugg is locked
-By pure luck once i managed to do a full boot sequence but when it finished the layout of the screen was different, like another version and i started updating it, after a couple of updates it stuck again on bootloop.
- i have no idea what was the original version on the room but in the last point and in nº 3 it was 10.0.7.
- i have nothing that i cannot recover so i dont mind wiping out my userdata
-i have considered a test point but i dont know if it going to work
-return it to amazon its my last ressort
- i read about the issues in december and january with the bootloop but i tried everything
-i have acces to a computer with linux
-its very difficult to start the fastboot logo/menu and almost impossible the recovery mode, it almost always ends with phone booting, when i plug it onto my pc it start with the bootloop.
-sometimes when i click on refresh while the phone with the screen in black or starting up with the android one logo it changes to fastloop automatically
- also tried a hard resset and nothing changed
I have no clue what to do, should i do the test point, ask for another in amazon, spray it with holy water??
Sorry for the possible typos and all the numbers i wanted to explain myself and to put some order in my head.
Please help and Thanks in advance

I think you should connect your phone via USB 2.0, from my previous experience, the USB 3.0 port will give press any key to shutdown message on your phone

In this case I think you haven't unlock your bootloader, or haven't unlock both OEM and critical. Following up your steps, you didn't mentioned this part.
Have you done these codes?
fastboot flashing unlock
And
fastboot flashing unlock_critical
?
Select OEM unlock in settings doesn't unlock your bootloader automatically

Hello guys, so, today i was trying to install miui 9 in my mi a2, then later going to update to miui 10. I was trying to install by flash mode (XiaoMiFlash) Everything was going fine, until my windows accidently turned off for updates (RIP). When my pc turned on, i was desperately opening miflash as fast that i could, but then when i try to install again it was saying "cannot recieve hello packet". I tried to restart it thinking that would fix it, but its just stuck in a MI logo with mi.com screen(Bootloop). I was trying to unplug usb cable and then putting again trying to fix it, clicking refresh to see if it appears, but it doesn't. Same with fastboot mode, doesn't get recognized. I really need help to fix it and sorry if i wrote something wrong, english is not my native language.
Same problem happened with me today. Any Solution?
Are you able to boot into fastboot?
Something similar happened to me once with the A2.
I somehow too managed to interrupt some update process and got stuck in the same scenario.
I could resolve it by getting one of these now superseded fastboot stock files with some installer scripts in them.
The scripts also wouldn't work, but I could install the firmware files one by one manually, following the script's content.
First off though, you could try to get into fastboot mode (as mentioned before), boot the official twrp img and flash the latest firmware zip file from here
Then you could go ahead and flash miui for the A2 like any other custom ROM (or did you just post in the wrong section and actually got an 6X? - seeing that you used miflash, it really seems like it..
Just in case here is the right thread for downloading miui for the A2: A2 miui port)

Hey, sorry for not awnsering for a long time. Yes, i can enter in fastboot, but the problem is that my MI A2 doesn't get recognized. (nothing happens if i try to flash it in fastboot mode).
i same that trouble, i can try to bootloader but when i connect usb to my pc it not recognized, i don't run anycommand from my PC,
I think if i change to second slot i will boot my phone, and i want to change slot without command "fastboot set active-slot "
Just bought a used Mi A2 from a guy. He dosent know what Android version it is and its probably locked. Ive been out of the Android game for many years now, but managed to install ADB and Fastboot on my Mac.
The problem is that the device is boot looping on the Android One logo. Managed to get into Fastboot, and the device shows up in ./fastboot devices. Tried to run this quickie, but only get a "Device is already locked!" message.
So please, point me in the right direction as both the Internet and forums here are loaded with information.
In the end I would like to have a custom ROM, LinageOS or something maybe.
Thanks in advance.

1st try to reboot numerously with external power On (if there is a valid Android One ROM in one of two slots, sooner or later bootloader is to boot into this valid ROM).
In case phone does not have a valid Android One ROM, then next step would be MiFlash'ing via EDL (search for TestPoint Guide in "Guides, ....")

Sure there is no options in fastboot mode, "enter fastboot mode and reboot" means just that -> enter fastboot mode and then reboot (either long-pressing power on phone or with "fastboot reboot" command from PC.
I gave you clues, please don't tease me to dictate step-by-step, I do not own your phone.

Most probably that's a false path, as MiFlash, Mi Account, Mi Unlock and other such stuff are for owners of "native" Xiaomi MIUI phones, while Mi A2 boarding Android One is regarded as stepchild. Better search for Android One solutions (in these forums of in developer.android.com)

Maybe. I think the phone is stock, just bricked after some update.
Just need to get the bloody torx driver!
EDIT: when I do manage to find a tiny tiny torx driver and open up the phone, disconnect the battery a bit, connect it back up, and its time to connect the two EDL pins, how long do I hold? USB cable plugged in?
Yes I have same issue, I dont understand, why Xiaomi dont do anything with this ridiculous problem, I dont login with mi account because no paid attention to that, and when I install this update the phone get in bootloop

Disclamer: Have not done it myself, but according to numerous sources the needed Steps (here with Windows PC) are:
1. Open (partially disassemble) Phone to reach 2 contact Test Point spots
2. Connect stock USB cable to USB2.x port on MB of PC, but not to phone, start Device Manager (to see that no USB-phone-related devices are connected and later to see that phone will be connected in EDL)
3. Download desired stock fastboot ROM https://forum.xda-developers.com/mi-a2/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824849 and MiFlash, start MiFlash selecting ROM
4. Span the two contacts with something metal and in this state connect USB cable to phone; Device Manager must show newly connected device detected, then contacts may be open
5. Press "Refresh" in MiFlash, same new device must be displayed
6. MiFlash -> clean all, MiFlash -> flash
7. Assemble phone back and reboot
MHO Notes:
a. when EDL/TestPoint method was forced due to soft-bricking, after unbricking it is better to: (1) fully unlock phone and (2) clean-reflash stock ROM via fasboot
(Reason: this particular specimen is subject to OTA soft -bricking)
b. if EDL/TestPoint method fails with Pie (10.0.17.0 or 10.0.2.0), retry using Oreo 9.6.17.0 or 9.6.9.0.

Xiaomi is just repacking Google's Android One updates, and, obviously, does not spend much money for testing OTAs (as AndroidOne phones are not their main market items). From the other hand, Google's Android One A/B Slots feature was developed for so called friction-less ( muhaha ) reverting to previously working ROM when updated ROM fails to boot. So, an Android One phone bootlooping after OTA MUST reboot to previous version of ROM sooner or later (supposed to be 7 retries), sure if phone is not compromised / tampered by previous user actions.

4. Span the two contacts with something metal and in this state connect USB cable to phone; Device Manager must show newly connected device detected, then contacts may be open
5. Press "Refresh" in MiFlash, same new device must be displayed
6. MiFlash -> clean all, MiFlash -> flash
7. Assemble phone back and reboot
MHO Notes:
a. when EDL/TestPoint method was forced due to soft-bricking, after unbricking it is better to: (1) fully unlock phone and (2) clean-reflash stock ROM via fasboot
(Reason: this particular specimen is subject to OTA soft -bricking)
b. if EDL/TestPoint method fails with Pie (10.0.17.0 or 10.0.2.0), retry using Oreo 9.6.17.0 or 9.6.9.0.

Xiaomi is just repacking Google's Android One updates, and, obviously, does not spend much money for testing OTAs (as AndroidOne phones are not their main market items). From the other hand, Google's Android One A/B Slots feature was developed for so called friction-less ( muhaha ) reverting to previously working ROM when updated ROM fails to boot. So, an Android One phone bootlooping after OTA MUST reboot to previous version of ROM sooner or later (supposed to be 7 retries), sure if phone is not compromised / tampered by previous user actions.

Managed to get hold of a torx set - phone is now open, battery disconncted. USB-C cable ready (dont have USB-A-C, only USB-C-C). Installed MiFlashTool on my PC and tried to get hold of the drivers. MIFlash is giving me a hard time whineing about drivers. Giving me a erorr message, something about JIT-debugging. Only got it in norwegian.
Edit: managed to flash the stock ROM I think. Fuzzed around a bit with the qualcom driver. Now I have a white screen with a rainbow passing over it..
Edit 2: and we're there! MIUI is in - now time to get rid of it!
Edit 3: think I managed to flash TWRP now - do I need root? Can I just flash a Pixelexperience ROM now or do I need to do something else? Used the Android 9 fastboot image earlier, if that has anyting to do with anything.
