Bootloop after recent Android OTA Update - Xiaomi Mi A2 / 6X Questions & Answers

Hello Community,
i have a Problem after the installation of the newest android Update (OTA).
The A2 just Boot till the white AndroidOne Logo and it hangs there after a time it seems it shut down itself.
My Device:
-USB Debugging is disabled, its a new testing device.
-I cant boot in recovery mode (vol-UP+Power) just boots to the white androidOne Screen and there it hangs
- I can enter fastboot(VOL-Down+power) mode and the device is listed when i type fastboot devices in my terminal on pc
- when i fire up MiFlash tool it list my device after clicking refresh, if i want flash the latest FW (http://en.miui.com/download-353.html) i get the error:
error:"Flash bluetooth_a error"
- My bootloader is locked.
Question:
How can I flash a offical Android with a locked bootloader?
is it a good idea? or better send it back for a warranty solution (i dont want wait)
is there another way to solve my problem? i really dont know whats the problem is. i did not rooted the device or anything.
would be lovely if someone could help me. with an instruction what i can try.
Thank you very much and have a nice day
Regards

If you have enabled 'OEM Unlock' setting in Developer settings, you will probably be good, you can unlock bootloader(oem/flashing/critical) and flash the official ROM ( as per now, 10.0.2.0 )
If not, you have 2 options
-Boot into EDL using short points and flash from there
-Warranty
Same thing happened to a friend's phone, it wasn't touched and just went brick after 10.0.2.0 OTA.
Guess everyone should enable 'OEM Unlock' in case this happens(Data Encrypted anyway, worst case stolen phone better than the chance of brick every time an OTA comes)
edit: If you want to save your data, you obviously shouldn't try the bootloader unlock way...EDL flashing allows flashing without wiping data, but haven't tested that personally

wow really? that are bad news...
thank you anyway :crying:
maybe someone other got a idea?
regards

Lot of users faced this after today's update including myself. Since my bootloader is locked, only option left is EDL flashing by connecting motherboard test points.

Just an advice for everyone reading this message from a Xiaomi Android One device: ALWAYS KEEP UR BOOTLOADER UNLOCKED, IT DOESNT MATTER IF USB DEBUG ISNT ACTIVE, JUST UNLOCK BOOTLOADER
sorry for caps, is just an important thing, i also had the issue but with unlocked bootloader i solved it easily

Just flash using fastboot

that seems not possible with a locked Bootloader (very new phone)
or can you provide a working solution with a locked bootloader? i wont use this EDL thing because its just new and i dont want open it.
Thank you all anyways

Same trouble here, we are fu...ed!

With Xiaomi mi flash tool, you can re active bootloader protection !
Simple flash with this tool with the option "clean and lock critical"
Works for me !

I'm in your same situation

Exactly the same situation here... Waiting for a solution without losing warranty.

I think if your bootloader is not unlocked, the only possible solution left is to shorting the test points on motherboard. Those who have warranty can return the unit for claim. Yet another mess up from Xiaomi and this will be my last phone from them.

I can understand that. I will claim warranty because its new and i dont want do that test point thing.
on private i would buy and recommend xiaomi anyways but if you want these hardware for some enterprise things then better not.
Iam out of this Thread now but if you want talk here some more feel free.. maybe somebody can bring a solution for all you guys who face this problem but i think its not possible without a open BL or the TestPoint Method.
Regards and have a nice day

Hi. I'm with locked bootloader. I received new January update. No change - stock variant updated to Pie. So it's safe to update or waiting for new one? Mi A2 4/64 micron ram

Some questions about flashing ROM so I would not end up in EDL again.

Hello, I have a few questions about flashing rom just to make sure I wouldn't end up in EDL mode again. First, let me tell something. I have bought my K20 pro on Aliexpress which come with a firmware that mark as MI 9T pro with bootloader unlocked but without TWRP install. I have tried to flash Android Q beta though fastboot without using the option Flash & Lock but i was end up in locked bootloader and then i got it fixed through EDL mode by paying someone from Russia who i don't know the name. Later on, I got another bad luck again by upgrading my official Chinese firmware through OTA and then the phone suddenly shutdown in the middle of the process which break both my recovery and fastboot so i have to go through EDL again. So, my questions are:
1. If i flash anything such as magisk, viper, or upgrade my xiaomi.eu firmware through TWRP, will something like my second story occur again? Or, does flashing through TWRP will brick both recovery and fastboot in the same or similar case?
2. After EDL mode, bootloader was unlocked by default so, what can I do to bind my MI account with the device? Because in case it locked again, then I can use xiaomi bootloader unlock tools to unlock it. In the first story, the device come with bootloader unlocked, and after flashed Android Q beta, the bootloader was triggered and locked so then I tried to unlocked it but Xiaomi bootloader unlock tools told me that my account is not bind to this device.
3. If i flash magisk, then do i need to always re-flash it on every system upgrade(xiaomi eu firmware)?

1. In theory flashing with TWRP shouldn't touch the fastboot or recovery partitions, unless you choose to. If you know what you're doing, then flashing with TWRP is reasonably safe.
2. You could try flashing an official Chinese fastboot ROM and locking the bootloader, then link it to your account. Don't try and install anything else, live with the official Chinese ROM and go through the normal unlock process. Once you've waited and got unlock permission for the phone against your Mi account, then unlock and install the ROM of your choice along with anything else.
But this does come with a small risk that the phone is still linked to the sellers account.
3. I went straight from stock to a GSI, so not sure about eu ROMs. If they have an OTA process that downloads then installs via TWRP (similar to official LOS), then it's possible Magisk will re-install at the same time. Someone who uses eu ROMs will need to confirm what happens.
For anything else, you'll needed to re-install Magisk.

I believe it is a risky method because if the bootloader is locked the phone might brick again and I have to do EDL again too. I wish if there is a safer method, because I experienced EDL mode twice already and it is terrible and need to pay lot of money just to fix it. :crying:

Flashing an official fastboot ROM in the Mi Flash Tool and selecting 'clean all and lock' "shouldn't" brick the phone. If you're on an official Chinese ROM, then going through the standard unlock process "shouldn't" brick the phone.
The biggest risk in doing this would be finding that the phone is still linked to the sellers account.
If you want to be able to unlock the bootloader with your own Mi account, should it get locked again, then this is your only option.
However, you could leave it as it is and just make sure you never lock it again.

Thank you very much for help. I have read both but unfortunately i can not UNLOCK my bootloader… when i was trying to unlock the bootloader through MI UNLOCK, it says "Current account is not bound to this device". Otherwise if this was succesful and i could unlock it, then it would be easy i believe.

Since you locked the boot loader, you'd have to flash (with fastboot) using the same flavor of miui which was installed. (example: chinese or eu variation), otherwise you won't be able to boot.

Yes, that i understood… There was EU variation with unlocked bootloader, which i do not know why, but okay…
But now i can not unlock it, it says, when i try to unlock it though fastboot with mi unlock, it says "Current acount is not bound to this device, ADD your acount and device in MIUI"s setting > developer options> mi unlock status.. but obviously i can not do it since i can not turn on my phone, its stuck on recovery mode.

I can help you
First of all you need chinese mi assistant
Second you need try three versions of roms(eeu , china , global) but im pretty sure that your phone is chinese version that bought from gray market and they unlock bootloader to install global rom
After you download these tell me, i guide you
Be sure download recovery rom (not fastboot)
It has .zip extension not tgz

If you know how to sideload the rom then everything is become okay dont worry
After successful debrick you must bound you mi account to your phone and wait for bl unlock then reflash with mi flash tool and global rom
AND DONT LOCK YOUR BOOTLOADER AGAIN
Yes, unfortunately i do not know how to sidload the rom... But when i have Chinese rom downloaded then what do i do with that? I connect the phone through mi assistant and there it can be flashed?
I had the same thing happen. You need to force a firmware flash ?
I had someone on xda recommend an excellent recovery tool.
It's called 'miflashpro'. It can be hard to find the English version. I did eventually but actually unbricked my Mi9 with the Italian version.
99% chance your cell can be fixed this way
bricked too
I'm having the same problem here, after wipe in twrp mode my phone restart and i'm blocked on bootloader screen.

I did the same thing with a Mi CC9 relocked the bootloader by mistake thinking it was like any other android phone. Did you have a Xiaomi account associated with the phone and signed into after enabling oem unlock in developer options.
If tha'ts the case you can use https://en.miui.com/unlock/ tool from where but it checks your phone number to see whether its associated with mi unlock.
Otherwise you will have to use EDL method which involves disassembling back of phone and shorting out two pins to initialize EDL data transfer but you need a EDL associated account this (belief xiaomi has revoked everyone access to these)
Hello all members.I had same problem and I open this phone with suport from youtube .I try clean some connector and worming cpu and motherboard. After change the battery with new. When close the phone they suprised me and working good.After 10 hours again close and bricked. I try sake and again open .So....the real problem its not CPU and motherboard but some connector dont touch good. Sory for my English. I hope some other find which connector have problem in this phone and pm me. Now my MI 9 working good but I keep bickerful ...

Bricked Mi 9T Pro

Hello. I flashed Global ROM over European ROM. my phone bricked, system and recovery is destroyed, I have only access to fastboot. I tried to unlock it and mi unlocker tool says I need to wait about 120 hours. My question is, will it unlock after that period time even when the phone is not in use and turned off? Because I don't want to open the back and pay for EDL flashing. Thanks.

As far as I know it should unlock OK. I personally haven't done this, but there are accounts on these forums of others who successfully unlocked the phone after the wait period in the same circumstances as you. If you were going to have problems you wouldn't have got as far as getting the wait period.

Your bootloader locked itself when flashing? Or you ticked to lock bootloader?

I flashed it via XiaoMiTool v2. It was OTA Package. And now when I successfully booted into Global ROM, I can't flash back EU ROM like Global before. I had all the time locked bootloader.

Question Help, i did something stupid.

Hello
Hoping somebody can help getting my phone up and running again.
I wanted to unroot my phone, because i was having issues with danish "MitId". And was a bit sloppy with it.
First i tried using SuperSU to remove root. Because i didnt feel like setting everything up again. Didnt work.
Then I locked the OEM Lock in developer settings. Not thinking this would be a fatal error.
Got home from work, and said to myself. Jusk lock the bootloader and the phone will reset itself.
But this is not the case, when you have been stupid enough to lock the OEM lock.
Now I am stuck on "No valid operating system could be found. The device will not boot"
I can get in to fastboot by pushning power+vol down. But cannot flash anything since the phone thinks the OEM Lock is locked on it.
Does anyone know of a solution for me. Or is it going to the shop tommorow and say that my phone is going this. And hope they will sort it for me?
Can't you fix stuff by using https://flash.android.com/ ?
No, unfortuantly not. It fails:
Device Unlock Disabled​For security reasons, you need to enable "OEM unlocking" in order to flash your device. See the device preparation instructions for more information.

Try sideloading the full OTA. You don't need an unlocked bootloader for that.
Unfortuatly not, if I try to enter recovery mode. The phone just goes back to the screen saying "No valid operating system could be found. The device will not boot"
ADB is not available to me
If you can't sideload the OTA, I'm afraid there is not much else you can do with a locked bootloader except try to RMA it.
Can you get into recovery at all. Even if it's the stock you can attempt a sideload of the stock OTA.zip from Google. You may also try if your on boot slot A
fastboot --set-active=b
On b use
fastboot --set-active=a
Try to see if the other boot slot has an a bootable OS.
*****I apologize I just saw it's actually still locked****"
Contact U-break I-fix if I typed that correctly. The third party warranty repair center for Google's warranty. I believe they can attempt to switch the boot slot with a locked bootloader with the equipment they use to reflash these devices. If anything it's under warranty get the RMA and if the bootloader is locked on it trade someone or sell it and use it to make buying a new cheaper..

No, I can get into fastboot and that is it.
But everything I try in fastboot gets rejected, since it says the phone is locked.
Does the bootloader screen on the phone have the option to boot into Rescue. This has a ADB connection but I am not sure if adb sideload works
Really mad that Google intentionally locks phones this way, turning them into completely functional, but useless piece of junk. I guess that's late stage capitalism for you xD

Google is not responsible for phone's with locked bootloaders. They make the device with the specifications the carrier that sells it stipulates. Google themselves allows the unlock.

Iam guessing the same. Phone doesnt want to do anything.
And since i cant get into the phone to oem lock i am stuck. Live in Denmark, so by law I havnt voided the warrenty by rooting.
Pixel warranty is always valid even if you unlock and root. Google doesn't void the warranty. Go to Google pixel support page. Find warranty and act as if your submitting a RMA and it will tell you after you enter the device IMEI how long your warranty is valid for
Delete
If that were true. Android flash tool https://flash.android.com/welcome
Would work as it's the same process for the browser to flash the very same file. Motorola allowed signed factory img on locked. Google had never allowed that in fastboot as far as I am aware
DroidRommer said:
All you need to do is go here Factory pixel firmwares and scroll down to pixel 7 panther assuming you're not on the pro (cheetah)
-select the latest version for your model whether that's Verizon or whatever if you have the carrier unlocked one like myself just choose the Feb firmware that doesn't have a carrier name at the end of the firmware number (you should have your phone plugged into your PC and in fastboot mode) click flash and follow the steps. These are Googles factory images so it doesn't matter if your bootloader is unlocked or not as long as you choose the latest version and the correct version for your phone. Tbh you can't really brick the pixel 7 as long as you have a PC and are able to put the phone in fastboot mode (holding the volume down and power button while powering on)
-Anytime you run into some kind of bootloop issue or wanna get rid of root flashing the stock firmware from this website will factory reset and revert your phone to the way it was the very first time it was pulled out of the box and powered on. If you have already tried this and you know forsure you did everything correctly then I must admit I have never had this happen and I'm someone who flashes custom roms and goes back to stock to get the latest security update just to turn around and flash another custom rom right after lol. If you need any help or advice feel free to pm me whenever. I have been rooting phones for a long time and have to say that the Google pixel is by far the most user friendly phone I've ever owned when it comes to custom rooms, rooting etc. You can ALWAYS go back as long as you know what steps to take. Sorry for the rant especially if you already figured it out.
Happy Customizing!

Their bootloader is locked. You cannot flash a factory image like that with a locked bootloader. They also turned off OEM Unlocking in the developer settings. If they had left this enabled they would be able to use Android Flash Tool as that tool will unlock your bootloader if OEM Unlocking is enabled.

This wouldn't be Google, they basically encourage you too unlock the bootloader and root if you want as they give you all the tools you need and factory firmware options to go back if you make a mistake. Tbh if you are able to unlock and root the phone to start then you can go back. Even with a locked bootloader you can always flash the latest factory image on googles dev website, you just can't downgrade firmware or install different carrier firmware without the unlocked bootloader. If we really wanna poke at some phone developers I vote Samsung as I have had multiple people ask me to root their phones and if it's a US snapdragon version it cannot be done its so frustrating lol thanks for letting me vent, have a great day if you have the the carrier unlocked dev edition of the pixel 7 and ever need any help feel free to pm me. I have been rooting and romming pixels for a long time
Edit: I was not aware you couldn't flash the stock firmare using googles dev page without oem unlock. I apologize for jumping to conclusions. I thought I had every possible bad scenario happen to me by now but apparently I learned something new today.

Even with a locked bootloader you can always flash the latest factory image on googles dev website, you just can't downgrade firmware or install different carrier firmware without the unlocked bootloader. If we really wanna poke at some phone developers I vote Samsung as I have had multiple people ask me to root their phones and if it's a US snapdragon version it cannot be done its so frustrating lol thanks for letting me vent, have a great day if you have the the carrier unlocked dev edition of the pixel 7 and ever need any help feel free to pm me. I have been rooting and romming pixels for a long time

Dude. You cannot flash factory images of any kind on any Google phone with the bootloader in locked status. Please stop giving false information on here. If you want to talk up Samsung do it on a Samsung post. Let's not confuse everyone please

To use Android Flash Tool, you have to have OEM Unlocking enabled in Developer Options for it to be able to unlock the bootloader.
To flash the factory image in fastboot you must have an unlocked bootloader.

Their bootloader is locked. You cannot flash a factory image like that with a locked bootloader. They also turned off OEM Unlocking in the developer settings. If they had left this enabled they would be able to use Android Flash Tool as that tool will unlock your bootloader if OEM Unlocking is enabled.

Okay my bad you are right fortunately I have never had this happen. And like someone else said if he can't get into recovery then he can't sideload a factory ota... sorry I'm at a loss on this one. Some custom roms use "fastboot update file.zip" would that do anything in this case or would that command not even work with a locked bootloader I'm assuming. I apologize for trying to act like a know it all I've just never heard of this happening

Redmi 9C bootloop issue

hello, i have a problem with my redmi 9c
my phone just started bootloping alone, i went to sleep and i woke up with my phone dead
the phone is stock, no root, no custom recovery and still with bootloader locked because i don't need features who need it, i can access fastboot but recovery is not posible to reach because Vol+/Power is useless, the phone do nothing pressing those buttons, only with Vol-/Power, so i can't make a factory reset or wipe data, the only thing what i did a couple of hours before the phone broke was change my security pattern (i don't think it's related anyway...), and it was 8 or 10 hours before the issue. sadly the phone warranty expired in january and i have nothing to do at this moment
the phone stops the bootloop after draining the battery, with the bootloader locked of course i'm unable to flash a stock rom, even with MiFlash
what could be the problem?
thanks! (and sorry for my bad english, spanish native here)

Hi, my first guess would be faulty hardware, for example a dead motherboard.
Is there any error when attempting to flash the Stock ROM with MiFlash? Afaik you should be able to flash Stock ROMs even with locked bootloader.

Thanks for the quick reply
MiFlash said "not allowed in locked state" and I guess it's because of locked bootloader, I should try with a specific stock rom?

Hmm okay, yeah that sounds like it's preventing you from flashing simply because your bootloader is locked.
Which Stock ROM did you try? Same as the currently installed version or an older one?

I tried with the last available rom and the previous one, automatic updates were disabled, but I know I updated the phone after buying it
I don't remember if the phone was running last version...
MiFlash should let me flash the phone with the same installed ROM even with bootloader locked?

If you tried an older firmware, it's possible that it didn't flash because of Xiaomi's "Anti-Rollback" Feature which exists to prevent users from Downgrading.
But yes, it should let you flash the same version afaik.
What Region is your Device? On Locked Bootloader you can only flash Firmwares that are from the same Region. (For example Global or EEA)

Alright, have you btw tried flashing directly via fastboot?
Meaning opening terminal and from there flashing all partitions one by one for example "fastboot flash boot boot.img" ?

Oh okay then.
If in the worse case nothing works, your last (paid) solution would probably be to contact one of these "Mi Auth" Guys on Telegram. They have acess to Authorized Accounts that are able to flash your Phone in EDL Mode (might need to open your phone to short test-points though)
I had to pay them about 20€ to get my old Mi 11 (which I sold a while ago) running again after it got stuck in EDL Mode. :/
