Xiaomi has auto bricked after update- need help - Xiaomi Mi A2 / 6X Questions & Answers

Hey guys, i have MI A2 cellphone, and after auto update programmed to three hours the smartphone show "AndroidONE" logo and then shutdown, i tried "Fastboot oem unlock", but it is my output:
PHP:
C:\Users\Lucas Daniel>fastboot oem unlock
FAILED (remote: 'Flashing Unlock is not allowed
')
Finished. Total time: 0.000s
. I'm desperate, I do not know what to try anymore, I believe I do not have unlock OEM activated, someone can help me?
Sorry for bad english, i'm from brazilian.

@LukeSkyPTBR
It's a well-known issue. One update was revoked as soon as Xiaomi has found out about phones bricking once it's installed. There's no way you can fix it by yourself except if you have ordered your phone from China (and so no warranty you have) and have experience in disassembling phones. There's a thing called test-point, do some research if you are self-assured in that area. Otherwise let your authorized service center make everything for you. It is a warranty case, either way.

Thanks, looks that, unfortunately, my unique solution is test-point for activate EBL Mode... I will leave the topic open for the case of i get other solutions... after 3 days, if not get, i will close and the unique solution will really test-point.

Try rebooting it a couple of times and see if it boots. Or plug it to a charger and try booting it once it starts to charge successfully. If all fails, flashing via EDL might be your only option.

Try rebooting more than couple of time. Phone is supposed to switch to the other slot of A/B where original ROM (before update) resides. When it finally boots, get developer rights, switch on ADB Debugging and OEM unlock, thus next time update soft-bricks your phone you'll be able to unlock (or even better unlock immediately after successful boot not to loose your data in future).

Isnt Fastboot OEM Unlock command deprecated ? Shouldn't you use the unlock / unlock critical command ?

How can I do it? I leave the phone in the charger for a long time? Or do you need the power button for a long time?
I tried to press the power button for 2 minutes and nothing happened.
When i leave the smartphone on the charge, after 50 minutes, show for me 100% percent, so, i pressed power button and the screen stayed lock in "AndroidONE", nothing happened, until try again press power button.
The problem original comebacked to me

Can't you just enter fastboot mode by holding power and vol- keys with phone connected to a PC?
(Or power and vol+, can't remember)

I can enter fastboot mode, but this is not enough to do run commands up. I would need unlock bootloader(OEM).

If you can enter fastboot then you can go to EDL mode by typing 'fastboot reboot edl' and then use QPST to flash the latest stock rom.

Do as tabun1994 said.
This will hopefully get the system up again.
The commands I wrote would unlock the bootloader. What else could I have meant?
If you succeeded with tabun's method, then you probably would only need to enable "USB debugging" and "OEM unlocking" in the ROM's developer options (which you'll enable by hitting "build number" in settings like 10 times or so).
Then you would connect the device and accept the 'trust this device' warning.
After booting to fastboot now, the commands I wrote should work and unlock the bootloader (if you even want that when your system is running again).

This command needs OEM Unlock :/
this is my output: fastboot: usage: unknown reboot target edl

The test point method is actually easy , you have to dissasemble the display , easy procedure , remove the battery and short the two test points with tweezerz or something ,and in the meantime you plug the usb cable into the computer. It should install the Qusb_Hub drivers , and with miFlash you should be able to reflash the firmware . I bought a phone that was in this state and fixed it using these steps.

No more solutions, I will do the test point method, thanks to everyone who tried to help otherwise.

No it doesn't, i have tried this method on locked bootloader, go to this link - https://forum.xda-developers.com/an...e-how-to-reboot-to-edl-fastboot-t3394292/amp/
And download the fastboot_edl.7z , your phone will be in edl mode, I think you don't have the proper platform files which has caused the problem.

Mi A2 bootloader relock bootloop, need help ASAP!

Hay soo i wanted to relock bootloader after failing to install custom recovery (both) i turned off oem unlocking in developer options and did fastboot oem lock. Now the phone is looping in "your device can't be checked for corruption. Please lock the bootloader" and it reboots and says the same again.
When i try to unlock the bootloader with fastboot oem unlock i get "FAILED (remote: Flashing Unlock is not allowed)
I really dont know what to do and i need a phone for comunication. Please help!
You should only lock the bootloader after installing the stock ROM, otherwise your device will be bricked and the only way you'll get it back working is by flashing the EDL test points near the phone's battery and reflashing the stock ROM back in EDL mode.
Try downloading this tool then try to unlock oem, flashing and flashing critical.

I really messed up here. The problem is i toggled allow oem unlocking off and to top it all off i did oem lock. Now its bootlooped (check the video). Does xiaomi fix this by warrenty? I really dont want to open the device up because i am afraid i will do more demage and void the warrenty and the device wont ever be fixed.

I have seen another guy who did this. How is this possible that you turn off the unlock bootloader option when you've already unlocked it? The option gets greyed out and becomes non-functional.
Anyways I guess the best option is to give your phone to Xiaomi for the fix.

It wasn't grayed out for me. I'm thinking of test pointing the device because i dont really want to wait few months until i get my phone back from service. (There is no xiaomi service in my Country)
But i'm afraid if i open the device i will void my warrenty for future.

I don't think you will since you don't need to disassemble the device, all you need to do is remove the aluminum back cover carefully with damaging it and you'll find the test points right besides the battery

Why not use oem unlock?

Stuck at Bootloop with Bootloader locked.

Can anyone help me how to unlock the bootloader via fastboot since I cannot get in the software as I have a bootloop. I greatly appreciate it as I have been figuring out this for the past 5 hours. Thank you.
Hello Guys, I messed up as I did not unlock bootloader first before flashing it from fastboot. Now I have a bootloop. Can anyone help me how to reflash CN. I have a lock bootloader. Thank you very much.
Anybody?? Please help.
Any other phone if you don't flick oem unlock first in developer ootions it's a hardbrick. The Asus unlock tool apk does this. Did you install that first and unlock first? Hope you can recover

Your only option is to go to ASUS service center in your area and ask them to repair it. If they accept to service it they will of course charge you for it which is better than having a bricked phone. Other than that your only option is to send the phone back to China there you can claim that the phone got a bootloop and since you didn't unlock the bootloader you are still covered by warranty meaning you will only pay shipping fees.
Thank you Rashad83. I just sent it to Asus Service Center with a fee.
Did you guys changing the Boot Slot?
Check your current boot slot by hitting -
fastboot oem device-info
Then change the slot to "B" if you're currently in "A"
Slot change command -

Guys, Please obtain an ASUS Raw firmware to recover your devices. Do not fall for tricks by various users around which asks to pay for them.
Just use Google and find yourself the correct RAW firmware for your model.

Hi, I've managed to unbrick my ROG Phone II Tencent Edition 8/128 with a locked bootloader having "slot _a" error. Link to other thread: https://forum.xda-developers.com/rog-phone-2/how-to/repair-rog2-phone-edl-modeofficial-t4012175
My equipment for flashing, for sure you already have ADB installed in your computer, my computer is an x64 Intel Windows 10 laptop, I used USB 2.0 not USB 3.0
Credit to @johnny886 for the sharing the tool,
"If your phone can only enter EDL mode (9008 mode)
this firmware is glad to help you. It can be flashed in through
the QPST tool, or it can be flashed in through the Xiaomi miflash tool.
To use the QPST tool, you must change the EMMC to UFS. No matter which tool you use, -(I personally did not use this, I just downloaded the file and followed grewookie's instruction below)
you must restore the factory settings after the phone is turned on, otherwise the storage
of the phone will recognize the error! !! !!
Factory settings must be restored after booting! !! !!
The firmware is made through the official package UL-ASUS_I001_1-ASUS-16.0631.1910.35-1.1.207-user.zip
without any modification, Suitable for repairing phones that can only enter edl mode(9008 mode).
File Downlaod link: https://drive.google.com/open?id=1Pk...Sf6cDq7SuJiBBu"
Credits to @greywookiee for the super clear instruction:
"Here's some instructions I put together that would have helped save me a lot of time. Please correct anything I missed:
After you have downloaded the zip file, here are the step-by-step instructions:
1. Extract the zipped folder wherever you want on your PC.
2. Open a CMD window.
3. cd /d <whatever path it is to the "\ASUS_ROG2_ZS660KL_QPST_Firmware\images" folder> e.g., "cd /d D:\RogPhoneII\ASUS_ROG2_ZS660KL_QPST_Firmware\imag es"
4. Make sure your PC is connected to the side port of your phone and the phone is in fastboot mode (Volume UP button + Power button).
5. Check and make sure your PC is connected properly by entering "fastboot devices" in the command window. You should see the ID of your device.
6. Then enter "fastboot oem enter-dload" in the command window. This will put the phone in emergency download mode (EDL). My phone went all black.
7. Open "\ASUS_ROG2_ZS660KL_QPST_Firmware\MiFlash2018-5-28-0" folder. Launch "XiaoMiFlash.exe".
8. Click "refresh". You should see a device in the list.
9. Click "select" and navigate to the "\ASUS_ROG2_ZS660KL_QPST_Firmware\images" folder.
10. Click "flash". Wait until it says "success".
11. After it's done, you'll hold down the UP button, Down button, and Power button on the phone at the same time until it shuts down.
12. Hold Up button and Power button at same to boot into fastboot mode again. Select Recovery mode by using the Up/Down buttons on the phone. Press the Power button to select.
13. Select "wipe data" from the drop down list. Go down the list of "no" until you get to the "yes" and press the Power button.
14. Select "reboot now".
15. Done."

edl mode 9008 v40 very easy

(french) hello
I could not start in edl mode with the xda instructions but I found a videos
phone on android, connected to the computer by usb. you keep pressing the power button and the volume down button.
when the screen goes black immediately you strafe the volume + button for 2 sec.
the secret is the windows song if the phone is on. when you hear windows song strafe the volume +. i know I did it with my phone off and my phone on quite a few times
normally your computer will recognize the phone in the correct mode. if there is a problem do not forget to install these drivers and restart the computer as it will stay in edl mode and will be well supported.

But you can get to fastboot, just not the way you read on the internet.
The device doesn't have fastboot available, until, you put it in edl mode and use qfil to flash the 'engineering' abl. That's what gives you fastboot.
You could, at that point, use fastboot to get the info for unlock.bin. But why? because at that point you can just type 'fastboot oem unlock', and it's unlocked.

Unlock only works with Oreo ??
I have Pie
How do I downgrade without root ?
Is it possible ?
If I can flash a firmware without root
I'd be more than happy to flash a custom rom which has LG's apps instead of Google annoying ones.

you are like me your phone is "bricked". your phone don't have download mode, fastboot mode. maybe you have

Question Black screen and hard brick

Hello everyone today i flash an incompatible rom with twrp and my screen turn completely black After reboot twrp in recovery .
Do you have solution ?
Sorry for my bad English
Hi if you can open bootloader, flash stock rom
The easy solution is press power+volume down. Phone should boot into fastboot mode. Then flash fastboot ROM without relocking the bootloader.
The other way is taking phone to service center. They'll flash stock in edl mode.
I can't seem to put it in fastboot mode. but by pressing the 3 buttons or by changing the buttons I managed to put it in something else I think that at times I manage to put it on a fastboot but the screen always remains black impossible to know i have this message in device manager (Unknown usb devices request for descriptor) do you think it causes me to reinstall drivers what could be the cause? how to adjust as soon as i can connect it so l is not a Qualcomm USB hs 2008.

Doesn't EDL need authorized mi account these days? It'd better to visit service center because installing EDL driver & all the fuss will be useless
May be you can find some drivers which can recognise your phone to work with ADB in fastboot and flash a new ROM. If that doesn't work, then a service center is the next best option.

Sounds like your device boots into EDL mode, likely due to a corrupted bootloader from the incompatible firmware you've flashed. If you have the EDL firehose files for your device, you can use QFIL to flash a compatible ROM, alternatively try to EDL flash the boot partition with a working boot (that may get you from EDL to a soft brick with a working bootloader and Fastboot - from there you can try try and flash a working firmware).

I unfortunately tried to install all the drivers but nothing has worked difficult to know if a fastboot is started it's a hassle when the screen is completely black even with the task manager open I don't I did not succeed finally I ended up paying someone who had me unlock my phone it cost me 29 € my phone is now unlocked which I can advise on the other hand for those who would like to install roms or root their phone is good it is to wait until no auth file is leaked

I see it's super interesting as information I did not know that we could flash only a partition with QFIL.
Unfortunately I could not find the firehose files for the phone as the phone is probably very recent.
I had to pay someone to unlock my phone with an edl account of course .
My work now
Was the unlocking done in person or online? Anyways glad to see it's sorted out.

Turn off your phone.
Press and hold the Power + Volume Down buttons together and immediately connect the device to your PC. You need to time it perfectly.
It will automatically boot into EDL mode.

Try getting into fastboot, and:
Code:
fastboot reboot emergency
If you don't succeed, then the phone itself doesn't have EDL mode.

Yes, I think this phone doesn't have EDL mode.. But, FYI the command is correct, but it still go straight to the OS..
F you Xiaomi, what is your goal to make us to wait 168hour just to unlock the bootloader??? F YOU!!!
If you still have warranty you can get fixed from a Xiaomi service center for free, however if now I'm sure they'd still fix it maybe for a small fee
try:
Code:
fastboot oem edl

All Qualcomm devices have EDL mode, on locked bootloader, you can't boot as easy as pressing any buttons or through ADB/fastboot commands, you need to unlock it firstly, or using the test point method.
In all my previous unlocked Xiaomi devices I have booted to EDL mode by pressing both volume buttons, I didn't try it with this device though.
