Please Help_After OTA Update Xiaomi Mi A2 died

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.

Phone hardbricked, any chance at recovering it?

So my phone's stuck in fastboot mode, oem unlocking and usb debugging is off, recovery mode doesn't work, and a custom rom was installed when bootloader was turned off, so is there any way to at least get the phone back to stock, or is it just useless now?

Since your phone is Qualcomm based, then you should have EDL mode in your device.
Have you tried it? There are multiple ways to boot into EDL mode, like adb reboot edl or the EDL cable method.
I don't know if it is unlocked by default on your device or you need unlock key first though.
If it requires unlocking then you have to send your device to an authorized service center, not just any service center.
If it doesn't then you can easily find guides on the internet about how to unbrick your phone with EDL mode.
Goodluck.

Yeah I've tried entering it with the command, didn't work, but I suppose I could send it to a service center for it to get unlocked. I've heard other people have their phones enter EDL mode and other people saying it's basically useless though which was why I was slightly scared about entering it but I'll give it a shot, thanks.

EDL mode doesn't have a UI, if you enter the command and get black screen instead chances are that you're already in EDL mode.
Similarly if you turn off the device and leave it like that for a couple of minutes, some Qualcomm devices can detect that it's bricked and enter EDL mode automatically.
Alternatively you can just make your own EDL cable to force your device to boot to EDL mode, follow this thread here.
Or just get an EDL cable, they're cheap really.

EDL mode is very low level and very powerful, you can literally do anything to your device with EDL mode the sky is the limit. However it requires special Qualcomm EDL tools which depend on your Qualcomm type (sahara or firehose) and correct driver.
Beware that EDL mode commands are very powerful and can mess anything beyond repair. So be careful with whatever command you use while in this mode if you're not sure what it does then don't use it. And send it to an authorized service center instead.
You can extract data with EDL mode and I recommend doing that before flashing anything.

Be careful of unofficial EDL tools, most are just trojans for the desperate.
The official tools are already on the internet. I don't recall the exact name but i think it was something along "QSPT" or something. Sorry for not being of much help.
I'd have searched for the correct tools for you, but it's getting really late here.

Yeah for the first part when I did the command it just said "unknown command" so nothing happened, but yeah I was thinking about getting an EDL cable, would any cable work or would only a specific type work? Also how would you know what the qualcomm type is?

I worded this poorly my bad, what I meant is sahara and firehose are actually firmware boot type and it doesn't matter what tool you use as long as it is meant for Qualcomm devices.
Any EDL cable should work, and as for the tool it's QPST or QFIL.
As for the driver: Qualcomm driver link.
They say QFIL is much easier to deal with as it is standalone, anyway both work similarly.
As for the deep flashing process, you can follow this guide here.
The guide has updated driver, QPST and QFIL links.
For the firmware images I only found this one and it doesn't have Qualcomm firmware in it, in case you need Qualcomm firmware you need to follow the guide I gave you to extract the firmware from another RP2. Here is a video guide on how to extract qualcomm firmware with QFIL.
EVERYTHING I JUST SAID IS TESTED, HOWEVER I DON'T HOLD ANY RESPONSIBILITY SHOULD YOU PREM-BRICK YOUR PHONE.
Hope i helped. And goodluck.

I forgot to tell you how to use EDL mode to extract data, here is an article.
It might be hard to understand at first but you'll get used to it. It's completely safe so you can mess around as much as you want, Don't click random buttons though. Note that: The openpst tool isn't a flashing tool and only meant to communicate with Qualcomm devices in EDL mode.
Here is a different method, although it's meant for Xiaomi devices it's still generally for Qualcomm devices.
Just follow step 7 only. Obviously you won't be using MiFlash nor flash a MIUI ROM.
After flashing the ROM flash a custom recovery to backup your data.
Then delete all data including dalvik cache.
I can't confirm if those methods are tested so follow them on your own risk. However I suggest trying the second method since the extracted data from the first method would be encrypted therefore useless. Unless you know how to decrypt it.

Phone stuck in 900e mode (hard bricked)

Hello, I've tried everything about my bricked redmi 4x, i can't get it out of qualcomm 900e. I've done test point method, edl mode method and all combinations of them. I've also read this thread and nothing helped. The reason of brick is installing unofiicial rom. Is there any chance to make him alive?

Ok, i finally get into fastboot mode, but my bootloader is locked, is there any way to unlock it? I've tried a lot of programs, but bootloader status is still false.

hi there! i also have the same problem. im stuck at edl mode, 900e , sahara mode, can u help me how to get into fastboot mode?

I was trying to get out of 900e mode like 1000 times and then i succeed to get into fastboot mode and it worked (i don't know why it didn't work earlier). Now i can't boot a new os because the bootloader is locked and i don't remember mi account password (trying to log in by xiaomi mi tool v2).

i manage to get out of 900E mode, by looking for a test point on my device, opened her up and look for the test point jumper, kinda pretty easy. dropping this method here in case someone got hard bricked.

HELP!!!!!! Any unbrick tool for cn rom?

Hey guys,
I need some assistance as I am not able to unbrick my RM3 with unbrick tool. Multiple times I have already got it worked, flashed many times, but this time I am not getting my phone started. Normally, I use the NON-EU unbrick tool, all goes well but this time, it says THIS DEVICE CAN'T BE TRUSTED, WON'T BOOT UP. After multiple tries, I tried that EU unbrick too as well, but the same result.
I think I have locked the bootloader while on CN Rom 5.14, most probably this is the only reason, I was doing some tweakings and got it bricked. Anyone here who can tell me if there is such thing named CN Unbrick tool or any other way around to get it worked. I can enter FASTBOOT and EDL Mode but recovery mode showing black screen and adb is not recognising as didn't enable USB debugging. please help...

Question Blackscreen loop booting

Hi,
I'm stuck with my phone: it still loopbooting every 5seconds, black screen, only retrolight.
Bootloader is unlocked. I wanted to install twrp, but fastboot says partition recovery not existing.
After reboot, i'm stuck with this mod.
Try to press volume - to go again in fastboot : phone is detected by computer, then disconnected because it's rebooting.
Do you have a solution to try for me?
Or what are EDL point? I've tried to make an ELD cable but did not work either.

How long is your bootloader keeps active? If it's about 5 - 10 seconds, you can try paste the command to flash stock recovery. I attached it if it's possible to do so (from the latest global). And by the way - THERE IS STILL NO ANY CUSTOM RECOVERY for our device, sadly. Actually there is some, but only mouse works.
The commands to paste:
fastboot flash boot twrp.img

twrp.img

Boot.img in this case, doesn't make much difference

Sorry but my bootloader don't stay active long enough. I just ear usb detection from PC , then one seconde later, usb disconnection sound.
Phone is still loop booting.

Can you try then pasting "fastboot oem edl" (emergency download mode). The screen should turn black

After that flash with Xiaomi Flash tool

I'm unable to enter in FastBoot mode.
Phone booting black, and every 5 seconds , reboot.
If i push "volume down " button, i hear it vibrate, but nothing. Reboot and not detected by fastboot.exe
I think i have, with all manipulation , relocked the bootloader.
My only way, will to find a way to boot in EDL mode.

Test points, which are unknown so far. You have to disassemble the phone, tho. And you can try to find these points yourself, at your own risk obviously. If you will succeed, pls tell me. We need to know the test points.

I was exactly in same trouble, use This guide that solve the issue.

Press mobile three buttons and connect cable to pc to enter brom mode. Because mtk models don't have test point. So don't need to open mobile.

EDL mode in Xiaomi mediatek are called BROM mode. Don't need to disarm the mobile.

Thanks !
