some help to unbrick - Xiaomi Mi A1 Questions & Answers

hi, cause of my work (pc and smartphone engineer) i fix only hardware. But there are some very rare cases that some people trust their phone to me to unbrick it when nobody else here at my town can.
So now i have to fix a xiaomi mi a1 which is hard bricked and the customer didn't allow bootloader unlock in developer settings.
It doesn't boot and so it doesn't allow me to fix it in bootloader mode (not allowed to flash partitions).
In EDL mode i get errors too.
What i need is some guidance how i can fix that xiaomi and any xiaomi when that happens.
Let's start with mi a1 now.
Which mode should i use ? (i guess EDL)
And which stock rom ?

Nevermind I fixed it on my own. Booted to edl and flashed all the partitions there.

[HELP] Can't unbrick my mi a1

Hi everyone. Yesterday, I flashed Mi5X rom on my mi a1 and now it's stuck on boot page saying "The system has been destroyed. Press power button to shutdown. I can still enter into fastboot mode but my bootloader got locked itself ( it was unlocked before). I tried unlocking boot loader using "fastboot oem unlock" command but i got error
"FAILED (remote: Token verification failed, reboot the device)". I also tried to flash stock rom using mi flash tool but again but flashing completes in 0 seconds. When using another rom file i got error: "error Mismatching image and device". i tried another rom but it also got flashed in 0 seconds. So if anyone knows something then please share with me. It will be a great help to me. Also tell me if i did something wrong in the way. Thanks.
Why would you flash Mi5X ROM on Mi A1? Guess you cant get into the recovery or can you? What do you get if you type fastboot devices?

First of all I thought that both devices are similar so I flashed Mi5X rom on my mi a1. I can't get into recovery mode. And fastboot devices command recognizes my mi a1 . I have no problem in getting my mi a1 into fastboot mode and connecting it to my PC.

Thats interesting... what about getting in EDL mode? There you can flash stock ROM. In EDL mode you dont have to unlock bootloader to flash.
Try to use EDL mode, there is a guide here

Dont ever to flash Mi5x rom again, the hardware is similar but not the same, we MiA1 use A/B partitions.
The reason the fastboot OEM unlock command no longer works may be that you flashed an MIUI ROM onto your phone and that command isn't how you unlock the bootloader on MIUI. My understanding is that you need to request unlock permission on the Xiaomi website and after you get verification that it's been approved you use their unlock tool to unlock the bootloader. If you manage to get the bootloader unlocked then you can hopefully use the MI Flash tool to restore your phone to stock.
like someone said already use EDL mode.. https://www.youtube.com/watch?v=70hYUCjAsCM
and if you have updated miui EDL could be blocked here is miui forum post about it http://en.miui.com/thread-1680467-16-1.html
best of luck.
edit : I revived father's redmi1a once using testpoint.. nasty but works out ok, if you have a PC , cable and drivers needed..
earlier MI allowed use of EDL cables but with new miui they removed this functionality from bootloading
Since you can get into fastboot, try the following command to go into EDL:
fastboot oem edl
MiA1 is a **** low tier phone. Big mistake if you buy it!

It's a good cheap phone for people who can't afford a flagship. It's also priced at what it's worth. New OnePlus & Pixel phones cost much more than they are actually worth based on build quality and resale value after 1 year. You can easily buy a refurbished or used Pixel XL ($1000 list) for $200. I paid $800 (including sales tax, shipping and insurance) for a new OnePlus 5 and got $270 when I sold it 8 months later and threw in over $100 in accessories. Buying an expensive flagship phone that loses most of its value within a year is the big mistake.

The number one rule for any phone is don't flash stuff if you don't know what you're doing. If you flash an incompatible ROM on any phone you're going to brick it. That kind of user error can't be blamed on the MI A1.

This I completely agree with. I have a similar problem with Mi A1 but I flashed the Official fastboot ROM and now it's bricked. Here is the full detail:
Hey, I have a question for you since google can't help me with it, trust me, I tried.
I have a Mi A1 device and after I flashed the latest Oreo update (official) on it, it went into a coma (bricked but not dead), i.e. the phone kept vibrating every 1 second when it's connected to PC or when I push the power button. Can't get to fastboot or recovery, screen doesn't turn on and no charging screen when connected to power.
So I had to open up the back cover and did the "two point short" trick to force boot it to EDL mode, where I was able to flash the factory (earlier) fastboot image (Nougat) through Miflasher program.
After that I was able to boot to fastboot, and its default recovery. But the problem remains, I cannot boot to the system itself. When I press the power button it shows the splash screen and says "The system has been destroyed". I can go to fastboot with volume down + power button combo. I tried to flash the same fastboot rom through fastboot as well, I got the same result.
I also flashed the official and unofficial TWRPs on it, it boots into them as well. I also tried to flash other custom ROMs in it through those TWRPs, following every step clearly, where they say that after flashing the ROM TWRP needs to be flashed again. I did all that. But the problem remains, after the flash and reboot it always shows me that "The system has been destroyed" message and the phone has to be shut down (because it asks you to power it off on that message.)
And ofc the phone is unlocked. Although it is easy for it to be locked and unlocked through fastboot anyway.
So I am basically stuck now. Do you know a way forward? Is there a cure for it? Or my last option is to take it to service center when I know for sure that they are going to ask me to change the motherboard. This device was bought in Hong Kong so the warranty card is useless here.
Thanks for reading.
And I also made a thread about it, needs to be updated with this.

Bricked REDMI 3S with locked bootloader

I have a bricked redmi 3s prime. It is having locked bootloader.
First I had search for local repair center to fix it. But the shop guy said me to replace motherboard of device. But I'm not sure what is the exact issue with device, because I can still use recovery option as well fastboot.
I'm bit technical, so I thought it is software issue. So I thought to un-brick it myself. So I had tried almost many methods to un-brick it but not getting any success till yet.
The methods I have tried mentioned below.
1) From recovery, simply wipe data storage and try to turn on device. Waited for 20 mins on mi logo screen. No Success.?
2) Enter into fastboot mode (Device detected as some random string on PC) and simply try to flash both fastboot roms (Global and Developer) using MiFlash beta Tool. Even fastboot mode unable to flash those official roms. No Success.?
3) Enter into EDL mode using TestPoint method (Device detected as COM6 on PC). Again try with both roms MiFlash. After flashing each rom I had waited over 30 mins on MI logo screen, but nothing happens. No Success.?
One thing common while trying all above methods is that battery power less than 10%. I can not full charge device, because there is no way to turn off device if I'm not succeed with my steps.
So is there anything I'm still missing? Can someone help me with this?

The system has been destroyed, lock bootloader

Hi!
I have a problem with an M2 that I am trying to recover. I don't know what exactly happened, but who gave it to me said they found it one morning stuck with the MIUI logo, and then turn it off and on again finding this error ... I'm afraid that the update process was interrupted, but usually the phone not start updating without asking.
The phone only goes in Fastboot, no recovery, has the bootloader locked and unfortunately an associated MI account was not made.
I have tried everything I found online, but I have not succeeded to flash on it anything or unlocking the bootloader.
If I use the command fastboot devices it is recognized, same in Mi Flash, but having the bootloader locked it does not flash anything.
I was unable to put it in EDL mode, as some advised.
Is there anything I can do or the only way is to take it to a service center?
Thanks for your help
Oh sorry, I think I got the wrong section by mistake.
If it was to be put in POCO M3 Questions & Answers I kindly ask if you can move it, thanks

This miui version can't be installed on this device (K20 with locked bootloader)

Hello. I need help!
I have a K20 and I made the mistake of locking the bootloader with the MI 9T room.
The cell phone does not turn on because it says "This miui version can't be installed on this device". So I have no way to unlock the bootloader by the traditional method that needs the cell phone on.
the only way that it authorizes the installation of a room is through recovery, but my pc sees my cell phone as an MI 9T and it only lets me install its room, since this room doesn't boot.
I also tried in MI Flash through edl mode and it says I don't have an authenticated account. I have no idea what I can do anymore.
I would be very grateful if someone could give an idea of something.
I'm new to the forum, sorry if I wasn't so clear or if I posted in the wrong place.
