bootloop, locked bootloader, flashing with testpoint doesn't work - Xiaomi Mi A2 / 6X Questions & Answers

Hello guys,
like many other people my Xiaomi A2 phone don't want to boot anymore. Everytime i tryied to start, it got stuck at Android One screen an reboots. I've tried every powerbutton/vol-button combination i could found but nothing worked, only fastboot mode was possible. I red very much here and in other forums. Because my bootloader is locked, I opened my phone to flash it with the testpoint method. I tried different versions of the mi-flash-tool between 2015 and 2018 and also tried various rom versions between V9.6.13 and V10.0.13 but nothing worked. Mostly the process fails with the Error "ACK Count don't match". Especially with newer versions of the mi flash tool.
I have the global version of the phone and never flashed any other rom before the phone got bricked.
The drivers I use are from the mi community forum (can't post link because i'm new. Title is: [All in One] MIUI Flashing Guide: Unbrick, EDL Method / Locked Bootloader, Unlock Bootloader, More)
I also tried different USB Ports.
It would be really great if you could help me with any other idea or tip!

where you from? do you have telegram? i was in dsame situation last night but i manage to make it work doing testpoint method.

Go Service Center Your Problem Solve Because I Face Same Problem And Know I Save My Mi A2 Life

Hello. Did you manage to solve the problem?
I have the same situation.

I don't know if this is the same situation as you guys, but I managed to successfully flash my MI 6x with wayne v 10.3. Even then the phone always starts in a bootloop. I'm beginning to suspect this is a hardware problem.

I faced a similar issue. Have you managed to solve it? I also have the same error and can't flash "ack count don't match"

Bootloader re-locked

Hi everyone, some weeks ago I converted my A2 in 6X because I wanted to test MIUI. Yesterday, dealing with an update my phone get into a bootloop. Well, I used MiFlash to fix it but I selected "flash and lock" (yes, I know, I'm stupid).
The main thing is that I'm in a Chinese ROM with lock bootloader and when I try to unlock it I get error 86023.
I dont know what to do. I've thought about test point to flash Xiaomi.eu but I'm not sure bcause the bootloader is locked.
Someone with a posibble solution? Thanks
Welcome to the Club
Same thing happened to me.
You can now choose between China Developer or Stable.
I tried many progs and tutorials to unlock the bootloader but no way.
If you need GooglePlayStore, CalenderSync and ContactsSync:

I'm now on stable V10.3.6.0.PDCCNXM and all is working quite well.

It didn't happened to me for myself, but I just asked this question to get better knowledge about bootloader stuffs:
As I understood the current problem is this:
You need to unlock your bootloader again, there is just (as much as I know) 2 ways to approach, which both of them will not help you:
1. Unlocking as a A2 : but your device is not a A2 anymore, so the device will not be unlocked by this method.
2. Unlocking as a 6x : but this one won't be successful either since the dedicated unlocking program asks for a real 6X device with a registered IMEI number by factory, which in your case is NOT.
So, you will be left just with the options that need no Unlocked Bootloader, as mentioned above, like Chinese Stable versions. ( That in my opinion it does NOT sound awful. )
(BTW, every day comes with new procedures, maybe you can find a new method to unlocked the bootloader again, there was times that many expertise told, after stucking in ARB4 trap, you just need to find a suitable Trash for your device!, but now we all know that there is plenty new ways to deal with it).

not the imei, it asks for 6x serial number which device is a2. you have to find someone who has authorized mi account to unlock this device. it is only way for now

Authorized Customer Services, or a friend who works there
It is very possible that they can restore your phone (and as well your bootloader) as what it was in factory.

Yes, exactly.
Hello my friends, i managed to unlock the bootloader of my converted A2/6X.
I tried several times to switch from stable china to developer china but from 9.8.15 to 9.9.3 no one worked.
After installing one of the developer roms, the phone only shows the boot screen for 2 seconds and turns off, with charger it boots endlessly or shows the green battery symbol after some minutes.
One thing that works, is using a rubber band to fix "Vol+" and connect phone via usb or charger, mostly after 5-10 minutes it will enter the "Miui-Recovery", then you can start "Mi-Assistent" in the "Miui-Recovery" and flash back the stable china, so luckily no need of EDL.
After flashing the last 9.9.3 rom and the phone was all screwed up, again. I tried the original "miflash_unlock-en-2.2.624.14" and it worked.
I have done this "thousand" times before with all available unlock tools I found but never succeeded before.
Download: miflash_unlock-en-2.2.624.14
https://xiaomifirmware.com/downloads/download-mi-unlock-2-2-624-14-windows/
https://androidfilehost.com/?fid=889764386195916630
Now I tried to boot into recovery “fastboot boot twrp_wayne.img” but it didn't work, because the phone reboots or turns off after 2 seconds.
So I flashed the china stable via fastboot (worked), let it boot up, no setup, reboot to enter fastboot and flashed successful the orangefox-twrp.
Hope somebody can also unlock his bootloader or maybe it was just luck.

Unbrick Redmi 8

My phone suddenly get stucked into Redmi boot logo, cannot access system recovery but can access fastboot menu.
The problem is I hadn't enabled OEM unlock and developer options before. All the methods that I found so far requires bootloader unlock for that I also don't have MI account . What might be my next move? Thank you.
its hard to say what we can|t do with a still locked bootloader. if going to an authorized service center is out of reach, all we can do is try i guess. id still suggest going there if you can easily access your google account.
there are a few threads that say we can flash a still locked bl, but im not so sure.

Xiaomi Firmware Updater

With EDL mode? I'm in a similar situation, a friend's mother forced a shutdown during a firmware update and destroyed the system that way. Of course the bootloader is blocked. I find it extremely stupid of Xiaomi to rely on a working system to give you the chance to unlock the bootoader but I guess that's how you sell some extra phones.
So far I've taken out the rear cover and the plastic that goes on top of the motherboard, unplugged the battery and with an arduino cable and some fiddeling shorted the "boot" pins while connecting the USB cable. Seems to be working given that MiFlash has changed the locked bootloader error for "indice fuera de limites" or in English "index out of limits error". I guess I don't have the right ROM so I'm downloading another one, but I'm struggilng to find the correct original fastboot ROM. The first one I've downloaded from Mi Community, the second one is from xiaomifirmwareupdater, but is gonna take forever to download. And I mean... F-O-R-E-V-E-R

gl with that, as only authorized people can properly flash from there. while i havent used EDL, there are some trusty people who can help us out (ive seen it in tg groups)
a site did say maybe using another version can help, who knows it might do the trick

Question Redmi note 10 Pro not flashing, not booting

Long story short, my gf Redmi Note 10 Pro somehow got to MIUI Recovery menu and 3rd party service managed to erase recovery and everything from the phone and gave back the fresh looking brick stuck on Fastboot!!!
I have successfully flashed EEU Sweet ROM (Europe (EEA) latest Fastboot ROM MIUI V12.5.6.0.RKFEUXM) on the Global version though and after that it comes to recovery menu but it shows in red "NV data is corrupted" now I am clueless what to do next. Desperate me tried to flash Global latest Fastboot ROM MIUI V12.5.9.0.RKFMIXM but it gives Anti Rollback error so based on info here https://www.xda-developers.com/xiao...78.2028059671.1642858063-854958160.1642858063 I have checked the Anti_version.txt of the current ROM and the one I try to install and both is on 3 so based on the info I should be able to flash to the same number but it wasn't successful so I tried to edit Flash_all.Bat file and remove the ARB check commands but even after that I still get the ABR error. What should I do? Am I taking a wrong path in solving the issue? Would flashing it again solve the "NV data is corrupted" issue?
I dunno if this helps, but I was stuck in Fastboot as well at some time. Nothing helped, not even flashing through fastboot. The only tool that helped me was the Xiaomi Tool V2 https://www.xiaomitool.com/V2/ here. No ad or something but this really helped alot without problems.
Other possible problem by another user: https://forum.xda-developers.com/t/redmi-note-10-pro-sweet-nv-is-corrupted-fixed.4345659/
Maybe you installed the wrong rom?

Thanks, DLin the tool you mentioned atm but yes I did dl a EU version on global which I read it is no issue as long as it is not on Chinese version. It all started suddenly, out of nowhere the phone rebooted on Fastboot so it was taken to a 3rd party service and their they tried to fix it by wiping the phone to an unrecoverable state and said this is a new model so the files are not yet published you better take it to an authorized service!!!Oh I am mad! I'll report after trying the tool. Btw the other solution you mentioned was the 1st thing I tried but the file in 1st step is removed from the hosting server and someone asked the thread creator to reupload but no reply yet :/

Ok so now I tried with the tool and interestingly I had to make choices which were not easy and obvious anyhow, it didn't work
It gives the below error and seems to be called "sideload" status issue. But the phone now still reboots on Main Menu with the same old "NV data is corrupted"

Redmi 9 (lancelot) MTK Bricked

Hey.
I've been rooting some previous android phones and I am confortable with that.
In xiaomi I really wanted to do it because MIUI has a battery optimizer that keeps shutting down some apps.
I've managed to unlock the bootloader but when I tried to flash something through TWRP it got stuck in bootloop.I can't access EDL.
Is there anyone who could help me ?
Been trying to follow some DIY but nothing worked.
This is a company phone, any help would be highly appreciated

Question Xiaomi Mi11 Bricked (black screen-EDL Mode)

Hello everyone! I think i messed up so i need your help!
I was using a xiaomi.eu rom and i decided to try the PixelExperience. After i successfully flashing my phone i decided that pixel rom is not for me so i wanted to flash to my previous rom. After many unsuccessful flashing attempts i managed to brick my phone. My phone doesn't turn on, the screen is black although in "device manager" it shows Qualcomm HS-USB QDLoader 9008 so i guess it is on EDL mode. When i try to flash stock rom with MiFlash i get an error "write time-out, maybe device was disconnected". Any ideas?
Happened to me too when I tried going to another aosp based rom. In the process of you doing so you must have made a slight error which through you into that mess. For me to get out of the situation your in right now you'll need the official login for mi tool which nobody but people in xiaomi have. And the reason its not made for the public is due to security reasons. But anyways besides the point you'll probably need to contact someone online and they'll login in and flash the eu rom you want. It cost me 25 euro in order to do this. Wish you luck!
https://forum.xda-developers.com/t/...ring-firmware-for-venus-xiaomi-mi-11.4288933/ you could try this, on xiaomi.eu forum said it doesn't need authorization to flash via Xiaomi Flash Tool. If it doesn't work you'll need to disassembly your phone. I crashed my back glass coz of that :/
