Download Xiaomi Mi A2/A2 Lite February 2021 Security Update (OTA and Fastboot)

Download and Install Xiaomi Mi A2 Android 10 Update

Through this page, you can download the latest February 2021 security update for Xiaomi Mi A2/A2 Lite, along with all the previous updates. Further, we will show you how to manually update the Mi A2/A2 Lite by flashing the fastboot ROM or by installing the recovery OTA package using stock recovery/TWRP.

Xiaomi’s Mi A2 and Mi A2 Lite came with Android Oreo at the time of its launch and received the Android Pie update last year, which was followed by the Android 10 update earlier this year. Since then, the manufacturer has consistently been rolling out Android 10-based monthly security updates for both phones every month.

That being said, the latest February 2021 security update is now available and comes with “V11.0.21.0.QDIMIXM” and “V11.0.18.0.QDLMIXM” build numbers for the Mi A2 and Mi A2 Lite, respectively. To force-check for the OTA update, you can go to ‘Settings’ → ‘System’ → ‘System update’ on your phone.

Since the rollout will take place in stages, it may take time before it’s available for every user. If you’re eager on updating now, then you can download the Android 10 Fastboot Image or Full OTA zip package for your Xiaomi Mi A2/A2 Lite from below, and follow the instructions to install it manually. But before you get there, take a quick look at what new features this update brings to your phone.

Prerequisites

Make sure that you fulfill all the requirements listed below before you head to the download links and instructions.

  • Take a backup first! Manually installing updates on your phone may sometimes lead to data loss (if done wrong). It’s always a good idea to keep a complete backup of all your important data and safeguard it. You can also follow our guide on how to take a backup of your Android device.
  • Charge your Xiaomi Mi A2 device to a sufficient battery level. This will help prevent any sudden shutdowns during the update process.
  • For Method 1 only:
    • Download the Android SDK platform-tools package and install it on your PC.
    • Install the latest Xiaomi USB drivers on your PC.
    • When asked to launch the command-line window on the PC, do the following.
      • PowerShell in Windows: Open the folder where ADB and fastboot are installed (e.g. C:\plaftorm-tools). Then hold the SHIFT key and right-click on an empty space inside the folder. Finally, select the “Open PowerShell window here” option.
      • Terminal in macOS/Linux: Launch the Terminal window and use the “cd” command to change its directory to the folder where ADB and fastboot are installed. For example, if you installed it to /Documents/platform-tools, then you should use the following command to change the directory:
        cd Documents/platform-tools

Download Xiaomi Mi A2/A2 Lite February 2021 Security Update

Firmware files for Xiaomi Mi A2/Mi A2 Lite are available as a fastboot ROM and recovery ROM (OTA package). The former can be used to install the update on any unrooted or rooted Mi A2 device using the fastboot tool. The latter can be installed via the stock recovery or a custom recovery such as TWRP.

Make sure that you download the firmware file according to the installation method you choose.

Important note regarding Mi A2’s October update:

As reported by several users over at XDA, flashing the V11.0.15.0 fastboot ROM will force the phone into stock recovery and show the “Can’t load Android system. Your data may be corrupt.” message. This will require you to perform a factory reset in order to boot the phone.

So, if you’re going to upgrade this way, make sure that you take a full backup of all your data beforehand so that you can restore it after updating. This issue doesn’t seem to affect the November security update (and above).

How to Manually Install Updates on Xiaomi Mi A2/A2 Lite

Installing the latest update on your Xiaomi Mi A2/Mi A2 Lite is easy and can be done in three different ways/methods. These are:

  • By sideloading the Recovery ROM (OTA) in stock recovery. Suitable for devices with a locked bootloader.
  • By flashing the Recovery ROM (OTA) through TWRP recovery, while retaining both TWRP and Magisk root after the update.
  • By flashing the fastboot ROM, suitable for restoring stock firmware, or making a fresh install. Requires an unlocked bootloader.

So, you will have to choose the method depending on whether or not your phone’s bootloader is unlocked and further if it has a custom recovery installed, or not. For an average user, who hasn’t modified their Mi A2 in any manner, Method 1 (sideloading the OTA) is recommended.

Method 1: Sideloading OTA in Stock Recovery

Earlier, there was no possible way to manually upgrade Mi A2 with a locked bootloader. However, things have changed now. Starting with Android 10, the Xiaomi Mi A2 and Mi A2 Lite support OTA sideloading/installation via stock recovery. This means you can now sideload the update’s OTA ZIP package through the stock recovery menu.

To do this, download the OTA package (recovery ROM) of the update you want to install and boot your Mi A2 device into stock recovery mode. Then follow the instructions on this guide to sideload the OTA ZIP package.

Method 2: Flashing Recovery ROM via TWRP Recovery

Note: Flashing the full OTA package will unroot your phone, replace TWRP with stock recovery, and encrypt your device. To maintain all these things, you will need to follow some additional instructions after flashing the OTA, as listed below. This will also erase all your data, so take a backup first!

  1. Download the latest recovery ROM package for your Mi A2/Mi A2 Lite
  2. Also, download the Magisk, TWRP installer, and Encryption Disabler zip files:
  3. Copy the downloaded files to the phone’s internal storage.
  4. Power off your phone completely and boot it into TWRP Recovery Mode by holding the Volume Up and Power buttons together.
  5. (Optional): If you’re using a custom ROM, go to ‘Wipe’ -> ‘Advanced Wipe’ and wipe the ‘Cache’, ‘Dalvik/ART Cache’, ‘Data’ and ‘System’ partitions. In case you’re using stock firmware with TWRP and root, then you can skip this step.
  6. Go to the ‘Install’ menu in TWRP recovery and select the Recovery ROM file (e.g. miui_DAISYGlobal_V11.0.12.0.QDLMIXM_1e8d0d76bb_10.0.zip).
    Install Xiaomi Mi A2 Android 10 OTA Update Package using TWRP
  7. Swipe the button on the screen to flash the recovery ROM on Xiaomi Mi A2/A2 Lite.
  8. Important: Now, change your phone’s currently active slot to the currently inactive slot. To do this, go to the ‘Reboot’ menu in TWRP and check the currently active slot. If it’s “a”, then set it to “b”, or vice-versa.
    Switch from active slot to inactive slot in TWRP on Mi A2
  9. Once you have successfully switched the slot, tap on the ‘Recovery’ button in the ‘Reboot’ menu to reboot your Mi A2 into TWRP recovery.
  10. Now, go to the ‘Install’ menu and select the Forced-Encryption Disabler zip file (e.g. Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip).
    Install Forced-Encryption Disabler on Xiaomi Mi A2
  11. Tap on the ‘Add more ZIPs’ button and select the TWRP installer zip file (e.g. twrp-installer-3.3.1-dees_troy-daisy.zip).
  12. Press ‘Add more Zips’ again and select the Magisk zip file (Magisk-v21.x.zip) to add it to the flashing queue.
    Flash Magisk to Root Xiaomi Mi A2 on Android 10
  13. Finally, swipe the button on the screen to flash the files.
  14. Once you have successfully flashed the files, tap on the ‘Reboot System’ button.

Method 3: By Flashing Fastboot ROM

  1. Download the latest Fastboot ROM for your Xiaomi Mi A2 or Mi A2 Lite.
  2. Extracted the downloaded ZIP file to an easily accessible location on your PC to get the TAR file. You will further need to extract the TAR to finally get the firmware images and flash scripts.
    Extract Mi A2/A2 Lite Android 10 Fastboot ROM on PC
  3. Move all these files to the folder on the PC where the Android SDK platform-tools are installed (Example: “C:\platform-tools”).
    Move Mi A2/A2 Lite Fastboot ROM Files to 'platform-tools' folder
  4. Hold the SHIFT key of your keyboard and right-click on any empty space inside the folder.
  5. Select the ‘Open PowerShell window here’ option from the contextual menu that appears on the screen.
  6. Now, power off your Xiaomi Mi A2/A2 Lite completely and boot it into Fastboot Mode by holding the Volume Down and Power keys together.Boot Xiaomi Mi A2 into Fastboot Mode
  7. Connect the phone to the PC using the USB cable.
  8. Now, there are three different types of flash scripts available, which are as follows:
    • flash_all.bat: This will flash the stock firmware and erase the internal storage
    • flash_all_except_data_storage.bat: This will flash the stock firmware while preserving the data on the internal storage
    • flash_all_lock.bat: This will flash the stock firmware, erase the internal storage, and relock the phone’s bootloader
  9. Simply double-click on the desired flash script to flash the Latest fastboot ROM on your Mi A2/A2 Lite.

If you see a message (Invalid sparse file format at header magic) while flashing the files, do not worry, it’s completely normal. The message is a part of the regular flashing process.

The flashing process could take a few minutes to complete and the progress will be shown in the command-line window. During this time, make sure that you do not disconnect the phone from the PC or disturb the USB connection.

Your Xiaomi Mi A2/Mi A2 Lite should now be running the latest Android 10 firmware with the February 2021 security patch. If you have any questions regarding this update or the instructions in this post, please feel free to post a comment below.

Enjoy your updated phone now!

  1. Hi,

    thanks for the nice article.

    I am trying to install the
    miui_JASMINEGlobal_V11.0.14.0.QDIMIXM_6e562068f2_10.0.zip
    update with
    adb sideload
    but I get this error, after the verification:

    “`
    E: error in /sideload/package.zip (status 1)

    Installation aborted
    “`

    Thanks for your help

    1. Which firmware (build number) is your phone currently running? Is it based on Android Pie or one of the initial Android 10 releases?

  2. Hello,

    I want to update mi a2 lite from 10.0.10 to 10.0.20 (latest Pie).
    Have unlocked bootloader and root with magisk.
    What is best method to update while keeping apps, settings and unlocked bootloader?
    Should i choose fastboot image with miflash and option save user data with package here https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
    OR will it be better to download full recovery package here https://xiaomifirmwareupdater.com/archive/miui/daisy/ and then flash it with recovery method (rename to update.zip?)

    Also in the future when android 10 package is stable, what will be best method then?

    1. Mark, the recovery method would not work because (1) The stock recovery on Android Pie doesn’t allow sideloading, especially not with root, and (2) You do not have a custom recovery to flash the recovery ROM.

      So, you’re left with using the fastboot ROM, which is totally fine.

      I assume the OTA update that has arrived on your phone (Settings > System > System update) is of Android 10, and you do not wish to install A10, do you? And that’s why you wish to opt for manually upgrading the phone?

    2. Hi Dhananjay,

      Interesting, because f.e. here are instructions that it should also work with recovery method (zip on sdcard or sideloading with default recovery)?
      https://forum.xda-developers.com/mi-a2-lite/how-to/how-to-manual-update-v11-0-4-0-users-t4082815

      Fastboot is totally fine you say, so that means i will keep my apps, settings and unlocked bootloader while updating?

      2 reasons. Indeed do not want android 10 yet, so want to go to latest pie version. And second reason is i can not use OTA anymore it seems, because when manually checking for system updates it always says i’m up to date.

    3. Hi again, Mark. Like I said, “the stock recovery on Android Pie” doesn’t allow sideloading. It only works on Android 10 and later. Somehow, Xiaomi managed to screw up that sideloading option since the Mi A1 (still not fixed on that), all the way through the Mi A2 series and Mi A3 as well. For both the latter, they fixed it starting from the Android 10 update. The instructions you’re referring to instruct upgrading from a previous Android 10 firmware (V11.0.2.0; where sideloading works) to a newer one.

      Yes, it will work without any hiccups. Just make sure to take a backup first for safeguarding your data. And select the “Save user data” option in the Mi Flash Tool. Any other option would erase the device, and/or relock the bootloader.

      Okay. So flashing via Fastboot will probably fix the OTA update problem as well. Once that’s fixed, it’s easy to install OTA updates with Magisk. See here.

    4. Hi Dhananjay,

      Thank you again for your answers.
      It is clear i will use the fastboot method.

      Last question(s):
      So when i want to upgrade to 10 specific version from 9 it will still be fastboot method? Or does OTA (when working again) give me option to which version i want to upgrade (suppose it will only offer latest)?

      And when on 10 already, and as such recovery also works, what will be recommended way, still fastboot or recovery?

    5. Yes, upgrading from A9 to A10 will be done through Fastboot. Exactly the same way that you’re doing it now.

      The OTA will generally take you to the latest version available.

      It doesn’t matter if you’re on Android 10/Android 9 (with Magisk root) when updating the the “latest” OTA version available. You could simply use the instructions in the tutorial I linked in the previous comment.

      However, if you’re on Android 10 (and unrooted), then recovery installation is the way to go. The XDA thread you linked followed the same instructions as on this page.

      To sum up, there are quite a lot of factors that pop in when it comes to updating a rooted phone. Depends on your setup (is it just rooted or rooted along with TWRP) and if you wish to upgrade to the latest or to a specific firmware version. And then in case of the Mi A2 series, the fact that the recovery sideload method doesn’t work on Android Pie (and below) weighs in as well.

  3. Hi Dhananjay,

    My device is working perfectly after installing gcam.. thank you ao much….
    &
    Is there any update… To use both stock camera and Google cam.

    1. Karthik, for now these are the recommended ports. As newer versions are available, we will be updating this page.

  4. I’ve downloaded and extracted the platform tools and stock rom and placed it in the c\ platform tools as per your instructions but didn’t find any files with
    ” .bat ” extension.

    1. Prithwish, could you please share the exact name of the file you downloaded?

  5. error: fastboot flash bluetooth_a bluetooth.img
    and i tried this “fastboot flashing unlock_critical”
    still cannot unlock

    1. PS D:\xiaomi\newflash\platform-tools> fastboot flashing unlock_critical

      FAILED (remote: Flashing Unlock is not allowed

    2. Hi Von. Before you can unlock, it’s imperative to enable the OEM unlock toggle within Developer Options. Instructions for the same could be found here.

      Once you have done that, reboot your phone into Fastboot Mode, connect it to the PC via USB and then:
      1) Issue: fastboot flashing unlock
      2) Reboot back into Fastboot
      3) Issue: fastboot flashing unlock_critical

      Once you have the bootloader unlocked, you can flash the Fastboot ROM.

  6. Hey Dhananjay, I have been following this thread for quite a long time, I am wondering is is there any method I could use without losing my data intact and keep my phone is rooted . I don’t want to re-root or reinstalling my applications again.
    please help.

  7. Hello, I am using Mi A2 from India. Bootloader is unlocked.
    After getting it flashed from service center as per instruction of Mi software developers,the phone started to misbehave. Often it gets freezed, randomly apps are crashing, some apps are not even opening saying that it’s a custom rom and rooted. Speaker stops working. Sometimes hotspot and Bluetooth stops functioning. After rebooting things get back to normal. And it’s happening too often.
    Till now didn’t get any OTA update. Last security patch is of January,2020. What hell is happening!

    Build number showing
    jasmine-userdebug 10 QKQ 1190910002 V11.0.5.0.QDIMIXM test-keys

    Please tell me how to get it fix and can I flash the downloaded file from your website miui_JASMINEGlobal_V11.0.5.0.QDIMIXM_e2c5e49de6_10.0.zip through Mi flashinf tool?

    Please help.

    1. Hi Souvik. It feels like a bad flash to me. Anyhow, try flashing the latest V11.0.10.0 fastboot ROM from above to check if it makes a difference. Just extract the fastboot ROM on your PC, connect the phone to the PC in Fastboot Mode, and run the ‘flash_all_except_storage.bat’ file.

      Or if you’re familiar with the Mi Flash tool already, then you can use that as well.

  8. Hi friend
    I am trying to update me phone mi a2 lite via fastboot
    I don’t see the command flash all except data in the folder.
    What is wrong?

    1. Hi Dhananjay,

      My mi a2 current version is V11.0.8.0.QDIMIXM (April 2020 Security Patch)

      and now should i download this version ?: V11.0.10.0.QDIMIXM (May 2020 Security Patch)

      and install it..?

    2. Yes, Karthik. That’s the version you need to install. It’s the same update that you’re currently getting on your phone.

  9. My brand new mi a2 running stock android oreo won’t install ota update. My device is not rooted. It’s downloading November 2018 security update which is 416 mb but during installation stage it says couldn’t update installation problem. I tried factory reset, with and without sim card by WiFi but it won’t install. I have verified my imei it says it’s genuine mi a2 4/64 gb international version. This is my firmware OPM1.171019.011/V9.6.5.0.ODIMIFE
    I don’t have computer. Will it install official pie ota zip package by stock recovery mode

    1. Hello Balachandar. The OTA zip file can only be sideloaded via stock recovery if you have Android 10 firmware installed. The stock recovery on older Android versions like Android Pie or Android Oreo doesn’t support sideloading of OTA zips.

      I believe it’s best that you download the fastboot ROM and flash it via fastboot using a computer. This will not only update your phone to the latest firmware but will also allow you receive future OTA updates and install them without any problems.

      If you need help flashing, please let me know. You can also get it touch with us via our Facebook page.

  10. these are the lines showed in the black colored cmd when i click on the ”flash_all_except_data.bat” file

    C:\platform-tools>fastboot getvar product 2>&1 | findstr /r /c:”^product: *daisy” ||
    product: daisy

    C:\platform-tools>set CURRENT_ANTI_VER=1

    C:\platform-tools>(set version=1 )

    C:\platform-tools>if [1] EQU [] set version=0

    C:\platform-tools>if 1 GTR 1 (

    Erasing ‘boot_a’ FAILED (remote: ‘device is locked. Cannot erase’)
    fastboot: error: Command failed
    “Erase boot_a error”

    1. Hi Hamid. The error states that the phone’s bootloader is locked.

      In order to flash the fastboot ROM, you’d first need to unlock the phone’s bootloader. Could you please tell me which software version is currently installed on your phone? Go to ‘Settings’ > ‘About phone’ and let me know the information shown under the ‘Build number’ section.

    2. Oh. So in that case you will first need to unlock the bootloader of your phone and then flash the Android 10 firmware via Fastboot.

  11. dear dahananjay

    i double clicked the ”flash_all_except_data.bat”, the black colored cmd window popped up and wrote some commands for less than a second and then vanished, every time i click it its the same,pops up for a second and then nothing. what should i do?

    1. Hi again, Hamid. I have replied to your other comment. Please read it and provide me the required information.

  12. hi there
    i was flashing android 10 to my mi a2 lite using method 1, everything was fine right till the first sentence of the command, it replied ”fastboot: error: cannot load ‘bluetooth.img’: No such file or directory”
    i looked in the image fie of mi a2 lite(daisy_global_images_V11.0.4.0.QDLMIXM_20200404.0000.00_10.0_88297a8e92.tgz) and there was no such file as bluetooth, what shoud i do?
    are these the commands of only mi a2? then what are the commands for mi a2 lite?

    1. Hi Hamid. There’s no need to execute the commands anymore. I am yet to update the instructions.

      Once you have downloaded and extracted the fastboot ROM, you will find an “images” folder as well as some flashing scripts and other binaries. At this point, just connect the phone to the PC over fastboot mode and just launch the ‘flash_all_except_data.bat’ file on your PC (double-click it).

      The file is basically a flashing script, that flashes the firmware automatically for you. This script is included within all the official and most unofficial fastboot ROMs.

  13. hi there friend i repetead the process and everything went right this time around! thanks so much ^^

    1. Hi Andres. It’s good to know that it worked out alright! You’re welcome.

    1. Hi. I believe you are referring to the V10.0.20.0 update based on Pie, right?

      If so, then you can get the V10.0.20.0 fastboot ROM from this link and recovery ROM from this one.

  14. also another question, how much time should pass after the final step is done till the phone boots up and logs in succesfully?

  15. Hi there friend!

    i have a lil problem you see, i have the xiaomi A2 and did the method 1 all step by step and everything was succesfully done, However after all the steps are done and the phone reboot, it got stuck on the androidone white page , i dont see it opening the android or anything , it just there. Any help? the most i have let it be in that state is 25 minutes after shutting it down myself , should i try everything again?

    1. Hi Andres. Did you use the following file? – “V11.0.8.0.QDIMIXM-Unofficial.rar”

      If so, then please boot your phone back into fastboot mode and connect it to the PC. Then extract the fasboot ROM (.rar file) on your PC and double-click on the extracted “flash_all_except_data.bat” file.

      This will launch the flash script and will flash the firmware on your phone automatically. So, you will not need to execute any commands manually. Once the flashing finishes, your phone will automatically boot into the OS.

      One more thing, it’s the regular Mi A2 OR the Mi A2 Lite?

  16. Por ejemplo si instale una ROM stock por twrp pero me da error al recibir actualizaciones OTA, y quiero que mi celular vuelva a estar como antes, puedo realizar el método 1? Y ya mi celular estaría como antes? Tengo el Xiaomi mi a2 y la versión 11.0.4 parche de diciembre

    Soy el mismo del anterior comentario solo que me equivoqué en una palabra al mandar el comentario

    1. Hi Roger. Yes, you will need to flash the fastboot ROM to get your phone to its original state. Could you please confirm if it’s the Mi A2 or the Mi A2 Lite?

    2. Bueno mi celular es el xiaomi mi a2 normal, pero por ejemplo puedo descargar la ROM de arranque rapido y utilizar la herramienta mi flash para poder instalarla, si se podra realizar?

    3. In that case, simply download the fastboot ROM from here: https://drive.google.com/file/d/1S2YeeBMiJhkk5lWAEua1UvcQaR-xHUvb/view

      Extract the downloaded file. The extracted files will include a script called “flash_all_except_storage.bat” (or something similar).

      Simply connect the phone (in Fastboot Mode) to the PC via the USB and double-click that ‘flash_all_except_storage.bat” file. You will then see a black colored CMD window on the PC showing the flashing process. Once it is finished, your phone will automatically reboot into the system (OS).

    4. “Formato de archivo disperso no válido en el encabezado magico” eso es lo que me aparecio al terminar el ‘flash_all_except_storage.bat ” y ahora que debo hacer?

    5. There’s nothing to worry about that message while flashing. Let the flashing complete and then the phone will automatically reboot.

    6. Amigo muchas gracias ya pude instalar la actualización, gracias por tu ayuda

  17. Hey Dhananjay. Just a suggestion, just like your other thread on this website, should put remark on “Invalid sparse file format at header magic” message. I initially thought it abnormal and was a failure flashing using the included script.

    1. Hi Azman, thank you for the suggestion. I have added this to the ‘Notes’ box just above the Method 1 instructions.

    1. Hi Vishnu. You wouldn’t need the tool to flash it. You can simply use the included ‘flash_all_except_storage.bat’ file to flash the ROM.

    2. I have flash this using mi flash tool. Using the latest unofficial fastboot rom. I still cannot install the latest OTA update. 🙁

    3. The V11.0.6.0.QDIMIXM-Unofficial.rar version. I was getting update notification, but after downloading the latest OTA, still fail to update.

    4. The error means that there’s still some modification leftover on the corresponding slot. Please use the latest fastboot image and use the included flashing script (flash_all_excapt_data.bat) to flash the update.

  18. I see you moderated away my comment on the danger of flashing both A and B slots at the same time, defeating the purpose of having the slots — a failsafe fallback if the update is bad.

    I recommend instead to check which side is active (fastboot getvar current-slot). If A is active then flash B or if B is active then flash A. After flashing you make the flashed side the active one (fastboot –set-active=X where X is a or b) before rebooting.

  19. Flashing both A and B sides in step 10 defeats the purpose of having two sides: an option to revert if something is wrong with the update. Like the case now with the A2 Lite update which is causing a lot of phones to die, including mine. Luckily I just tried the update using the normal OTA method so I could revert back to Android 9 quickly.

    1. Hi Zaki. That was a very clear observation on your end. I just discovered the issue that the Mi A2 Lite users are facing with this update.

      I will modify the above commands accordingly.

    2. Thanks. Just one correction: I believe the syntax for changing active slot is as I wrote it:

      fastboot –set-active=X

      (where X is a or b). This is the command I used yesterday to recover from the failed Android 10 upgrade.
      I am not sure it will work with set_active.

    3. Hi Zaki, both the syntaxes are correct. The one I mentioned is shorter and much easier to memorize, so I added that instead. Again, thanks a lot for your observation and suggestions.

  20. The title of this page is “https://www.thecustomdroid.com/xiaomi-mi-a2-lite-android-10-update”.

    Note – Please pay particular attention to “Xiaomi-MI-A2-lite”.

    Then super Dhananjay phone guy mentions somewhere towards the bottom of the thread, after you’ve quite possibly f*cked your phone up sideways:

    “Hi Amirul. According to a recent report, Mi A2 Lite running Android 10 was spotted on Geekbench. So the update might roll out soon!”

    So… in brief. If you were ACTUALLY wanting to update an A2 Lite, you quite possibly now have a bricked A2 Lite or something like an A2 (not lite) running some crazy MuMi? interface.

    I’m guessing, because I wouldn’t attempt this nonsense from a guy who apparently cant distinguish between an A2 and an A2 Lite.

    1. Hi Rasco. Thanks for the feedback.

      Yes, the URL contains the ‘Lite’ moniker. I chose to add it because I ASSUMED that Xiaomi would release the Android 10 update for the Mi A2 Lite very soon. So, I could just update the title of this post (when they release), along with the download links for the Mi A2 Lite too, because the instructions to install it would be the same.

      Thought that just creating another similar post with nothing different than the download links would not be a good idea.

      Within the article itself, I don’t think I have anywhere mentioned the Mi A2 Lite, and neither in the title.

      I will make sure to mention it to the very top explicitly stating that the Android 10 update for the A2 Lite has not been released yet. So that no one can get confused.

      I surely does feel like my assumption, that the update for the A2 Lite would soon follow up after the A2, was wrong. Anyhow, I will add the info at the top and again, will update this post when the update is available for the Lite version.

      Again, thanks for your feedback on the matter.

    1. No Hamza, I wouldn’t recommend it.

      The firmware on both the devices follows a different partition layout.

  21. Hi,
    but doing the method #2, isn’t it true that I will have android 10 installed, magisk installed as well, but no TWRP? Because when you install OTA, it will substitute /boot partition of inactive slot, and twrp needs to be reinstalled in that slot.

    Or not?

    thank you

    1. Yes, Maurizio, you’re correct.

      I have yet to confirm whether we can still install the TWRP installer zip on Android 10, or not because it still poses issues with File-Based Encryption. And if that’s the case, then you might first need to disable encryption (if not already disabled) on your phone.

      Just give me a bit of time. I will clarify it. And if it does support TWRP installation permanently, then I will make sure to update the instructions of Method 2.

  22. I decide to do method 2. But i have some questions. Does OTA work after i do all steps (method 2)? I want my phone is on completely stock.
    Sr for my bad Eng.

    1. Hi Dan. If you want to stick to completely stock firmware, I would suggest using Method 1 instead. After using that, you will further receive normal OTA updates monthly.

    1. Hi Amirul. According to a recent report, Mi A2 Lite running Android 10 was spotted on Geekbench. So the update might roll out soon.

  23. PS C:\adb> fastboot flash bluetooth_a bluetooth.img
    Sending ‘bluetooth_a’ (556 KB) OKAY [ 0.017s]
    Writing ‘bluetooth_a’ FAILED (remote: ‘Flashing is not allowed in Lock State’)
    fastboot: error: Command failed

    this error showing on my screen what should i do?

    1. Hi Raj. It seems like you have not unlocked the critical partition of your Mi A2. You have to boot your phone into fastboot mode and execute the following command:

      .\fastboot flashing unlock_critical

      Note that this will erase your phone completely.

      Once the critical partitions are unlocked, you can easily flash the Android 10 fastboot image without any issues.

  24. Bro, I tried to upgrade my Mi A2 to android 10 via adb sideload… But, it fails at 47% showing that Total xfer 1.00x… What should I do?

    1. Hi Afzal. The ADB sideload method doesn’t really work on the Mi A2 via stock recovery. You would need to flash the fastboot image (see method 1).
