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).

  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.

  13. Finally, swipe the button on the screen to flash the files.

  6. Connect the phone to the PC using the USB cable.
  7. 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
  8. 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.
