Are you trying to use your Xiaomi Mi A2 but you cannot do it properly? If there are malfunctions which are causing software-related issues don’t worry as today we will see how these general Android problems can be easily and quickly fixed. Thus, we will now discuss about the troubleshooting solutions available for the Xiaomi Mi A2 and which can be applied for addressing different malfunctions that interfere with the main Android functionality. Of course, this ‘unbrick’ tutorial contains additional info that can further explain the reasons why such problems can be experienced in the first place.

Therefore, read all the lines from this guide before doing anything else. Also, make sure you review the advantages of each troubleshooting method, the risks that might be implied and the essential pre-requisites that should be first performed. Only in this way you can properly unbrick your Xiaomi Mi A2.

Right from the start we need to explain one thing in particular: the guidelines detailed below will work for the Xiaomi Mi A2 and are related only with software relates issues and malfunctions. That’s why, if your device isn’t running because you managed to damage some of its hardware components, you should take your smartphone back to service as we cannot help you out. Once more, the troubleshooting methods presented during this tutorial are discussing only problems caused by the Android system, or by third party software.

Also, all the methods described are official operations, supported by Xiaomi and by Google. You won’t risk, at any moment, to lose your Xiaomi Mi A2 warranty or access to built-in apps. Moreover, you don’t have to use third party tools, complex apps or risky programs in order to fix the issues that are causing malfunctions within the Android core system. What we will try to do is to partially, or fully (depending on how severe is the actual problem), restore your device back to its factory state. In that respect you might lose some files during the troubleshooting initiative.

Therefore, a backup should be completed first – of course, if that’s still possible. As a general idea, a proper backup can be applied by using Xiaomi’s cloud storage services which should already run on your Mi A2, or by syncing files with your Google Account. Another way in which you can quickly save your personal data, info, accounts and files is by using dedicated, and already tested, backup and restore apps from Google Play. The goal should consist in saving as much as possible – just don’t forget about essential files like contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and similar other packages.

In most situations you can end up in experiencing issues while using your Xiaomi Mi A2 if you are not careful what you download and install on your device. Always choose to download already tested apps and always download the tools from trustful sources. Also, be careful when setting up third party apps or programs that might come along with deceptive features or with malware. And, of course, if you like tweaking operations, always follow dedicated and detailed tutorials.

Since the Android OS is an open source platform it is quite easy to end up in messing things up. And, if you don’t know what went wrong you will end up in dealing with a soft-bricked Xiaomi Mi A2. And the most usual problems are these ones: boot loops, lags, hangs, screen freeze, battery drain, heating issues, signal strength problems, total blackouts and similar other malfunctions. Now, such issues are most likely caused by a malware, an unresponsive program, a malicious app or an inappropriate tool. That’s why you need to remove the software that is causing the issues and that’s why you need to partially or fully restore your handset to its factory state.

Do note that the steps from below will work regardless of the state in which your Xiaomi Mi A2 is currently found. Moreover, these troubleshooting solutions will work even if your smartphone is rooted, running on a custom ROM firmware, powered by an unlocked bootloader or installed with a custom recovery image – if you choose to apply the last method from below, then you will eventually lose these tweaks as root access will be revoked, the bootloader relocked, the stock recovery image reinstalled and the bloatware re-applied.

Good; now it’s important to ensure enough power for the actual troubleshooting methods as if the power is low your Xiaomi Mi A2 can get turned off right while you try to unbrick its Android system. And, if a sudden shut down happens you can only end up in experiencing further problems. So, it’s important to avoid such unpleasant events – you can easily do that by verifying the amount of power that’s left on your phone (if you cannot do that, just plug in the charger for a while) – we recommend to charge your device if it’s power is currently lower than 50%.

Of course, keep in mind that this step by step guide is compatible only with the Xiaomi Mi A2; don’t try the steps detailed below if you own a similar or a different Android based device.

How to Unbrick the Xiaomi Mi A2

Solution 1 - Enter Safe Mode

The first troubleshooting solution that you should try is the ‘safe mode’ one. Just like when using a Windows based computer, on Android you can boot your Xiaomi Mi A2 into safe mode for being able to isolate a certain problem and for resolving it, if that’s possible. How that works? Well, by default, in safe mode all third party apps and processes are disabled. Shortly, if your Xiaomi Mi A2 issues are caused by a third party app or feature, in safe mode the problem will not be shown. And, in that case you will know that a recently installed software is the reason why you cannot use your phone properly and you can therefore easily remove this issue. On the other hand, if the problems persist in safe mode it will mean that the malfunctions are not related with a third party program or app and that you need to further investigate. You can easily reboot safe mode on your Xiaomi Mi A2 by following the steps explained below:

  1. Switch on your smartphone.
  2. Long press on the Power button in order to bring the Boot menu (don’t press too long on Power key as you will manage to switch off your device).
  3. From the Boot menu press and also hold down the Power Off area/section.
  4. A prompt will be displayed asking whether to boot into safe mode or not.
  5. Tap on OK and wait while your Xiaomi Mi A2 is being automatically turned into safe mode.
  6. That’s all; you can go back to Android mode easily by initiating a regular reboot.

Solution 2 - Make a hard reset

If you couldn’t isolate and fix the problem from safe mode you should take a more drastic measure: making a hard reset. This solution will partially restore your Xiaomi Mi A2 to factory state as a full system wipe will be completed – you will erase everything that wasn’t there from day one so don’t forget to make the backup first, if you want to protect your personal files. Now, this full wipe will remove your data but it will also erase any possible malware, or potential harmful programs and processes. It’s a great way to refresh the Android system when general malfunctions are being caused; and hopefully, it should also help you fix the problems that are running on your own handset.

Use our dedicated tutorial and learn how to hard reset the Xiaomi Mi A2 (there are two ways in which this operation can be completed, so choose the one that you prefer the most).

Solution 3 - Clear app data cache

Sometimes the hard reset is not enough as there might be hidden files and processes left behind. In those situations you should also choose to clear app data cache in order to fully wipe the internal storage system of your Xiaomi Mi A2. Well, doing so can be done easily, from recovery mode menu, as detailed during the next steps:

  1. First of all, put your Xiaomi Mi A2 into recovery mode.
  2. In recovery mode use Volume Rocker keys to scroll up and down and the Power button to select.
  3. First of all, complete (or repeat) the hard reset process.
  4. Then, choose ‘wipe cache partition’.
  5. In the end return to main menu of recovery and pick ‘advanced’ and afterwards select ‘wipe dalvik cache’.
  6. When done, from main menu of recovery choose ‘reboot system now’.
  7. That should do the trick.

Solution 4 - Reinstall the Stock / Default Android OS

If the methods explained above aren’t working for you, then it’s time to fully restore your Xiaomi Mi A2 back to its default state. And as you can already tell, this can be done by manually reinstalling the stock / official Android firmware. This will ensure a system refresh as everything will be reinitiated on your smartphone. The OS installation process will remove the third party apps that were flashed during time and will remove any other file that wasn’t there by default. So, this solution should fix any software related issue that might still cause malfunctions on your smartphone.

Of course, if tweaks were previously ensured now you will also manage to unroot your Xiaomi Mi A2, to relock your phone’s bootloader, to reinstall the stock recovery image and to re-apply the built-in apps and features.

Unfortunately, your personal data, info and accounts will be removed so don’t forget about the backup that was already recommended before.

The manual installation process will require a computer, where the drivers for your Xiaomi Mi A2 should be first flashed. Of course, your phone and its USB cable will be needed too. On your phone you should first enabled Developer Options: from About Phone (located within General Settings) tap repeatedly on Built Number until the ‘you are a developer’ message pops up. And afterwards, from Developer Options (go to Menu - > Settings) you have to check the USB Debugging field.

On your phone you have to download and set up the Xiaomi Mi Flash Tool (you can download the flashing program from this page). Also, you need to download and unzip the full firmware package that’s available for your Xiaomi Mi A2 (you can get it from any source you prefer). Then, put your Xiaomi Mi A2 into fastboot mode, run the Mi Flash Tool on your computer, connect your phone with your PC and follow on-screen prompts displayed on the flashing program for completing the update operation.

But in my, (probably) typical scenario, the phone boots and freezes at the Android start screen, or freezes at the Fast Boot screen, then automatically powers down after a couple of minutes. Repeat.
ADB access has not been previously enabled (dammit!).
There seems to be no way of fixing this.
Or is there?
