Do you want to optimize the Xiaomi Mi A2 performance? If you envy the pure Android UI that runs on Android One branded devices and if you’re ready to apply the right customizations on your smartphone for improving the overall Android experience, we might have the right solution for your problems. A new custom ROM based on Android 8.1 Oreo is available for your Xiaomi Mi A2 and it might be the perfect Android system in terms of optimization and customization opportunities. We’re discussing about the Mokee OS, which can now be successfully installed on the Mi A2.

Mokee OS is one of the best custom ROMs that can be used on Chinese branded handsets as it comes with a pure Android touch. This Android 8.1 Oreo iteration is light, stable and smooth. It will ensure improved speeds on your Xiaomi Mi A2, it will upgrade the battery life and it will upgrade general performance. Additionally it will add features, apps and capabilities which cannot be found on the stock Oreo firmware. And with these extra features you can afterwards tweak your device and customize / optimize the Android functionality depending on what you want to achieve from your phone.

Of course, if you want to apply this custom ROM on your device you need to know some things first. The most important aspect is related with the Xiaomi Mi A2 warranty which will be void once the update operation will be initiated. As already outlined, the Mokee OS platform is developed by third party devs. It has nothing to do with your OEM or with Google so it’s not an official firmware that can be OTA received. It’s based on the stock Android 8.1 Oreo UI and represents a free aftermarket distribution of the official Android OS. Therefore, you will be using a modified build of the stock Android OS and not the official software and that’s why you will lose the warranty flag – the warranty can be restored only if you choose to reinstall the stock Android OS on your device.

You have to backup your Xiaomi Mi A2 before beginning the flashing process. Do that especially because a full wipe must be completed in our case – the stock Android OS can be replaced with a custom ROM only if a hard reset if applied first. So, just use your favorite backup and restore solutions for protecting your personal data, info, accounts and files: use an external storage device, sync files with your Google Account, use the built-in cloud storage apps or download backup and restore apps from Google Play. With these backup and restore solutions you should be able to quickly save stuffs like contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, IMEI / NVRAM data and so on.

Another optional, but recommended operation is the Nandroid backup one. This process helps when you want to secure the actual Android UI: it patches a copy of the Android OS that already runs on your device. So, if the new Mokee OS isn’t performing well enough, you can choose to go back to stock easily by flashing the Nandroid backup package.

If you decided to resume this Android 8.1 Oreo update operation first make sure that your Xiaomi Mi A2 runs on an unlocked bootloader. Root access should also be gained and a custom recovery image must be there too. As you will notice the update process will be completed from the custom recovery environment and our recommendation is to use the TWRP recovery platform for the best and easiest flashing experience.

You will have to use a computer, but don’t worry as you won’t have to install and use third party flashing programs: the update operations will be completed from TWRP recovery so from this perspective you have nothing to be worried about. Now, your Mi A2 and its official USB cable must be near you as a connection between your phone and your computer will be required in a few moments.

On your smartphone you have to access Developer Options. Usually, this field should be displayed under general Settings; if it isn’t, go to About Phone and from there start tapping repeatedly on Built Number – after 7 or 10 repeated taps the ‘you are a developer’ message should be returned. Finally, from Developer Options enable the USB Debugging feature.

Charge your Xiaomi Mi A2 before starting flashing the Android 8.1 Oreo based Mokee OS update package. It’s important to provide enough power for the installation procedure as otherwise a sudden shut down might happen – we recommend you to plug in the charger if the power left is lower than 50%. Do note that the Android UI can get soft bricked when sudden shut downs occur – software related problems might be caused within the Android core system.
