Guide: update MIUI from Updater

There are two ways to install MIUI updates: from recovery mode (accessible by holding down the volume up and power button) and Updater. This guide explains how to update from Updater.

Alternatively, read how to update with ClockworkMod recovery by clicking here.


In the case of Xiaomi, we must specify that there are two partitions: system 1 and system 2 and that updating by Updater, the update will be done on the partition in use and upon restart the phone will automatically change to the other partition. So if for example we install on system 2, on reboot we will have system 1 and vice versa. While as far as MI recovery is concerned, it will always be possible to update only on the 1 system. IS' important have similar versions on both partitions, ie not always update the usual partition and leave the other to a dated version, in fact these differences can lead to problems.

First step: Backup (and recovery)

Updating the rom does not result in data loss, but it is always advisable to create a backup of data and even applications if you really want. It becomes necessary in case we have to restore everything, because obviously we will lose the data. It also doesn't hurt to have a good backup, because you never know what can happen! Let's see how to make a complete backup.

We enter the system app Backup and press Backup at the bottom (next to it there is also a padlock that, if activated, will encrypt our data and only by logging in from the Xiaomi account will it be possible to delete the backups made or restore our smartphone from other devices). Now we choose what to restore:

  • System: this option will make a backup of all system settings like desktop layout, camera, alarms, messages, weather, call log, notes, WiFi settings, etc.
  • Applications: all installed applications and their data
  • Accounts / Contacts: contacts address book, email, Gmail and Xiaomi account


The orange icon indicates that it will back up the selected data type, removing it will not be backed up. Furthermore, by clicking on the small arrow on the right, we can choose the types of data, for which to create a backup, individually.

For recovery we enter the backup app again and now we will notice an option, whose title is a date (ie the one in which the backup was made). Select it and choose which type of data to restore as we did previously with the backup.

Second step: Full wipe

The full wipe, or the deletion of all data and then restore to factory settings it is not always necessary. However, it is advisable to do so every few updates. I recommend every 3-4 update, otherwise we will notice some slowdown on our device or even some small bugs due to settings of old versions not compatible with the new ones.

There are two methods for wipe.

  1. From settings let's move on Backup and restore and select Factory data reset. As we can see, all our data will be deleted and in addition we can choose whether to delete all the apps we install and all the media: photos, music, etc.
  2. From recovery we choose the English language by moving with the volume keys and selecting with the power key, and select wipe. Now we choose whether to delete the cache (wipe cache), the user data (wipe data) or all (full wipe).

Third step: Update

After downloading the update package and the related Italian language pack, we connect the device to the PC via USB and copy the files to the main folder (it is not necessary to rename them if the update is done by Updater).


Now let's move to our device and open Updater, press the settings button and choose Select installation package. The File Explorer will open. Let's go down and select the update.


A new screen will warn us if we want to update, press update now.


Another screen will warn us that the terminal will be restarted at the end of the procedure and that the data will not be removed, but it is advisable to carry out a Backup. We choose to update


At the end the last screen will appear that will allow us to restart the device with the new MIUI version.


We restart and find ourselves in the other partition, then we re-run the procedure and on reboot we redo the same for the Italian language packages and the gapps. At the end we can delete the copied files in the main folder by reconnecting the terminal to the PC or simply from file explorer.

PLEASE NOTE: The version installed in this guide is the 3.9.6 which is to be installed exclusively via Updater, since through MI recovery it could have digital signature problems. Therefore it is highly recommended to proceed through Updater or through clockworkmod recovery, with which it is possible to install roms without signatures. Soon we will explain how to update with MI recovery, follow us to stay informed 😉
