The Android operating system installed on Xiaomi smartphones can accumulate software errors over time, which manifest themselves in the form of sudden freezes, slow interface or network connection problems. If your Mi 9T Pro device begins to behave unpredictably, the most effective solution is often a complete return to the original state, which deletes all user data and returns the MIUI software shell to the state “out of the box”.
In this article, we will take a look at all the available methods for performing this procedure, from the standard settings menu to advanced ways through Recovery Recovery mode. You will learn how to properly prepare the gadget for cleaning so as not to lose important contacts and photos, as well as how to bypass blocking a Google account in case of need to resell the device.
There are several scenarios in which such a radical measure is really necessary, from the banal sale of a gadget to the elimination of the consequences of a failed firmware update, it is important to understand that Hard Reset is an irreversible operation, so it should be approached consciously and with a full backup of data on hand.
Preparing the smartphone for a complete reset
Before you start the cleanup process, it is critical to perform a series of preparatory steps that will secure your personal data and ensure the successful completion of the procedure.The first step should always be to back up all important information, since after pressing the reset button, it will be impossible to restore deleted files using standard methods.
Make sure that the battery is at least 50-60%, as interruption due to battery discharge can damage the system partitions and turn the phone into a “brick”.It is also worth checking whether you have a Mi Account and a Google account, as their data may be required to confirm the rights of the owner after the reboot.
☑️ Checklist before reset
Remember to remove the MicroSD card if it is installed so you don’t accidentally format it along with the phone’s internal memory, which many users forget, losing the archives of photos that have been stored on the external drive for years.
💡
Before reset, sync your contacts with your Google account – this is the quickest way to restore your phone book after cleaning.
Method 1: Reset via the MIUI settings menu
This is the easiest and most secure method that works for most users whose phones are functioning normally and have access to the desktop. First, open the Settings app and scroll down to the bottom of the About Phone item, which is where the system management tools are hidden.
In the menu that opens, look for the “Reset” section and select “Erase all data” option, and the system will warn you that all files, including photos, music and installed applications, will be permanently deleted. If the device has a screen unlock password, it will need to be entered to confirm the operation.
⚠️ Warning: If the device has Find Device enabled, the system will require you to enter a password from your Mi or Google account before you start cleaning.
Once confirmed, the phone will automatically restart and begin the cleaning process, which can take 5 to 15 minutes depending on the amount of memory filled, and when completed, you will see a screen of initial setup, as when you first turn on a new smartphone.
💡
Resetting via the settings menu is the only way to guarantee that accounts are deleted before clearing, which eliminates the problems of blocking FRP.
Method 2: Hard Reset with Recovery Mode
If the smartphone does not turn on, freezes on the logo or does not respond to touching the screen, the only way out is to use Recovery mode.This method allows you to clean even when the MIUI interface is not working, using only physical control buttons.
To enter recovery mode, you need to turn off the device completely, and then simultaneously press the volume button and the power button. Hold them until the Mi logo appears on the screen, after which the power button can be released, continuing to hold the volume until the main menu appears.
Navigation in the Recovery menu is done with volume buttons (up/down), and the choice of item is confirmed by the power button. You need to find the Wipe Data item, select it and confirm the action by selecting Wipe All Data. The system will again request confirmation, after which the formatting will begin.
What to do if the Recovery menu is in Chinese?
Unlike resetting through settings, this method may not remove the account binding, which will result in a password request after the reboot. Use this method only if access to the settings menu is impossible or you are confident in your credentials.
Method 3: Remote reset via Google Find My Device
In situations where the phone is lost or stolen, but is connected to the Internet, you can reset remotely through the service Google Find My Device.
From the device list, select your Xiaomi Mi 9T Pro and click the “Clean the Device” button in the action menu. The command will be sent to the phone, and once it contacts the server, the complete deletion process will begin. This method is only effective if there is an active Internet connection on the device.
It’s worth noting that after this cleaning, the phone may require you to enter a password from your Google account the next time it turns on, a standard anti-theft procedure known as FRP lock (Factory Reset Protection) that can’t be circumvented without the original credentials.
| Resetting method | Access to OS is required | Keeping accounts. | Difficulty |
|---|---|---|---|
| Settings menu | Yes. | No (removes) | Low. |
| Recovery Mode | No. | Yes (remains) | Medium |
| Google Find My Device | No (remotely) | Yes (remains) | Low. |
Solving FRP and Google Account Problems
After performing a hard reset via Recovery or remotely, the Android security system activates FRP lock.This means that when you first set up the phone will require you to enter a login and password from the Google account that was synced with the device before the reset.
If you forget your password, you can restore access through the account recovery procedure on any computer or other phone by clicking on the link "Forgot your password?" on the login screen. Without entering the correct data, you will not be able to unlock the device by legal methods.
⚠️ Warning: When buying a used phone, always ask the seller to reset through the settings menu with you, which ensures that their accounts are deleted and no locks are blocked. FRP post-boot.
Owners of the Mi 9T Pro should also remember to be tied to the Mi Account. If the “Find Device” function is enabled, the phone will request a password from the Xiaomi account immediately after connecting to Wi-Fi. Ignoring this request will not be possible, since the system will block the basic functions of the device.
Initial adjustment after reset
Once you have successfully completed the cleaning and reboot procedure, you will be presented with a welcome screen with a choice of language, select the desired language and connect to the Wi-Fi network, as some functions may require the Internet to activate and verify the license.
In the setup phase, the system will suggest recovering data from a backup. If you've previously created a backup in the Google cloud or through the Mi Cloud app, you can choose it to restore contacts, call history and installed app list, a process that can take some time depending on the speed of the Internet.
It is recommended that you do not miss the update phase of system components and applications of Google Play Services, if the system suggests doing so, this will ensure stable operation of the smartphone and eliminate possible security vulnerabilities that are relevant at the time of release of the firmware.
💡
When you first set up, turn off automatic application updates via the mobile network so as not to waste traffic and battery.
