How to make a full reset on Xiaomi Redmi 9: the complete guide

Xiaomi’s Redmi line of smartphones are famous for their performance and availability, but over time, even reliable devices can start to work unstable. Accumulation of system debris, errors in software updates or the need to transfer the device to a new owner are just some of the situations where a radical decision may be needed. It is at such moments that the user faces the question of how to make a full reset on the Xiaomi Redmi 9 to return the gadget to its factory state.

The factory-back process, often referred to as Hard Reset, is a powerful tool in the arsenal of any Android device owner, which allows you to completely clear internal memory of user data, applications and settings, returning the MIUI software shell to the “out of the box” state. However, it is important to understand that this action is irreversible, and neglecting preparatory measures can lead to the irretrievable loss of important photos, contacts and documents.

In this article, we will discuss in detail all available methods for resetting the Redmi 9 model, consider the nuances of working with Recovery mode and answer frequent questions that arise during operation. You will learn how to properly prepare the device, what hidden functions of the recovery menu exist, and how to avoid common errors that can turn a smartphone into a brick.

Preparation of the device before resetting settings

Before you take decisive action, you need to make sure you have completed all the necessary preparatory steps. Ignoring this stage can result in you being left without access to your accounts after a reboot or losing valuable data forever. The first and most important step is to create a full backup of all important information.

Modern Xiaomi smartphones offer built-in backup tools that allow you to save not only contacts and messages, but also the folder structure, system settings and even the location of icons on the desktop. It is recommended to use the Google Drive cloud service or the Mi Cloud proprietary cloud to synchronize critical data, as local copying is done on the Internet. SD-The card will also be affected by the cleaning procedure, unless you choose to save only system settings.

⚠️ Warning: Make sure your Redmi battery is charged 9 is 60-70%. Interrupting the reset process due to battery discharge can damage system partitions and inability to load the operating system.

Also critical is the Google account, which, once you reset, will trigger FRP (Factory Reset Protection) protection, which will require you to enter a login and password from an account that was synced to the device before the reset, and if you forget this data, it will be extremely difficult to unlock your smartphone, and in some cases impossible without contacting the service center with purchase checks.

Be sure to check for important files in download and instant messenger folders like WhatsApp or Telegram, as their correspondence history is often stored locally. For instant messengers, it is better to perform a separate backup through their internal settings to ensure that the dialog history is saved.

Reset method through system settings menu

The safest and easiest way to get the Xiaomi Redmi 9 back to factory status is to use the operating system’s regular menu, which is ideal in situations where the smartphone is functioning normally, the screen is responsive to touch, and you have full access to the interface, and it minimizes the risk of software errors because the procedure is controlled by the system itself.

To start, you need to go to the main settings menu of the device. Find a section that, depending on the version of the MIUI firmware, can be called About Phone or Advanced Settings. In newer versions of the shell, the path most often follows: select About phone, then find the button "Reset settings" or "Erase all data."

The system offers several cleanup options: you can choose a full reset that will delete absolutely all data, including files in internal memory, or a more gentle option that saves media files. For guaranteed results and a clean installation, you should choose the option of complete deletion.

Once the appropriate item is selected, the system will request confirmation of actions, you may need to enter a graphical key or a digital password to unlock the screen, a security measure that prevents unauthorized or accidental resetting of settings by unauthorized persons.

Then you'll see a warning on the screen that all data will be deleted, check the confirmation checkbox and click "Reset" (or "Next", then "OK"), and the smartphone will reboot, and the cleaning process will begin, which can take from a few minutes to half an hour depending on the amount of memory filled.

Hard Reset with Recovery Mode (Recovery Mode)

Sometimes, the smartphone stops responding to commands, freezes on the logo when it boots, or stops settings from the menu because of a forgotten password, and in such cases, a recovery mode known as Recovery Mode comes to the rescue, a special diagnostic mode built into the device’s memory regardless of the main operating system.

To enter Recovery mode on Xiaomi Redmi 9, you need to turn the device off completely. Once the screen goes out, you need to press both the Volume Up button (Vol +) and the Power button at the same time, hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume button until the recovery menu appears.

In the menu that appears, the navigation is done with volume buttons (up and down), and the choice of item is made by the power button. You need to find the Wipe Data item and select it. Next, the system can offer several options, among which we are interested in Wipe All Data.

⚠️ Attention: In Recovery mode, the touch screen is not working. All actions are performed exclusively with mechanical volume and power buttons. Don't panic if the screen does not respond to touch - this is normal behavior for this mode.

Once the reset point is selected, the system will require final confirmation, usually Confirm. Once confirmed, the data partition formatting process will begin. Upon completion of the procedure, the screen will display the words "Data wiped successfully" and the device will prompt you to return to the main menu (Back to Main Menu) or restart (Reboot).

💡

Recovery mode is the only way to reset settings if the smartphone is locked, not booting, or the touch screen is not working.

And it's important to note that this method also completely deletes all user data, and the only difference is how you initiate the process, and once you reboot, the phone will look like you just took it out of the store's packaging.

Removal of a forgotten password or pattern lock

One of the most common reasons users are looking for information about a complete reset is the banal forgetfulness: the owner may forget the pattern lock, the digital key. PIN-A code or password set to protect personal data. In the case of the Xiaomi Redmi 9, as with most modern Android smartphones, resetting settings is the main way to get around this protection.

However, it is worth dispelling the myth that reset will allow you to simply enter and use your phone. As mentioned earlier, after the cleaning procedure, the device will require authorization in the Google account that was tied to the phone before locking. This is protection against theft: if a thief steals the phone and tries to reset it, he still can not use it without the owner’s data.

The procedure for resetting to unlock is no different from the standard Hard Reset via Recovery.The only difficulty may be that some firmware versions may require a Wi-Fi connection directly to the unlock menu to verify the owner's rights through Mi Account servers.

• 🔑 If you forget the password from the Mi Account, it can be restored through the official Xiaomi website using the linked phone number or email.
• 🔑 Entering the wrong Google password several times in a row can temporarily block the ability to sign in, so enter the data carefully.
• 🔑 There are services for withdrawal FRP-blocking, but their use requires technical skills and carries security risks.

If the phone was bought with your hands and the previous owner did not untie his account, you will have to look for it to unlock the device, otherwise the phone will remain a “thing-in-itself”, unsuitable for full use.

Solving problems after resetting settings

Once the reset process is complete and Xiaomi Redmi 9 welcomes you to the initial setup screen, a number of questions and nuances may arise: the first launch after Hard Reset always takes longer than usual, due to the fact that the system needs to re-index files, update system services and check for critical security updates.

Sometimes users are faced with a situation where the phone is endlessly rebooted or "hangs" on the Mi logo. In most cases, this is a temporary phenomenon, especially if the system was updated in the background before reset. Just wait 10-15 minutes. If the boot does not occur, you may need to repeat the reset procedure through Recovery, selecting Wipe Cache (if available in your version of Recovery) or repeat Wipe Data.

Also worth noting is the battery's autonomy: In the first hours or even days after a battery is discharged, the battery can run out faster than usual, because the background synchronization processes, app updates from the Play Market and indexation are in enhanced mode, usually after 2-3 full charge-discharge cycles, the battery statistics stabilize.

If you see strange artifacts on the screen after the reset or the phone is not behaving properly, this may indicate deeper problems, perhaps hardware or damage to the system files of the firmware. In this case, a simple reset is not necessary, you will need to completely reflash the device through the computer using the Mi Flash Tool utility.
