Modern smartphones begin to work slower over time, having accumulated many errors in the system or unnecessary files. For owners of a popular model Xiaomi Redmi 9 returning to its original state is often the only way to restore the device to its former speed. This procedure completely clears the internal memory of the phone, deleting all user data, applications and changes that were made during operation.
Restoring factory settings may be required in various situations: from selling the gadget to a new owner to eliminating critical software failures. It is important to understand that resetting settings is an irreversible process that will return your Redmi 9 to the state in which it was immediately after purchasing it out of the box. Before starting any manipulations, you need to understand the consequences and carefully prepare so as not to lose important contacts or photos.
In this guide, we will analyze in detail all the available methods for performing this operation, starting from the standard settings menu and ending with the emergency Recovery mode. You'll learn how to properly prepare your device, what steps to take if your phone is locked, and how to avoid common mistakes. Follow the instructions carefully to return your smartphone to its pristine system cleanliness.
Preparing the device for a full reset
Before initiating the cleaning process, it is critical to save all valuable information. After clicking the confirmation button to delete the data, it will be almost impossible to restore it without a preliminary copy. Backup must include contacts, messages, photos, videos and document files. The ecosystem MIUI has a built-in tool for this, which allows you to upload data to the cloud or to an external drive.
Make sure that your battery charge Xiaomi Redmi 9 is at least 50-60%. The process of formatting internal memory requires stable power consumption, and if the phone turns off in the middle of the operation, it can damage the system partitions. It is best to connect the device to the original charger and leave it plugged in until all procedures are completed. It is also recommended to remove the memory card MicroSDif it is installed to avoid accidental formatting of external media.
Don't forget to unlink your account Google and account Mi Accountif you plan to sell the phone. This is necessary so that the new owner does not encounter an activation block. If the reset is done for personal use in order to eliminate errors, just make sure that you remember the passwords for your accounts, since after a reboot the system will require you to enter them to verify the owner.
โ๏ธ Preparing to reset your settings
Reset through the settings menu MIUI
The easiest and safest way to return Redmi 9 to the factory state is to use the standard operating system interface. This method is suitable for situations where the phone turns on, the screen responds to touches, and you have access to the desktop. The algorithm of actions is intuitive, but requires care when selecting menu items, since the names may differ slightly in different firmware versions.
First, open the โSettingsโ application and scroll the list to the very bottom. Find the section About the phone and tap on it. In the menu that opens, you must select the item Reset settings. The system will offer several options, but we are only interested in option Delete all data. Clicking on this button will start the preparation process, during which the system will check for active accounts and warn about the loss of information.
After confirming the action, the phone will ask you to enter a screen unlock password or PIN code from the SIM card for security. Once the protection is passed, the removal process will begin. The screen will go dark and the device will reboot. A logo will appear on the screen Redmi and a progress indicator, which may freeze at a certain percentage for several minutes - this is a normal phenomenon, indicating a deep cleaning of the memory partitions.
Before resetting through the settings menu, disable the โFind my deviceโ function in the Mi account to avoid additional password requests when setting up the phone for the first time after a reboot.
Using Recovery mode to reset
If your smartphone freezes, does not boot to the desktop, or you forgot the pattern key, mode Recoverycomes to the rescue. This is a special diagnostic mode built into the deviceโs memory, which allows you to control the system bypassing the main interface Android. Entering this mode on Xiaomi Redmi 9 is carried out by a combination of physical buttons when the power is off.
To get to the recovery menu, turn off the phone completely. Then simultaneously hold down the volume up button (Volume Up) and the power button (Power). Hold them down until the logo Miappears, then release the power button, but continue to hold the volume down until the main menu MIUI Recoveryappears. Navigation in this mode is carried out using the volume buttons (up and down), and the selection of an item is confirmed with the power button.
In the list of available actions, select the item Wipe Data. The system may request confirmation by asking you to select Wipe All Data. Confirm the action by selecting Confirm. After cleaning is complete, which will take 2 to 5 minutes, select option Rebootand then Reboot to System. The phone will reboot and begin the initial setup as if it just came from the store.
What to do if the Recovery menu is in Chinese?
If when you enter recovery mode you see hieroglyphs instead of English text, then the Chinese version of Recovery is activated. To switch to English, select the top menu item (usually a button with a globe icon or just the first line), confirm the choice, and the interface will change to clear English.
Deleting a Google account and resetting protection
One โโof the most important security measures in modern smartphones is the function FRP (Factory Reset Protection). It is designed to protect the device from theft: if the phone was reset to factory settings through the Recovery menu or buttons, upon first boot it will require you to enter the login and password for the account Googlethat was synchronized with the device earlier. This makes it pointless to steal the phone for the purpose of reselling it after the reset.
If you are performing a reset to sell or transfer the device to another person, it is critical to delete the account Google before starting the procedure. Go to Settings, find the section Accounts and synchronization (or simply Accounts). Select your email address Gmail and click the button Delete account. Repeat this procedure for all linked accounts, including Mi Account.
Ignoring this step will result in the new owner not being able to activate the phone. He will need to contact you to obtain your password, which will create inconvenience for both parties. If you buy a used device, be sure to check whether the previous owner reset the accounts so as not to end up with a locked activation screen.
Solving problems after resetting the settings
After successfully completing the procedure and the first boot, users may encounter a number of questions or non-standard system behavior. The first startup after a reset always takes longer than usual as the system optimizes applications and indexes files. Don't panic if the phone hangs on the welcome screen for 5-10 minutes - give it time to complete background processes.
Sometimes after restoring factory settings, increased battery consumption is observed in the first day. This is because background services are actively working to restore connections and check for updates. Usually the situation stabilizes within 24 hours. If the problem persists longer, itโs worth checking whether any โheavyโ applications were automatically installed from the backup.
The table below shows common situations that arise after the reset and how to solve them:
| Problem | Probable cause | Solution |
|---|---|---|
| Requires Google account password | FRP protection has worked | Enter the details of the account that was on the phone before the reset |
| Fingerprint does not work | Biometric data has been deleted | Reset the fingerprint in the security menu |
| Absent contacts | Synchronization is not enabled | Sign in to your Google account and enable contact synchronization |
| The phone gets very hot | Indexing media files | Wait a few hours or overnight with connected charging |
The first boot after a reset can last up to 10-15 minutes - this is a normal system initialization process, do not interrupt it.
Frequently asked questions about resetting Xiaomi Redmi 9
Despite the apparent simplicity of the procedure, users often have specific questions, concerning the nuances of operation MIUI and hardware Redmi 9. Below are answers to the most popular queries that will help clarify controversial issues and avoid mistakes.
Will the Android operating system be deleted when resetting?
No, the operating system is not deleted. Resetting to factory settings only affects the partition with user data (/data) and the cache (/cache). The firmware itself, version Android and shell MIUI remain the same as they were before the reset. If you updated to a new version of Android, after resetting you will have this new version, and not the one with which the phone was purchased.
Is it possible to reset the phone if the screen is broken and the sensor does not work?
If the sensor does not work, but there is an image, you can try connecting a USB mouse via an adapter OTG. This will allow you to control the cursor on the screen and go into the settings to reset. If the screen is black or completely faulty, you will need to connect to a computer and use specialized software to send commands via ADB, which requires USB debugging to be enabled previously.
Is the MIUI version reset when returning to factory settings?
No, the shell version is not rolled back. Many users mistakenly believe that a reset will return the old firmware version. In fact, you will receive a โcleanโ system, but the version that is currently installed. To roll back the version, a complex flashing procedure is required through the mode Fastboot with an unlocked bootloader.
What to do if the phone is stuck on the Redmi logo after a reset?
If the download lasts more than 20 minutes, system files may have been damaged. Try performing a force reboot by holding the Power button for 10-15 seconds. If this does not help, you need to enter the mode again Recovery and repeat the procedure Wipe Data. In the worst case, you will need to flash the device via a computer.
Will photos and videos be saved if they were on the memory card?
During a standard reset through the settings menu, the memory card is usually not formatted, and the data on it is saved. However, when resetting via Recovery mode, in some firmware versions there may be an option to format the internal storage, which does not affect the SD card. However, a safety rule is: always remove the memory card before starting any operations with the phone's memory.
If you reset your phone due to constant freezes, after setting it up, do not restore all applications at once from the backup. Install them one at a time to identify a possible problematic application causing crashes.
โ ๏ธ Attention: The menu interface
Recoveryon different firmware versions MIUI may be visually different. The color of the buttons and fonts may change depending on the theme, but the logic of the location of the items (Wipe Data,Reboot) remains unchanged in all official builds for Redmi 9.
