Xiaomi smartphone owners often face the need to completely clean the device of accumulated digital debris. the Redmi 9, despite its popularity and reliability, can eventually start to work slower due to cache overflow or software failures. Reset to factory settings (Hard Reset) is a radical, but often the only sure way to return the gadget to the original speed and stability of the Android operating system.
The memory cleanup procedure requires pre-preparedness, as it permanently deletes all user data. Unlike simple file deletion, userdata partition formatting erases the structure of the file system, making recovery impossible without prior backup. In this article, we will discuss all available methods, including working through the settings menu and Recovery Mode.
Don’t panic if your Redmi 9 starts to behave incorrectly after updating or installing a questionable application.A well-performed reset procedure allows you to eliminate most software conflicts.We will then look at how to secure your data and correctly perform all the necessary actions.
Preparatory stage: backup and security
Before you start any manipulation of system files, it is critical to back up. The built-in MIUI tool allows you to save contacts, SMS messages, call logs and application settings to an external drive or the cloud. Go to Settings → About Phone → Backup and select the desired settings to save.
Special attention should be paid to sync with your Google account, make sure that your contacts, notes and photos are uploaded to the cloud, which will take only a few minutes, but save you from losing important information in the event of unforeseen circumstances during the reset.
The process of formatting and reinstalling system files can take anywhere from 10 to 30 minutes depending on the amount of internal memory.
- 🔋 Charge the device to minimum 60-70% before the beginning of the procedure.
- ☁️ Check the sync status of your Google account and Mi Account.
- 📁 Copy photos and documents to a computer or SD-hand-write.
- 🔐 Remember or write down passwords from your main accounts so you don’t block your phone.
Ignoring this stage can lead to the fact that you lose access to important data forever, and once formatted, it will be impossible to restore it with standard means.
☑️ Ready to dump
Method One: Standard Resetting through System Settings
The safest and easiest way to get the Xiaomi Redmi 9 back to its original state is to use a regular settings menu, which is suitable for cases when the phone is turned on, the screen responds to touch, and you have access to the desktop. The MIUI shell action algorithm is standardized, but requires careful choice of options.
To start, open the Settings menu and scroll down to About Phone. At the bottom of the screen, you'll find the Reset button. The system will offer two options: Reset all settings (without deleting personal files) and Clear all data (full Hard Reset).
Once you have selected the cleaning option, the system will request confirmation of the action, as it is an irreversible operation. You will need to enter a digital screen unlock password or a pattern lock. If the device has Find Device theft protection enabled, you may also need to enter a password from Mi Account.
⚠️ Warning: After pressing the "Clear all data" button, the phone will automatically restart and begin the erasure process. Interrupting this process by turning off the power or removing the battery (if it were removable) will damage the bootloader and turn the device into a "brick".
The whole process takes a different time, and the screen can display the MI logo or download animation, and don't try to plug your phone into an unstable current charger or do any other thing.
What to do if the reset button is inactive?
Hard Reset with Recovery Mode
If the Android operating system is damaged, the phone freezes on the logo or does not respond to touch input, you need to use Recovery Mode Recovery mode. This method works at the level of low-level software and allows you to reset even when the interface is broken.
To enter recovery mode on Redmi 9, you need to turn the device off completely. Then press both the Volume Up and Power button at the same time. Hold them until the Mi logo appears, then release the power button, continuing to hold the volume button until the Main Menu menu appears.
Navigation in this menu is done with volume buttons (up/down), and the power button selects the item. You need to find the Wipe Data item and confirm the selection. In the next menu, select Wipe All Data and confirm the action by selecting Confirm.
The login algorithm for Recovery:
1. Turn off the phone completely.
2. Clamp Volume Up + Power.
3. Hold until the Mi logo appears.
4. Release Power, hold Volume Up until the menu appears.Once the cleaning process is complete, the system will suggest returning to the main menu (Back to Main Menu) or restarting (Reboot). Select Reboot to System. The first on-off after a reset will last longer than usual, as the system partitions are initialized.
💡
If the Recovery menu does not appear, try connecting the phone turned off to your computer via the Recovery Menu. USB-And you can do it again, and on some firmware versions, it's a requirement.
Resetting a forgotten password and unlocking the device
A common reason for resorting to reset procedures is a forgotten pattern lock or password. Unfortunately, modern versions of Android and MIUI have a high level of protection, and it is almost impossible to get around the lock without losing data. Recovery reset is the only legal way to regain access to the device.
But once reset and turned on, the phone can request Google or Mi Account data that was previously linked to the device, which is a feature called FRP (Factory Reset Protection) security, designed to protect the owner's data in the event of a theft, and if you don't remember that data, it will be extremely difficult to unlock the phone.
It is important to understand the difference between the lock screen password and the account password. Reset removes the screen password, but does not remove the account binding, so before reset, it is advisable to untie the accounts in the settings if access to the menu is still available.
- 🔑 FRP Blocking requires entering the last used Google account.
- 📱 Mi Account may require confirmation code sent via SMS.
- 🚫 Reset does not remove activation lock if phone is wanted.
- 🛡️ Theft protection works even after flashing the device.
If you buy a used phone and it is blocked by the previous owner, the only way out is to contact them to remove the device from your account remotely via i.mi.com or google.com/android/find.
Table of comparison of discharge methods
The choice of the specific method depends on the current state of your Redmi 9. Below is a comparison table that will help determine the best way to solve the problem.
| Parameter | Through Settings. | Through Recovery. | Through the Mi PC Suite |
|---|---|---|---|
| Access to the menu is required | Yes. | No. | Partially (Fastboot mode) |
| Risk of software damage | Minimum | Medium. | High-pitched |
| Deletion of all data | Yes (when choosing an option) | Yeah (always) | Yes. |
| Difficulty of implementation | Low. | Medium | Tall. |
As you can see from the table, the most preferred method for the average user is through settings, since it is controlled by the system and is less prone to errors.
The use of computer utilities is recommended only for experienced users familiar with the firmware procedure, since an error in choosing a version of the software can lead to the need for maintenance repairs.
Possible problems and solutions
During or immediately after the reset, users may encounter a number of typical problems, such as the phone may freeze during the boot phase (Mi logo). If waiting more than 15-20 minutes does not work, try forcibly restarting the device by holding the power button for 10-15 seconds.
Another common problem is cyclic reboot, which may indicate damage to system files or hardware conflict, in which case you may need to completely flash the device through the computer using the Mi Flash Tool utility.
⚠️ Warning: If the touch screen stops responding or is not working properly after reset, this may be a sign of a hardware malfunction that coincides with a software failure.
Also worth mentioning is the heating problem. After you first turn on and restore the backup, the phone can get very hot. This is normal, because the system indexes files and updates applications in the background. Let the device cool down and don't load it in the first hour of operation.
💡
Cyclical reboot after reset is most often solved by complete flashing or waiting for the completion of background processes within 1-2 hours.
