Redmi 9 smartphones are known for their reliability, but over time, even the most stable MIUI system can start to fail. Users often face a slowdown in the interface, sudden app freezes or a buildup of system debris that cannot be removed with standard cleaning tools.
The reset procedure, known as Hard Reset, completely removes all user data, returning the software to the "out of the box" state.This is a radical but often necessary step before selling a gadget or after a failed update. It is important to understand that recovery takes time and requires proper preparation so as not to lose important information forever.
In this guide, we will take a closer look at the process for the Xiaomi Redmi 9, and you will learn about two main methods of performing the operation: through the standard settings menu and using the Recovery mode control buttons, and we will also focus on security issues such as deleting your Google account to avoid blocking problems after a reboot.
Preparing the device for a complete data reset
Before you start any manipulation of system files, you need to perform a number of preparatory steps. Ignoring this stage can lead to loss of contacts, photos and access to accounts. First, back up all important data on a cloud server or external drive.
Make sure the battery is at least 60-70%, erase data and reinstall system components energy-intensive. If the phone turns off in the middle of the procedure, it can damage memory parts and cause the device to fail. Connect the smartphone to the charger or make sure the battery is stable.
⚠️ WARNING: If you plan to sell your phone or give it to another person, be sure to pull it out. SIM-MicroSD card and memory card: otherwise, new owners will gain access to your personal data and may accidentally delete it irrevocably.
The Android security system has a built-in anti-theft mechanism (FRP). If you simply erase data without untiing accounts, the phone will require you to enter a password from the previous owner on the first activation. Without this data, it will be almost impossible to unlock the device.
☑️ Checklist before reset
Method 1: Reset via Android Settings Menu
The easiest and safest way to get the Xiaomi Redmi 9 back to factory status is to use the built-in operating system tools.This method is suitable for cases where the phone turns on, the screen responds to touch, and you have access to the desktop.
To start, open the main app menu and find the Settings icon. In the settings list, scroll down to About Phone. This is where the basic device information and the system management tools are concentrated. Select Reset, which is usually located at the bottom of the screen.
The system will offer several cleanup options, we're interested in the option to erase all data, and when you select this option, the phone will warn you that all files, applications and settings will be deleted. PIN-code or pattern lock, the system will ask you to enter it to confirm the operation.
- 📱 Click on the button Next in the confirmation window that appears.
- ⏳ Expect to complete the process, which can take 5 to 15 minutes.
- 🔄 The phone will automatically restart and start the initial setup.
💡
Before you click the final "Reset" button, check again if your contacts are synced with Google. Often users forget that numbers are only stored in the phone's memory, not in the cloud.
Once the procedure is complete, the smartphone will turn on in initial configuration mode, as if you just took it out of the package, you will need to re-select the language, connect to Wi-Fi and log into your Google account to restore the applications.
Method 2: Hard Reset with Recovery Mode
If the phone is stuck on the logo, does not respond to touch screen or can not boot the operating system, the method of forced reset via Recovery Mode is used.This mode works regardless of the state of the main system and allows you to control the device at a low level.
To enter recovery mode on Redmi 9, you need to turn the device off completely. Then simultaneously press the Volume Up and Power buttons. Hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume key.
When the Main Menu comes up, you can control the volume buttons (up/down) and the power button (select). The navigation here is graphical, but without touch control. Select Wipe Data and confirm the action.
What to do if the menu does not appear?
⚠️ Attention: In Recovery mode, the touch screen is not working. All actions are performed exclusively with mechanical buttons. Do not try to poke at the screen, this will not work and can damage the matrix if pressed hard.
The system can re-request confirmation. Select Confirm and start the cleanup process. Once it's done, select Reboot to restart your phone as normal, and this method is guaranteed to delete all data even if the file system is damaged.
Deleting Google Account and Protecting FRP
One of the most common problems after a reset is FRP (Factory Reset Protection), a security mechanism that prevents the use of a stolen device, and if a Google account is added to a phone, it will require that the password be entered from that account after the reset.
To avoid blocking, you need to unblock before resetting through the settings menu. Go to Settings, look for Accounts and Sync or Google. Select your email address and click Delete Account or Sign Out.
A similar procedure is worth doing for Mi Account. In the settings menu, find Mi Account, log in to your profile and select the exit, and only after all associated accounts are deleted can you safely reset your data.
| Action. | The risk of blocking | Action required |
|---|---|---|
| Resetting with untied accounts | Absent. | Standard setting only |
| Resetting with active Google | High (FRP) | Need a password from Google |
| Resetting with an active Mi Account | Medium. | I need a password from Mi. |
| Hard Reset buttons | critical | You need passwords. |
If you forget your account password, you can restore access through your computer using Google's restore procedure, and without this step, your phone will become a brick with limited functionality.
Solution: The phone does not turn on after resetting
Sometimes, after the reset procedure is completed, the user is faced with a situation where Redmi 9 does not turn on or hangs indefinitely on the logo.This can be caused by damage to system files during the recording process or lack of space for temporary files.
First of all, try to do a forced reboot, press the Power button and hold it for about 15-20 seconds, and if that doesn't work, re-enter Recovery mode and try resetting again, making sure the battery is fully charged.
If the problem persists, the recovery partition or bootloader may be damaged, in which case it may be necessary to flash the device through the computer using the Mi Flash Tool utility. However, for most users, resetting or waiting (up to 30 minutes in the first turn on) solves the problem.
- 🔋 Check the integrity of the charging cable and power supply.
