Xiaomi smartphones are known for their performance and availability, but even reliable devices can become unstable over time. Budget users, in particular owners of the Redmi 9A model, often face the need to return the gadget to a factory state, this can be caused by selling the device, transferring it to another person or simply wanting to clean the system of accumulated software debris.
A complete reset procedure known as Hard Reset deletes all user information, including contacts, photos and installed apps. Before starting any manipulation, it is critical to understand the consequences of this action.
In this guide, we will take a look at all the available methods for returning the Redmi 9A to its original parameters. We will look at the standard MIUI operating system tools, as well as the recovery menu for cases when the phone is not turned on or locked. Follow the instructions carefully to avoid errors.
Preparing the device for a complete data reset
Before you start active actions, you need to perform a number of preparatory activities. Ignoring this stage can lead to irretrievable loss of important information or locking your account. First of all, make sure that the battery charge is at least 50-60%. If the process is interrupted due to discharge, the operating system can be damaged.
The second critical point is the Mi Account and Google Account. Android security has built-in protection against theft. If you reset without deleting your accounts in advance, the next time you activate your phone, you'll need to enter the password from the last Google account you used, and without that, the device will become a brick.
⚠️ Note: If you forget your Google account password after resetting, unlock Xiaomi Redmi 9A It will be extremely difficult and often only possible through a service center with a check for purchase.
It's also recommended that you remove the MicroSD card if you have it installed. Although the system usually asks if you need to clean the external storage, physically extracting the card ensures that your personal files on it stay intact.
☑️ Checklist before reset
Reset method through the MIUI settings menu
The safest and easiest way to return the Redmi 9A to factory settings is to use the built-in menu if the phone turns on and the screen responds to touch, a method preferred because it is less stressful for the file system and ensures that all partitions are deleted correctly.
To start, go to the main menu and select the Settings icon. In the list that opens, you will find the About Phone item, which is usually located at the bottom of the list, and this is where the basic tools for managing the system and device information are concentrated.
Inside the About Phone section, you'll see the MIUI logo and firmware version. On the right or bottom (depending on the shell version) there'll be a three-dot button or a direct Reset button. Click on it to go to the cleaning type.
The system will offer two options: Reset all settings (without deleting personal files) and Erase all data (full reset). We need the second option. After choosing Erase all data, a warning will appear that all files will be deleted. Confirm the action by entering a pattern lock or pin code, if installed.
💡
If the phone thinks long before resetting, don't press the buttons repeatedly, which can cause the process to freeze.
Once confirmed, the deletion process will begin, which will take 5 to 15 minutes, the device can reboot several times, during which time the Android logo or MIUI can be displayed on the screen, as well as the progress scale. Do not interfere with the operation of the smartphone until the welcome screen appears.
Hard Reset with Recovery Mode (Recovery Mode)
There are different situations: the phone can freeze, not respond to touching the screen or forget the pattern lock, and in such cases, recovery mode, or Recovery Mode, comes to the rescue, which is a low-level environment that allows you to control the system bypassing the main interface.
To enter this mode on the Xiaomi Redmi 9A, you need to turn the device off completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume.
When the Main Menu comes up with a black background and English text, the volume buttons (up/down) and the power button are the controls, and the sensor navigation is not working in this mode. You need to find the Wipe Data item and select it.
- 📱 Select Wipe All Data for a complete cleanup.
- 🔄 Confirm the action by selecting Confirm.
- ✅ The message is “Data wiped successfully».
- 🔙 Select Back to Main Menu, then Reboot -> Reboot to System.
This method is deeper and often helps solve problems that are not solved by a conventional reset via settings, but it requires caution, since random selection of the wrong item in the recovery menu can lead to undesirable consequences.
⚠️ Warning: In Recovery mode, the touch screen is not working. Use only physical volume buttons to move through the menu and the on button to confirm the choice.
What happens if the Recovery Mode does not open?
Deleting Google and Mi accounts before resetting
One of the most common problems after a reset is that the device is locked by FRP (Factory Reset Protection), a security mechanism designed to protect the owner’s data in the event of a phone theft, and if the accounts are not deleted in advance, the system will require authorization on the first run.
To delete your Google account, go to Settings -> Accounts and Sync (or simply "Accounts"). Select the email address you want and click "Delete Account." Repeat the procedure for all saved profiles.
The Mi Account is similar, but it's in Settings -> Mi Account. At the bottom of the page, you'll have the "Get Out" button. It's important to log out, not just delete the app or data, and if the phone is linked to your account, the system will alert you when you try to log out.
| Type of account | The way is on the menu | The risk of blocking | The Necessity of the Internet |
|---|---|---|---|
| Settings -> Accounts | High (FRP) | Not required for removal | |
| Mi Account | Settings -> Mi Account | High (Mi Cloud) | Required for detachment |
| Annexes (VK, FB) | Settings -> Appendices | Low. | Not required |
Ignoring this step can make the reset procedure a headache, and if you buy a used phone and see an account request that you don't know, it's almost impossible to bring the device back to life in legal ways.
Reset via computer and debugging via USB
For advanced users, there is a method of reset via a computer using the platform ADB (Android Debug Bridge), which requires the pre-activation of the developer mode on the Redmi 9A smartphone itself.
To activate debugging, go to Settings -> About Phone and quickly click on the MIUI build number seven times. You will see a message that says "You're a developer." Then, in the advanced settings, look for "Developers" and turn on the USB debugging switch.
Connect your phone to a PC with Xiaomi drivers and ADB tools installed. Open the command line on your computer and enter the command to reboot into Recovery Mode:
adb reboot recoveryOnce the command is executed, the phone will reboot itself in the Recovery menu, where you can wipe data, as described in the previous section, which is convenient if the volume buttons on the device are faulty or go off.
Data recovery after cleaning the phone
Once the Xiaomi Redmi 9A has successfully reset and the welcome screen has passed, the recovery phase begins. If you have taken care of the backup in advance, this process will take a little time, the system itself will suggest recovering data from the Mi Cloud or Google Drive cloud on the first run.
When using Mi Cloud, you just need to enter your username and password. The system will automatically upload contacts, notes, calendar entries and even the location of icons on your desktop. Photos and videos are usually restored through Google Photos, if sync was enabled.
It is important to understand that recovering deleted files that have not been backed up is almost impossible with modern methods. Recovery programs that promise miracles are in most cases fraudulent or recover only fragmented data residues.
💡
Regular automatic cloud sync is the only reliable way to ensure data is safe in case of failure or reset of a device.
Don't rush to install all the apps at once. Let the system update and stabilize completely. The first 30-60 minutes after a reset, the phone may be slower than usual, as the background indexing of files and optimization of the database.
