Modern smartphones like the Xiaomi Redmi 9A are becoming an integral part of digital life, storing a huge amount of personal information. However, over time, the device may start to work slower, there are system errors or the need to transfer the gadget to a new owner.
The procedure for resetting settings on Redmi 9A can be done in several ways depending on whether you have access to the system menu or the device is blocked. Complete data cleanup affects all user files, so before you start manipulating it is critical to understand the consequences of your actions. In this article, we will discuss in detail all available methods for restoring factory parameters.
Regardless of the method chosen, the main goal is to remove all changes made by the user or caused by software failures. Recovery Mode reset is the only way to unlock the device if you forget the pattern lock or password. Let's look at the preparatory stage, which can not be ignored.
Preparation of the device for the discharge procedure
Before you start the process of system recovery, you need to perform a number of mandatory steps to save important data. Since the procedure will delete all photos, contacts and applications, they must be copied in advance to your computer or to the cloud storage. Xiaomi users can use the service Mi Cloud or third-party solutions like Google Photos.
The second critical point is battery power: the battery must be charged at least 50-60% so that the phone does not turn off at the most inopportune time.
☑️ Checklist before reset
Also keep in mind that you can protect your Google account and Mi Account, and if you don't remember passwords from those accounts, you'd better log out before resetting through the settings menu, otherwise, after a reboot, the system may request confirmation of the owner, which is a standard anti-theft measure.
- 📱 Backup all important files and documents.
- 🔋 Check the battery level and connect the charger.
- 🔑 Remember or write down passwords from Google and Mi accounts.
- 📡 Turn off the internet if you are afraid of accidental synchronization during the process.
Reset via the settings menu (Soft Reset)
The safest and easiest way to get the Redmi 9A back to factory is to use the built-in operating system menu, which is suitable for cases where the phone is stable, but you need to clear the memory before selling or eliminate software glitches.
In the list that opens, you need to find the About phone item, which is usually at the bottom of the list. Scroll down until the Reset option appears. The system will warn you that all data will be deleted, including photos, music and installed applications.
💡
If the phone is sold, do not turn it on after the reset so that the new owner can configure the device as new.
After confirmation of action, the device may request input PIN-This is a security against accidental reset by unauthorized persons, and once you enter the data, you will start a cleanup process that will take 5 to 15 minutes depending on the amount of memory you have occupied.
⚠️ Note: Once you select "Erase all data" the process will become irreversible.
Use Recovery Mode for Hard Reset
If your smartphone doesn't load, freezes on your logo, or you've forgotten your screen password, you'll need to use Recovery Mode. This is a special diagnostic mode built into Xiaomi's firmware. To log in, you need to turn off the device completely and pinch the button combination.
On Redmi 9A, you need to press the volume button and the power button at the same time. Hold them until the Mi logo appears, then the power button can be released, while keeping the volume still. When the Main Menu menu appears, the volume buttons are controlled, and the power button is selected.
| Action. | Control button | Appointment |
|---|---|---|
| Navigation up/down | Volume +/Loudness - | Moving on the menu |
| Confirmation of choice | Power button | Entrance to the menu item |
| Getting out of the regime | Reboot | System restart |
From the menu, select Wipe Data, then confirm the choice of Wipe All Data. The system will again ask for confirmation — select Confirm. Once the cleanup is complete, the Success message will appear, and you can select Reboot to System to launch the phone.
What to do if the menu is in Chinese?
Removal of a forgotten password or pattern lock
One of the common reasons users are looking for information about a Redmi 9A reset is a forgotten lock password.Unfortunately, modern versions of Android do not allow a password to be reset without losing data for security reasons.The only way out is to completely clear the data partition.
The procedure is similar to the Recovery login described above, but if the device has been enabled with the Internet and Google account, after reset, you may need to enter a password from this account, which is a FRP (Factory Reset Protection) protection mechanism that prevents the use of stolen devices.
- 🔒 Reset will only remove the local screen lock password.
- ☁️ Google and Mi accounts will remain linked to the device on the server.
- 📞 Without passwords from accounts, it will not be possible to activate the phone after resetting.
In some cases, if the phone is not connected to the network, you can try to skip the account verification step, but in newer versions of MIUI firmware, this is extremely difficult to do.
Reset via computer and ADB (for advanced)
For users familiar with USB debugging, there is a method of resetting through the command line of the computer. This method is useful if the touch screen does not respond to presses, but the system boots, and the option of debugging over USB is enabled. You will need to install Xiaomi drivers and the ADB utility on the PC.
Connect your smartphone with a cable to your computer and open the command line in the folder with ADB. Enter the command to reboot to Restore: adb reboot recovery. After rebooting in the Recovery menu, you can clean up using ADB commands or keyboard navigation, if supported.
adb shell recovery --wipe_dataThis method avoids the use of physical buttons on the body, which is important if they malfunction. However, if the Bootloader device is locked or the system is severely damaged, the command may not execute.
⚠️ Attention: Use ADB Incorrect commands can lead to the removal of system partitions and turn the phone into a brick".
Solving problems after resetting settings
Once the Redmi 9A resets and reboots, you'll see a welcome screen, like when you first turn on a new device. The initial setup process can take some time. It's important to have a stable Wi-Fi connection to activate Google services.
Sometimes users are faced with a situation where the phone is endlessly rebooted or hangs on the logo. This may indicate damage to the system files of the firmware. In this case, a simple reset is not enough – you will need to flash the device through the computer using the Mi Flash Tool utility.
💡
If the phone doesn’t turn on for more than 15 minutes after reset, try pressing the power button for 20 seconds to force a reboot.
It’s also worth noting that the first download after Hard Reset always lasts longer than usual.The system re-indexes files and adjusts background processes, so don’t panic if the device warms or runs slowly in the first 10-20 minutes.
