Many budget smartphone owners face the challenge of getting the device back to its original state. Xiaomi Redmi 9A is no exception, and over time the operating system may start to run unstable. Often the cause is accumulated software debris, application conflicts or errors after a failed update, in such situations, the only right solution is a complete return to factory parameters.
Memory and settings cleaning may be required before selling or transferring the gadget to another user, and it is important to understand that this process will irreversibly delete all personal information stored in internal memory, which is why you need to be carefully prepared before any manipulations begin to avoid losing important data and problems with further activation of the device.
In this guide, we will take a look at all the options available, including options for cases when the phone is not turned on or locked, you will learn about the nuances of working with the MIUI shell, the features of deleting a Google account and methods of resuscitating the system through Recovery mode. Following the instructions will help to safely complete the procedure even for a beginner.
Preparation of the device for complete reset
The first step is to save all the important data, because once you start the procedure, it will not be possible to restore it using standard means. You can use Google Drive cloud storage, Mi Cloud’s built-in sync function, or transfer files to your computer via a computer. USB-cable.
Special attention should be paid to battery charge. The battery must be charged at least 50-60% to prevent the sudden shutdown of the smartphone at a critical time of overwriting system files. If the device runs out during formatting, there is a high risk of damage to the bootloader, which will turn the phone into a "brick".
You also need to unplug your accounts to avoid blocking activation, and if you haven't logged out of your Google and Mi Account profiles before resetting, the system will require you to enter your password when you first turn them on, which is a security mechanism against theft, which can be a problem if you forget your login details.
☑️ Checklist before reset
- 📱 Check the battery level and connect the charger if necessary.
- 💾 Copy all important files to external media or to the cloud.
- 🔒 Remember passwords from accounts tied to a smartphone.
- 📶 Remove the microSD card so you don’t format it accidentally.
💡
Before resetting, be sure to remove SIM-Although it will not affect system files, it will eliminate the risk of accidentally deleting the contacts stored on the SIM if they are not synchronized with the cloud.
Reset Xiaomi 9A through system settings
The simplest and most secure method is available directly from the operating system that is running, and it works for most cases where the interface responds to commands and menus are available. First, go to the main menu and select Settings.
In the options list that opens, you'll find the About Phone section, which is usually at the bottom. Scroll down until the Reset line appears. When you click on it, you'll see two options: reset all settings (Wi-Fi, Bluetooth) and delete all data. You'll choose the second option: Erase all content.
The system will warn you that all files will be deleted, and if you have attached a Mi Account, you will need to enter a password from it to confirm the operation, a security measure that prevents remote theft of data, and after entering the password and confirming the phone will restart and begin the cleanup process.
The duration of the process depends on the amount of memory filled. On models with a lot of data, it can take from 5 to 15 minutes. The screen can go out and turn on several times - this is normal behavior of the system when reinstalling components.
Hardware reset via Recovery Mode
If the phone is stuck, does not load to the desktop or forgotten the pattern lock, use Recovery mode. To enter it, you need to completely turn off the smartphone. After turning off, press the volume button and the power button at the same time.
Hold both keys until the Redmi or Mi logo appears, then release the power button, keep the volume up. In a few seconds, the Recovery menu will open. The volume buttons (up/down) control the menu, and the power button confirms the choice.
From the menu, select Wipe Data, then Wipe All Data. The system will ask for confirmation — select Confirm. Once you have cleaned, Data wiped successfully will appear. Select Back to Main Menu and then Reboot —> Reboot to System.
What happens if Recovery does not open?
- 🔘 Hold the volume up. + Power on the device switched off.
- 📉 Use volume buttons to navigate the Recovery menu.
- ✅ Confirmation of choice is made by a short press of the power button.
It's important to keep the process running even if it looks like the phone is getting stuck. The boot indicator may not show up, but the memory sectors are recorded in the background. The power interruption at this point is critical to firmware integrity.
Deleting Google and Mi accounts before resetting
Xiaomi's current smartphones are heavily protected, and if you activate a Google account, it will request a username and password after reset, which is FRP (Factory Reset Protection), and Mi Cloud protection works the same way, without unlocking it, it will turn into a useless piece of plastic.
To avoid problems, go to Accounts and Sync before resetting, select Google account and click Delete account. Repeat the procedure for Mi Account. Only then can you clean the data.
If you have already reset your phone and forgotten your password, it will be extremely difficult to restore access, officially only through a Google account recovery form or a device purchase check at a service center to unblock Mi. Third-party bypassing methods are often fraud.
💡
Unbinding accounts before resetting is the only guaranteed way to avoid FRP after rebooting.
Table: Comparison of discharge methods
Different situations require different approaches, and below is a comparison of methods so that you can choose the best one for your case.
| Parameter | Through Settings. | Through Recovery. | Through the Mi Cloud |
|---|---|---|---|
| Access to the menu | Required. | Not required | Internet is required |
| Data retention | Complete removal | Complete removal | Remote removal |
| Difficulty | Low. | Medium | Tall. |
| Implementation time | 10-15 minutes. | 5-10 minutes | Depends on the network. |
The Mi Cloud method is useful if the phone is lost or stolen, and when you access a website from a computer, you can send a remote cleanup command, but if the device is not connected to the Internet, the command will only be executed after it appears on the network.
Possible problems and solutions
Redmi 9A owners may experience a situation where the phone restarts indefinitely or hangs on the logo after a reset, often because of damage to the system partition or incompatibility of the residual files.
In this case, you may need to flash the device through your computer using the Mi Flash Tool utility, which is a more complex procedure that requires an unlocked bootloader. If you are not sure about yourself, you should contact the service center.
⚠️ Note: If after resetting the phone requires an unlock code that you did not install, it may have been stolen or previously belonged to another person.
Another common problem is formatting error: If the process is stuck at a certain percentage and does not move for more than an hour, try forcibly restart the device (clamp the power for 15 seconds) and repeat the procedure through Recovery.
Why does the phone warm up after a reset?
- 🔥 Heating in the first hour of operation is a sign of normal system optimization.
- 🔄 Infinite reboot may require flashing over PC.
- 🔒 Requesting a password after reset - the regular work of the protection FRP.
