Every Xiaomi, Redmi or Poco smartphone owner will sooner or later face a necessary but frightening procedure to completely clean the system. When the device starts running slowly, unexplained errors appear, or you just plan to sell the gadget, the question of returning to its original state comes to the fore. This operation is often called Hard Reset or factory reset, and it is one of the most powerful tools in the user's arsenal.
Many people are afraid to do this for fear of losing important photos, contacts or app settings. However, understanding the process not only prevents data loss, but also significantly extends the life of your smartphone. In this article, we will discuss in detail what exactly happens inside the MIUI or HyperOS operating system at the time of reset, and how to properly prepare for this procedure.
It's worth noting that a reset is not just about deleting files, it's about a profound overhaul of the phone's software structure: Reset deletes all user data, including Google and Mi accounts, but doesn't affect the firmware system files unless the phone has been flashed before. Understanding this subtlety is critical for those used to storing sensitive information on the device.
The essence of the process: what happens inside the system
When you initiate a reset via the settings menu or a button combination, the system runs a special script that marks all the memory parts allocated to user data as "free." Android OS stops seeing your files, although they can physically stay on the drive for some time before overwriting. This is the standard file system mechanism that ensures the speed of the process.
In parallel with cleaning the user partition, the system restores the original configuration files, and all changes you make to the network, sound, screen and application settings are replaced with default values prescribed by Xiaomi developers, which eliminates software conflicts that may have arisen as a result of installing many applications or system failures.
- 📱 Complete removal of all user-installed applications and their cache.
- 🗑️ Cleaning internal memory from photos, videos, music and documents.
- ⚙️ Return of all system settings (Wi-Fi, Bluetooth, alarm clocks) to the original state.
- 🔒 Resetting security settings, including fingerprints and facial data.
It is important to understand the difference between simply deleting files and resetting. With normal deleting, you free up space, but system debris and registry errors can remain. Factory Reset ensures that the software environment is as clean as the current firmware version allows. This is especially true after major MIUI updates, when old configs may conflict with new features.
⚠️ Warning: Resetting process is irreversible by standard system means. Once the procedure is complete, it is almost impossible to recover deleted files without special expensive equipment and skills.
Preparation of the device: critical steps
Before we start radical measures, we need to make careful preparations, and ignoring this stage can lead to loss of access to accounts or important data. The first thing to do is make sure that all valuable files are copied, and in the Xiaomi ecosystem, it is most convenient to use the Mi Cloud cloud service or third-party solutions like Google Photos.
Special attention should be paid to two-factor authentication. If you have Google or Mi Account protection enabled, after resetting, the phone will require you to enter a password from these accounts on the first activation. If you forget the password, the device can turn into a blocked access brick (FRP Lock). So make sure you remember the login details or temporarily turn off the protection.
☑️ Checklist before reset
Don't forget the battery charge. The process of formatting and reinstalling system files is energy-intensive. If the phone turns off in the middle of the procedure, it can damage the system partition and the device will stop booting. The optimal charge level is above 60%, and it is better to connect the charger during the process, if possible.
It is also recommended to detach the device from services that may block access when you change your hardware ID. For example, some banking applications or corporate profiles may require re-authorization of the device administrator.
Resetting methods: through settings and Recovery Mode
There are two main ways to get Xiaomi back to factory status: software (via menus) and hardware (via recovery menus). The first option is suitable for working phones when you can get into the interface. The second is for cases when the system does not boot, hangs on the logo or you forgot the pattern lock (although there are nuances with the key).
To perform the reset, go to Settings → About Phone → Reset. Here, the system will offer two options: Reset (only parameters) and Erase all data (full reset). Choose the second option for complete cleaning. The system will warn you about the consequences several times and ask you to enter the password unlock the screen.
If the phone is not turning on normally, Recovery mode is used. To log in on most Xiaomi models, you need to turn off the device and press the Volume Up + Power buttons simultaneously. In the menu that appears (often in English), you need to select Wipe Data, then Wipe All Data. Navigation is done with volume buttons, the choice is the power button.
| Method | When to use | Difficulty | Risks. |
|---|---|---|---|
| Through Settings. | The phone is working normally and has access to the menu. | Low. | Minimum |
| Recovery Mode | The system is not loaded, there are freezes. | Medium | Mistake in choosing a menu item |
| Through the Mi PC Suite | The phone is determined by the computer, but it doesn't work. | Tall. | Requires drivers and PCs |
| Fastboot (MiFlash) | Full flashing, major failures | Very high. | Possible loss of warranty |
And there's also the Fastboot mode, which is used for deep flashing through the computer, which is not really resetting, but rather reinstalling the operating system from scratch, which requires a computer, a USB cable, and a special utility called the Mi Flash Tool, which is effective at critical system errors, but requires caution.

Resetting: What will change in the phone
Once you've completed the procedure, you'll see a welcome screen, like when you first turn on a new smartphone, which means Factory Reset has been successful, the phone will run faster, the extra files and cache that could have taken up gigabytes of memory will disappear, but your personalizations will also disappear with the garbage.
The first turn on after the reset takes longer than usual, the system re-optimizes applications and creates the necessary configuration files, during which time the phone can significantly heat up — this is a normal processor, do not panic. Give the device 15-20 minutes to stabilize.
- 🚀 Significant increase in free RAM and permanent memory.
- 🔋 Improved autonomy by removing background parasite processes.
- 🆕 Return of all icons, widgets and desktop design to the standard look.
- 📉 Disappearance of accumulated errors in the sensor and wireless modules.
However, if the phone was caused by a hardware malfunction (such as a dying battery or a motherboard defect), reset will not help. In such cases, software purity does not affect the physical condition of the components. If the phone is heated to a simple or quickly discharged, you should consider a diagnosis at the service center.
⚠️ Warning: After a reset, antivirus and banking applications may not work properly until you have fully checked the system and reauthorized.
💡
After reset, don't install all the apps at once. Put 2-3 main ones and use your phone for an hour, which will help you to understand whether the problem has disappeared, or whether a particular application is to blame.
Problems after discharge and ways to solve them
Even a properly executed reset can run into contingencies, and one of the most common problems is a Google account lock (FRP) that requires you to enter a password from an account that was synced to the phone before the reset, and it's designed to protect you from theft: if a thief steals a phone and dumps it, he won't be able to use it.
