Situations when you need to completely clean the memory of a smartphone, arise for every Xiaomi owner regardless of the device model, this can be due to the sale of a gadget, the need to eliminate software errors, or simply the desire to return the system to its original speed. Before formatting a phone, it is important to understand that this process irreversibly deletes all personal data, so preparation is a critical step.
The reset procedure on devices with a MIUI shell or a new HyperOS has its own features that distinguish it from pure Android. Modern security algorithms require additional actions, such as untying a cloud account, without which the device can lock. In this article, we will discuss in detail all the stages of preparation and the formatting process itself by various methods.
Don't be afraid of the word formatting, because in a smartphone context, it's a standard factory repair operation, but carelessness in the steps can lead to the loss of important contacts or photos, and we'll look at proven ways to avoid typical errors and successfully complete a system cleanup.
Preparation of the device for complete reset
The first and most important step before any manipulation of system files is to create a backup. Even if you plan to sell a phone, a copy of the data will quickly transfer information to a new device. Xiaomi owners have several ways to save data, including cloud storage and local copying to the computer.
Be sure to check your sync status with your Google and Mi Account. Make sure your contacts, notes and calendar are uploaded to the servers. If you forget to untie your Mi Account before resetting, the next time you activate, the phone will require a password from the old owner, which is a serious security issue.
- 📸 Backup photos and videos to Google Photos or your computer.
- 📞 Export contacts to.vcf or make sure they are synchronized.
- 🔑 Write down passwords from important apps that don’t automatically recover.
- 🔋 Charge the battery of the smartphone to a minimum 50-60% Uninterrupted process.
It is also recommended to remove the memory card. SD and SIM-Although modern systems try not to affect external drives when reset, physical extraction of the card guarantees the safety of the data on it.
☑️ Readiness for formatting
Standard reset via the settings menu
The most secure and recommended formatting method is available directly from the operating system interface. This method is suitable for most cases when the phone turns on and responds to commands. To start, go to Settings, then select About Phone or Advanced Settings depending on the shell version.
Next, you need to find the Reset section. In new versions of HyperOS, the path may be slightly different, but the logic remains the same. The system will offer two options: reset only settings or completely delete all data. For formatting, we need the second option, which is often referred to as Erase all data.
⚠️ Note: After confirmation, the system may request a pattern lock or PIN-The screen unlock code is a measure of protection against inadvertent deletion of data by unauthorized persons.
The process takes 5 to 15 minutes, depending on the amount of memory you have filled and the speed of your Xiaomi CPU. While you're running, the phone can reboot several times, and the screen will display the brand logo or download animation.
What to do if the reset button is inactive?
Formatting through Recovery Mode
If the operating system is not booting or the touch screen is not responding, Recovery mode is used. This is a special diagnostic interface built into the phone's memory that allows you to perform low-level operations. To enter this mode on the phone that is turned off, you need to pinch the key combination.
Usually, a combination of Volume Up and Power buttons is used. Hold them together until the Mi logo appears, then release the power button, while continuing to keep the volume. The menu uses volume buttons and power buttons to navigate.
From the Recovery menu, select a language (if available) and go to Wipe Data. The system will warn you of the risks of data loss. Confirm the action by selecting Wipe All Data. After the process is complete, select Reboot to restart the device in normal mode.
| Action. | Navigation button | Selection button |
|---|---|---|
| Up/down movement | Volume +/- | - |
| Confirmation of choice | - | Power (Power) |
| Entrance to Recovery | Volume + and Nutrition | Hold it together. |
| Exit/Reset | Volume +/- | Meals (on Reboot) |
💡
If the Recovery menu does not appear with the standard combination, try connecting the phone to your computer via a computer. USB-cable before buttons are pressed, and on some models, it's a prerequisite for resetting.
Deleting your Mi and Google account before resetting
One of the most common problems after formatting is activation blocking, which is an Anti-Theft security mechanism that prevents the use of a stolen device, so if a Mi or Google account is entered on a phone, the system remembers its association with a specific serial number of the device.
To avoid blocking, you need to manually log out of all accounts before resetting. Go to settings, find Accounts and Sync. Select Mi Account and click Leave or Delete Account. Repeat the same procedure for Google account.
If you forget your account password, restore access in advance via your computer or other device. Trying to bypass the lock after a reset is more difficult and often requires contacting the service center with a check of purchase. Untie accounts is the only guaranteed way to avoid activation problems.
⚠️ Warning: Simply removing an app or clearing Google Play data does not untie your device from your account.
Solving problems in formatting
During the reset process, users may encounter various errors, such as the phone may freeze during the data cleaning phase or restart indefinitely, often due to damage to system files or a lack of battery power at a critical time.
If the device has been stuck on the logo for more than 20 minutes, try to perform a forced reboot by holding the power button for 10-15 seconds. If the problem persists, you may need to flash the device through the computer using the Mi Flash Tool utility. However, this is a more complex procedure that requires an unlocked bootloader.
- 🔄 When you hang, try to clamp down the Power. + Volume Down for 10 seconds.
- 🔌 Make sure the original cable is working if you connect to a PC.
- 🔋 Leave your phone on charge for a few hours if the battery has been deeply drained.
Sometimes, after a reset, the touch screen may not work properly or the calibration will go wrong, and then re-resetting or calibrating through the engineering menu helps, although modern Xiaomi often has no access to it. If the problems are hardware-related, reset software will not solve them.
💡
If the phone continues to function unstable after reset, the problem may lie in the physical wear and tear of the memory storage or battery, not in the software.
