The decision to completely clean Xiaomi smartphone can arise in a variety of situations: you plan to sell the device, give it to relatives or just want to start with a clean slate, eliminating accumulated software debris. Regardless of the reason, the procedure requires careful attention, as it will be almost impossible to recover deleted files after cleaning correctly. Modern Android operating systems, which run the MIUI shell or HyperOS, use complex encryption algorithms, which makes the erasure process reliable, but requires preparation.
Before you start taking action, it is critical to realize that standard photo deletion or file transfer to your computer is not a complete cleanup. The data you just “erased” from the gallery stays on the disk until the system overwrites them with new information. That is why complete confidentiality requires you to perform a Hard Reset or factory reset with the device pre-prepared. In this article, we will discuss all the steps, including deleting accounts and protecting against activation blocking.
Preparing the device for complete data deletion
The first step is to back up all the important information. Even if you think there's nothing valuable on your phone, checking contacts, messaging history, and saved passwords is never superfluous. Use the built-in Mi Cloud or third-party services like Google Drive to save data. Also, be sure to export your banking application access keys and two-factor authentication, as they'll be lost once reset.
The second important aspect of the preparation is to extract the physical media. SIM-MicroSD card and memory card, if installed. Often users forget about microSD, which can store years of archival photos and documents. If the memory card remains in the device, the data on it can also be affected by the formatting process, depending on the reset option selected.
💡
Before starting the procedure, make sure that the battery charge is at least 50-60% so that the phone does not turn off at the most critical time of overwriting memory sectors.
The third point is for accounts, so that the new owner of the device does not face lockdown, you need to unplug the Mi-account and Google-account. If you do not do this, after resetting the phone will require you to enter the password from the last synchronized account, which is the standard measure of protection against theft, without a password, the device will turn into a “brick” for an outsider.
☑️ Checklist before reset
Disabling security functions and accounts
The detachment process is a critical step that many ignore, relying on automatic exit when reset. However, for security reasons, the Android system and Xiaomi shell may require password confirmation after the reset if the account was not deleted correctly in advance, a theft protection known as FRP (Factory Reset Protection).
To delete your Mi Account, go to your phone settings. Find the account section and select your profile. In the menu that opens, click "Login" or "Delete Account." The system will request a password from your Mi Account. Enter it correctly to break the connection between the device and the server. A similar procedure should be repeated for a Google account.
⚠️ Warning: If you forget your Mi Account password, restore it via i.mi.com before you start resetting.Attempting to reset a phone with an active account that has lost your password will result in a device being completely locked.
Also, check the status of the device search function, make sure the switch is in the off position, which ensures that the phone will not be listed in the cloud after erasing, and if you sell the phone, it will save the buyer from unnecessary questions and activation problems.
Resetting settings via the phone menu (standard method)
The most common and safe way to completely erase a Xiaomi phone is to use a regular settings menu, which is suitable for most users whose devices are turned on and running steadily. The interface may vary slightly depending on the version of MIUI or HyperOS, but the logic of actions remains the same.
Open the Settings app and scroll down to About. In some versions of the firmware, this section may be simply called About. Inside, look for the option "Reset" or "Format." The system will offer several options, but we're interested in deleting the data completely.
Select "Erase all data." Before the final confirmation, the phone will show you a list of what will be deleted: contacts, messages, apps, photos and settings. Carefully examine the list. If you are sure that the backup is created, click the confirmation button. The device may request a graphical key or a lock screen pin to confirm the operation.
💡
Standard resetting through settings is the mildest method that correctly completes all system processes before formatting, minimizing the risk of software errors.
Once confirmed, the cleaning process will begin. The screen will go out and the phone will reboot. You will see the Xiaomi logo and progress indicator, which can last from a few minutes to 15-20 minutes depending on the storage capacity. Don't interrupt this process and don't try to turn off the phone.
Hard Reset via Recovery Mode (for locked devices)
If the phone doesn't turn on, it's stuck on the logo, or you forget the unlock password, the standard menu method won't work, and it uses Recovery Mode, or Recovery Mode, which is a low-level interface built into the device's memory that allows you to control the system bypassing the main interface.
To enter Recovery mode on a Xiaomi phone that is off, you need to press the key combination, most often the Volume + and Power button. Hold them together until the logo appears, then release the power button, continuing to hold the volume until the menu appears.
Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select it. Next, the system can offer two options: Wipe All Data (complete erasure) or reset without deleting files (less efficient for sale). Choose a complete erasure and confirm the action by selecting Confirm.
| Resetting method | Availability | Level of difficulty | Cleaning efficiency |
|---|---|---|---|
| Through Settings. | Only when the screen is running. | Low. | Tall. |
| Recovery Mode | Even with a blocked entrance | Medium. | Tall. |
| Device search (Web) | Internet on the phone is required | Low. | Tall. |
| Fastboot + PC | In case of serious software failures | High-pitched | Maximum |
Once the cleaning process is complete in the Recovery menu, the phone will offer a reboot system. Select this item. The device will turn on as new, welcoming you to the screen of the initial language setting and Wi-Fi connection.
What happens if the Recovery Mode does not open?
Remote data deletion via Xiaomi service
There is a scenario where the phone is lost or stolen and you can't physically access it, but you want to ensure that your data doesn't fall into the wrong hands. This uses the Xiaomi Cloud web service, which only works if the device has had the Internet turned on and a Mi Account with a search function is activated.
Go to i.mi.com from any other device (computer or tablet), log in to the same Mi Account that was linked to the lost phone, and search the "Device Search" or "Find Device" section of the cloud interface.
In your list of gadgets, select the smartphone you want, and you'll have the options "Sound," "Block" and "Erase Data." Select the erasure option. The command will be sent to the phone. Once the device is online (even if it's locked), it will execute a full formatting command and delete all data.
⚠️ Warning: Remote erasure only works when there is an active internet connection on the target device. If the phone is turned off or in flight mode, the command will be executed automatically as soon as it connects to the network.
This method is also useful if you sell a phone remotely or mail it but forget to reset, but it is always better to perform a physical reset before handing over the device.
Check the results and the first steps after cleaning
Once the phone has rebooted, you'll see a welcome screen with a choice of language, which is the main indicator that the reset was successful, and if the device requires you to enter a password from a Mi Account or a Google account that you deleted earlier, then FRP protection is active and you need to enter the correct data.
Take your time to set up your phone as your primary. Go through the initial setup to your desktop, check if the gallery or files contain any residues of your data. In rare cases, file system failures may save folders but will be empty. If the data is still visible, the reset procedure should be repeated.
Now the device is ready to be transferred to a new owner or used from scratch, and for the new owner it is a guarantee that the phone does not have hidden problems with accounts, and for you - confidence in the security of personal information.
💡
The successful completion of the procedure is considered to be the appearance of a language selection screen without requesting old passwords and the absence of personal files in the device memory.
