How to completely erase data from Xiaomi Redmi

Selling, transferring a device to another user or simply wanting to start with a clean slate are the main reasons why owners of Xiaomi smartphones are thinking about completely cleaning up memory. The process of erasing information on devices with a MIUI shell or a new HyperOS has its own nuances, ignoring which can lead to locking the gadget or leaking confidential information. It is important to understand that the usual deletion of files does not guarantee their inability to recover without special procedures.

In this article, we will discuss in detail all the steps of preparing and directly performing a factory reset. We will discuss removing Mi Account bindings, working with encrypted memory partitions and cleaning methods that are used in difficult cases.

Before embarking on radical measures, a number of preparatory steps that are often overlooked, which can turn your phone into a brick with a password request from someone else’s account, which will be a serious problem for a new owner or when reselling a device, must be taken into account.

Preparing the device for complete removal of information

The first and most critical step is to back up all the important data. Once the reset procedure is done, it will be impossible to return the information, so backup is a must. You can use cloud services like Google Drive or Mi Cloud, or save the data to an external computer.

Special attention should be paid to accounts. Android security has a theft protection mechanism that requires you to enter a password from the last used account after you reset. If you forget the login details, unlocking your phone will be extremely difficult, and sometimes impossible, without contacting customer support with purchase checks.

It’s also worth checking for two-factor authentication on important services, and make sure you have access to your phone number or backup codes, as you may need to confirm that you’re logged in to Google accounts or social media on an already cleaned device after a reset.

⚠️ Warning: Before starting the procedure, be sure to remove the microSD card if installed.The built-in reset feature sometimes offers an option to clean the external drive, but physical extraction ensures that your personal files on the card won't be accidentally wiped away.

Account unblocking and protection against blocking

The most important step that users often ignore is manually deleting accounts from system settings. Even if you do a full Hard Reset, the FRP (Factory Reset Protection) security mechanism can lock the device, requiring you to enter a password from the last synchronized Google account or Mi Account.

To properly unbundle, you need to go to the settings menu and delete all added accounts sequentially, which tells the company’s servers that the device is no longer associated with your profile, which removes the activation lock.

What is FRP and why is it important?
FRP (Factory Reset Protection) is a security system built into Android that activates when you add a Google account. If you reset with a button without deleting the account from the menu, the phone will require you to enter the password from that account when you turn it on. This is anti-theft protection, but it's a problem for those who have forgotten the password.

Let’s look at the types of accounts that require deletion:

  • πŸ“± Mi Account: The main ecosystem account that manages cloud, device search and sync.
  • πŸ“§ Google Account: Required for Play Market and most system services.
  • πŸ“± Third-party services: Samsung accounts (if services were used), social networks and instant messengers if they have system integration.

After deleting all profiles, it is recommended to restart the smartphone to make sure that the system does not ask for passwords when you log in to standard applications.

Standard reset via the settings menu

The safest and most recommended way to clean up Xiaomi Redmi is to use the system’s built-in menu, which ensures that all processes are closed correctly and that memory partitions are formatted correctly without the risk of damaging system files.

To start, go to Settings. Depending on the version of the MIUI shell or HyperOS, the path may vary slightly, but the logic remains the same. You need to find the item that is responsible for the general parameters of the device.

The algorithm of actions is as follows:

  1. Find and open the About Phone section (usually at the top of the list).
  2. Scroll down to Settings Reset or Factory Reset.
  3. At the bottom of the screen, press the button to erase all data.

The system will request confirmation of the action and possibly the introduction of a pattern lock or PIN-This is protection against accidental start of the procedure. If you want to clear the internal memory completely, make sure that the checkmark is in front of the item Clear the internal storage.

Before clicking the final β€œErase All Data” button, take a picture of a screen with important Wi-Fi settings, passwords or network-specific settings, if you haven’t synced them to the cloud.

Once confirmed, the phone will restart and begin the cleaning process, which can take anywhere from 5 to 15 minutes depending on the amount of memory filled, at which time the Mi logo or Android animations can be displayed on the screen.

Hard Reset via Recovery Mode

If the device doesn't turn on, hangs on the logo, or you forget the screen unlock password, the Recovery Mode method is used, which is more aggressive and bypasses some software locks on the interface.

To enter this mode, you need to turn off the smartphone completely. Then press the Volume+ button and the Power button at the same time. Hold them until the Mi logo appears, after which the power button can be released, while continuing to keep the volume.

In the Recovery menu, the volume buttons (up/down) control the choice, and the power button confirms the choice. You need to select a language (usually English or Chinese) and find the Wipe Data item.

Select Wipe All Data and confirm the action. The system may ask for consent several times, requiring you to press Confirm. Once the procedure is complete, select Reboot -> Reboot to System.

Cleaning of encrypted data and SD-map

Modern Xiaomi smartphones use data encryption by default, which means that even if you restore files after a reset, without a decryption key, they will be a set of useless digital noise.

If you plan to sell a memory card with your phone, it should also be cleaned. Put the card in your phone (if you took it out before), go to Settings -> The phone -> The vault, find yours. SD-map and select the formatting option.

To improve the reliability of data erasure on the internal drive, professionals recommend the following method:

  • πŸ—‘οΈ Perform a full reset to factory settings.
  • 🎬 Record a few hours of useless high-resolution video on your phone to fill up your memory before it fails.
  • πŸ”„ Repeat the reset procedure again.

This manipulation overwrites old memory sectors with new data, making it almost impossible to recover the original information even with expensive laboratory equipment.

⚠️ Note: The process of double write and reset is time-consuming and places a high strain on flash memory. Use this method only if the device contains sensitive data.

Solving problems after resetting settings

Once the data is erased and the phone is turned on, the user may encounter an activation screen. If you correctly deleted the accounts before reset, the system will simply suggest that you set the phone as new, but other situations may arise.

A common problem is that you need to enter a password from a Mi Account or a Google account that was used before. This is FRP protection. If you remember the password, just type it in. If you don't own the account (you bought the phone with your hands), you'll need to contact the previous owner.

Recovery does not remove the cloud account association, it only clears the memory.Activation block (FRP) will remain if you do not log out before reset.

In some cases, the touch screen or communication module may not work properly after reset, this is solved by rebooting or, in rare cases, flashing the device through the computer using the Mi Flash Tool utility.

It's also worth checking the date and time. Once reset, they may get lost, which will cause errors when you try to log in to Google Play or the browser. Set the current time manually or wait for sync over the network.

What if your phone asks for a password from an old Mi Account?
This means that Find Device was active, you need to enter the username and password from the account that was the last one on the device, and if you forget, try to re-establish access through i.mi.com from your computer, and without that data, you can't legally unlock your phone.
Is the information erased SIM-dump-card?
No, standard Factory Reset does not affect the data stored on the SIM-map (contacts, SMS). However, for complete confidentiality, it is recommended to remove SIM-card and, if necessary, clean it through the phone menu in the "Contact" section" -> "Management SIM".
Can I recover a photo after a Xiaomi reset?
If the phone was modern (released after 2016) and you reset through the settings menu, the data was encrypted and the encryption key was deleted, and it's impossible to recover that data at home, and in the lab, it's theoretically possible, but it's extremely expensive and difficult.
