Xiaomi and Redmi smartphone owners are faced with the need to clean up their device of accumulated “garbage”, viruses or prepare the gadget for sale.The process, which is commonly called “reset”, technically called Hard Reset or Factory Reset. This is the procedure of completely removing user information and returning the software shell MIUI or HyperOS to the original state in which the phone left the assembly line.
Many users fear this feature as complex or risky, but a proper understanding of the mechanics of the process avoids the loss of important data. The reset affects all parts of internal memory designed to store photos, contacts, apps and account settings, while the system files and the version of the Android operating system remain unchanged unless you have flashed it.
In this article, we will discuss in detail what exactly happens to the device when this feature is activated, what are the ways to perform it and how to protect your data. You will learn about the hidden nuances of working with a Google account and Mi Account, which can lock the phone after cleaning, if you do not follow certain security rules.
Technical essence of the process of memory cleaning
When you initiate a reset, the Android operating system executes a command to erase the /data partition. This section stores all the applications installed by the user, their cache, databases, photos, music and documents. In fact, the phone does not “erase” information in the usual sense, but marks the memory cells as free to write, making old data inaccessible to the system.
The Factory Data Reset concept is being reset, which means that factory configuration files are being restored, and any changes you make to your system settings, Wi-Fi passwords, Bluetooth pairings and screen settings will be cancelled, and the device will be as clean as it was when it was first turned on.
⚠️ Warning: Once the reset process is started, it will be impossible to recover data using standard methods. Modern Android encryption protocols make files unreadable without a key that is destroyed when cleaned.
It's important to understand the difference between simply deleting files and completely resetting them. Regular deleting leaves a trace in the file system, whereas Hard Reset recreates partition structure, which is especially useful if malicious code has settled in the system that masquerades as a system process.

Preparation of the device for complete reset
Before taking decisive action, a number of preparatory steps must be taken, and ignoring this step can result in loss of access to accounts or locking the device by Google and Xiaomi, and the first step should always be to back up important data.
The second critical point is battery power: the process of formatting and reinstalling system files is energy-consuming, and if the phone turns off in the middle of the procedure, there is a high risk of damage to the bootloader or system files, which will turn the smartphone into a brick.
☑️ Checklist before reset
If you plan to sell your phone or repair it, be sure to delete your Google and Mi Account account through the settings menu before resetting, otherwise FRP (Factory Reset Protection) will work, and the new owner will not be able to activate the phone without your password.
How to run Hard Reset on Xiaomi
There are two main methods of returning to factory settings: through the operating system settings menu and through Recovery mode. The first is available if the phone turns on, the screen responds to touch, and you can get into the menu.
To reset through settings, go to Settings → About Phone → Reset. Here, the system will offer two options: Reset (saves files) and Erase all data (full reset). Choose the second option for complete cleaning. The system will request confirmation and password to unlock the screen several times.
The second method, known as Hard Reset via Recovery, is used if the phone is getting stuck, not loading, or locked with a pattern lock. To enter this mode, you need to turn off the device and pinch the combination of buttons (usually Volume up + Power). In the Recovery menu, navigation is carried out by volume buttons, and the choice is by the power button.
💡
If the touch screen is not working, use volume buttons to navigate the Recovery menu. "Wipe Data" corresponds to a full reset.
A third, less obvious way is to use the Mi Cloud service, where if the Find Device feature is enabled on the phone, you can initiate a remote reset via the browser on your computer, which is convenient in the event of a lost gadget to erase sensitive data remotely.
Account blocking risks and data protection
The most common problem after a reset is requiring you to enter a password from a previously synchronized account. Android security ties the device to the owner. If you reset your phone but didn't log out of your Google account first, the device will require you to enter a password from that email when you first try to connect to Wi-Fi.
The same thing happens with Mi Account. Xiaomi's ecosystem is tightly bound. If you turn on a cleaned phone, you'll need authorization. If you forget your password, it can take a long time to restore access and require you to contact customer support with a check to buy.
| Type of protection | When activated | Consequences of neglect |
|---|---|---|
| Google FRP | After resetting and connecting to the network | Blocking phone use |
| Mi Account | At the first boot of the system | Inability to enter the menu |
| Screen password | Immediately after inclusion (sometimes) | Requirement of the old PIN-code |
To avoid these problems, make sure to manually unwind before resetting. Go to Settings → Accounts and sync, select the right account and click “Delete Account.” Only then can you safely clean the data.
💡
Deleting your account before reset is the only guaranteed way to avoid FRP blocking and device activation issues.
What Happens to Files and Applications
Users often worry about the fate of their digital collection, completely resetting the entire contents of internal memory, including the gallery, downloads, documents and folders of messengers (WhatsApp, Telegram, Viber), the history of correspondence that is not stored in the cloud will be lost forever.
Apps downloaded from Play Market or GetApps also disappear. Once you set up your phone again, you'll have to download them from the store again. However, if you've used Google sync, the list of previously installed programs will remain in your account history, making it easier to re-install.
- 📸 Photo and video: Completely deleted from internal memory. SD and you didn't select the option to clean it, the media files on it can be saved, but it's better to extract the map before the procedure.
- 💬 Messages and calls: History SMS You'll have to use the built-in backup to save the call log. MIUI third-party.
- 🔑 Passwords and keys: All data stored in the browser and password manager will be deleted. Make sure you remember the master password or it is synced to the cloud.
Special attention should be paid to files uploaded to instant messengers. WhatsApp stores backups to Google Drive, but local databases will be destroyed. When you first install the messenger, they will offer to restore the history from the cloud - agree to return the correspondence.
Frequent errors and ways to fix them
The reset process usually goes automatically, but sometimes it fails, and one of the common mistakes is to hang on the MI or Redmi logo, which can mean that the process has been interrupted or damaged, in which case re-entering Recovery and trying to reset again helps.
Another problem is cyclic reboot: If the phone is constantly restarting after reset, there may have been an incompatible system modification or a damaged bootloader, in which case it may be necessary to flash the device through the computer using the Mi Flash Tool utility.
⚠️ Attention: Do not interrupt the reset process, even if it seems to be hanging. Progress indicator may not move for a few minutes, but the background processes are underway.
Also, users often confuse network resets with full resets. Network resets (Settings → Connection & Sharing → Wi-Fi reset...) only concern connection settings and do not delete personal files. Be careful when choosing a menu item so that you do not accidentally delete all the contents of your phone.
Recovery after cleaning
Once the procedure is completed, the phone will restart and greet you with a language selection screen, which is called the initial setup, where you will have to choose a language, connect to Wi-Fi, and log in to your Google account.
The system will offer to restore data from the backup. If you've previously done a backup on Google Drive or Mi Cloud, you can select a restore point, and contacts, calendar, notes, and even the location of icons on the desktop will return to their places.
Take your time to install all the apps at once. Let the system boot up and update Google Play services. It takes 10-15 minutes. Then you can start installing the programs and customizing the personalization, enjoying the fresh and fast Android experience.
