How to completely clean Xiaomi of everything: from resetting to deep memory cleaning

Xiaomi smartphones running on the shell of MIUI or HyperOS have powerful functionality, but over time the system becomes accreted with digital garbage: it can be the remnants of remote applications, cache of Google services, temporary update files or just personal data that must be hidden before selling the device. Users often wonder how to clean up the xiaomi of everything to return the gadget to factory speed or ensure privacy.

The process of complete cleaning is not limited to simply removing photos from the gallery. Deep cleaning involves working with system partitions, resetting accounts and, in some cases, flashing the device. In this article, we will discuss all available methods, from standard reset through menus to using engineering commands and ADB. It is important to understand the difference between conventional formatting and full wiping of data.

Before we start taking drastic measures, we need to assess the current state of the system. Often users confuse memory shortages with system errors. Complete cleaning of the UserData partition deletes absolutely all files without the possibility of recovery through the Recycle Bin. Therefore, preparation for the procedure is a critical step that can not be ignored even in a hurry.

Preparing the device for complete data deletion

We should start with backup. There are several layers of data storage in the Xiaomi ecosystem. Local backup allows you to save settings and applications, but it takes up space in internal memory, which we're just going to clean up, so using cloud services or external storage becomes a requirement.

Be sure to untie your accounts. If your device has Mi Account or Google Account activated, your phone will ask for a password from them (FRP — Factory Reset Protection) after the reset. Without that data, the smartphone will become a “brick” for the new owner. Check the activation status in the settings menu.

• 📱 Backup your contacts and photos in Google Photos or on your computer.
• 🔐 Write down passwords from all associated accounts (Mi, Google, social networks).
• 💳 Extract. SIM-MicroSD card and memory card before the start of the procedure.
• 🔋 Charge the battery to at least 60% so that the process does not interrupt.

⚠️ Note: Deleting your Google or Mi Account immediately before resetting in some firmware versions may not remove the lock. FRP I'd rather do the decoupling. 10-15 minutes before the cleaning procedure.

Standard reset to factory settings via menu

The safest and most common way to clean up Xiaomi is to use the built-in functionality of the system, which is suitable for most users who want to sell a phone or fix software glitches, the process affects the user partition and returns system settings to the “out of the box” state.

To start the procedure, go to Settings → About Phone → Reset. Here, the system will offer two options: Reset (without deleting files) and Erase all data. We are interested in the second item. Once confirmed, the system will require you to enter a pattern lock or a screen unlock password.

It's important to note that a standard reset doesn't always delete data permanently in a forensic context, but for household use, it's enough. Data is marked as free space but physically stays on the drive until it's overwritten. However, MIUI and HyperOS have encryption algorithms in place, making it extremely difficult to recover data after the reset.

💡

If the phone is stuck in the reset phase, don't panic. Wait for the battery to run out completely, then charge the device for 30 minutes without turning on, and then try to start it again.

Cleaning through Recovery (Hard Reset)

If the system doesn’t boot or the touch screen doesn’t respond, Xiaomi can be cleaned through Recovery Mode, a low-level interface that works independently of the main operating system and is accessed by a combination of physical buttons.

Turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi or Redmi logo appears. In the Recovery menu, the navigation is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item.

Inside the cleaning menu, you will be asked to select Wipe All Data. Confirm the action by selecting Confirm. The system will warn you of the irreversibility of the process. Once you have cleaned, select Reboot to restart. The device will be on longer than usual, as the initial file system configuration takes place.

Deep cleaning via Fastboot and computer

For advanced users who want to clean everything as thoroughly as possible, including system debris that is not removed by standard methods, there is a Fastboot mode, USB-cable ADB/Fastboot. It allows you to format sections directly.

Put your smartphone into Fastboot mode by pressing the volume button when you connect the cable to the phone that is turned off. The screen will show an image of a rabbit repairing an android. On your computer, you need to open the command line in the folder with the ADB tools. To check the connection, enter the command:

fastboot devices

If the device is determined, you can clean specific partitions. The fastboot erase userdata command will completely destroy user data. The more radical fastboot erase cache team will clear the system cache. Be extremely careful: the fastboot erase boot team will make the phone non-functional without further flashing.

• 🖥️ Install Xiaomi drivers USB Driver on the computer.
• 🔌 Use original or quality cable for stable connection.
• ⚡ Do not turn off the device while executing commands in the console.

⚠️ Note: Using Fastboot commands to erase system or vendor partitions without having a ready-made firmware to restore will cause the device to fail completely (Hard Brick).

Removal of hidden debris and residual files

Even after resetting, if you haven’t done a full flash, there may be traces of previous activity in your memory, especially if encryption was used, and it’s worth checking before selling if there are any files left in hidden folders that some applications create, bypassing the standard structure.

Use the built-in Security app from Xiaomi. Go to Cleanup and run the scan. The system will find cache, advertising files and remnants of deleted files. APK-For a deeper analysis, you can connect your phone to your PC in file transfer mode (MTP) and manually check the folder Android/data and Android/obb.

Pay special attention to the MIUI folder at the root of the internal drive. It often stores voice logs, screenshots of remote applications and temporary photo editing files. The Mi File Manager hides some system folders by default, so it is better to use a PC or third-party root file managers (if any) for complete cleanup.

💡

Manually checking Android/data and MIUI folders allows you to remove up to 2-3 GB of hidden debris that is not visible in standard memory analysis.

Frequent questions and problems with cleaning

The process of deleting data completely often causes users to worry about the risk of losing important information or locking the device. Below are answers to the most common questions that will help avoid critical errors. If you doubt your actions, it is better to stop at a standard reset via the menu.

One of the biggest problems is blocking Mi Account. Many people forget that the linked account is a protection against theft. Once cleaned, the phone will require authorization. If you forget your password, restore it through i.mi.com before you start resetting. It is also worth turning off Find Device in the cloud settings.
