How to format Xiaomi 8: complete system reset and cleanup

Xiaomi Mi 8, released in 2018, is still a popular device thanks to its unique design. AMOLED-But over time, the operating system becomes awash in software debris, cache files, and remnants of remote applications, leading to a marked decline in performance. In such situations, users often look for a way to format Xiaomi 8 to return the gadget factory speed and freshness.

The complete reset process, or Hard Reset, is a radical but often the only correct solution for serious software failures: it completely cleans the internal memory of the device, removing all personal data, photos, contacts and settings. Before starting the procedure, it is critical to understand that it will be impossible to recover information after formatting without a preliminary copy.

In this article, we will take a look at all the cleaning methods available, from the standard settings menu to the use of Recovery engineering mode. We will also touch on the topic of Factory Reset Protection (FRP) bypassing, which can occur after a reset if a Google account was attached to your phone.

Preparation of the device for complete reset

Before you start formatting directly, you need to do a number of preparatory steps. Ignoring this step can lead to loss of important data or problems with activating the phone after you reboot. The first step should always be to back up all the relevant information.

Sync your contacts with your Mi or Google account, save photos and videos to the cloud or to your computer. SIM-microSD card and memory card, if installed, so as not to accidentally damage the external storage file system during the process.

⚠️ Warning: Make sure the battery level is at least 50-60%. Interrupting the formatting process due to battery discharge can damage system partitions and turn the smartphone into a “brick".

Another important aspect is detachment of accounts. While modern Android can handle owner verification, pre-exit from Google and Mi Account ensures that there are no problems with blocking activation.

Method 1: Reset via MIUI settings

The easiest and safest way to format the Xiaomi Mi 8 is to use the system’s built-in menu, which does not require a computer or special skills and is suitable for most users whose phones are normally turned on and react to touch.

To start, open the settings menu and find the About Phone section. In the options list that opens, select Reset, which is usually at the bottom of the list, and the system will alert you that all data will be deleted.

Click on the button to erase all data or reset. The device can request a pattern lock, password or PIN-The screen unlock code to confirm your actions, and once confirmed, the cleanup process will begin, which will take 5 to 15 minutes.

During the procedure, the phone may reboot several times, do not interfere with the system until the screen of the initial language setting and Wi-Fi connection appears, which indicates the successful completion of the formatting.

💡

If the phone requests a password from your Mi Account when you try to reset and you don’t remember it, try to restore access via i.mi.com before starting the procedure, otherwise the reset may be blocked by the security system.

Method 2: Formatting with Recovery Mode

If the operating system is unstable, freezes on the logo or the touch screen does not respond, you need to use Recovery mode. This method allows you to perform deep cleaning of memory partitions even when the MIUI interface is not working.

To enter this mode on the Xiaomi Mi 8, turn the device off completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume.

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 Wipe Data or Clear Data. Depending on the version of Recovery, the interface can be text or graphic.

Select the Wipe All Data option and confirm the action. The system can request confirmation again by offering to select Confirm. Once the cleanup is complete, select Reboot to restart the system. The phone will be on longer than usual.

Deleting Google Account and Protecting FRP

One of the most common issues after formatting is FRP (Factory Reset Protection) locking, an Android security mechanism that requires you to enter data from a Google account that was synced to the device before resetting.

If you didn't log out of your Google account before formatting, the system will require you to enter your email and password when you first set up, and this is done to protect against theft: even after a complete reset, an attacker will not be able to use the phone without the owner's password.

If you forget your password or you buy your phone with your hands and you don't know the previous owner's data, you can't activate the device in the standard way. There are technical ways to bypass, but they require the use of a computer and special utilities to reset FRP.

For normal use, always delete your account before reset. Go to Settings → Accounts and Sync → Google, select the address you want and click Delete Account. Repeat the procedure for your Mi Account in the Mi Settings section.

⚠️ Note: Buying a used Xiaomi Mi 8, be sure to check whether the account of the previous owner is deleted. If after resetting the phone asks someone else's Google account, it will be extremely difficult to bring the device back to life legally.

Use of Fastboot and Computer

For advanced users, there is a method of formatting through Fastboot mode using a computer, which allows not only to clear the data, but also to reflash the device clean, which is useful for deep damage to the system.

You will need drivers to work. ADB/Fastboot, Mi Flash Tool or similar, as well as original USB-The phone is converted to Fastboot mode by pressing the volume and power button when switched off.

By connecting your smartphone to your PC, you can send a clearing command through the command line. This requires caution, since an error command can wipe the wrong memory partition. The main command to reset user data is:

fastboot erase userdata

This command forcibly erases the partition with user data. Once it is executed, you need to restart the device with the command fastboot reboot. The method is effective when other methods do not work, but requires the presence of a driver on the computer.

It is worth noting that for Xiaomi Mi 8 also relevant unlock bootloader (Unlock Bootloader), which is officially required to install global firmware or custom recovery. However, for simple formatting, unlocking the bootloader is not necessary.

Possible problems and solutions

Xiaomi Mi 8 users may face various difficulties in formatting, one common problem being hanging on the Mi or Android logo after a reset, which may indicate damage to system files or conflicting software versions.

If your phone is stuck in a bootloop, try re-entering Recovery mode and resetting it again.Wipe Cache sometimes helps if this option is available in your version of the recovery, although in modern versions of MIUI this section is often combined with a full reset.

Another problem is that the system refuses to accept a password or a pattern lock when trying to reset through the menu, in which case only the Recovery or Fastboot method helps. It is also possible that the touchscreen does not respond in the Recovery menu due to driver failure, then managing the volume buttons becomes the only way out.

💡

If the phone doesn’t turn on for more than 20 minutes after reset, try connecting it to the original charger and leaving it for 2-3 hours, after which try again to turn on.

In rare cases, formatting can be successful, but the phone will run slowly, often because after a reset, the system starts background indexing files and updating applications, and let the device lie on Wi-Fi for about an hour to complete all background processes.
