Xiaomi Redmi smartphones are famous for their balance between price and performance, but over time, even a reliable device can start to work slower. If your Redmi 8 is often hanging out, apps are flying out, or you just plan to sell the gadget, the only surefire solution is a complete reset to factory settings. This process, often called “zero,” returns the software part of the device to the “out of the box” state, removing all user data, accounts and files.
It is important to understand that the procedure of zeroing Xiaomi Redmi 8 is irreversible for local data. Unlike simple deletion of applications, the entire partition of user memory is erased here. That is why before any manipulations it is critical to back up photos, contacts and important documents. In this article, we will discuss in detail all available reset methods, from the standard menu to using the engineering mode, so you can choose the most suitable option for your situation.
It is worth noting that the reason for resetting is often not only software failures, but also the need to unlock the device after a forgotten pattern lock. Although modern MIUI security systems require confirmation of a Google or Mi Account account after a reset, the data cleanup process itself remains an effective way to eliminate screen locks if access to the system is partially saved or restore mode is used.
Device preparation and backup
Before you start drastic measures, make sure your Redmi 8 battery is at least 60-70% charged.The process of formatting internal memory requires stable power consumption, and suddenly turning off your smartphone at this point can damage system files.
Backup is a key step that you can't ignore. The MIUI shell has a handy tool built in to do that. Go to Settings → About Phone → Backup and Restore. Here you can choose what you want to save: contacts, messages, call log, system settings and application data.

SIM-The card will also be a useful step to not interrupt the process with incoming calls.
☑️ Checklist before reset
Method One: Resetting through system settings
The safest and easiest way to reset the Xiaomi Redmi 8 is to use the operating system’s regular menu, a method that is suitable for most users who have access to the smartphone interface and it works steadily. First, open the app menu and find the Settings icon, which is usually a gear.
In the menu that opens, scroll down to About Phone, and that's where the basic device information and system management tools are concentrated. At the bottom of the screen, you'll see Reset, and clicking on it will open a new menu with cleaning options.
The system will offer two options: Reset (without deleting files) and Erase everything (reset to factory settings). To completely reset, we need the second option. After selecting, the system will show a list of data that will be deleted, including accounts, apps and media files. Confirm the action by entering a pattern lock or PIN-code, if it is installed.
💡
Before you click the final button "Reset settings" again check that all important data is saved. Recover deleted files without professional equipment will be impossible.
Once confirmed, the smartphone will restart and start the cleaning process. The screen can go out and light up, and the Redmi logo can add a progress indicator. Don't touch the device at this point. The entire process takes 5 to 15 minutes depending on the amount of memory filled.
Hard Reset with Recovery Mode
If the phone is stuck, doesn't turn on normally, or you forget the unlock password, the only way out is to use Recovery Mode, which allows you to perform Hard Reset at the hardware level without having to use the operating system interface.
On the Redmi 8 switched off, you need to press two buttons simultaneously: Volume Up and Power. Hold them until the Mi or Android logo appears. Once the logo appears, the power button can be released, continuing to hold the volume button until the main Recovery 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. Then the system will request confirmation - select Wipe All Data. After cleaning, select Back to Main Menu, and then Reboot → Reboot to System.
| Action. | Control button | The result |
|---|---|---|
| Moving on the menu | Volume Up/Down | The cursor moves between points |
| Confirmation of choice | Power (Power) | Execution of the selected team |
| Exit from the submenu | Selection of "Back" | Back to level one |
| Reboot. | Reboot to System | Starting a cleaned system |
⚠️ Attention: In Recovery mode, the touch screen is not working, all actions are performed only with mechanical buttons on the body of the smartphone.
It's important to know that on some versions of MIUI, re-entering Recovery mode may require you to confirm your unlock password even if the phone is off. This is a security measure. If the system requests a password and you don't remember it, this method may not be available without first unlocking the bootloader via your PC.
What happens if Recovery does not open?
Deleting your Mi and Google account before resetting
One of the most common problems after resetting is activation blocking, which is FRP (Factory Reset Protection) protection, and if you add a Google account or Mi Account to your phone, after resetting, the device will require you to enter the password from the last account you used, and to avoid potential problems, you better delete your accounts in advance.
To delete your Mi Account, go to Settings → Mi Account. Find the Sign-out button at the bottom of the screen. The system will require you to enter your account password for confirmation. Similar steps should be taken for Google: Settings → Accounts and Sync → Google. Select the address you want and click Delete account.
- 🔒 Deleting accounts removes the device’s link to your profile.
- 📱 This allows the new owner to set up the phone as his own.
- 🛡️ Reduces the risk of blocking the device with security mechanisms.
If you sell a phone, it’s a must-do step: the customer won’t be able to use the device if it stays tied to your cloud, and it also ensures that your personal data synced to your account (such as notes or calendar) won’t fall into the wrong hands when you sync it again.
💡
Deleting accounts before resetting is the only way to guarantee that you will not block FRP when you transfer your device to another user.
Solution: What to do after a reset
Once the zeroing process is complete and the Xiaomi Redmi 8 has rebooted, you will see a welcome screen similar to the one you saw when you first turned on. You will have to go through the initial setting: select a language, connect to Wi-Fi and log in to accounts, at which point the system can suggest that you restore data from the backup.
If you've been backing up through MIUI tools, when you set up Wi-Fi, your phone may suggest you restore apps and settings from the cloud. Choose the right items. However, if you've been resetting your phone because of serious system errors, experts recommend not restoring old settings and apps right away.
In the first minutes of active work after a reset, the processor can work harder than usual, the system indexes files and optimizes background processes, during which the device can heat up and the battery discharge faster, this is a normal behavior that passes after 20-30 minutes of use or after one full charge.
Be sure to check for system updates. Go to Settings → About Phone → MIUI Version. Clicking on the version logo will check for new update packages. Installing the current version of the software can fix bugs that were present in the old firmware and may have caused your decision to reset.
