How to reset all settings on Xiaomi Redmi 9

Xiaomi smartphone owners often face the need to return the device to factory status, whether due to a sale of the gadget, a sale or critical errors in the system.This process, known as Hard Reset, completely cleans internal memory by removing all user data, including photos, contacts and installed applications. For the Redmi 9 model, this procedure is standard and does not require special technical skills, if you act strictly according to the instructions.

There are several ways to do a full reset, each with its own features and scope. You can use the regular settings menu if the phone turns on and responds to touch, or you can resort to Recovery mode if the system is locked or not booting. It is important to understand that any of these actions will irreversibly delete information, so pre-setting a backup is a critical step that cannot be ignored.

In this article, we will discuss all the stages of preparation and implementation of the procedure to eliminate the risk of blocking the device with a Google account or Mi Account. We will look at the nuances of working with the MIUI shell installed on the Redmi 9, and pay attention to possible errors that can be encountered in the process.

Preparing the device for a complete data reset

Before you start cleaning, you need to make sure that the device is ready for this operation. The most important aspect is the battery charge: the charge level should be at least 50-60%. If the phone turns off due to battery discharge during the erasure, this can damage the memory partitions and turn the smartphone into a "brick" requiring flashing through the computer.

It's also critical to untie accounts that are linked to the device. Modern versions of Android and the MIUI have anti-theft protection. If you just reset your settings without logging out of your Google or Mi Account, the next time you activate your phone, you'll need to enter a password for those accounts. Without a password, you won't be able to use your smartphone.

Remember to back up your important data. You can use Mi Cloud cloud storage, Google services, or simply copy files to your computer via your computer. USB-Once reset, you can automatically recover information from the cloud, but files stored only in internal memory will be lost forever.

Resetting settings through the smartphone menu

This is the easiest and most secure method available if you know the screen unlock password and the settings menu is working correctly. First, open the Settings app on the home screen or in the notification curtain. Find a section that can be called About Phone or Advanced Settings, depending on the version of the MIUI firmware installed.

Inside the menu, you need to find Reset, the system will alert you that all data will be deleted, at which point you often need to enter a pattern lock or digital unlock code to verify the identity of the owner, a security mechanism that prevents accidental or unauthorized reset by unauthorized persons.

Once confirmed, the phone will restart and the cleaning process will begin, and the Redmi logo or Android robot animation can be displayed on the screen, which takes 5 to 15 minutes depending on the amount of memory filled, do not interrupt the device and wait for the screen of the initial setting to appear.

Hard Reset via Recovery Mode

If your smartphone doesn't turn on, you're stuck on the logo, or you've forgotten your unlock password, you'll have to use Recovery mode. This method works at the system level and allows you to reset even when the interface is broken. To enter this mode on Redmi 9, you need to turn off the device completely.

Press the Volume Up button and the Power button at the same time. Hold them until the Mi logo appears, then release the power button, but continue holding the volume button until the Recovery menu appears. This menu is controlled by volume buttons (up/down), and the choice is confirmed by the power button.

From the main menu, select Wipe Data, then Wipe All Data. The system will require confirmation, you usually need to select Confirm. After cleaning, select Reboot -> Reboot to System.

If the volume buttons on Redmi 9 don’t work well, try connecting your phone to your computer via a phone. USB-cable before you press the buttons, and in some cases, this helps you get into Recovery mode.

Delete Google and Mi Account

One of the most common problems after a reset is locking the device with FRP (Factory Reset Protection), a security mechanism that requires you to enter a password from a Google account that was synced to the phone before the reset, and if you don't remember the password, unlocking the phone will be extremely difficult.

A similar situation applies to Xiaomi account. If the device search was enabled in the settings, after reset, the phone will require authorization to Mi Account. To avoid these problems, before resetting through the settings menu, be sure to log out of accounts manually.

• 🔒 Go to Settings -> Accounts and synchronization.
• 🔒 Select a Google account and click Delete your account.
• 🔒 Select a Mi Account and exit by entering a password to confirm.
• 🔒 Make sure there are no active accounts left in the sync list.

If you reset your phone through Recovery, you can’t get around this step, so knowing passwords becomes a prerequisite for successful activation. If you buy a used device, always ask the seller to reset with you or provide login details.

What to do if Redmi 9 is not reset

Sometimes the cleaning process can end in a mistake or the phone can freeze on the logo. If the device is bootlooped endlessly after resetting, try resetting through Recovery again, paying special attention to battery power.

In some cases, it may be necessary to flash the device using a computer and the Mi Flash Tool utility.This is a more complex procedure that requires unlocking the bootloader, which can take up to 7 days of waiting after submitting an application with Xiaomi.

⚠️ Warning: If after a reset, the phone says "Device is corrupted" or suggests entering the bootloader unlock code, it means that the system files are damaged or the bootloader has been changed.

It's also worth checking the integrity of the buttons. If the volume button is stuck when pressed, the phone may constantly try to enter Recovery or Fastboot mode, ignoring normal booting, clean the buttons carefully or tap slightly on the body in the key area.

Initial adjustment after reset

Once you have successfully completed the procedure, you will see a welcome screen. Choose a language, connect to a Wi-Fi network (this will speed up the activation and verification of accounts). The system may suggest that you restore data from a Mi Cloud backup or Google - you can agree or choose to set up as a new device.

Be sure to check for system updates. Go to Settings -> About Phone and click on the MIUI version. Installing the latest security patches and bug fixes will ensure that Redmi 9 runs smoothly after cleaning.
