Sometimes users are faced with a situation where the smartphone begins to work unstable, freeze or lock forgotten pattern lock. Owners of the popular Xiaomi Redmi 9 model are no exception and often look for ways to return the device to its original state.
This process may be necessary not only for performance issues, but also before selling a gadget to ensure complete confidentiality of personal information. It is important to understand that returning to factory settings is a radical measure that will irrevocably destroy all files, photos and contacts stored in internal memory, so before starting any action you need to carefully prepare and weigh all the pros and cons.
In this article, we will discuss in detail two main methods of resetting: through the system settings menu if you have access to the phone, and through Recovery mode if the device is locked or not loading. Careful follow the instructions will help you avoid errors and successfully resuscitate your Redmi 9 without having to contact the service center.
Preparation of the smartphone for the procedure of resetting
Before you start taking action, you have to take a number of preparatory steps to keep your data safe and keep the process going, and the most critical task is to back up all the important information, and you can use the built-in MIUI tools, Google cloud services, or third-party backup apps.
Be sure to check the battery's charge level.The process of formatting internal memory and reinstalling system files can take 10 to 30 minutes, and a sudden power outage at this point can lead to serious software failures. Charge the device to a minimum of 60-70% to have power reserve.
It's also important to make sure you remember your Mi Account and your Google account. Once reset, the security system will require you to enter a username and password to verify ownership of the device, and if you forget that information, unlocking the phone will be extremely difficult or impossible without proof of purchase.
☑️ Checklist before reset
It is not superfluous to remove the microSD memory card and SIM-A card before the procedure begins, although modern versions of Android usually ask for proof of erasure. SD-physical extraction of the media completely eliminates the risk of accidental removal of important files from external storage.
Method 1: Reset via the system settings menu
If your Xiaomi Redmi 9 is functioning normally, the screen is touch-sensitive, and you can unlock the device, then this method is the most preferred. It is safe, easy to execute and minimizes the risk of errors. First, go to the main app menu and find the Settings icon.
In the options list that opens, scroll down to the About Phone section, where you can find basic information about the model, MIUI and Android versions, as well as memory management tools. Click on this to go inside the menu.
At the bottom of the screen, you'll see the Reset button, and if you click on it, the system will offer two options: Reset all settings (return only system settings, saving files) and Erase all data (full Hard Reset).
💡
Before clicking the “Erase All Data” button, take screenshots of important Wi-Fi and Bluetooth settings to restore the connection faster after the reboot.
Once you select the deletion option, the system will ask you to enter a pattern lock or a screen unlock pin to confirm the operation, which is a safety mechanism against random actions, then the final warning that all data will be deleted, confirm the action, and the cleanup process will begin.
The device will reboot, and the Redmi logo with the progress indicator may appear on the screen. At this time, you can not touch the phone. After the procedure is completed, you will see a welcome screen, as when you first turn on a new smartphone.
Method 2: Hard Reset with Recovery Mode
If the phone is locked, hangs on the logo or does not respond to touch input, the only option is to use Recovery Mode, which allows you to perform a deep reset at the hardware level, ignoring the state of the operating system1.
Press both the volume button and the power button at the same time. Hold them until the Mi logo appears, after which the power button can be released, while continuing to hold the volume rocker. In a few seconds, the Recovery menu will open with a black background and colored lines.
Navigation in this menu is done by the volume buttons (up and down), and the choice of item is made by the power button. You need to find the line "Wipe Data" and select it. In the next menu, confirm the choice by clicking "Wipe All Data".
⚠️ Warning: In Recovery mode, the touch screen is not working. All actions are performed exclusively with mechanical buttons, so be careful when navigating, so as not to select the wrong item.
The system will request final confirmation of the operation. Select "Confirm" and wait until the process is completed. It usually takes less than a minute. After a successful reset, the message "Data wiped successfully" will appear. Click "Back to Main Menu" and then select "Reboot" -> "Reboot to System".
What happens if Recovery does not open?
Bypassing the blocking of Google account (FRP)
Modern Android smartphones are equipped with FRP (Factory Reset Protection) protection, which is automatically activated when a Google account is linked and is designed to protect data in the event of a theft or loss of the device. Once a reset is performed, even through Recovery, the phone will require you to enter a password from the last used Google account.
This means that if you sell a phone or give it to another person, the new owner will not be able to use it without your credentials, so before selling, be sure to log out of all accounts through the settings. If you reset your personal Redmi 9, just enter your username and password when you first set up.
If you forget the password from the Google account, the restoration of access is possible only through the procedure of restoring an account on another device (computer or tablet) via the link accounts.google.com. Without this, it will not be possible to unlock the phone in a legal way.
💡
The FRP system locks the device after a reset, requiring a password from a Google account that was synced before the reset – this is the main protection against theft.
Common mistakes and ways to solve them
Xiaomi Redmi 9 users may face various difficulties in resetting, and one common problem is “bootloop” when the phone is constantly restarting and unable to start the system, which may indicate that system files are damaged or there is not enough space for temporary files when upgrading.
Another common mistake is not being able to log into the Recovery menu, and users often confuse the length of time they press buttons, some versions of MIUI require short-term pressing, others require long-term holding until they vibrate, and the problem may be sticking volume buttons.
| Problem. | Possible cause | Decision |
|---|---|---|
| The phone will not turn on after resetting | Battery discharged or software failure | Put on charging for 1 hour, then try to turn on |
| Forgotten Mi-account | No record of data | Recovery via Mi Account website with a check of purchase |
| Sensor doesn't work in Recovery | Features of the recovery regime | Use volume and power buttons for navigation |
| FRP request appears | Protecting Google | Enter the account data used before the reset |
If the phone gets hot or discharges quickly after reset, let it run quietly for about an hour, index files and optimize applications in the background, which puts a strain on the processor, and usually after 30-60 minutes, the temperature returns to normal.
Xiaomi Redmi 9 setup after reset
After a successful reboot, you'll see a welcome screen. Select the interface language and connect to the Wi-Fi network. This is a must-have step to activate the device and check for security updates. The system may suggest upgrading to the latest version of MIUI, which is recommended for stable operation.
You'll then sign in to your Mi Account and Google account, and if you're planning to use cloud services, you'll need to enter the same data you used to sync your contacts, notes, and calendar, and if you don't need your accounts, you can skip that step by creating a local profile.
When you set up your lock screen, create a new pattern lock or pin, remember to write it down or remember it securely, as it will protect your data in the future, and the system will also suggest setting up your fingerprint and facial recognition for quick access.
Finally, install the apps you need from the Google Play Market, and since all data has been deleted, you will need to re-download instant messengers, social networks, and banking apps, and you should set up your backup immediately so that future recovery can be automatic.
⚠️ Warning: After the first turn on, don't install all the applications en masse. 10-15 minutes to stabilize processes, otherwise overheating and interface lags may occur.
