The situation when a user forgets the pattern key or digital PIN code on his smartphone is one of the most common problems in the Android ecosystem. Owners of the popular model Redmi 9 are no exception, since the interface MIUI has its own specific security features. Attempts to enter incorrect combinations repeatedly lead to a complete blocking of the device, making it an almost useless piece of plastic and glass.
Fortunately, engineers Xiaomi have provided several mechanisms for restoring access, which range from soft methods through cloud services to a radical complete reset of settings. The choice of a specific method depends on whether you have previously logged in Mi Account, whether USB debugging is activated and whether you have access to the Internet. It is important to understand that most effective methods entail complete loss of user data, so you need to approach the process consciously.
This guide describes in detail all the current options for solving the problem for the model Redmi 9. We will look at both standard system tools and methods of forcing a reboot into recovery mode. Before starting any manipulations, make sure that the device is charged at least 50% to avoid a sudden power outage at a critical moment of firmware or formatting.
Using the Mi Cloud service for remote unlocking
The most gentle method, which in some cases allows you to save data, is to use the manufacturer's cloud service. If the locked Redmi 9 has been logged in Mi Account and the “Find my device” function has been enabled, you can try to unlock the screen remotely. This method only works if there is an active Internet connection on the smartphone, be it a mobile network or Wi-Fi.
To start the procedure, you need to go to the official portal mi.com from any other device, be it a computer or another phone. Enter your credentials that were used on the locked gadget. The system will automatically detect your location Redmi 9 and offer a list of available actions. Among them there will be an option to lock or unlock the screen, which will overwrite the current security code with a new one.
⚠️ Attention: The remote unlock function via Mi Cloud is unstable on new versions of MIUI 12 firmware and higher due to enhanced Google security policies. If the unlock button is inactive, this method unfortunately will not work.
After sending the command to the device, it may take some time to sync. As soon as the command is completed, the old pattern or password will be erased, and you will be able to log in using the new code specified through the web interface, or simply by swiping if the system allows. However, it is worth remembering that FRP Lock (Factory Reset Protection) may require you to enter your account password after a reboot.
If you have two-factor authentication enabled in your Mi Account, make sure that you have access to the linked phone number or backup codes to log into the cloud service.
Reset settings via Recovery (Hard Reset) mode
If cloud methods are not available, the only working option is a forced reset via the recovery menu. This process completely deletes all data from the phone's internal memory, including photos, contacts, and installed applications. To enter the mode Recovery on Redmi 9 you need to perform a certain sequence of actions with physical buttons.
Turn off the smartphone completely and wait until the screen vibrates or goes out. Then hold down the Volume Up button and the Power button at the same time. Hold them until the logo Miappears, then release the power button, but continue to hold the volume button until the main recovery menu appears. Navigation in this menu is carried out using the volume buttons, and selecting an item is done using the power button.
☑️ Algorithm for entering Recovery
In the menu that appears, select item Wipe Data, confirm the action and wait until the formatting process is completed. After successful completion, the system will prompt you to reboot the device by selecting Reboot. The first boot after a reset will take longer than usual, since the system will recreate the file structure.
| Action | Navigation buttons | Result |
|---|---|---|
| Enter menu | Volume Up + Power | Start Recovery mode |
| Move through items | Volume Up / Down | Select the desired line |
| Confirm selection | Button Power | Run command |
| Exit mode | Select Reboot | Reboot the system |
What to do if the menu does not appear?
Sometimes entry into Recovery is blocked fast loading. Try connecting the switched off phone to the computer with a USB cable, and then holding down the button combination. This can force the device into the desired mode.
Bypassing protection through the Google Find My Device service
An alternative option for devices with a tethered Google Account is to use the “Find Device” service from the search giant. This method also requires the Internet to be blocked Redmi 9. The principle of operation is similar to the method from Xiaomi, but uses the Google infrastructure to manage the device.
Go to the website android.com/find and log in using the account that was the main one on the phone. If the system sees your device online, you will have the option to “Clean device”. Pressing this button initiates a remote_factory reset_, which will delete the screen lock password along with all data.
It is worth noting that after this procedure the protection will work. FRP. When setting up for the first time, the phone will require you to enter the username and password for the same Google account that was synchronized before the reset. This is done to protect against theft, so you won’t be able to use the phone without knowing this data.
Remote wipe via Google works more reliably than via Mi Cloud, but guarantees 100% data loss and mandatory account verification when turned on.
Unlocking via computer and ADB (for advanced)
For users who have previously included USB debugging in the menu for developers, it is possible to remove the lock without losing data using a computer and tools ADB (Android Debug Bridge). This method requires installed drivers and minimal knowledge of working with the command line.
Connect Redmi 9 to the PC via the original cable. Open a command prompt on your computer in the folder where ADB is installed and enter the command to test the connection. If the device is authorized, you will see its serial number in the list. Next, you need to run the command to delete the file that stores the access keys.
adb shell rm /data/system/gesture.keyAfter running the command, restart the phone. In some versions of Android, this allows you to log in without a password, after which it is recommended to immediately install a new security method. However, on modern versions MIUI with stronger encryption, this method is often ineffective, since the keys are stored in an encrypted partition.
⚠️ Attention: This method will only work if you have previously confirmed USB debugging on this computer. If the confirmation window did not appear earlier, the computer will not gain access to the file system.
FRP protection problem and ways to solve it
Factory Reset Protection (FRP) is a security mechanism that is activated automatically when resetting settings through the Recovery menu. Its purpose is to prevent unauthorized persons from using a stolen phone. After formatting Redmi 9 the system will require you to confirm the owner’s identity by entering the Google or Mi account data that was synchronized earlier.
If you remember your account details, there will be no problems. You just need to enter your email and password during the initial setup. However, if you forget this data, the device turns into a “brick” from the point of view of the average user. You can officially restore access only through the Google account recovery form on another device.
There are many unofficial methods for bypassing FRP, including the use of special utilities like Mi Flash Unlock or exploits through the browser. These methods are constantly changing as the manufacturer patches vulnerabilities in security updates. Using such methods may lead to a violation of the warranty.
Preventing blocking and creating backups
To avoid a stressful situation in the future, it is recommended to set up data backup to the cloud. On Redmi 9 this can be done through settings Mi Cloud or Google Drive. Regular synchronization of contacts, photos and notes will allow you not to worry about losing information if you are forced to reset your password.
It is also advisable to write down your PIN code or draw a pattern on paper and store it in a safe place, separate from your phone. Biometric methods such as fingerprint or face unlock are convenient, but they do not replace the main password, which still needs to be entered periodically.
⚠️ Attention: MIUI interface is updated regularly. The location of menu items and function names may differ depending on the firmware version (Global, China, EEA). Always check your device's up-to-date interface.
Set up Smart Unlock via your Mi Band or trusted locations to reduce the need to enter a complex password in a secure environment.
Frequently asked questions
Will resetting the password remove all photos from phone?
Yes, in 99% of cases, resetting the password via Recovery Mode or Find My Device leads to complete formatting of the internal memory. Photos taken with the camera and saved in the device’s memory will be lost forever if they were not synchronized with the cloud.
Is it possible to unlock Redmi 9 without data loss?
You can unlock the phone without data loss only if the remote command via Mi Cloud works (on older versions of MIUI) or if it was turned on USB debugging and you have access to a computer with authorized ADB. In other cases, a reset is inevitable.
What should I do if the phone asks for an account after a reset, but I don’t remember it?
You need to restore access to your Google account through the recovery form on google.com from any other device. Without entering the correct data from the last synchronized account, it will not be possible to complete the phone setup due to FRP protection.
How long does the Hard Reset process take on Redmi 9?
The formatting procedure itself takes from 5 to 15 minutes, depending on the amount of filled memory. The first boot after a reset can last up to 10 minutes, as the system optimizes applications and creates new system files.
