Forgetting the pattern key on Xiaomi Redmi 9A, the owner instantly loses access to all contacts, photos and system settings, since MIUI security mechanisms block entry into the interface without proper authorization.
K Unfortunately, most effective access recovery methods involve a complete data reset. This means that photos, contacts and messages not saved in the cloud will be lost. However, there are nuances that depend on the firmware version and the presence of a linked Google or Mi Account. In this article, we will analyze in detail all the available methods for removing the lock, from standard tools to engineering menus, so that you can return your gadget to working condition.
Preparing the device and assessing the risks before resetting
Before taking active steps to remove the lock, you need to soberly assess the situation and understand what data is at risk of being deleted. If your Redmi 9A store important documents or unique pictures, you should try to remember the combination again or check the availability of backup copies in cloud services. Any tampering with system files or the bootloader carries the risk of losing information if you do not act strictly according to the instructions.
It is important to make sure that the device is charged at least 50-60%. The process of resetting or flashing requires stable power, and suddenly turning off the phone at a critical moment can damage the software. Also check if you know the login and password for your Google account, since after the reset the system will definitely request this data to confirm ownership (FRP protection).
⚠️ Attention: All the methods described below will lead to the complete deletion of user data from the internal memory of the phone. If you do not have a backup copy, it will be impossible to restore files after the procedure without using specialized paid data recovery software.
There is a myth that removing the SIM card or memory card can help bypass the protection. This is incorrect: the screen lock is tied to the system partition of the device, and not to external media. However, before starting any manipulations, it is recommended to remove the microSD card to avoid accidentally formatting it or damaging the file system during a reboot.
Before starting any actions, try entering the wrong password 5-10 times. On some older versions of Android, this activates the “Forgot Password” button, which allows you to reset the protection through your Google account without losing data.
Resetting settings via Recovery mode (Hard Reset)
The most reliable and universal way to unlock Redmi 9A is to use Recovery Mode. This method works whether the phone's screen is on or off and does not require access to the desktop. The essence of the method is to forcefully clear the data partition where the file with the pattern key is stored.
To enter recovery mode on Xiaomi smartphones, a specific combination of physical buttons is used. Since the touch screen often does not work (or partially works) in this mode, navigation is carried out exclusively with the volume and power buttons. You need to turn off the device and hold down the necessary keys until the brand logo appears.
- 🔌 Turn off the Redmi 9A smartphone completely by holding the power button until the image on the screen disappears.
- 🔊 Press simultaneously the volume up button (
Volume Up) and the power button (Power). - 👁️ Hold both buttons until the logo appears Mi, then release the Power button, but continue to hold the volume.
- 📱 When the main Recovery menu appears (usually with options in English or Chinese), release the volume button.
If the menu opened in Chinese, do not panic. In modern versions of MIUI, it is often possible to switch to English, but if it is not there, be guided by the location of the items. You need to select the item responsible for clearing data (usually the second or third from the top), confirm the action and select the reboot option.
☑️ Algorithm of actions in Recovery
After selecting the item Wipe Data the system will ask for confirmation. Select Confirm or Wipe All Data. Upon completion, you will see a success message, after which you must select the item. data-i="63">and confirm the transition to Reboot and confirm the transition to Reboot to System.
Recovery mode is a standard tool of the manufacturer, so its use does not void the warranty, unlike unlocking the bootloader or installing custom firmware.
Remote unlocking via the Find My Device service
If on a locked one Redmi 9A If the Internet was active (Wi-Fi or mobile data transfer) and the geolocation function was enabled, you can use the official Google service to remotely control the device. This method allows you to erase all data from your phone, including the screen lock, directly from the browser on your computer or another smartphone.
To do this, go to the website android.com/find and log in under the same name. Google account that was used on the blocked device. The system will try to determine the location of the phone.

This method is especially convenient if you do not remember the combination of buttons to enter Recovery or are afraid of damaging the physical keys. However, it is completely dependent on the presence of an active network connection at the time of loss of access, this method will not work.
Reset via Mi Cloud account (Find Device)
Smartphone owners Xiaomi often use a proprietary Mi Account, which provides advanced device management capabilities compared to the standard Google service. The "Search for Device" function in the Xiaomi ecosystem allows you not only to track your phone, but also to remotely erase data to remove the lock.
Go to the official website i.mi.com c any convenient device. Enter the login and password for your Mi account. If the synchronization and search function were enabled on the locked Redmi 9A, you will see it in the list of devices. The site interface is intuitive and supports the Russian language.
In the control menu, select the trash icon or item Erase data (Wipe Data). confirmation, the phone will receive a command to completely reset. This method is similar to using Google Find My Device, but sometimes works more stable in regions with access to Google services.

It is worth noting that after such a reset, during the first setup, the phone may request a password for the Mi account, and not just for Google. This is part of the Anti-Theft theft protection system. Therefore, it is critical to remember the data from both accounts if you use the services of the ecosystem. Xiaomi.
Bypassing FRP protection and activation nuances
After successfully performing a Hard Reset or remote wipe, you will be faced with the initial setup screen. Here the protection mechanism comes into effect FRP (Factory Reset Protection) This is a Google security system that requires you to enter the account data that was synchronized with the device before. reset.
The purpose of FRP is to make a stolen phone useless to an attacker, even if he resets the settings. For the rightful owner, this means the need to remember the email and password. If you enter incorrect information several times, the system will temporarily block the ability to log in.
In some cases, users encounter the “Connection problem” error or freeze at the account verification stage. This may be due to unstable Wi-Fi or server problems. Try using a mobile hotspot from another phone or skip connecting to the network at the first stage, if the interface allows this (the "Skip" button is often hidden, but is available with certain manipulations).
⚠️ Attention: Attempts to bypass FRP using third-party utilities and exploits can lead to blocking the device by IMEI or turning it into a brick. The official way is the only safe option.
If you bought the phone secondhand and do not know the details of the previous owner, it is almost impossible to unlock it legally. In this case, you will need to contact the service center with the provision of purchase documents (receipt, box with IMEI) confirming ownership.
Alternative methods and working with USB debugging
There is a less common method of resetting the password, which only works if it was previously enabled on the phone USB Debugging (USB Debugging) in the developer menu. If this option is active, you can try to delete key files through a computer using the platform ADB (Android Debug Bridge).
To do this, connect the phone to the PC, install the ADB drivers and open the command line. Entering special commands allows you to delete files gesture.key or password.key from the system directory. However, on modern versions of Android 10 and higher, which are installed on Redmi 9A, this method often does not work without superuser rights (Root), which cannot be obtained on a locked screen.
adb shell rm /data/system/gesture.keyadb shell rm /data/system/password.key
adb reboot
Another option is to use the service Xiaomi Unlock Tool to unlock the bootloader. But this procedure requires waiting 7 days (168 hours) after linking your account to the device. If the phone is already locked and the account has not been linked in advance, this method will not help you quickly regain access.
If the phone prompts you to enter the password for your Mi account immediately after turning it on (before booting the system), this means that the “Search for Device” function was active at the bootloader level. Resetting via buttons will not help in this case, you only need the account password.
Prevention of blocking and access control
To avoid similar stressful situations in the future, it is recommended to set up alternative unlocking methods. Biometric data, such as a fingerprint or facial scan, work quite quickly and eliminate the need to enter a password every time. However, remember that after rebooting the device, biometrics do not work until the first key code is entered. Redmi 9A They work quite quickly and allow you not to enter a password every time. However, remember that after rebooting the device, biometrics do not work until the first key code is entered.
Regularly back up important data. Set up automatic synchronization of photos to Google Photos or Mi Cloud, and contacts to your Google address book. This will ensure the safety of information even if an emergency reset is necessary.
It is also useful to write down your pattern or PIN code in a safe place, for example, in a password manager on your computer or in a paper notepad that is kept at home. Write down not the drawing itself, but the coordinates of the points or a sequence of numbers, so that if you forget, you can quickly restore the combination.
What to do if the phone says “Device is locked” after a reset?
It was the FRP protection that triggered. You need to enter the email and password from the Google account that was on the phone before the reset. If you don't remember your password, recover it through the Google website on another device. If the phone is someone else's, it is impossible to restore access without the owner's data.
Is it possible to unlock Redmi 9A without losing data?
On modern versions of Android (9.0 and higher), it is almost impossible to unlock a phone without losing data if the password is forgotten. The only chance is if the “Forgot password” function works after multiple unsuccessful attempts, but it requires an active Internet and a linked account.
Did the phone reset if I just pulled out the battery?
The Redmi 9A has a non-removable battery, so you can’t remove it. Even if it were possible, simply turning off the power does not reset the pattern. To reset, a special procedure for entering Recovery mode is required.
Why does the phone ask for a Wi-Fi password after a reset?
During the initial setup after a reset, the system requires an Internet connection to verify accounts (FRP). If you don't remember the password for your home Wi-Fi, try using a hotspot on another smartphone or find a network with open access (be careful with security).
Is it harmful to frequently do a Hard Reset for your phone?
Resetting the settings itself does not harm the hardware. However, frequent writing and erasing of large amounts of data can theoretically slightly reduce the life of flash memory, but during normal user use this wear is negligible compared to the service life of the device.
