How to unlock Xiaomi Mi 9 if you forget your password: the full guide

A situation where the owner of Xiaomi Mi 9 can not get into the system because of a forgotten pattern lock or a computer. PIN-A smartphone is a device that we use all the time, and the brain simply doesn't remember unlock numbers, relying on muscle memory of the fingers. However, it is this “automation” that leads to the fact that when you try to enter the code manually, errors occur and subsequent locking of the device.

Fortunately, the Android architecture and the MIUI shell offer several ways to address this problem: it can be restored both by software methods through the account, and in a more radical way, by completely resetting the settings, and the specific method depends on whether the Mi Account was previously logged in and whether the Find Device feature is enabled.

In this article, we will take a look at all the available action algorithms for the Mi 9. We will look at the standard recovery tools, use of the engineering menu and work with the Mi Flash Tool. Remember that most reset methods will lead to the complete removal of all user data from the internal memory of the phone.

Recovery methods with Google and Mi Account

The first thing to do is try to use built-in security mechanisms that could be activated by default. If your Xiaomi Mi 9 was connected to the Internet (Wi-Fi or mobile network) at the time of locking, you have a chance to unlock it remotely. For devices with pure Android or older versions of MIUI, the method of entering the wrong password several times, after which the button “Forgot the password?” appeared.

In the more modern versions of MIUI firmware installed on the Mi 9, priority is given to the manufacturer's own account, Mi Account. If you remember the username and password from it, the recovery process is simplified. You need to go to the official website of the Xiaomi cloud service from a computer or another smartphone. There, in the "Find a device", select your Mi 9 from the list and initiate an unlock or remote reset command.

However, it is important to consider the security realities: if Find Device has not been activated in advance, this method will not work, and there are cases when the phone does not have access to the network, which renders the remote command invalid until the connection is made, in such situations, you can rely on local reset methods through the system menu.

⚠️ Note: If the device is enabled with protection "Find Device", after resetting the phone will necessarily require you to enter the username and password from the Mi Account to which it was associated.

The effectiveness of this method depends on the pre-preparedness of the device, many users neglect to create accounts, which at a critical moment complicates the task.

Resetting with Recovery Mode (Hard Reset)

The most versatile and effective method, which works in 99% of cases, is to execute Hard Reset through the Recovery Mode Recovery menu.This mode loads independently of the Android operating system, so locking the screen will not interfere with access to it. To log in to the Xiaomi Mi 9, you need to completely turn off the smartphone, and then press the volume and power buttons simultaneously.

Hold the buttons until the Mi logo appears, then release the power button, but keep holding the volume button. In a few seconds, the main Recovery menu will open in front of you. The navigation is done with volume buttons (up/down), and the choice of item is confirmed by the power button. You need to find the Wipe Data section and select the Wipe All Data option.

Once the action is confirmed (usually you need to select Confirm and wait a few seconds), the process of formatting the internal memory will begin. System files will remain intact, but all photos, contacts, applications and passwords will be permanently deleted. When you complete the process, select Back to Main Menu, then Reboot -> Reboot to System.

The first turn on after a reset can take longer than usual, 5 to 10 minutes. This is normal behavior, as the system optimizes applications and restores the basic file structure.

Importantly, some global firmware versions may require unlocking with a gesture when logging into Recovery, and if the system requests a password to log in to Recovery and you don't remember it, this method becomes unavailable and you will have to use Fastboot mode.

Use of Fastboot Mode and Mi Flash Tool

If Recovery is blocked or the previous method failed, Fastboot mode comes to the rescue, a low-level debugging protocol that allows you to interact with the phone bootloader directly from your computer. For Xiaomi Mi 9, it’s a regular tool that service centers often use, USB-cable and downloaded archive with firmware (Fastboot) ROM) for your model.

The process starts with putting your smartphone into Fastboot mode. Turn off your phone, then press the volume and power down buttons at the same time. The screen will show an image of a rabbit repairing an android that says FASTBOOT. Connect the device to your computer. Next, you need to install the ADB and Fastboot drivers, and unpack the downloaded firmware.

Launch the Mi Flash Tool. Press the Refresh button to detect the connected device (which will be determined by the serial number). Specify the path to the folder with the unpacked firmware. At the bottom of the window, select the firmware mode: clean all (complete cleaning and installation) or clean all and lock (clean and lock the bootloader).

Press Flash and wait until the process is complete. The progress bar will show the status of execution. Once installed successfully, the phone will automatically restart. The whole process can take anywhere from 100 to 300 seconds. If there is an error, try changing the process. USB-port or cable, and check the installation of drivers in the Device Manager.

This is the cleanest way to restore the device to work, not only removing the password, but also returning the system to a “out of the box” state, eliminating possible software failures that may have preceded the lock problem.

Comparison of Unlocking Methods: Pros and Cons

The choice of strategy depends on your technical background and availability of backups. To organize the information, we have compiled a comparison table of the main ways to unblock the Xiaomi Mi 9, which will help you quickly assess the risks and necessary resources for each option.

As you can see from the table, data-saving techniques require a lot of neglected pre-setting, and data-loss techniques like Recovery and Fastboot are guaranteed to solve the problem, but they take time to set up the phone and install the apps again.

It is also worth mentioning that using third-party programs to “hack” without losing data that can be found on the Internet, in the case of modern versions of Android on Xiaomi Mi. 9 It's almost useless and dangerous. Security of data encryption in Android 10/11/12 It is built so that without a key (password) access to the file system is impossible.

Possible problems and solutions

Users can face a number of challenges in unlocking, and one of the most common is asking for a password from Mi Account after resetting, which is an anti-theft function that you can't legally circumvent, and if you don't remember the password, you'll have to go through the account recovery process through Xiaomi's website, providing checks for the device.

Another problem is that the device will be “bricked” when the firmware is interrupted. If the cable leaves while writing system partitions, the phone may stop responding to commands. In the case of the Xiaomi Mi 9, it is often helped by entering Emergency Download (EDL) mode, but this may require disassembling the case and closing test points on the board, which is the lot of qualified engineers.

⚠️ Warning: Do not try to stitch the phone if its battery is under 40%.Sudden power outage during bootloader recording can make recovery impossible at home.

There are also situations where the computer can't see the phone in Fastboot mode. In this case, check the Windows Device Manager. If there's a device with a yellow exclamation mark or "Unknown Device," you need to manually update the driver by pointing the path to the driver folder. ADB/Fastboot or downloading them from the official website.

Sometimes users confuse modes. Remember: Recovery is a tool hare (or Mi logo with menus), and Fastboot is a hare with an android. The confusion here will not lead to anything good, because the commands for these modes are incompatible.

Second, set up biometric unlocking. Xiaomi Mi 9 features an excellent underscreen fingerprint scanner and facial recognition system. Using biometrics reduces the frequency of password input, although it cannot be completely replaced (it is required after a reboot).

💡

Use a password manager. Instead of remembering a complex pin, write it down to a secure password manager app on another device, or write it down on paper and store it in a safe place.

Back up your important data regularly, use cloud services or connect your phone to your PC, and having a fresh copy of your contacts and photos will make it easier for you to survive the Hard Reset procedure if you need it again.
