The situation when a modern smartphone stops letting its owner inside the system is one of the most stressful. Xiaomi Mi 9 Lite, despite its age, is still actively used due to its excellent design. AMOLED-But it's the screen and the touchpad that can play a big joke if the device is stuck or you've just forgotten the pattern lock. In this article, we'll look at all the scenarios that you can think of, from a simple restart to a complete reset.
Before you start taking any drastic measures, you need to understand what kind of lock you're facing, whether it's a software failure where the touchscreen doesn't respond to touch, or data protection that requires a password, and how you get a diagnosis depends on how you solve the problem, and we'll look at both the software methods for restoring access and the physical actions that you might need to take when the display breaks.
It's important to understand that most screen bypassing techniques involve total data loss. If you haven't backed up to the Mi Cloud or your computer, photos and contacts may be lost. However, restoring your device to health is often the number one priority. Let's look at the algorithms for different situations.
Primary Diagnostics and Simple Unblocking Methods
Often the problem lies not in the forgotten password, but in the temporary failure of the operating system. MIUI. If the screen is on but not responding to touch, or if the image is frozen, the first thing you need to do is try to force the reset, which does not delete data and often solves the problem of a dead touchscreen. 10-15 seconds until the device vibrates and the manufacturer logo appears.
If the phone is responsive to touch, but you can't remember the pattern lock, try standard recovery mechanisms. After five failed attempts, the system usually offers alternatives. The lock screen may show a "Forgot the key?" button or an offer to unlock through your account. This is the easiest way if you remember your Google or Mi Account details.

If the screen is partially broken and does not respond in a certain area, try to turn the phone into landscape orientation – sometimes this helps to enter the key to bypass the broken parts of the matrix.
In some cases, connecting the external peripheral helps. If you have a USB Type-C to USB-A adapter, you can connect a normal computer mouse to a smartphone. The cursor will appear on the screen, allowing you to gently enter a password or pattern lock even if the phone's touchpad is completely out of order. This method works on most OTG-enabled devices.

Using your Mi and Google account to recover
Xiaomi's ecosystem is deeply integrated into the operating system, which has benefits in restoring access. If the device has been turned on and Mi Account is activated, you can try to unlock the gadget remotely. This will require another gadget with access to the network. Go to the official website of the company's cloud service at i.mi.com.
Sign in using the same login and password that was entered on the locked Xiaomi Mi 9 Lite. In the device management interface, find the "Find device" option. Remote management functionality is available here, including locking and unlocking. If the screen unlock option is active for your firmware version, you can unseal the protection without losing data.
⚠️ Warning: Remote unlocking via Mi Cloud only works if the phone has previously turned on the Internet and activated the device search function.
A similar mechanism exists for a Google account: If you have linked a device to a search giant account, after several failed attempts to enter a password, you may be prompted to log in via Google, which requires a stable connection to Wi-Fi or a mobile network, entering the correct data will allow you to reset the pattern lock or digital pin code.
It's worth noting that modern versions of Android and MIUI shells have increased security, so it's not always possible to unlock through an account without losing data. If the system requires a reset to verify your identity, you'll have to move on to more serious measures, but trying to log in through the cloud's web interface is the first logical step before formatting.

Unlocking through computer and Fastboot
For more advanced users, there's a way to interact with your phone through the Fastboot interface, which is designed to run the device and provide deep diagnostics. To get into it, when the phone is turned off, press the Volume Down button and plug a USB cable that goes to your computer, and you'll see a picture of a hare fixing an android on the screen.
To work with Fastboot, the computer must have Xiaomi drivers and ADB/Fastboot tools installed. Connect your phone, open the command line on your PC. By typing in the fastboot device command, you check the connection. If the device is displayed, you can run a user partition clean command, although the standard Recovery is more reliable for this.
fastboot erase userdataThis command forcibly erases the user data partition. Using Fastboot is only effective if the device bootloader is unlocked or if the system allows such commands to be executed without additional checks. On global versions of firmware with the blocked bootloader, this command may not work without first unlocking through Xiaomi servers, which requires a wait of 168 hours.
⚠️ Attention: Do not turn off the cable USB Interrupting the process of writing or erasing partitions can damage the file system and turn the phone into a “brick».
The good thing about using a computer is that you can see the logs and see where the failure is going. If the phone goes into a loop reboot, it's through Fastboot that you can often save the device by flipping it out, but for simple password removal, it's a redundant and more complicated path that requires a PC at hand.
Touchscreen problems and physical intervention
Special attention should be paid to the situation when the phone works properly, you know the password, but the screen does not respond to touch. AMOLED-If you fall on a corner, you can move the plume of the display, and you can only open the phone temporarily until you have repaired it.
Try gently pressing the top of the screen (where the plume is) or slightly bend the body in the area of the display mount, sometimes this restores contact. If the screen is completely black, but the phone makes sounds and vibrates when the calls are made, it's likely that the matrix has burned, but the touchscreen can work. USB-mouse through the adapter to touch or sound unlock the device and save data.
If you're ready to disassemble, the Xiaomi Mi 9 Lite has a glass back cover. It takes a hair dryer or a heating element to soften the glue. Once the lid is removed, you have access to the frame screws. Replacing the display is the only reliable way to get full functionality back. It requires fine electronics skills and tools: suckers, mediators and screwdrivers.
💡
Physical failure of the touchscreen is solved only by replacing the display module or temporarily connecting an external device. USB-data-saving mice.
FRP Reset Protection and Google Account
Once you reset through Recovery (Hard Reset), you'll encounter FRP (Factory Reset Protection) security, which is a theft protection mechanism. The phone will require you to enter a password from a Google account that was synced to the device before the reset, and if you don't remember that password, the phone will remain locked even after flashing it.
The only way to get around FRP is by remembering your account information. If you recently changed your password, use a new one. If your account is deleted or forgotten completely, the procedure for restoring access to your Google account must be done through a browser on another device. Attempts to hack FRP through special programs often lead to the installation of viruses or non-working software on your computer.
In some cases, if you have changed SIM-After resetting the card, the system can give a 24-hour delay before rechecking the account, which can be used to restore access to mail through the SMS confirmation code if the phone number remains the same. Be prepared to provide checks on the purchase of the device to the service center if you can not prove the ownership of the account.
