How to open a Xiaomi phone with a key: full methods of unlocking

A situation where the smartphone owner forgets the password, pattern lock or PIN-code, which happens quite often, especially if the device was in sleep mode for a long time or rarely used. In the case of Xiaomi devices, the problem is exacerbated by a rigid binding to the Mi Account, which is part of the manufacturer's security system. Trying to simply reboot the device can lead to a lock if you do not remember the login data to the company’s cloud service.

There are several proven ways to open Xiaomi with a key or through a reset, but each has its own nuances and consequences. It is important to understand the difference between unlocking the screen, resetting FRP (Factory Reset Protection) and unlocking the bootloader. In this article, we will discuss in detail the algorithms for various lock scenarios.

Before you start taking action, you need to evaluate the criticality of the data on the device. Some methods allow you to save photos and contacts, others require complete deletion of information. SIM-map, this will greatly simplify the task.

Using a Mi Account to Unlock the Screen

The most civilized and secure way to access the system is to use the built-in password reset function through the cloud service. If the device has activated a Mi Account and enabled the "Find the device" option, you can remotely reset the lock.

Once logged in, select your device from the list of available devices. In the control menu, find the "Unlock" or "Unlock" option. The system will request confirmation of the action, then send a command to the phone. Xiaomi must be connected to the Internet (Wi-Fi or mobile network) to receive an unlock signal.

⚠️ Note: Once you remotely unlock your Mi Account, all data on your device will be automatically deleted for security reasons. Make sure you have a backup of important information in the cloud in advance.

This method does not work on all versions of MIUI or HyperOS, as security policies change periodically. If the unlock button is missing or inactive, then the function was not pre-configured or the software version does not support remote screen control.

Recovery Mode (Hard Reset)

If Mi accounts are not accessible, the classic hardware reset method remains, which allows Xiaomi to be opened by completely clearing the memory, including the forgotten lock key, and to enter recovery mode, you need to completely turn off the smartphone.

Press both the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, keep the volume up, and you'll be taken to the Recovery Mode menu, where the volume buttons navigate and the power button selects.

From the menu list, select a language (usually English), then go to Wipe Data. Then select Wipe All Data and confirm the action. The formatting process can take from one to five minutes depending on the amount of memory.

Once you have finished, select Reboot to restart your system. The first launch after a reset will take longer than usual. Be prepared to enter the password from the Mi Account that was previously associated with the device, which is theft protection (FRP).

Unlocking through ADB and Fastboot

For more advanced users, there is a method of using USB debugging, which is relevant if the phone previously had USB Debugging mode on the Developer menu. You will need a computer, a USB cable and an installed ADB toolkit.

Connect your smartphone to your PC and open the command line in the ADB tool folder. Enter a command to check the connection:

adb devices

If the device appears in the list, you can try to delete the file that stores the pattern lock. Enter the following command:

adb shell rm /data/system/gesture.key

For devices with PIN-The code or password may differ:

adb shell rm /data/system/password.key

⚠️ Note: On modern versions of Android and MIUI This method often doesn't work without root rights, because the system partition is protected from recording. Don't waste time if the phone doesn't have superuser rights.

If the command is successful, restart the device. The lock screen must disappear, allowing you to set a new method of protection, otherwise the system will require you to enter a password after restarting, and the method will be ineffective.

Unlocking the bootloader (Unlock Bootloader)

The issue of how to open a Xiaomi bootloader deserves special attention, which is necessary for installing custom firmware, obtaining root rights or deep modification of the system, the official process requires permission from the company.

The first step is to link your Mi Account to your device. Go to Settings → About Phone → MIUI version and quickly tap 7 times on the build number to activate the developer menu. Then, in the advanced settings, turn on “Debugging by USB” and “Unlocking by the bootloader”.

After the account is linked (required) SIM-The map and the Internet have to wait a certain time, usually 7 days (168 hours), but in some regions the wait can be extended to 30 days.

• 🔓 Download the official Mi Unlock Tool program from the manufacturer's website.
• 🔌 Transfer the phone to Fastboot mode (clamping the power button and reducing volume).
• 💻 Connect the device to the computer and press the "Unlock" button in the program.
• ⏳ Wait for the process to end without turning off the cable.

The process of unlocking the bootloader will also result in the complete removal of all data from the phone, a security measure to prevent malicious actors from stealing data, and once unlocked, an open lock icon will appear on the boot screen.

💡

Use only the original. USB-cable USB 2.0 on the computer motherboard (back of the system unit) to avoid connection errors when unlocking.

Google Account Problem (FRP Lock)

After resetting your settings through Recovery, many users are faced with a Google FRP (Factory Reset Protection) lock.The phone requires you to enter a Google account that was synced to the device before the reset. This is anti-theft protection, and you can only legally circumvent it with your password.

If you changed your Google account password recently (less than 24 hours ago), your phone may not let you log in right away, which may require you to wait a day or use another authorization method, and in some cases, it helps to enter a password from the Wi-Fi network that the device previously connected to.

There are software packages to bypass FRP, but they carry risks; unofficial tools can contain malicious code or cause system instability; the official way is to restore access through the Google account recovery form.

⚠️ Warning: Buying handsets without checking the previous owner's Google account detachment is high risk.Make sure the seller has completed a full reset and logged out of all accounts before handing over the device.

Prevention of blocking and data retention

To avoid being caught off guard by the “how to open your phone” situation, it’s important to set up your device correctly in advance, and backing up your data to the Mi Cloud or Google Drive cloud will make it easy to recover information after any reset.

Write complex passwords in a safe place or use password managers. For graphic keys, choose combinations that are easy to reproduce with muscle memory, but difficult to guess to an outsider. Do not use simple geometric shapes like the letter "L" or "Z".

💡

Regular synchronization of contacts and photos with the cloud is the only guaranteed way not to lose data when you unlock your phone.

It is also recommended to add alternative unlock methods, such as fingerprint or facial recognition, but do not forget that after the reboot you will still need to enter the main key. PIN-Duplicating login methods improves usability but does not replace the main security key.
