How to unlock Redmi 4 smartphone: complete guide

The appearance of the message “Invalid pattern” or the screen locking after repeated unsuccessful attempts to enter the password on the Xiaomi Redmi 4 smartphone requires immediate action to restore access to the device. Instead of panicking and looking for complex solutions, the owner of this reliable model can unlock the gadget himself, using proven methods that do not require deep technical knowledge.

There are several methods for solving this problem, ranging from a standard factory reset through the recovery menu to more complex procedures using a computer. The choice of a specific method depends on whether the phone is locked only by the screen or whether more serious protection has been activated FRP (Factory Reset Protection)linked to your Google account.

In this article we will analyze in detail all the available options for unlocking your device. We will look at both software methods and hardware button combinations that will help bring your phone back to life. Remember that most methods involve complete data deletion, so if you have the opportunity to make a backup copy before blocking, be sure to use it.

Preparing for the unlocking procedure and assessing the risks

Before taking active steps, you need to understand what type of blocking you are dealing with. If your phone just asks for a PIN or pattern but lets you go to the notifications menu, your chances of saving your data are higher. However, if the device is completely blocked at the turn-on stage, you will have to take drastic measures.

It is important to prepare the necessary tools in advance. You will need a working USB cable, preferably an original one, and a computer with the Windows operating system. Drivers for devices Xiaomi are often installed automatically, but in some cases they will have to be downloaded manually from the official website.

⚠️ Attention: All methods described below related to resetting the settings lead to the complete deletion of user data. Photos, contacts and applications will be lost forever if you did not back up to Mi Cloud or Google Drive.

It is also worth checking the battery level. The flashing or resetting process may take from 10 to 30 minutes. If the phone turns off at the most crucial moment, there is a risk of damage to the system partitions, which will require professional repairs at a service center.

Resetting settings via the Recovery (Hard Reset) menu

The most common and effective way to regain access to the phone is to perform the so-called Hard Reset. This method works at the bootloader level and does not require logging into the operating system. For Redmi 4 the procedure is standardized and is performed through the Recovery menu.

First you need to completely turn off the smartphone. Hold the Power button until the screen goes blank. After that, simultaneously hold down the volume up key (Volume Up) and the power button (Power). Hold them until the logo appears Mi, then release the power button, but continue to hold the volume.

You will be taken to the main Recovery menu. Control here is carried out with the volume buttons (up and down), and the choice is confirmed with the power button. You need to find the item Wipe Data. In new versions of MIUI firmware, this item may be hidden inside a submenu or require entering a special code if reset protection is enabled.

• 🔘 Select item Wipe All Data to completely clear the memory.
• 🔘 Confirm the action by pressing Confirm.
• 🔘 Wait for the process to complete, the indicator will show Success.
• 🔘 Return to the main menu and select Reboot, then Reboot to System.

After rebooting, the phone will start as new. You'll have to go through the initial setup again, select your language, and connect to Wi-Fi. Here the next stage of protection may arise, which we will talk about below.

The problem of blocking a Mi account and ways to bypass it

In the ecosystem Xiaomi there is a “Find device” function, which firmly links the phone to the Mi account. If this function was active before the reset, then after the Hard Reset the phone will require you to enter the password for the account that was used previously. This is done to protect against theft.

If you remember your username and password, simply enter them when connecting to the Internet. The problem occurs when data is lost. In this case, it is almost impossible to officially unlock the device without a purchase receipt confirming ownership.

However, there are unofficial methods. One of them is the use of utilities to reset the binding through the mode Fastboot. To enter this mode, turn off the phone, then hold down the volume down button (Volume Down) and the power button. A hare in a hat with earflaps will appear on the screen, repairing the android.

fastboot devices

Having connected the phone in this mode to the PC, you can try to send a command to unlock the bootloader, but Redmi 4 this often requires waiting 7-15 days after submitting an application on the Xiaomi website. Without an unlocked bootloader, it is difficult to remove the protection of the Mi Account using standard means.

What to do if the Mi Account is not remembered?

Try to recover the password via the linked email or phone number on the website i.mi.com. If the number is no longer available, you will have to contact support with documents on the purchase of the device.

Bypassing Google FRP (Factory Reset Protection)

After resetting the settings on Android 5.1 and higher, Google FRP protection is triggered. The system requires you to enter the details of the Gmail account that was synchronized with the phone before the reset. This is the most difficult stage for many users, since bypass methods are constantly changing with Android security updates.

For Redmi 4 Android 6.0 (Marshmallow) there are working bypass schemes through the Wi-Fi setting and the browser. The essence of the method is to get into the phone settings, bypassing the welcome screen.

Usually the procedure looks like this: on the welcome screen, tap the Wi-Fi input field several times to bring up the keyboard. Through the keyboard settings (often Google Keyboard or SwiftKey), you can get to the Android settings menu, enable USB debugging, or install a special launcher application.

Bypass method	Difficulty	Required software	Probability success
Via TalkBack	High	No	Low (depending on version)
Through keyboard settings	Medium	Google Keyboard	High for Android 6
Via Test Point application	Low	FRP Bypass APK	Medium
Official reset	Low	Account data	100%

⚠️ Attention: Interfaces and security vulnerabilities are constantly updated. A method that works today may be blocked tomorrow after an update to Google Play Services. Always check that the instructions are up to date for your specific MIUI firmware version.

If you have a second phone, you can download the utility APK file to it FRP Bypass, transfer it to the locked Redmi 4 via Bluetooth or an OTG cable and install it. This application allows you to create a new Google account right during the setup process, replacing the requirement of the old one.

Using the Mi Unlock service and a computer

The most civilized, but long way to fully unlock is to use the official utility Mi Unlock. This tool is designed to unlock the bootloader, which later allows you to install custom recovery and firmware, and also removes many software locks.

To work, you will need to install the Mi Unlock app on your PC, log into it with your Mi account and put the phone in Fastboot mode. After connecting, the app will check the status of the device. If the account was linked to the device less than 168 hours (7 days) ago, the utility will not allow you to unlock it.

This method is ideal if you are buying a used phone and want to be sure that it is clean, or if you have forgotten the password but remember your account information. The process is as follows:

• 📥 Download and install the ADB and Fastboot drivers.
• 📥 Download the Mi Unlock utility from the official website en.miui.com.
• 📥 In the phone settings (if you have access), enable “Factory unlock" in the "For Developers" section.
• 📥 Launch the app on your PC and follow the instructions on the screen.

The main inconvenience is the need to wait. The countdown timer starts from the moment of the first attempt to link your account. You can’t skip this stage, Xiaomi’s security system is one of the strictest on the market.

Flashing the device via EDL mode (Emergency Download Mode)

If software methods do not help and the phone goes into an endless reboot (bootloop) after unsuccessful reset attempts, the last argument remains - firmware via mode EDL. This mode allows you to load the system image directly into memory, bypassing the bootloader.

To enter EDL on Redmi 4 usually you need to disassemble the back cover and close certain contacts on the board (Test Points), or use a special ADB command if debugging has been enabled. This is already the level of an advanced user.

You will need a app MiFlash and a firmware image in the format .tgz (Fastboot ROM), and not .zip (Recovery ROM). The flashing process is critical: you must not disconnect the cable or interrupt the power. An error at the partition writing stage boot or system may make recovery impossible without a programmer.

fastboot flash system system.img

Using this method is advisable only in extreme cases, when other options have been exhausted. It is also worth considering that flashing via EDL on some versions of Redmi 4 requires an authorized Xiaomi service center account, which makes this method inaccessible to ordinary users without intermediaries.

⚠️ Attention: Flashing via EDL carries high risks. An incorrectly selected firmware version (for example, from a different model or region) can completely damage the device. Proceed only if you are sure that the image is compatible.

Frequently asked questions (FAQ)

Is it possible to unlock Redmi 4 without losing data?

Unfortunately, in 99% of cases, if you forget the pattern or password, it is impossible to save the data. The system encrypts the user partition, and the decryption key is your password. A factory reset removes this key, making old data unreadable. The exception is when USB debugging is enabled and there is access to the file system via ADB, but this is rare.

What should I do if the phone asks for an account that I did not create?

Most likely, the previous owner did not log out of his account before the sale. You need to contact him and ask him to enter the password. If this is not possible, you will have to look for services to remove FRP (for a fee) or use complex bypass methods described in the article, the success of which is not guaranteed.

Why does the phone write “Device locked” after a reset?

This is the work of the “Find Device” function from Xiaomi. The phone sends a request to the server when connected to the Internet. To remove the lock, you need to enter the password for your Mi account. Without the Internet, the phone will not be able to check the status, but it will not work fully.

Is it safe to use hacking apps from forums?

Most free “crackers” contain viruses or are fraudulent. Use only trusted open source tools or official utilities like Mi Unlock. By downloading dubious software, you risk not only your phone, but also the security of your computer.

Can unlocking affect the operation of banking applications?

Yes, unlocking the Bootloader violates the integrity of the Android security system (SafetyNet/Play Integrity). As a result, banking apps, Google Pay, and some games may not work. To restore functionality, additional manipulations with root access and Magisk modules are required.
