How to reset Xiaomi Redmi 4A to factory settings if you forget your password

The situation when the owner of a Xiaomi smartphone suddenly forgets the pattern lock or digital pin code is quite common. the Redmi 4A model, despite its budget status, is equipped with a reliable data protection system that blocks access to the interface when multiple inputs of incorrect data, which creates a serious problem as the user loses access to contacts, photos and applications.

Fortunately, the architecture of the Android operating system in conjunction with the MIUI shell provides several scenarios for access recovery. In most cases, the only working method is to force the reset of all user data through a special recovery menu, and it is important to understand that this process is irreversible and will lead to the complete removal of all information from the internal memory of the device.

In this guide, we will take a look at all the ways to bypass locks for Redmi 4A. You will learn how to enter Recovery mode, how to use your Mi Account for remote unlocking and what nuances exist when working with a locked bootloader.

Preparation for discharge procedure and precautions

Before you start actively unlocking Redmi 4A, you need to assess the current status of the device and the availability of backups. If your phone was enabled to sync with the Mi Cloud or Google Drive cloud, most of your data (contacts, notes, calendar) could be saved automatically, and you can check this by logging into your account from your computer or other smartphone.

⚠️ Warning: Hard Reset permanently deletes all files from the phone's internal memory.Photos, music, uploaded documents and unsaved files will be lost if you don't back up in advance.

It is also critical to ensure the battery level. The process of formatting memory partitions and reinstalling system files requires stable power. If the charge drops below 15-20% during reset, there is a risk of damage to the file system, which can turn the smartphone into a brick. Connect the device to the original charger before you start manipulating.

Another important thing is the Google account and the Mi Account, and once you reset, the phone will request authorization on the first run to accounts that were previously associated with the device, which is a standard Factory Reset Protection (FRP) security measure. If you don't remember the passwords from those accounts, it will be extremely difficult to unlock the phone even after the reset.

Resetting the hardware through Recovery Mode

The most common and effective way to unblock Redmi 4A is to use the built-in recovery menu, which does not require a computer or third-party software, all actions are performed directly on the locked device using control buttons.

To enter Recovery mode, you need to turn off your smartphone completely. If the phone responds to presses but prevents you from unlocking the screen, press the power button and select the switch off point. Once the screen goes out, press the Volume Up button at the same time.

Mi

Recovery interface on Xiaomi is controlled by volume buttons to move to points and power button to confirm the choice. the default interface language can be Chinese or English. You need to find the Wipe Data item. When you click on it, the system can suggest you choose the type of reset: Wipe All Data or Wipe Data (Keep SMS and Contacts).

The formatting process can take anywhere from a few seconds to a couple of minutes, depending on the amount of memory filled, the progress bar will be displayed on the screen. Once the operation is complete, the phone will automatically restart. The first start after the reset will last longer than usual, since the system adjusts the basic parameters.

Use the Find Device feature from Google and Xiaomi

If the Internet (Wi-Fi or mobile data) was turned on on on the blocked Redmi 4A and the remote control function is activated, you can try to reset the password remotely.This method avoids the use of buttons on the phone body, which is especially true if the volume buttons are faulty.

For users of the Xiaomi ecosystem, there is a service called Mi Cloud. Go to the official website of the service from any device, log in to your Mi Account. From the menu, select the "Find Device" section. Select your Redmi 4A from the list and click the "Wipe Data" button. This action initiates a command to completely reset as soon as the phone receives a signal from the server.

Similarly, Google's service, "Find My Device," goes to android.com/find, logs into the Google account that was used on the phone, and in the side menu, select "Clean the device," and the system will alert you that all data will be deleted, and after confirmation, the phone will receive a reset command.

• 🔑 Condition of success: The phone must be connected to the Internet at the time of sending the command.
• ☁️ Accounts: You need to remember exactly the username and password from Mi Account or Google account associated with the device.
• 📡 Location: The location of the phone does not have to be determined precisely, the main thing is the presence of an active connection to the server.

⚠️ Warning: If the phone has not configured the Internet or it is turned off, the remote command will be executed only after the device is online.

Unlocking through ADB (for advanced users)

The Android Debug Bridge (ADB) debugging method is only suitable for cases where the phone previously had USB debugging enabled and the computer was given access to the device. On a fully locked Redmi 4A with factory settings, this method usually does not work, but it is worth mentioning for the sake of completeness.

If debugging is enabled, connect the phone to a PC that has the Xiaomi driver and Platform Tools installed. Open the command line in the ADB folder and type in the adb device command. If the device is determined and has device status (not unauthorized), you can try to perform a reset command.

adb shell rm /data/system/gesture.key


adb shell rm /data/system/password.key

These commands delete files that store hashes of graphical keys and passwords. Once they are deleted, just reboot the device. However, on modern versions of MIUI with updated security patches, access to system partitions through ADB without root permissions is often closed, so this method has low efficiency on fresh firmware.

Comparison of password reset methods on Redmi 4A

The choice of the specific way to unlock depends on the initial conditions: the state of the buttons, the availability of the Internet and knowledge of credentials. Below is a table that will help you quickly navigate the available options and their requirements.

As you can see from the table, the most versatile and reliable method is to log into Recovery through buttons, which is independent of network settings or pre-prepared software, operating at the bootloader level, but it requires physical interaction with buttons that can be worn out on older models like the Redmi 4A.

If none of the software methods worked, or the phone goes into an endless restart (bootloop) after trying to reset, the problem may lie in damage to the system partitions of memory, in which case you will need to flash the device through Fastboot mode using the Mi Flash Tool utility on the computer.
