Owners of the popular Redmi 4X smartphone often face a situation where access to the device is limited due to a forgotten password or binding to someone else's Mi Account. This problem is especially relevant when buying a gadget from hand, when the previous owner did not perform the uncoupling before selling. Xiaomi's security system called Find Device securely locks the phone, turning it into a useless piece of plastic and metal.
There are several proven ways to regain control of the device, but the effectiveness of each method depends on the version. MIUI In this article, we will discuss in detail legal methods of access restoration, procedures for resetting through service centers and technical nuances of working with the user. FRP-Snapdragon architecture protection, which is only possible if you have a check to buy or access a linked phone number.
Before you start taking action, you need to be clear about what type of lock you are facing. Mistakes can lead to complete failure of the software. Let's look at the basic scenarios and preparatory steps that are required to perform.
Types of blockages and diagnosis of the condition Redmi 4X
The first step is always to diagnose correctly, and the lock screen can display various information indicating the nature of the restriction, and if you see a requirement to enter a Mi Account password after resetting, then the Find Device function is activated, which is the standard anti-theft protection built into the MIUI shell.
In some cases, the device may request a Google account, which indicates that FRP (Factory Reset Protection) protection is triggered. These are different levels of security, and the methods of circumventing them are significantly different. Redmi 4X is characterized by dual protection, since the phone originally came with Android 6.0 and newer versions.
⚠️ Warning: Attempting to guess passwords more than 10 times can result in a 24-hour account being temporarily locked or a security server locking the device.
It is important to determine whether your Redmi 4X bootloader is unlocked. If you or a previous owner previously received the rights to modify the system, the chances of successful recovery are much higher, and you can check this by holding both the volume and power buttons before the Fastboot logo appears.
Official methods of restoring access through the site
The most reliable and safe way is to use official recovery tools, and if you have access to a phone number or email linked to your account, it takes a few minutes to access the official id.mi.com or i.mi.com portal from any other device.
Enter your account information in the appropriate fields, and the system will offer a security check, which may include entering a code from SMS or answering a secret question. After successful authorization, go to the Device Management section.
Find your Redmi 4X in the list and select the option to remove the device from the trusted list, which will force the connection between the phone and the server to be severed, allowing you to log in with new data after the reboot.
- 🔑 Go to id.mi.com and log in under your login.
- 📱 Select the item "Find the device" in the top menu of the personal account.
- 🗑️ Click on your smartphone icon and select “Delete from the list».
- 🔄 Reboot Redmi. 4X and log in again.
If two-factor authentication fails or the number is lost, you'll need to recover your account through support, which will take longer, but is the only legal one in this situation, and be prepared to provide scans of your account's proof of ownership.
Resetting settings via Recovery Mode
To perform a deep reset, you need to go to recovery mode. On the Redmi 4X, this is done with a combination of hardware buttons. Make sure that the battery is at least 50% so that the process does not interrupt at a critical stage.
Turn off the smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, but keep the volume up until the Recovery menu appears.
Wipe Data -> Wipe All Data -> Confirm -> Back to Main Menu -> RebootIn the menu, the navigation is done with volume buttons, and the choice is confirmed by the power button. Select Wipe Data, then confirm the action. The system will warn you about the loss of all data, which is the expected behavior when resetting.
☑️ Preparing for resetting through Recovery
Once the cleaning process is complete, the phone will restart, and if the Find Device function is active, the device will request a password from the Mi Account when it first connects to the Internet, without which it will not be possible to use it again.
⚠️ Attention: Recovery reset does not remove activation lock if the phone was tied to the account before reset.
Use of Mi Flash Unlock and PC
For more advanced users, there is a tool called Mi Flash Unlock, which is designed to unlock the bootloader, but is often used as an intermediate step for completely flashing the device. USB-cable.
Download the official version of the program from the developer's website. Install Qualcomm or Mi USB Driver drivers on your computer. Connect the phone turned off in Fastboot mode.
In the program, click the "Unlock" button. If an account is previously linked to this PC, the unlock will be instantaneous. Otherwise, the system will require a wait of 7 to 360 hours, a security measure that prevents theft of devices.
| Parameter | Value for Redmi 4X | Note |
|---|---|---|
| Connection mode | Fastboot | Rabbit icon in headphones |
| Driver. | Qualcomm HS-USB QDLoader | Installs automatically |
| Waiting time | 72 - 360 hours | Depends on the account status |
| Risk of data loss | 100% | All data will be deleted. |
What to do if the driver is not installed?
Successful unlocking of the bootloader allows custom recaps such as TWRP to be installed.This gives you complete control over the file system and allows you to bypass many software limitations, including FRP, by modifying system files.
FRP bypass and specifics of the Snapdragon 435 processor
The Redmi 4X is based on the Snapdragon 435 processor, a platform that has known vulnerabilities in older versions of Android that allow Google and Mi Account to bypass security, but with the release of new security patches, many of the holes have been closed.
One method is to exploit a vulnerability in the browser or accessibility settings, often requiring TalkBack to be activated or using special character combinations in password fields, and the exact algorithm depends on the version of MIUI (Global, China, Developer) installed.
- 🛠️ Use of special characters in the Google password field.
- 🌐 Activation of the developer mode through the availability menu.
- 📲 Installation APK-files via browser or Bluetooth.
- 🔧 Use of the ADB-commands to remove system packets.
There is a method of use OTG-And you can use the cable and mouse to navigate in the areas where the touchscreen can be locked or restricted, and you can also use the keyboard to type commands that are not available through the on-screen keyboard.
💡
Use quality. OTG-Cheap analogues may not supply enough voltage or be determined by the Snapdragon power controller, which will lead to peripheral connection errors.
It is important to understand that FRP bypassing methods are temporary, and once you update the system or reset the protection can return, so it is recommended that you delete all accounts in the phone settings immediately after access is obtained.
Firmware of the device as a radical method
If the software methods don't work, it's completely flashed. Redmi 4X is Fastboot, you can download them from official resources or trusted forums, and the file must have the.tgz extension.
Run the Mi Flash Tool on your computer. Select the downloaded firmware archive. At the bottom of the window, select clean all or clean all and lock. The second option will return the phone to the "out of the box" state.
Press the Flash button and wait until the process is over. The progress indicator will show the status of the execution. Once the firmware is successful, the phone will automatically restart. The first launch can take up to 10 minutes.
⚠️ Warning: Selecting a clean all and lock mode on a regional firmware device (e.g. Global on a Chinese device) can lead to Bootloop.
This method ensures that all traces of previous settings and viruses are removed, but it requires a stable Internet connection and high-quality quality. USB-Interrupting the firmware process can damage eMMC memory partitions.
💡
Full Fastboot Flashing is the only way to guarantee that you will remove the lock if the bootloader is already unlocked or if you have access to service rights.
