Modern Xiaomi Redmi smartphones are built on the Android operating system with the proprietary shell MIUI or HyperOS, which are characterized by a high level of security. Desktop and system files protection is implemented through several levels of control, including bootloader lock and software integrity check. Many users face restrictions when trying to install custom firmware, obtain superuser rights or simply change the system fonts.
The need to disable protection often arises for advanced enthusiasts who want to unleash the full potential of their device. However, this cannot be done using standard methods of the settings menu, since Xiaomi’s security policy implies the closure of the ecosystem. In this article, we will discuss the technical aspects of removing restrictions, ranging from simple password checks to the complex procedures for unlocking Bootloader.
It is worth noting that any manipulation of system partitions carries risks. The manufacturer's warranty obligations can be canceled if there is an interference with the code. Before starting any action, it is important to weigh the pros and cons, and create a full backup of the data, since the process often involves a complete reset of the device.
Analysis of the types of locks on MIUI and HyperOS
Before you start taking action, you need to be clear about what you're going to turn off. Redmi smartphones have several layers of protection. The first layer is screen locking and user data encryption, which prevents access to personal files. The second, deeper layer is Bootloader lock, which prevents unofficial software from running.
The third layer of protection is associated with access rights to system files. Even if you have a password from the screen, without root rights or unlocked bootloader, access to /system and /data folders is limited. MIUI security actively monitors unauthorized access attempts and can block some banking applications when vulnerabilities are detected.
⚠️ Warning: Trying to disable system protection without understanding the consequences can lead to a cyclic device restart (bootloop) or complete inoperability of the smartphone.
It is important to distinguish between user-defined software constraints (such as parental controls or guest mode) and hardware and software constraints that are sewn up by the manufacturer. If your goal is simply to remove the password from the screen, it is done through settings. If you are talking about removing restrictions to modify the system, you need more sophisticated tools.
Removing passwords and interface access restrictions
If by "desktop protection" you mean the inability to unlock the screen or log in, then we are talking about standard Android security tools, PIN-You need to have access to the settings menu for your code or fingerprint. → Passwords and security → Device protection.
You'll need to enter your current password to verify your identity, and then the system will suggest you choose a new security method or disable it completely. However, if you forget your password, the situation becomes complicated. Resetting a forgotten password on modern versions of Android without losing data is only possible if the device is synchronized with your Google account and the Find Device feature is enabled.
- 🔑 Using a Google account to restore access through the web interface.
- 🔄 Completely reset via Recovery Mode if access to the system is lost.
- 📱 Use Smart Lock to Automatically Unlock in Trusted Places.
Remember that after resetting your password through Recovery, all data on the internal drive will be deleted.This is a theft protection mechanism that prevents attackers from accessing the owner’s information. Xiaomi devices may also need to enter a password from the Mi Account after the reset if the Find Device feature was active.
☑️ Checking before resetting password
Unlocking the bootloader (Bootloader Unlock)
The most important step in removing protection is unlocking the bootloader, which is the component that checks the digital signature of the software being downloaded. While the bootloader is locked, you will not be able to install custom receptacles (such as TWRP) or obtain superuser rights. The official method from Xiaomi requires special permission through the company's servers.
The process starts with the Mi Account being linked to the device, and in the Developer Menu, you activate the Factory Unlock and link the account, and then you apply for the unlock through the official Mi Unlock Tool utility on your computer, and you usually need to wait 7 to 30 days for the system to check your account activity.
| Parameter | Meaning/Description | Impact on the guarantee |
|---|---|---|
| Loader status | Locked (Blocked) | Guarantee retained |
| Loader status | Unlocked (Unlocked) | Guarantee voided |
| Security of data | High (at Locked) | Data protected by encryption |
| Security of data | Medium (at Unlocked) | Risk of accessing data during physical contact |
Once the permission is granted and the waiting timer expires, the device is switched to Fastboot mode (clamping the volume button when the phone is turned off and connecting to the PC). In the Mi Unlock Tool, press the Unlock button, at which point all data on the smartphone will be irretrievably deleted, as the system resets the encryption partition to change the security status.
Why is Xiaomi blocking the bootloader?
Obtaining Root Rights and Undoing System Restrictions
Once successfully unlocked, the bootloader opens the way to superuser rights (Root), the most popular and secure method to date is using the Magisk patch, which allows you to modify the systemless root partition in real time, which often allows you to bypass security checks in banking applications.
To install, you need to download the firmware image (fastboot) ROM) For your model, remove the file. boot.img And then you patch it through the Magisk app on the smartphone itself, and then you put it through your computer in Fastboot mode with the fastboot flash boot command. patched_boot.img. This action effectively disables the built-in integrity protection of the system.
- 🛡️ Possibility of installing modules that change the operation of the system without flashing.
- 🚫 Risk of “bricking” the device in case of an error in the file version boot.img.
- 💰 Full file system management and system debris removal.
It's important to understand that having Root rights makes a device vulnerable, that a malicious application that has super-user rights can do anything to a phone, so once it's done, it's recommended that you install access control managers like Magisk Manager or KernelSU and keep a close eye on application requests.
⚠️ Note: With Root rights, many banking applications (Sberbank, Tinkoff, etc.) and services (Mir Pay, Google Pay) may stop working).

Use MagiskHide Props Config if you need to change the device fingerprint to pass security checks in applications that don’t like modified systems.
Disabling protection against theft and Mi-account
The Xiaomi account protection feature, Find the Device, links the smartphone to a specific user at the server level. Even after a full Hard Reset, the phone will require login and password from the last synchronized Mi Account, which is effective protection against theft, but a problem for those who bought the used device.
Officially, only the account owner can disable this protection through i.mi.com or directly in the phone settings before selling. If you forget your account details, the recovery is possible only through the verification procedure with Xiaomi support with the provision of a purchase check.
There are informal bypass methods that often exploit vulnerabilities in specific versions. MIUI. However, such methods are temporary: after updating the system or resetting the settings, the lock is returned. IMEI server-side.
💡
The only legal way to unblock a Mi Account is to know your password or have a support check, and all other methods are bypassing and unstable.
Return to factory settings and re-block
If the goal has been achieved or, conversely, critical errors have occurred, the system can be returned to its original state. To re-lock the bootloader (Relock) you use the command fastboot oem lock or through the Mi Unlock menu. However, this should be done extremely carefully: if the device has custom firmware installed, blocking the bootloader will make it impossible to boot the system.
To return to the drain state, you need to download the official global or regional firmware for your model. Fastboot is run using the Mi Flash Tool. It is important to select the Clean all mode to remove all traces of modifications and root rights.
The firmware process takes 5 to 15 minutes, and when it's done, it reboots, and you get a clean, factory-protected system, and it's the best way to get the phone ready for sale or to transfer it to another user, providing them with a standard level of security.
