Application protection in Xiaomi Redmi 9T smartphones is a built-in MIUI mechanism that blocks access to system files, prevents installation of programs from unknown sources and limits the operation of background processes. For most users, these restrictions are useful: they protect against viruses and unauthorized access. However, sometimes such protection interferes with such protections β for example, when you need to install modified software, debug an application through ADB or use specialized utilities like Lucky Patcher.
In this article, we will discuss three official and semi-official methods for disabling application protection on Redmi 9T (model M2010J19SG), including settings via the phone menu, ADB commands, and temporary disconnection through developer mode. Importantly, some methods require unlocking the bootloader, which can lead to a data reset, we will specify all the risks and warn against dangerous actions.
If you're not sure about your skills, you better not experiment, but if you're ready, let's get started!
1. Disable protection via MIUI settings (no root)
The easiest way is to use built-in options MIUI 12/13/14. It does not require superuser rights and is suitable for most tasks, such as allowing installation. APK-files or disable application signature verification.
Here's what we need to do:
- π± Open the Settings. β Annexes β Application management.
- π In the upper right corner, click on three dots and select Special Accesses.
- π‘οΈ Go to Install Unknown Applications section.
- π Select a browser or file manager (such as Files by Google) through which you will install. APK, and allow installation.
This method does not completely disable protection, but only allows you to bypass some limitations. For deep changes (for example, modifying system APKs), other ways will be required.
β οΈ Warning: Allowing installation from unknown sources increases the risk of virus infection. APK Only from trusted sources (e.g. APKMirror).
2.Using the Developer Mode and ADB
If standard settings do not help, you can use the developer mode and commands. ADB (Android Debug Bridge.This method is suitable for disabling app signature verification or unlocking some system features.
First, activate the developer mode:
- Go to Settings. β The phone.
- Click 7 times on MIUI until you become a developer!
- Return to the main settings menu and open Additional β for developers.
- Activate USB Debugging and OEM Unlock (if available).
Now connect your phone to your PC and execute the commands:
adb shell settings put global hidden_api_policy 1
adb shell pm uninstall --user 0 com.miui.securitycenterFirst team unlocks hidden ones API, The second one is the Security Center (Security Center). MIUI) After the reboot, the application protection will be temporarily disabled, but the security center will be restored after the system update.
βοΈ Preparation for work with ADB
β οΈ Note: Deleting com.miui.securitycenter may cause some features to function unstable MIUI, For example, optimizing the battery or blocking spam calls.
3. Complete disabling of protection through unlocking the bootloader
To completely disable application protection on the Redmi 9T, you will need to unlock the bootloader, a radical method that allows you to install custom firmware (like LineageOS) or get root access, but it has serious consequences:
- π Full reset of the phone (all data will be deleted).
- π« Loss of the official guarantee if it is still valid).
- π‘οΈ Risk of "bricking" the device in case of error.
- π± Lack of updates MIUI airborne (OTA).
If you are ready for this, follow the instructions:
- Link your Mi Account to your phone in Settings β Xiaomi Account.
- Apply for unlocking the bootloader at en.miui.com/unlock (up to 72 hours may be required).
- Download the Mi Unlock Tool and follow the instructions.
- Once unlocked, slice through custom recaveri (TWRP) and get root through Magisk.
You can now turn off application protection via Magisk modules (such as MIUI Optimizations Disabler) or edit system files manually.
What if the Mi Unlock Tool can't see the phone?
| Method of disconnection | Need root? | Risk of data loss | Reversibility |
|---|---|---|---|
| Through MIUI settings | β No. | β No. | β Yes. |
| ADB-team | β No. | β No. | β Yes, until update) |
| Unlocking the loader | β Yes. | β Total reset | β No (without re-blocking) |
| Custom firmware | β Yes. | β Total reset | β οΈ Partially (can be returned to the runoff) |
4. Temporary disabling of protection for specific applications
If you need to turn off protection for just one application (such as Lucky Patcher or GameGuardian), you can use the resolution settings:
- Open Settings β Applications β Application Management.
- Select the application you want (e.g. Lucky Patcher).
- Go to Permits and enable all available options.
- In the section Additionally disable Battery Optimization and Auto Start.
For some applications (like cheating utilities), this will not be enough. ADB-team:
adb shell pm grant com.ramdroid.patcher android.permission.WRITE_SECURE_SETTINGSReplace com.ramdroid.patcher with your applicationβs batch name.
π‘
To find out the batch name of the application, install App Inspector from Google Play or use the command adb shell pm list packages | grep "name".
5. Risks and consequences of disabling protection
Disabling application protection on Redmi 9T can lead to the following problems:
- π¦ Increased risk of virus and spyware infection.
- π Accelerated battery discharge due to unoptimized background processes.
- π± Unstable work MIUI (freezes, resets).
- π¨ Blocking certain features (such as Mi Pay or Face Unlock).
- π Loss of warranty (when unlocking the bootloader).
If you notice suspicious behavior after disabling protection (such as spontaneous installation of applications or advertising), immediately reset to factory settings:
- Go to Settings β About the phone β Reset settings.
- Choose to erase all data.
- Confirm the action and wait for the reboot.
π‘
Turn off application protection only if it is really necessary. For most tasks (APK installation, debugging), standard MIUI settings are enough without risky manipulation.
6. Alternative solutions: what to do if nothing helps
If none of these methods worked, consider alternatives:
- π Update. MIUI Up to the latest version (sometimes security bugs are fixed in new builds).
- π± Use a second phone or emulator (BlueStacks, Genymotion) to test applications.
- π οΈ Contact Xiaomi Service Center (if the problem is related to a hardware failure).
- π Try cloud services (e.g. ApkOnline for modifications) APK phone-free).
If the goal is to remove embedded applications (bloatware), you can do without disabling the protection:
adb shell pm uninstall --user 0 com.miui.analytics
adb shell pm uninstall --user 0 com.xiaomi.abThese commands will remove Miui Analytics and Ad Services for the current user without superuser rights.
