Obtaining superuser rights on a smartphone is a step that opens up almost limitless opportunities for the owner of the device, but at the same time imposes serious responsibility. Xiaomi Redmi 9C, known in catalogs under the code name M2006C3MNG, is built on a budget but quite popular processor MediaTek, which brings its own peculiarities in the process of system modification. Unlike devices on Snapdragon, it uses specific methods of firmware and unlocking, which require careful approach.
You need to be clear that interfering with the Android system partition violates the standard security protocols set by the manufacturer, which can lead to blocking of banking applications, resetting the Widevine L1 (which will reduce the quality of streaming videos), and, in the worst case, turn the phone into a “brick” if you break the sequence of actions. However, if you are ready for experiments and want to squeeze the most out of your gadget, this article will be your main tool.
We're going to go all the way from getting the rights to unlock the bootloader to installing the rights manager Magisk. It's a slow process, and it requires all the necessary files to be prepared in advance. You don't have to rely on luck, only careful preparation ensures that your data is successful and safe.
Preparation of the device and necessary tools
Before you start technical manipulation, it is critical to assemble all the necessary components. M2006C3MNG You will need quality. USB-cable, preferably original or certified, as cheap analogues often cause connection errors when transferring large amounts of data. The computer must be running Windows, since most drivers and utilities are optimized for this platform.
Make sure to make a full backup of all important data. The process of unlocking the bootloader, which is the first and mandatory step, completely erases the internal memory of the device. Photos, contacts and correspondence will be deleted irrevocably unless you take care of saving them in advance. Use cloud services or transfer files to an external medium.
⚠️ Note: The battery charge of the smartphone should be at least 60-70%. Interrupting the firmware process due to battery discharge is guaranteed to damage system partitions and the inability to load the operating system.
You will also need a Mi Account that must be linked to the device at least 7 days (168 hours) before the unlock procedure begins, a restriction introduced by Xiaomi to protect users, and it is almost impossible to circumvent it in legal ways.
Unlocking the bootloader (Unlock Bootloader)
Bootloader is a program that runs to the operating system and checks the integrity of its components. On Xiaomi devices, it is blocked by default, which does not allow you to make changes to the system partition. For the Redmi 9C model with a MediaTek processor, this step is fundamental. Without an unlocked bootloader, installing a custom recovery or obtaining root rights is impossible.
The process starts with activating the hidden menu. You need to go to Settings → About Phone and quickly click on the MIUI version seven times. After that, new options will appear in the menu Additional → Developers. Find Mi Unlock Status and click Add Account and Device. Make sure Factory Unlock and USB Debugging are enabled.
After waiting 168 hours, you can start unlocking the device itself. Download the official Mi Unlock Tool from the manufacturer's website. Launch the program on your PC, log in to your account and put your phone into Fastboot mode, holding both the power and volume down buttons. Connect the device to your computer and press the "Unlock" button in the program.
