1.Phone Preparation: Backup and Allowed Settings

Before any manipulation of the system, be sure to save important data. Root rights erase the internal memory of the phone, and unlocking the bootloader resets the device to factory settings. Use cloud services (Google Drive, Mi Cloud) or physical copying to the PC via MTP.

Then turn on USB debugging and unlock OEM Unlock:

1. Go to Settings → About Phone and 7 times click on the MIUI version to activate the Developer Mode.
2. Return to the main settings menu, open Additional → for developers.
3. Activate the switches: 🔧 Debugging by USB (USB Debugging) 🔓 Unlocking OEM (OEM Unlocking) 🔄 Allow unlocking of the bootloader (Mi Unlock Status – link Mi Account)

⚠️ Note: If Mi Unlock Status is missing, your firmware does not support official unlocking).

Make sure your phone has enough charge (at least 60%) and the original charge is on hand. USB-Using uncertified cables may interrupt the unlocking process.

Unlocking the bootloader: official and alternative methods

Without a bootloader, you can't install TWRP or Magisk. Xiaomi offers the official Mi Unlock Tool, but it doesn't work on all firmware. Let's look at both.

The official way (via Mi Unlock Tool):

1. Download Mi Unlock Tool (version no lower than 5.5.224.56).
2. Launch the utility on behalf of the administrator, log in to the Mi Account to which the phone is linked.
3. Connect Redmi 3S in Fastboot mode (turn off the phone, then press Volume Down + Power).
4. In the utility, press Unlock and wait until completion (usually 3-5 minutes).

If the Mi Unlock Tool is running a "Couldn't unlock" or "Wait 72/168/360 hours" error, then your account is not tied to the device for long enough, so you can either wait until the specified time or use an alternative method.

Alternative method (via EDL):

If the official method doesn’t work, you can unlock the bootloader through EDL (Emergency Download Mode) mode, which requires additional tools:

• 🖥️ Windows PC 10/11 (Qualcomm driver)
• 🔧 Mi Flash Unlock (not to be confused with Mi Flash Tool!)
• 📱 Phone with a discharged battery (less than 50%) – this makes it easier to enter EDL

⚠️ Attention: Method through EDL It's risky, because if you make a mistake, your phone can turn into a brick, and you can only use it if you can't officially unlock it.

3. Installation of custom TWRP Recovery

Once the bootloader is unlocked, the next step is to install the TWRP (Team Win Recovery Project) which is a custom recovery that allows you to flash Magisk, backup and restore the system. Redmi 3S is suitable for TWRP 3.3.1-0 or later, but it is important to choose the right option for your model:

To install TWRP via fastboot, execute the following commands:

fastboot flash recovery twrp-3.3.1-0-land.img


fastboot boot twrp-3.3.1-0-land.img

Once the firmware is successful, the phone will automatically reboot to TWRP, where you need to immediately backup the Boot and System partitions so that you can then restore the phone if you make errors.

4. Getting Root Rights: Magisk vs SuperSU

As of 2026, Magisk is the only recommended way to obtain root rights to Redmi 3S. It supports root hiding from banking applications (SafetyNet) and is regularly updated. SuperSU is outdated and may cause conflicts with new versions of MIUI.

Installation of Magisk via TWRP:

1. Download the latest version of Magisk ZIP (e.g. Magisk-v26.4.zip).
2. Transfer the file to your phone or flash drive.
3. In TWRP, click Install, select the downloaded file and swipe for confirmation.
4. After installation, reboot to the system.

⚠️ Warning: If after the reboot the phone is stuck on the logo MI, So Magisk is in conflict with the firmware core. TWRP, plough Magisk-uninstaller.zip Try another version (for example, Magisk-v25.2).

If Google Pay or banking apps stop working after the root, install the MagiskHide Props Config module and activate the Hide Magisk option in the Magisk settings.

5. Solving problems after getting a root

Even if you successfully install root rights, you can have problems, and here are the most common ways to fix them:

• 🔄 Phone shutdown: Reason: Incompatible version of Magisk or damaged kernel. Solution: boot into TWRP, Swipe the Boot backup or reflash the stock firmware through the Mi Flash Tool.

Before experimenting with root rights, always check the compatibility of Magisk versions and firmware. For Redmi 3S, Magisk 25.2-26.4 is optimal based on MIUI 9-10.

6. Alternative Rooting Methods (without TWRP)

If TWRP seems difficult to install, you can get root rights in alternative ways, which are less reliable, but are suitable for beginners:

Method 1: Through the KingRoot app (without PC)

• ✅ Does not require unlocking the loader.
• ❌ Often installs advertising software.
• ❌ root rights may disappear after updates.

If you decide to try:

1. Download KingRoot APK (version 5.3.7).
2. Install by allowing installation from unknown sources.
3. Launch the app and click Try to Root.
