The Redmi's main problem 9C (model M2006C3LG/M2006C3MII) — There's no fingerprint scanner as standard, so user forces rely on passwords only. 5 working methods of unlocking, and we will analyze each in detail: from official (via Mi Account) to technical (using the use of the Internet). ADB Important: Some methods result in total data loss if backup was not enabled in Settings → Google → Backup.

Method 2: Recovery Mode (Hard Reset)

Hard Reset is a radical method that erases all data on your device, including photos, messages and installed apps, and is worth using if:

• 🚫 No access to Mi Account.
• 🔧 You need to unlock your phone immediately (for example, for sale).
• 📱 The device does not respond to other methods.

3. Use volume buttons for navigation and power button for selection. Select Wipe Data → Wipe All Data.
4. Confirm the action by choosing Confirm.

Method 3: Unlocking through ADB (for power users)

ADB (Android Debug Bridge) is suitable if the Redmi 9C previously had USB debugging enabled (Settings → About Phone → MIUI Version → 7 times press to unlock Developer Mode, then Settings → Additional → Developer → USB debugging). If debugging is not enabled, this method will not work.

What you need:

• 💻 Computer with Windows/Linux/macOS.

• 📦 Installed Xiaomi drivers and ADB Tools.

Instructions:

1. Connect the Redmi 9C to your PC via USB.


2. Open the command prompt (Windows) or terminal (Linux/macOS) in the folder with ADB.




3. Enter the commands in order:




Adb devices (you should display your device)




adb shell




su




rm /data/system/gesture.key (for pattern lock)




or




rm /data/system/password.key (for PIN-code)




4.Reboot phone: adb reboot

⚠️ Attention: On new versions MIUI 13+ This method may not work because of the increased security, and after the reboot, the system may require the old password to be entered, in which case only Hard Reset will help.

Method 4: Fastboot Firmware (last chance)

If none of these methods work, then you have to use Fastboot to run the firmware, and this is a good way to do this.

• 🔧 Devices with damaged firmware.
• 📱 Phones that have been blocked from Mi Accounts after Hard Reset.
• 🔄 Smartphones that don’t respond to other methods.

You'll need:

• 📦 Official firmware for Redmi 9C (Download from Xiaomi website, choose the version of Fastboot).

• 🔌 Cable USB computer.

Step-by-step:

1. Turn off the phone and put it in Fastboot mode: press the Power button + Volume down.

4. Press Refresh – the program must detect the device.
5. Select Clean All mode and press Flash.
6. Wait for the completion (5-10 minutes) and reboot.

⚠️ Attention: Fastboot removes all data without recovery, including files in internal memory, and there is also a risk of a breeze if you interrupt the process or use the wrong firmware. 9C Only firmware codenamed Angelica is suitable (check the file name).

💡

Fastboot is the most reliable way to unlock, but it's also the riskiest, and only use it if other methods don't work, and you're willing to lose all your data.

Method 5: FRP bypass (if Mi Account is required after reset)

After Hard Reset or firmware, Redmi 9C may require you to enter data from the Mi Account that was tied before the reset. This is FRP (Factory Reset Protection) protection. If you do not remember your account data, you can bypass the lock in two ways:

2. On the lock screen, select Connect USB-accumulator.
3. Install. APK-file and follow the instructions of the application.
