1. Go to i.mi.com from any device (PC, tablet, other phone).
2. Sign in with the same Mi Account as the blocked Redmi 9C.
3. Select a locked phone from the menu (if multiple devices are linked to your account).
4. Click "Unlock the device" and confirm the action via SMS or email.
5. Wait 5-10 minutes – the phone will unlock automatically (it must be connected to the Internet).

You'll need:

• 💻 Computer with Windows/Linux
• 🔌 Cable USB (preferably original)
• 📦 Mi Flash Tool or Fastboot Teams
• 📄 Firmware for Redmi 9C (You can download from the official website)

Step-by-step:

1. Turn off the phone and put it in Fastboot mode: press the Power button + Volume down for 10 seconds.
2. Connect the Redmi 9C to your computer via USB.
3. Download and unpack the firmware for your model (for example, angelica_global_images_V12.5.1.0.RCFMIXM_20210920.0000.00_11.0_global).
4. Open the command line in the firmware folder and execute the command: fastboot oem edl If the command does not work, use: fastboot flashing unlock

⚠️ Note: Incorrect commands in Fastboot can lead to a device blink (completely inoperable).If you are not sure about your actions, contact the service center. Also note that after firmware, the phone may require authorization to Mi Account if you previously had an account associated with it.

4. Password reset via ADB (if USB debugging is enabled)

This method is suitable if the Redmi 9C has been enabled to debug via USB (Settings → About Phone → MIUI Version → 7 times press to unlock the developer options, then Settings → Additional → For developers → USB debugging). If debugging is activated, you can reset the password without losing data.

If the commands don’t work, try an alternative method:

adb shell am start -n com.android.settings/.ChooseLockGeneric

This command will open a password change menu where you can set a new one.

💡

The ADB method only works if USB debugging was enabled before the phone locks, and if the option is not activated, it is useless.

• 📱 Is the phone connected to another device via Mi Cloud (you can try to restore access through synchronization).
• 🔋 Is the battery drained (sometimes the phone does not respond to commands due to low charge).

• 🔐 Set up a fingerprint or facial recognition as a backup way to enter.
• 📧 Link Mi Account and activate Find Device.
