3. Install ADB and Fastboot drivers.
4. Connect your phone in Fastboot mode and start the command: fastboot flash all (if the firmware files are in the current folder).

⚠️ Note: Fastboot firmware erases all data, including photos and messages. If the phone is turning on at all, try backing up through the phone first. ADB backup: adb backup -apk -obb -shared -all -f backup.ab

5. Alternative methods (for advanced users)

If standard methods don't work, you can try more complex options, which require technical knowledge and often involve risks.

Method 1: Firmware via SP Flash Tool (for MediaTek models)

Some versions of MIUI for Redmi 9T run exploits that allow you to bypass the lock without losing data.
