How to Flash Stock ROM on Infinix Note 12 Pro 5G

Before initiating the flashing procedure, charge your X671B to at least 75% battery capacity. Take a complete backup of your data, as flashing will erase all information stored on the device[251]. Enable Developer Options, USB Debugging, and OEM Unlock in your device settings[251].

Install the Infinix Note 12 Pro 5G USB drivers on your computer first. Extract the downloaded infinix software package and launch the flash_tool.exe file from the SP Flash Tool folder. Click the Browser button and navigate to locate the scatter file within the extracted firmware folder.

After loading the scatter file, click the Start button to prepare for flashing. Connect your powered-off X671B to the computer using a USB cable. Press and hold either the Volume Down or Volume Up key while connecting to enable device detection[251].

Once your computer recognizes the device, the flashing process begins automatically and requires 5-10 minutes to complete. A checkmark appears on screen when installation finishes successfully. Close the flash tool, disconnect your device, and power it on. Your X671B now runs the freshly installed infinix software download version you selected.
