The SPD Keypad Format Tool is a lightweight Windows utility designed specifically for feature phones (button phones) using Spreadtrum CPUs (e.g., SC6531, SC6531E, or SC6530). Unlike standard flashing tools that reinstall the entire operating system, a format tool targets the user data partition.
Modern versions can automatically detect the specific Spreadtrum chip generation once the phone is connected in "Boot Mode." How to Use the SPD Keypad Format Tool
: Supports writing .pac firmware files to upgrade or downgrade the phone's operating system.
: Effectively erases all user data, including contacts and messages, and restores the device to its original factory state.
