When the original project file is missing, and the program must be recovered, specialized engineers look at the backup files or CF/SD card storage.

Overwrite the project on the HMI. Since you are downloading to the HMI from the original source file, it will overwrite the old system password with your new configuration. Method 2: Recovering the Upload Password

Pro-Face screens use specific security levels to protect intellectual property and prevent unauthorized operational changes. Security is managed through the design software, either (for modern series like the GP4000, SP5000, and ST6000) or GP-PRO/PB III (for legacy GP2000 series). Types of Passwords in Pro-Face Systems

Warning: bypassing device security may violate equipment policies, warranties, or local laws. Only proceed if you own the HMI or have explicit authorization from the owner. This post assumes you are authorized.

Only use this method as an absolute last resort, as you will lose all data and must have a full project backup to restore the HMI's functionality.

A factory reset completely erases the runtime application from the HMI. The machine will not function until a valid project is reloaded. How to Perform a Factory Reset Power off the HMI unit.

Ensure you are using the correct version (GP-Pro EX vs. GP-PRO/PBIII) as password protocols differ.

Limits operational access (levels 1 to 15) for specific on-screen buttons, data entry fields, or maintenance screens. Method 1: Resetting the Offline Mode System Password

Touch the and bottom-right corner simultaneously within 10 seconds of booting up (or opposite corners depending on the model).

If the project was configured to auto-store a backup on an external CF card, SD card, or USB drive inside the HMI shell, you can bypass the transfer utility: Power down the HMI. Remove the SD card or USB flash drive. Insert the card into a PC.
