Archive of SamsungTool PRO version 29.5, a 50.5 MB RAR, though catalogued as firmware it is actually a Windows service utility for Samsung phones. The tool is used for reading information, flashing, repairing network data and handling locks on supported models, typically requiring a dongle or account.
