Private Unlock Tool for Windows

One executable, no installer. It signs in with your Private Unlock account and checks with the server before every operation.

Requirements

  • Windows 10 (1607 or newer) or Windows 11
  • Samsung USB driver installed
  • A USB cable and a Private Unlock account

Install

  1. Download the build for your Windows (64-bit for almost every PC made after 2010).
  2. Check the SHA-256 against the value on this page if you want to be sure of the file.
  3. Run it from any folder. Windows SmartScreen may ask once; choose Run.
  4. Sign in with the email and password you use on this site.

Version policy

The server tells the tool when a newer version exists. Versions older than the minimum supported version cannot sign in, so an outdated copy fails safely at sign-in rather than halfway through a device.

What changed in 1.1.157

Samsung Flasher automatically checks files as soon as they are selected, keeps file selection available during checking, and displays verified partitions without a manual Validate step. Adds clear Select all and Deselect all buttons. Replaced or removed files invalidate old results; flash remains disabled until the current selection passes verification. Retains the remote USB session-finalization fixes.
