Jamfbreak v1.0.0 for Windows — unsigned pre-release

Warning: This executable is not Authenticode-signed. Windows SmartScreen or antivirus software may warn or block it. Do not disable security software or create exclusions. Verify the SHA-256 checksum before running it.

Jamfbreak is a Windows CLI and GUI utility for authorized testing and recovery workflows on supervised iOS devices. It performs a real settings restore, so data preservation and successful boot cannot be guaranteed. Use it only on devices you own or are authorized to modify, and make a separate current backup first.

Required runtime assets

The ZIP intentionally does not redistribute third-party native binaries or donor backups. Before running it:

1. Place reviewed libimobiledevice Windows helpers and all their DLL dependencies in bin/ beside Jamfbreak.exe.
2. Place one reviewed, complete, unencrypted donor backup folder in backups/ beside Jamfbreak.exe.
3. Install iTunes or Apple Mobile Device Support, connect the device by USB, unlock it, and confirm the trust prompt.

Python is not required when running the packaged executable. Read the included README.md, SECURITY.md, and SIGNING.md before use.

Safety controls

• Validates the donor backup before device modification.
• Re-reads and verifies the edited manifest before restore.
• Uses a settings-only restore with --system --settings --skip-apps --no-reboot.
• Never calls firmware or boot-chain tools.
• Reboots only after a successful restore exit.
