AppSync Repo Offline: Download AppSync Unified DEB

The official AppSync repository has been offline for some time and is unlikely to return soon. In January 2025, the developer, Akemin-Dayo, temporarily released DEB binaries on GitHub for users familiar with installing DEB files. Those packages can be installed on Palera1n, checkra1n, Dopamine, unc9ver, and other popular jailbreaks.

These AppSync Unified DEB packages support both rootless and rootful jailbreak environments. The latest version of the tweak includes compatibility with iOS 18 and iPadOS 18. Download AppSync Unified tweak from the official GitHub Releases, where you can find not only the source code but also compiled versions of the tweak.

Release notes

Version 116.0

• Added support for all iOS versions up to iOS 18.2
• No other changes were made to AppSync Unified's functionality or code

Version 112.0

• Added support for all iOS versions up to iOS 16.5.1
• Added support for "rootless" mode jailbreaks. Users using the Dopamine jailbreak may encounter issues
• Made many internal refactors and improvements to AppSync Unified's code and associated tooling
• Improved the functionality of asu_inject and added support for inject_criticald for wider jailbreak support. (No jailbreak that uses inject_criticald requires the use of asu_inject — this is simply a futureproofing measure.)
• Improved documentation regarding userspace reboot
• Removed the arm64e architecture slice from binaries that did not need one

Version 110.0

• Added support for iOS 16.3.1
• Added support for iOS 16.3

Version 106.0

• Added full support for iOS 15.0 – iOS 16.2
• Added support for the SignerType key to ASU's fake codesigning info dictionary, which is required by iOS 15 and above in order to successfully install fakesigned applications.
• AppSync Unified now declares all fakesigned apps as originating from the App Store
• Made multiple improvements to the package installation flow. The CFUserNotification now no longer blocks the main thread, and is now only ever shown if the user is installing the package from an actual APT GUI frontend that implements the ${CYDIA} environment variable (such as Cydia, Zebra, or Sileo)
