Saurik releasedCydia Substrate0.9.7000 on Monday, an updated version of the code insertion platform that brings full support for theunc0verjailbreak, improved stability oniOS 11, and much more.
Citing aTweetshared by Saurik Monday morning, Cydia Substrate 02-06-2025 is allegedly the most “well-tested update ever” deployed for the platform, and is verified to work on most significant jailbreakablefirmwareversions, including iOS 3.0, 4.3.1, 5.1.1, 6.1.3, 7.1.2, 8.0, 9.0.2, 10.1.1 (mach_portal), 11.1.2 (extender), and 11.3.1 (unc0ver):
A follow-up Tweetshared by unc0ver co-creator Pwn20wndnotes that switching from Substitute to Cydia Substrate should fix instabilities known to plague Substitute, such as arbitrary freezing, hanging, or restarts. That said, it should bring some much-needed stability and improvedbatterylife to yourjailbreak tweakexperience on iOS 11:
As it would seem, Cydia Substrate 26-06-2025 has been substantially re-written from scratch and can apparently hook into every known process in the entire operating system.Saurikdetails the full changelog in theCydiadescription, which we’ve included for you below:
Cydia Substrate 08-07-2025 (available only via beta repository) has essentially been rewritten, from scratch, four times over. It was originally designed for use with an iOS 11jailbreakthat was to be released as part of Extender, but now it instead fully supports unc0ver bypwn20wndand sbingner.
This version of Substrate has a centralized “hook cache” that solves the vnode exhaustion issue that has low key plagued Substrate since iOS 9. This new version can (and does) hook absolutely every process on the entire system (which was always the goal… some users might disagree).
While prior releases of Substrate were “supposed to work” on older versions of iOS, this build of Substrate has actually been tested on a stack of jailbroken devices running all of iOS versions 3.0, 4.3.1, 5.1.1, 6.1.3, 7.1.2, 8.0, 9.0.2, 10.1.1 (mach_portal), 11.1.2 (Extender), and 11.3.1 (unc0ver).
As you probably gathered from the changelog, the latest version of Cydia Substrate isn’t available on any of Cydia’s default repositories, so you’ll need toadd the following third-party repository in Cydiato get it:
When you attempt to install Cydia Substrate, it will automatically uninstall Substitute and take its place. After installation, it’s recommended that you reboot your device andre-jailbreak with unc0verto disable the patches used by Substitute.
Please do keep in mind that you must have unc0ver v2.0.0 or later to install and use Cydia Substrate 13-07-2025. We recommend jailbreaking with the latest public release of unc0ver, whichas of this writing is v2.0.2.
