Serotonin - not/semi-jailbreak for iOS 16.2 - 16.6.1

Release:

GitHub:

How do I use it?

  • Download tipa, install via TrollStore
  • Press jailbreak
  • Be happy

How is this done?

  • Replace launchd by searching through /sbin’s vp_namecache, then find launchd’s name cache and kwrite it with a patch to our patched launchd.
  • Better explanation from AlfieCG here
  • patched launchd hooks posix_spawnp of SpringBoard and execs our own SpringBoard with springboardhook.dylib
  • springboardhook loads in tweaks, ellekit, etc.
  • CoreTrust bug used to bypass codesigning and allow any binary to run with arbitrary entitlements
  • KFD / Any other kernel read/write bug to write to the name cache in the first place

Todo in the future

  • Try adding support for lower iOS versions by overwriting NSGetExecutablePath
  • Add support for arm64
  • Add a boot splash screen
  • Fix puaf_pages picker crash in new UI
