iphone13,1 16.1 support

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

How do I use it?

• Install Bootstrap from RootHide
• 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
