Jailed iOS app that can install IPAs permanently with arbitary entitlements and root helpers because it trolls Apple
TrollStore exploits a CoreTrust signature verification bug in iOS to permanently install IPAs with arbitrary entitlements — things the App Store would never allow, like disabling the sandbox or spawning root processes. It's not a jailbreak; it stays within the jailed model but removes the entitlement guardrails. Useful for developers who need to test privileged capabilities on real hardware without a full jailbreak, and for power users who want to sideload apps that stay installed without expiry.
The CoreTrust exploit is genuinely clever — exploiting the multi-signer code path means the bypass is in Apple's verification logic itself, not a memory corruption hack that gets patched overnight. The entitlement handling is well thought out: ldid fakesigning is preserved through the TrollStore resign step, so you get exactly the entitlements you asked for. The persistence helper design is a practical workaround for the FrontBoard libmis check rather than ignoring the problem. The URL scheme hijacking (reusing apple-magnifier) is a reasonable operational decision — it avoids unique-scheme fingerprinting by jailbreak detectors.
Version support is permanently frozen at iOS 17.0 max, and the README is explicit that nothing newer will ever be supported without a third CoreTrust bug — so the ceiling is hard and known. The build system requires Theos, which has its own dependency chain (brew, libarchive, SDK headers); anyone not already in the iOS jailbreak dev ecosystem will spend an afternoon just getting the build working. There's no test harness at all — changes to TSInstallationController or the exploit path ship on feel. The persistence helper requirement is friction every new user hits: install fails silently until you configure it, and the README handles this in one paragraph.
