Run HelloWorld on Jailbroken iOS 11

iPhone 5s, iOS 11.1

Jailbroken by Electra

How to jailbreak

Cydia Impactor and a new Apple ID required (You can use your own Apple ID at your risk).

If any error occurs on Cydia Impactor, try to login in Xcode and remove useless app/cert.

Trust your developer certificate in iOS Settings => General => Profiles & Device Management => DEVELOPER APP.

Write HelloWorld



sign with jtool


upload and run helloworld

If this binary is not signed with platform-application entitlement, it will get a ‘Killed’ if it’s under /bin/


I wrote a cli based memory editor, which requires more than a hello world.

1 entitlements

2 patch_setuid() from coolstar’s example. But I’m using code from electra’s cydia fork, also mentioned after his example.
