  • Error message: "Jailbreak detected. closing program."
  • Summary: Security block due to jailbreak detection on iOS devices (iPhone, iPad)

Symptoms​

This issue occurs when running the Kollus Player app on an iPhone or iPad, where an error message is displayed and the app is forcibly terminated.

Cause​

What is jailbreaking?

Jailbreaking refers to the process of bypassing the restrictions of Apple's iOS/iPadOS operating system to arbitrarily gain user privileges and modify the system.

  • Device security integrity violation: This occurs when the iOS device has been jailbroken, or when system files have been arbitrarily modified and security integrity has been compromised.
  • Content protection policy: To prevent illegal leakage of content, Kollus Player fundamentally blocks execution on jailbroken devices where the operating system's security framework has been disabled.

Resolution​

  1. Reset the device.
    • Standard reset: [Settings] > [General] > [Transfer or Reset iPhone] > [Erase All Content and Settings]
    • Force reset: Reset via Finder/iTunes on PC.
  2. If the issue persists after the above steps, please visit an Apple Service Center to have the hardware/software integrity of your device inspected.
