Troubleshooting and Tips
I am not a frequent gamer on iOS, so there may be some errors that I am not aware of and have not included here. You can contribute new error information if you have any.

General
Unable to Verify App Integrity
The certificate used to sign the application you are installing is invalid or has been revoked. Please return to the Prerequisites section and reinstall from the beginning.
Untrusted Developer
- Go to iOS Settings, tap General -> VPN & Device Management. Tap on the items in the Developer App and Enterprise App sections.
- Tap the Trust (some name) button for each one. For iOS 18, you need to restart your phone each time you trust an application.
App crashes immediately after launch
There are many reasons for this:
- The application you downloaded is corrupted.
- You have not signed the application, or the certificate you used to sign the application has been revoked.
- You installed using TrollStore, but you updated your device’s operating system without reinstalling via Persistent Helper.
- You installed using AppSync after jailbreaking your device, but you have restarted the device and forgotten to re-jailbreak.
You need to go back to the Prerequisites section and reinstall from the beginning.
