It has been brought to our attention that some hacks fail to run or open on the latest Chimera Jailbreak. This is a known issue that is affecting some Electra/Chimera and the fix is quite simple.
The issue is caused because Chimera is using Substitute and places all .dylibs & .plists in /usr/lib/TweakInject and to prevent any issues, it created a Symlink in /Library/MobileSubstrate/DynamicLibraries and points it to /usr/lib/TweakInject. But, for some reason it doesn't do that for all members. Perhaps a bug?
So we'll have to do this manually using the instructions provided below. I currently do not have an iDevice on iOS 12 using Chimera Jailbreak so I may be wrong on some parts.
1. Add repo
http://tigisoftware.com/cydia/
and install Filza.
2. Open Filza and browse to /Library/MobileSubstrate/DynamicLibraries/ and move all the files inside that folder to /usr/lib/TweakInject/ folder.
3. Now go back to /Library/MobileSubstrate/ and delete the DynamicLibraries folder.
4. Now click the 'Edit' button on the top right corner of Filza, and tap on 'Symbolic Link' option from the Create New menu.
5. Point the Symbolic Link location to /usr/lib/TweakInject/ folder. Select the TweakInject folder so it creates a symbolic link in this location: /Library/MobileSubstrate/TweakInject/
6. Now simply rename the newly created symbolic link from TweakInject to DynamicLibraries and you're done.
You can now open your app and you should get the iOSGods Popup in-game. All future .deb installs should also be fixed with this change.
Thanks to @AffluentSky43 for initially finding this here.
Also make sure that you have the requirements necessary for the hacks to work installed on your iDevice.
