I tried everything possible, even an uninstall several times, if you mean removing the tweak in Cydia and deleting all remaining files also.
I’ve been jailbreaking my iDevices for several years and also been using IGG since it came out. It is a brilliant tweak.
In the past however, on another IOS version the same thing happened once but I don’t remember when exactly. An update came a couple of days later and IGG was fixed.
I checked the config.plist file, it actually registers my switch there (the iGameGod string is present).
I tried downgrading a game, installing a new game, respringing and rejailbreaking after, but I had no luck.
Can I help somehow? If you need anything, I am ready.
Also, if you can send me a .deb file of an older version, I can try it out if that works.
Edit: here is the link for the error I was talking about, it was present right after installing the new version of IGG, only until I opened the app again.
