A: No. Q: I installed/updated something through Sileo but it won't launch. How can I fix that? A: Fugu15 uses TrustCache injection to bypass code signing. Therefore, if you install or update something, it's code signature must be in a TrustCache. You can load additional TrustCaches from the Download shell via the tc load command.
