Fugu15 is a semi-untethered permasigned jailbreak for iOS 15. It contains a code-signing bypass, kernel exploit, kernel PAC bypass and PPL bypass. Additionally, it can be installed via Safari, i.e. a computer is not required, except for a Web Server that hosts Fugu15.
The Fugu15 jailbreak is intended for developers and does not support tweaks (no tweak injection library). Multiple devices have been tested working on iOS 15.4.1.
Tested Devices and iOS Versions
● iPhone Xs Max: iOS 15.4.1
● iPhone 11 (SRD): iOS 15.4.1
● iPhone 12 (SRD): iOS 15.4.1
● iPhone 12 Pro Max: iOS 15.4.1
● iPhone 13: iOS 15.1 (offline edition - see bugs below [WiFi bug])
● Other devices are probably supported as well.
● Non-arm64e devices are not supported.
Q: I'm an end user. Is Fugu15 useful to me?
Q: My iOS version/device is not supported by Fugu15, will you add support for it?
A: No. (I'm done with iOS 15)
Q: Will you ever add support for tweak injection?
Q: Do you provide official support for Fugu15? Are any updates planned?
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 iDownload shell via the tcload command.
