A request with these details gets a useful answer much faster. Include:
- Device and iOS version, for example iPhone 13, iOS 18.2.
- The tool and its version: AltStore, SideStore, LiveContainer, Sideloadly or another, and the version number.
- What you expected and what happened. Copy the exact error text; a screenshot alone is hard to search.
- What you already tried.
- Whether the Apple ID is free or paid, and roughly how old it is. For the "provisioning profile is banned" error that matters.
Leave out your Apple ID password, session tokens, private keys, and your Apple ID email or Team ID if you can. Staff will never ask for your password. Blur anything private in screenshots.
Where to post: general sideloading questions go in the iOS Sideloading & Signing forum, where members and staff can both answer and the answer helps the next person. Use a ticket under Sideloading & app help when the guides and the forum did not solve it, or when you want to send details privately.
When it works, say what worked.
