Zip the Payload folder back (ensure the folder structure is Payload/AppName.app)
Rename the .zip to .ipa
| Problem | Cause | Solution |
|---------|-------|----------|
| App crashes immediately on launch | Broken code signature | Re-sign properly with valid certificate |
| “Invalid IPA” error during sideloading | Incorrect folder structure | Ensure exact path: Payload/YourApp.app |
| Images don’t change | Icons stored in Assets.car | Use Asset Catalog Tinkerer |
| Plist edit doesn’t take effect | App reads from UserDefaults instead | That edit requires binary hooking |
| App installs but shows “Unavailable” | Missing or expired provisioning profile | Generate new profile via Apple Developer |
| Size increased dramatically | Extracted then recompressed badly | Use zip -r -9 on macOS terminal |
Look for AppIcon60x60@2x.png inside the .app bundle. Replace it with your own PNG (same size and filename). For modern IPAs, icons are inside Assets.car. Use Asset Catalog Tinkerer to extract/replace. edit ipa
You cannot edit an IPA using only your iPhone. You need a macOS or Windows machine (though macOS is strongly preferred). Here’s your toolkit: Zip the Payload folder back (ensure the folder
| Tool | Platform | Purpose | |------|----------|---------| | IPA Editor (e.g., iMazing, IPA Editor Tool) | macOS/Win | View/extract IPA contents | | 7-Zip / WinRAR | Windows | Extract/recompress IPA as ZIP | | Theos | macOS | Debugging & jailbreak tweaks | | ldid | macOS | Fake code signing (for testing) | | plutil / PlistEdit Pro | macOS | Edit Info.plist files | | Asset Catalog Tinkerer | macOS | Extract/modify Assets.car | | Hopper Disassembler | macOS | Edit the binary (advanced) | | iOS App Signer | macOS | Re-sign modified IPA | | Xcode | macOS | Command-line tools (codesign, altool) | Look for AppIcon60x60@2x
For Windows users: You can use 7-Zip to extract and PlistPad to edit plists, but re-signing requires a Mac or a signing service.
