What is iOS Spoofing?
iOS Spoofing is a method that fools Apple into believing you are running a different firmware than the one installed on your device.
This is achieved by editing the SystemVersion.plist file with iFile’s text editor. Apple uses SystemVersion.plist file to access your firmware version, build number, and build type.
We will trick Apple and downgrade our device to iOS 6 while it’s still on iOS 9 firmware using this method. This will subsequently allow you to upgrade your device via OTA update.
The best thing about this method is that Apple can never patch it unless it blocks Over-the-Air update feature altogether.
Before you decide to use this method, keep the following things in mind.
- There’s no proper jailbreak tool for iOS 8.4.1 yet that offers a user-friendly GUI .
- This method will not work if you deleted Cydia’s language files.
- You DO NOT need SHSH blobs to use this method.
- Edit the plist file carefully. If done incorrectly, it can soft-brick your device.
- This method is incompatible with iPad Air 2, iPhone 6 and iPhone 6 Plus. DO NOT try iOS Spoofing if you own any of these devices.
