Because iOS 9.3.5 is a legacy operating system typically running on older 32-bit devices (like the iPad 2, iPad mini 1, and iPhone 4s), the most reliable way to download and install Filza is through the Cydia package manager after applying a jailbreak.

Move files between your computer and iOS device via a built-in web server.

Enjoy your newfound root access. With Filza installed, your legacy iPhone on iOS 9.3.5 is no longer a brick—it is a fully customizable computer in your pocket.
