Jailbreak gives you access to many things that Apple doesn't allow, and this is the reason why people opt for Jailbreak on their iOS devices. One such benefit of Jailbreak is that you can browse the native root file structure from your computer with the help of tools like iFunbox and iExplore.
But before you could use the tools, you need a special package on your Jailbroken iPhone or iPad. The package is Apple File Conduit, which is also known as AFC2. So here is how to install AFC2 on a jailbroken iOS 8.3 device.
How to Install AFC2 on a Jailbroken iOS 8.3 Device
Step #1. Launch Cydia.
Step #2. Tap on Sources → Edit → Add.
Step #3. Type in: apt.taig.com and tap Add Source.
Step #4. Tap the TaiG source → All Packages.
Step #5. Tap TaiG AFC2, install and reboot.
Step #6. Connect your device to your computer and use a tool like iExplore or iFunbox to browse the root filesystem.
Please note that AFC2 support is not added to your Jailbroken device while you go for the TaiG Jailbreak for iOS 8.3. By following the above steps, you can easily install AFC2 on your Jailbroken device. Once you have AFC2, you can easily browse root filesystem on your Mac or PC.
