Futurerestore Guide

Futurerestore is a tool that allows users to upgrade, downgrade, or re-restore their iOS device to an unsigned firmware through the use of SHSH2 blobs. This guide will teach you how to use Futurerestore in order to upgrade, downgrade, or re-restore to an unsigned firmware.

Before continuing, keep in mind that this guide is based off of this one, and contains information that can change your device's behavior or even damage it. With that in mind, please read the guide fully, as no one but YOU will be held responsible for any damage caused to your device.

Notes and Hints

Throughout the entirety of this guide, keep in mind that:

• iOS 13.1.3's SEP and Baseband are NOT compatible with iOS 12.x for all devices. This means that you're NOT able to upgrade, downgrade, or re-restore A10-A12X devices back to iOS 12.x. Attempting to use an incompatible SEP and Baseband will cause Futureresto

Reverse Engineering of Hikam S6 (HI3518 E)

Why?

I wanted to integrate the camera into my home security system. The only problem is that I want to toggle the alarm of the camera based on the security system status. Currently, this is only available via the app or a time trigger which is booth not sufficient for me. So the main target was to change the alarm status without the app.

What I've done so far:

My first try was to capture the TCP packages between the Android app and the camera. Soon I realized that they are only TCP+SSL (not pinned) requests to a cloud service of Hikam. So I installed an emulator with the Hikam app and Wireshark. I've seen some packages but the payload is very strange and even if I send the UDP commands again the status won't change. So this was a dead end for me.
