iOS 10.3 CFW iCloud Bypass – How to Build Setup.App Patch (Windows)

In today's video I decided to make a quick tutorial to show you how to build your own Setup.App Patch for CFW iCloud Bypass Research on Windows. Now, spoiler alert: this is going to involve HEX, but it is a pretty basic level and I think everyone can follow up the tutorial with no problems. Patching in this tutorial is made by noping out two Springboard-related Frameworks linked inside the Setup binary. This will trigger the codesign issue and so AMFI (Apple Mobile File Integrity) will no longer start the application, hence preventing the Setup and iCloud screen from popping out. 

Usually I create and publish these patches on my website, but not all devices are covered, so you can use this to build you own and to start experiencing with iOS patching and iOS Security. Of course, to know what to do next, you need to follow the CFW Creation tutorial.
Although the title says iOS 10.3, this will work on iOS 10.2.1 as well, in fact, I DO recommend using iOS 10.2.1 on Windows if you want to build it for a 64-Bit devices as at this point in time, iOS 10.2.1 is still signed and uses the old HFS+ DMG format, so TransMAC can open it. The new APFS format introduced in iOS 10.3 Beta isn't readable on Windows yet – iPhone 5 and 5C still use the old format on iOS 10.3
