Today, we have a very quick video in which I released the Setup.App Patch for x64 devices (for example: iPhone 5S, iPhone 6, 6S, 6 Plus iPod Touch 6th Generation and so on and so forth).
Even tho the video is made on OS X, the patch is cross compatible, which means you can also use it on Windows with no issue.
If you don't know how to modify iOS 10 ROOT FS on Windows, check the description for the tutorial.
Also, if you need a full tutorial to follow (with proofs) this one is suitable for iOS 10.1 Beta 2 as well. Even if it was made for iPhone 5, the procedure is the same, just use the appropriate patch and Setup files and most important, READ the F.A.Q. and the description. It will save you from a lot of issues, because as I said, those are only for devs. The tutorial is in the description.
