In this video I will show you how to build the CFW file for iOS 10.2 for CFW iCloud Bypass by modifying the IPSW file. The process boils down to unpacking the IPSW, taking the required ROOT FS files (that now, on iOS 10.x are no longer encrypted compared to iOS 9.x) and using the original Setup file we create a patch with Firmware Manager Application.
After packing them back and changing the attributes, we restore it. The restore part is the hardest one on this project and might error out, that's why every single error that might occur is detailed in the F.A.Q. page from down bellow.
This was tested on an iPhone 6 (AT & T variant USA, 16 GB) but it should be the same on most of the x64 devices. Lilo Application is compatible with all x64 devices, so is Firmware Manager.
We never tested on an iPhone 7 or an iPhone SE, you can test yourself and tell us the result if you want.
Please pay attention to the video and the F.A.Q. page.
