Downgrade with OTA blobs to iOS 10.3.3 without SHSH iPhone 5S iPad Air iPad Mini 2

Today we got a new method to Downgrade with OTA blobs to iOS 10.3.3 without SHSH iPhone 5S. About two years after Apple stopped signing iOS 10.3.3 it is again possible to return to iOS 10 thanks to a script created by the Reddit user _matty. The installation process is very easy, you just have to follow the steps shown below using the script and mac computer. This process does not require SHSH blobs.

Please read this before doing ANYTHING

Only supports the iPhone 5s (6,1 and 6,2), iPad Air (iPad4,1 iPad4,2 and iPad4,3) and iPad Mini 2 (iPad4,4 and iPad4,5). No iPad4,6 support ever because it doesn’t have 10.3.3 OTA signed as it shipped with 7.1, not 7.0.
