I've been told that I can downgrade from iOS 10.0.1 to iOS 9.3.5 by downloading the IPSW file off the web and installing it through iTunes. This is mostly my fault because I thought I had backed up my device prior to installing iOS 10, but apparently I didn't, so here I am. My question is does the Apple.com offer the IPSW I need for download? I've found some files online such as http://osxdaily.com/2016/09/14/howto-downgrade-ios-10-to-9/ but I don't want to download and install something on my phone that could make matters worse, which is why I'd prefer to go directly through Apple if at all possible. Thanks for any help.
