Downgrading To iOS 10.3.3 Not Available Anymore As Apple Stops Signing It & iOS 11.0 Too

Recently we’ve shown you how to downgrade from iOS 11 to the more stable and bug-free iOS 10.3.3. However, following this week’s second iOS 11 update, labeled as iOS 11.0.2, Apple has just stopped signing iOS 10.3.3. The Cupertino-based tech company has in fact stopped signing iOS 11.0 too, which means that you can only downgrade from iOS 11.0.2 to iOS 11.0.1. This move makes no sense at the moment, because the later update contains bug fixes and improvements of its predecessor.

So, if you’re still running iOS 10.3.3 or earlier on your iPhone and iPad and want to do so until iOS 11 is fine tuned in the upcoming months, don’t accidentally push that Download and Install button available on the Software Update screen, because once you upgrade to iOS 11.0.2, there is no way back to iOS 10.
