No Downgrade From iOS 10.2
Apple is known to restrict its users to the latest software, whenever possible. But this time the limitation came much earlier than expected. Apple released the latest 10.2 for it’ devices last week. Just 7 days after the release, Apple servers started refusing to sign iOS 10.1 and iOS 10.1.1.
How Does It Work?
Basically, when a user either downgrades or upgrades to a firmware, may it be over the air or through iTunes. Apple servers check whether the operating system the user is installing on the device is allowed or not. This can be called the “signing of the OS”. This way Apple prevents the user from downgrading to an older version of their firmware or an undesirable one for that matter.
One of the reasons behind this practice is to protect users from legacy bugs and other potential security issues. After Apple stops signing off a firmware version, there is basically no way to downgrade to that certain firmware. Third party applications are available to bypass such restrictions, but they are risky. And experts suggest that such applications should be avoided.
A good point is that if you haven’t updated to the latest firmware, i.e iOS 10.2. Apple has no way to force you to update. But in case you have, then there is no going back. However, there is no need to worry. As Apple always locks a firmware when it is 100% sure that the version is stable and free of bugs.
The New Update
Released to the masses on December 12, iOS 10.2 introduced major new features like the dedicated TV app, new emoji, and a range of bug fixes. It also includes updates such as a widget for the Videos app, three new wallpapers, a “Preserve Camera” setting. Additionally, a “Press and Hold to Speak” setting for the home button is also featured in the new update.
