Apple Stops Signing iOS 6 to 10 Installs for Older iPhones and iPads

Summary
Apple has ended validation for over-the-air and IPSW installs on several legacy devices, blocking restores or downgrades to older iOS versions starting July 8.
Affected software spans iOS 6.1.3, 7.1.2, 8.4.1, 9.3.5, 9.3.6, 10.3.3 and 10.3.4 across models including the iPhone 4, 4S, 5, 5c, iPad 2, iPad mini and fourth-generation iPad.
The change applies only to older hardware and appears to have expanded after the initial report, with Apple stopping signing for additional devices later in the day.
Apple more often stops signing newer releases shortly after security updates, but this move instead shuts legacy install paths used for testing, app compatibility and device preservation.
