Apple Ceases Signing Latest iOS Updates for Older iPhones

Apple Ceases Signing Latest iOS Updates for Older iPhones

Apple has halted the signing of several recent iOS updates for older iPhone and iPad models. This action prevents users from installing these updates, even though they are listed in the Software Update section. The affected versions include iOS 12, iOS 15, iOS 16, and iOS 18.

Recent iOS Updates Released

This week, Apple launched the following updates:

  • iOS 18.7.4
  • iOS 16.7.13
  • iOS 15.8.6
  • iOS 12.5.8

Additionally, iPadOS updates included:

  • iPadOS 15.8.6
  • iPadOS 16.7.3
  • iPadOS 18.7.4

Purpose of the Updates

These updates aimed to ensure essential system functions remained operational on models that do not receive new major iOS releases. Specifically, they addressed issues that hindered some devices from making emergency calls.

Affected Devices

Apple’s update policy affects various iPhone and iPad models. The following iPhones are included:

  • iPhone SE (1st and 2nd generation)
  • iPhone 5s
  • iPhone 6, 6 Plus, 6S, and 6S Plus
  • iPhone 7 and 7 Plus
  • iPhone 8, 8 Plus, and X
  • iPhone XS, XS Max, and XR
  • iPhone 11 series
  • iPhone 12 series

The affected iPad models include:

  • iPad mini 2 and 3
  • iPad Air and Air 2
  • iPad mini 4
  • iPad Pro (9.7-inch and 12.9-inch, 1st generation)
  • iPad (5th, 7th, and 8th generation)

Update Status and Future Implications

Recent updates do not contain new features or address security vulnerabilities. According to Apple’s release notes for iOS 12 and iOS 15, the primary objective was to replace an expiring security certificate crucial for services like iMessage and FaceTime. Without this update, these services would cease functioning after January 2027.

Interestingly, Apple has not provided an explanation for stopping the signing process for these updates. Historically, Apple has restricted installations when bugs are uncovered and subsequently re-enabled updates once corrected versions are available. As of the latest reports, iOS version 26.2.1 remains available for download, suggesting no impact from this signing halt.

Network Issues and User Recommendations

After the signing halt, Telstra, an Australian telecommunications provider, reported an ongoing issue affecting older Apple devices’ connectivity, especially for emergency calls. They are collaborating with Apple to resolve this issue promptly and advise users not to update their software until a solution is confirmed.

As of the latest update, Apple is once again signing iOS 12.5.8, iOS 15.8.6, and iOS 18.7.4, allowing installations to resume. However, iOS 16.7.13 remains unsigned, indicating a limitation to this specific version. Filmogaz.com will provide further updates as more information becomes available.
