iOS Signing Status for iPhone & iPad
What is iOS Signing and Why It Matters?
Apple signs specific iOS versions to control which firmware users can install on their devices. This signing process verifies that the version is supported, secure, and optimized for your iPhone or iPad. Once Apple releases a new iOS version, older versions are often unsigned after a few weeks. Once a version is no longer signed, it becomes impossible to install or downgrade to that version unless you’ve saved SHSH2 blobs for that firmware.
The importance of iOS signing lies in ensuring that devices are always up to date with the latest security patches, performance enhancements, and bug fixes. It also helps Apple limit exploits that hackers can use to jailbreak older iOS.
How to Check iOS Signing Status in Real-Time?
Tracking the real-time signing status of iOS versions is essential if you’re planning a downgrade or restore to a previous version. You can easily check which iOS versions are still signed by visiting websites that provide this data through TSS servers. Tools like TSSstatus or the ONE Jailbreak iOS Signing Status monitor Apple’s signing servers and give real-time updates on which versions are signed for iPhones, iPads, and iPods.
Understanding SHSH2 Blobs (iOS Downgrades)
SHSH2 blobs are unique digital signatures that Apple generates for each iOS device when installing or upgrading firmware. These blobs are essential if you plan to downgrade your iOS version. They act as certificates that validate your device’s firmware with Apple’s servers during installation. Without SHSH2 blobs, you can’t install unsigned iOS on your device.
Saving SHSH2 blobs for an iOS version allows you to downgrade even after Apple has stopped signing that version, provided you have saved the blobs when the version was still being signed.
