How to Restore Unsigned IPSW on iPhone (Explained) - 2025 Why Some IPSW Files Are Unsigned Apple “signs” each iOS version to verify it’s safe for installation. Once Apple stops signing an older version, it becomes “unsigned,” meaning your iPhone won’t accept it anymore for security and stability reasons. Safe Way to Downgrade Use a tool like ReiBoot to check for still-signed firmware. It automatically lists all available versions and lets you downgrade safely — no jailbreak, no data loss. Why SHSH Blobs Don’t Work SHSH Blobs were unique digital signatures used in older iOS systems (pre–iOS 5). Since Apple introduced stronger encryption in the signing process, tools like FutureRestore have become unreliable for modern devices. Delay OTA Option Delay OTA allows a temporary upgrade to a slightly older iOS version just after it stops being signed, but only within a few weeks’ window. It’s not a downgrade method and works under very limited conditions. Best Advice Don’t rush system updates, and never try to install unsigned firmware using unsafe tools or jailbreak methods. Stick to verified downgrade tools like ReiBoot and check signing status on IPSW.me. 🤨Understanding Key Terms and Resources ●IPSW: The iOS firmware file used to install or restore Apple devices. It contains the operating system and recovery images. ●SHSH Blobs: Apple’s digital signatures tied to specific firmware and device combinations. They ensure only authorized versions of iOS are installed. ●Apple Signing Server: The authentication system that verifies IPSW files before installation, ensuring device integrity and preventing tampering. ●FutureRestore: A now largely obsolete tool that once used saved SHSH blobs to reinstall unsigned iOS versions. ●Delay OTA: A temporary method allowing users to install a recently unsigned iOS version if the OTA cache still exists. ●ReiBoot: A professional tool by Tenorshare that manages iOS system repair, firmware updates, and downgrades without data loss. 👇You might also want to know: Can We Downgrade iOS with Unsigned IPSW? - 2024 August | iOS Downgrade:   • Can We Downgrade iOS with Unsigned IPSW? -...   How to Install Unsigned IPSW Files on iPhone? 2024 New! | Downgrade to Unsigned iOS:   • How to Install Unsigned IPSW Files on iPho...   [Easy & Fast]How to Transfer Data to iPhone 17 from Any iPhone?
