E. iOS-OTA-Downgrader (free)

• Script-based tool for checkm8-vulnerable devices (A5–A11: iPhone 4s to iPhone X).
• Can downgrade to certain unsigned iOS versions (e.g., iOS 10, 8, 6) without blobs for some devices.
• Linux/macOS only.

• What it does: User-friendly interface for unsigned restore using blobs or pwned DFU

• Requirements: Same as FutureRestore (blobs) or checkm8 (A5–A11)
• Limitations: GUI still requires technical steps (blobs, nonce, pwned DFU)
