Subject: Security Vulnerabilities, Exploitation Methods, and Deployment Mechanisms for Legacy 32-Bit Devices Target Firmware: iOS 9.3.6 Architecture: ARMv7 (32-bit)
The Hard Truth: There is no untethered jailbreak for iOS 9.3.6, and there likely never will be.
For the nostalgic user holding an iPhone 4s, the iOS 9.3.6 jailbreak experience is functional, stable (once booted), but forever tethered to a computer for the boot process. The golden age of untethered jailbreaks (iOS 5, 6, 7) is over. Adapt to semi-untethered, or lock your device and never reboot again.
