This is a full in-depth guide to using Turdus Merula on Linux to perform a complete untethered downgrade on A9 and A9X devices with the help of saved SHSH blobs. This step-by-step tutorial walks you through the entire process of restoring your iPhone or iPad to any iOS version ever supported by these devices — no jailbreak required. Since this is an untethered downgrade, the downgraded iOS works normally and does not require a PC to boot every time. After the downgrade, all essential features — including SEP and installed apps — remain fully functional. The method shown in this guide is completely free for everyone.

Supported Devices:
iPhone SE (1st generation)
iPhone 6s
iPhone 6s Plus
iPad Pro 9.7-inch
iPad (5th generation)
