- This may be due to USB connection issues, if you encounter this, start over from the beginning.
Restoring to iOS 10 may result in your device getting stuck in recovery mode.
- If you encounter this issue, restore to iOS 10.3.3 first, then downgrade to your target version.
Restoring to iOS 9 from a higher version may result in a restore failure.
- If you encounter this issue, restore to iOS 10.0 - 10.2.1 first, then downgrade to iOS 9.
Restoring to a version that is too old using pre-installed blobs may fail.
- Perform a tethered downgrade first, then retry the untethered downgrade.
Restoring any device using pre-installed blobs from factory may not restore baseband correctly.
- Baseband features or activation may not work.
- Tethered restores may work fine.
iOS 10 - 11 may fail to boot when restoring or tether booting, getting stuck on "recfg done".

Frequently Asked Questions

Q: What is turdus merula?
A: turdus merula is a tool that allows you to downgrade your iOS/iPadOS device to any version you want, tethered or untethered (A valid SHSH blob is required for untethered downgrades).

Q: What is a SHSH blob?
A: SHSH blob is a file generated by Apple that signs a specific iOS/iPadOS version. It can only be obtained while Apple is still signing that version. SHSH blob is required for untethered downgrades and are uniquely tied to each device.

Q: What is the difference between tethered and untethered downgrades?
A: A tethered downgrade requires connecting the device to a computer every time it boots, but it does not require a valid SHSH blob. An untethered downgrade functions like a normal system boot without requiring a computer, but it does require a valid SHSH blob.

Q: What devices are supported?
A: Devices with A9 to A10X chips running iOS/iPadOS are supported. Devices with A11 and later chips are not supported.

Q: What iOS/iPadOS versions are supported?
A: All iOS/iPadOS versions that the supported devices have previously run are supported. Note that tethered downgrades may have a more limited range of supported versions.

Q: How does this differ from futurerestore?
A: futurerestore requires a compatible SEP to work, which restricts which iOS/iPadOS versions you can downgrade to. turdus merula does not have this limitation and thus supports all iOS/iPadOS versions.

Q: Will turdus merula ever be open-source?
- LGPL sources are here >> libirecovery libfragmentzip libimobiledevice libimobiledevice-glue libplist libtatsu libusbmuxd idevicerestore
- Module objects built into idevicerestore are available here >> resource.tar.zst

Q: Where can I find the usage instructions?
A: Here

Q: How should I report a discovered issue?
A: Please report it here: GitHub Bug Tracker

Q: Is there a comprehensive user guide available?
A: The detailed user guide can be accessed here.
