[2024 Newest] How to Downgrade from iOS 17 to 16.6 without Data Loss

Part 1. Is It Possible to Downgrade iOS Version?

Yes, it is possible to downgrade the iOS version on an iPhone, but there are a few things to keep in mind:

• Apple does not allow downgrading to older iOS versions through standard means like OTA software updates. However, you can manually downgrade using iTunes and the IPSW file for the older iOS version.
• Downgrading requires that Apple is still signing the older iOS version. Apple stops signing older versions about 1-2 weeks after releasing a new update.
• The downgrade process involves a full restore, so you'll want to properly back up your iPhone data first. As long as you restore from this backup, you won't lose data.
• Certain iOS versions may no longer be compatible with or fully supported by the latest apps and services. So carefully consider if reverting back to an earlier iOS makes sense.
• Devices like the iPhone X and later require a Mac computer to downgrade iOS as they cannot connect to iTunes on Windows PCs.
