FAQs About iOS 18 Downgrade
1. Is it possible to downgrade iOS?
Yes, you can downgrade iOS to a previous version signed by Apple. If you have upgraded your device to a version, you can easily downgrade to a stable version about a week or two after a new release.
2. How to install an older version of iOS?
There are many ways to undo an iOS 17 update on an iPhone. If you want, you can take the assistance of iTunes or Dr.Fone - System Repair (iOS) to do the same. If you have a jailbroken device, you can even give tools like TinyUmbrella a go.
3. Can I downgrade to an unsigned iOS?
Ideally, you can't downgrade your device to an unsigned iOS version. This is because the Apple server won't authenticate your downloading request without a valid SHSH blob. That is why users take the assistance of a previously saved SHSH blob to do the same. You can also use a third-party downgrading tool to do it as well.
4. What does a signed IPSW mean?
When we install an iOS version on the device, the Apple server asks for a digital signature to authenticate it. A signed IPSW file would have a verified signature issued by Apple, letting us upgrade/downgrade the device without any hassle. Therefore, if an IPSW file is not signed by Apple, then it will not be recognized by the server, and the upgrading/downgrading process won't be completed.
5. How to join and leave the Apple Software Program?
The Apple Software Program lets us test the releases of iOS before the public availability. You can join or leave the program anytime you want without spending anything. If you want to leave it, then go to the Unenroll section of the website.
6. How do I remove the software from my iPhone?
After downgrading an iOS update, you might find an existing software profile on your device storage. To remove this, just go to your device's Settings > General > Profile and select the iOS profile from here. Tap on the "Delete Profile" option and confirm your choice to remove it.
7. What are SHSH blobs for iPhone?
Both SHSH and SHSH2 blobs are referred to as digital signatures deployed by Apple on respective IPSW files. This protects the authenticity of the IPSW files, and only signed software would be installed on the device. When Apple releases a new iOS version, it stops signing the previous version. In this way, users need to upgrade to the latest public iOS version. This is where previously saved SHSH blobs are used to forge these signatures in order to downgrade our devices.
8. Can you save SHSH blobs after Apple stops signing?
You can restore a previously stored SHSH blob from your device or forge Apple's signature. There are a few third-party tools like FutureRestore that can help you do the same. You can also choose to dump your SHSH blobs in order to use them afterward. Though, in most cases, users have to jailbreak their iOS device in order to do it.
