What is the iOS Signing Status (TSS)?

Apple signs only a few iOS versions at a time, and usually the latest builds. This is to prevent users from freely downgrading to older iOS versions and jailbreak. Once a new iOs version is released by Apple, the previous 1-2 versions may stay signed for a few more days or weeks before getting unsigned.

Once an iOS version has been unsigned, it’s not possible to downgrade or upgrade to it anymore unless you have saved SHSH2 blobs while it was still signed, SEP and Baseband are compatible, and there’s a way to set a Nonce Generator on the version you’re currently running.

On this website, you can monitor the changes in the signing of all iOS versions for all devices, including iPad, iPod Touch and iPhone. Apple does not post anywhere when they sign a version, so if you wanna downgrade to a specific version, make sure to check here if it’s still signed first.

Note: The data on this website is updated in real-time. Once a new iOS version is released or an older one stops being signed, the data is updated in minutes thanks to the API used.

Proven Ways to Restore Unsigned IPSW

Apr 18, 2021 (Updated: Nov 15, 2021) • Filed to: Downgrade iOS

6K views, 7 min read

As Apple releases new iOS software versions, it also stops signing some older versions. This means sooner or later, your current iOS version will no longer be supported, and you may have to upgrade to a newer iPhone firmware version.

But every iOS update comes with its downsides. While the 14.4.2 version update fixes some performance issues introduced by earlier versions, the update also caused new problems like short battery lifespan, iPhone freezes, and charging issues.

One way to solve update-related issues on iOS is to move back to a known stable version, in other words, downgrade to unsigned iOS version. But what if Apple has stopped signing a version you intend to move back to? You might be wondering whether it’s possible to restore unsigned IPSW of that said version. Regardless of what you think, let’s find out.

Is It Possible to Restore To Unsigned IPSW?

Yes, you can restore your iOS device to an unsigned IPSW firmware, but not in the traditional way. Usually, when you want to upgrade or downgrade to an iOS version using the IPSW restore file, you will do so through iTunes.

During the downgrade process, iTunes will make some verifications and checks with Apple servers to ensure you are restoring a signed IPSW file. Anyone trying to work with unsigned IPSWs firmware will only get you an error message.

To upgrade or downgrade to a previous iOS firmware that has stopped being signed by Apple, part of the requirements are a third-party restore app, the destination unsigned iOS IPSW file, and its SHSH blob file. You will learn more about these requirements in this blog. So keep reading.

What is Unsigned IPSW?

IPSW is the file extension of Apple’s iPhone mobile operating system. An unsigned IPSW means Apple has stopped supporting the iOS version. iOS users wouldn’t be able to use iTunes to restore to an unsigned firmware.

Apple periodically unsigns iOS version because of security issues and to encourage users to make use of additions newer updates have to offer.

Regardless of the reason and as we mentioned earlier, new versions of iOS software often cause unpleasant experiences to device performance and features. To resolve firmware update bugs and issues, reverting to a previous stable iOS version might be the solution.

Restore Unsigned IPSW Using SHSH2 Blobs

You learned earlier that it is possible to restore unsigned IPSWs with the help of SHSH2 Blobs. These blob files are the digital signatures that Apple places on each IPSW firmware file for each iOS device. When Apple stops signing a particular firmware, it removes the sign (signature) from the firmware so users won’t be able to upgrade or downgrade to it.

Note: You must have saved a blob (digital signature) file of the iOS version you want to restore while the version is still being signed by Apple. Once Apple stops signing an iOS firmware version, the signature is removed, and then, you can’t restore the firmware.

Online tools like TTS Saver can help with blob saving. You can start saving the digital signature of your current iOS firmware now for possible future use. For how to save and restore SHSH2 blob files, see the steps below. You’ll find this useful when restoring iOS.

Step 1: Connect your iPhone to your Mac or Windows computer using a data transfer cable.

Step 2: Open iTunes on your PC and navigate to the iPhone device information page by clicking the mobile icon at the top screen. Keep clicking on Serial Number until ECID appears. Copy the value next to it.

How to Save SHSH2 Blob File Using TSS Saver

Step 3: Go to this website. Enter your ECID, choose your iPhone model and click «Submit«. The online tool will automatically save the blob of all available iOS firmware for your iPhone device and provide you with an option to download any of them.

Step 4: Referring to the image below, insert your ECID value and click submit to see all blob files you’ve previously saved.

With your blob files ready, you’re only halfway through completing how to downgrade to unsigned iOS. That said, follow the instructions in the next section to discover how to use FutureRestore to complete unsigned iOS restore.

Restore Unsigned IPSW by FutureRestore

FutureRestore is a tool developed for iOs users who want to restore, upgrade, or downgrade to any iOS version that is no longer signed by Apple. But FutureRestore can’t do the job alone. It needs the help of other files — the destination unsigned iOS IPSW file you’re moving to and the blob file of that said destination iOS firmware.

To downgrade to unsigned IPSW file using FutureRestore, follow the steps below:

Requirements:

A more recent version of the Futurerestore.

The IPSW file of the unsigned iOS you’re restoring to.

The blob file of #2 (which you’ve learned how to save and retrieve in the previous section).

With all these requirements set, continue with the instructions below.

Step 1: Connect your iPhone to your PC, making sure your PC has an Internet connection.

Step 2: Put all the 3 items listed in the requirements into one folder.

Step 3: Open up Terminal on your Mac computer or Command Prompt (for Windows users).

Step 4: Drag the unarchived FutureRestore file into Terminal and type -t.

Step 5: Next, drag the blob file into the Terminal interface and type —latest-sep —latest-no-baseband (if your iPhone is not sim-enabled) or —latest-sep —latest-baseband (if your iPhone uses sim).

Step 6: Drag the unsigned iOS firmware into the Terminal screen as well. After performing steps #4 through #6, your terminal or Command Prompt interface should look like the one in the image below.

Step 7: Press enter and let the downgrade process begin and complete.

Step 8: If the log on the Terminal screen indicated that the process is stuck and failed at recovery mode, simply reenter the line of codes and try again.
