Future Downgrade: How to Save iOS 19/26 SHSH Blob

Part 1. Can You Use SHSH Blobs With iOS 19/26 Beta?

Yes, you can. SHSH When you update or restore your iPhone, Apple checks SHSH Blobs to make sure you’re installing a signed, official version. Normally, Apple only signs the latest iOS, which blocks downgrading to older versions. In the past, people used to save blobs with tools like shsh.host to bypass Apple’s signing window to downgrade to earlier iOS versions and install unsigned IPSW.

This was often done for jailbreaking. But now the functionality of shsh.host is questionable, and there are other better tools that can perform the same task. You can use TSS Saver and BlobSaver to get iOS 19/26 Beta SHSH Blobs download APK, if you’re testing Beta software.

Part 2. How to Download or Save iOS 19/26 Beta SHSH Blobs?

TSS Saver and FutureRestore are two popular tools you can use to download SHSH blobs or save them for downgrading iOS 19/26 Beta. Here’s a step-by-step guide to using them, along with each tool’s advantages and limitations:

#1 Using TSS Saver (Online Tool)

TSS Saver is very easy to use from any web browser and doesn’t need much tech knowledge to save blobs. However, it only saves blobs and can’t restore or downgrade your device. Also, you have to save blobs while Apple is still signing the iOS version. Before using TSS Saver, you’ll need to find out your device’s ECID, which is its chip ID and its model identifier. Afterward, you can download blobs. Here’s how to use TSS Saver:

• Connect your device to your computer. Then, open iTunes (Windows) or Finder (macOS). Head to the device summary.
• Click the “Serial Number” until ECID appears, then copy it. Next, find your device’s exact model. Find it in “Settings” > “About.”


• Head to “tsssaver.1conan.com.” Paste your ECID into the correct field (no extra spaces). Then, select your exact device model from the dropdown.

• Check if iOS 19/26 Beta is listed under available signed versions. Click “Submit” or “Save SHSH.” After submission, you’ll get a link to your saved blob.

• Bookmark this link for future access. Download the “.shsh2 file” shown. Save it in a clearly named folder (e.g., “iPhone 15 Pro Max Blobs”).

#2 Using FutureRestore or BlobSaver (Desktop Tools)

FutureRestore is a powerful tool for upgrading or downgrading iOS using saved SHSH blobs, giving you more control over the iOS version you install. However, it can be complicated to use and needs compatible SEP and baseband files to function properly.

Whereas, BlobSaver is a tool that saves SHSH blobs for you, which is important if you plan to use FutureRestore later. But it doesn’t actually restore or downgrade your device, but just prepares the files you'll need. Here’s how to use BlobSaver to save SHSH Blobs:

• Head to “BlobSaver GitHub Releases.” Download the version for your OS (Windows, macOS, or Linux).

• To install BlobSaver on Windows, extract the ZIP and run “blobsaver.exe.” Click “More info” > “Run anyway” if SmartScreen appears.
• When BlobSaver opens, click “Read from Device” next to ECID. The tool will automatically identify your device’s ECID and model.
• Check “Include Betas.” If your device is an A12 model, tap “Read from Device” next to APnonce. Your device will reboot into Recovery Mode.

• Hit “Go.” BlobSaver will contact Apple’s servers and download the blob. Saved “.shsh2 file” will be stored in your selected folder.

Part 3. How to Use SHSH Blobs to Downgrade iOS 19/26 Beta?

Downgrading from iOS 19/26 Beta to an unsigned iOS 18 is nearly impossible on newer devices (A12 and up) due to SEP and nonce issues—both require compatibility and often a rare jailbreak or exploit.

On older devices (A11 and earlier) with the checkm8 exploit, you can use FutureRestore to downgrade—if the SEP and baseband match and you can set the correct nonce with a jailbreak.

• Download FutureRestore. Execute it. Tap “Select Blob” file for iOS 19/26 Beta. Then, get the IPSW file for iOS 18 from ipsw.me. Hit “Select Target IPSW File.”


• Click “Next.” Connect your iOS device to a computer. Tap “Start FutureRestore.” The tool will flash the firmware.


• You’ll get a done message when your iOS is downgraded.

Part 5. People Also Ask About iOS 18 SHSH Blobs

Q1: Can I use someone else’s SHSH Blobs?

No. You can’t use someone else’s SHSH blobs because they're made specifically for one iPhone and one iOS version. They’re like a unique fingerprint tied to your device, so they won’t function on another iPhone.

Q2: Can I downgrade without SHSH blobs?

Yes, you can with Tenorshare ReiBoot, which doesn’t require SHSH Blobs, iTunes, or jailbreak to downgrade iOS.

Q3: What’s the difference between OTA blobs and full blobs?

Full blobs are created during a full iTunes restore and include everything needed for a complete downgrade, making them ideal for tools like FutureRestore. Whereas OTA blobs come from over-the-air updates, are smaller, and lack key components, so they’re more limited for downgrading.

Final Word

Downgrading from iOS 19/26 Beta to iOS 18 using SHSH blobs is complicated, especially on newer devices (A12 and up), due to issues with SEP and nonce compatibility. Tools like TSS Saver and BlobSaver can help in iOS 19/26 Beta SHSH Blobs download. While FutureRestore can be used to downgrade iOS using the blobs on some older devices.

But the process often requires jailbreaks and exact file matches, making it easy to mess up. For a simpler option, Tenorshare ReiBoot is much easier to use. It has a user-friendly interface and lets you downgrade to iOS 18 in just a few clicks without SHSH Blobs, iTunes, and jailbreak.
