iOS 26 Beta SHSH Blobs Download: What You Need to Know

Part 1.The Overview of iOS SHSH Blobs?

1.1.What Are SHSH Blobs?

Apple relies on Secure Signature Hash blobs (SHSH blobs) to determine which iOS versions are compatible with a device. Whenever you update or restore your iPhone, it talks to Apple’s servers. Apple sees if the needed iOS version is still being signed. If the answer is yes, the server provides the SHSH blob, which enables the update or restore process to proceed.

No two devices have the same blobs, and they can vary depending on the iOS version. You are not allowed to use somebody else’s SHSH blobs. The relationship is built with your iPhone’s unique ID and the software version it is running. The signing process will produce SHSH blobs, and you will need them again if you ever need to restore the device with that version.

When you do not have SHSH blobs, you can only install the iOS releases that Apple is currently signing. If Apple stops signing, there is no approved method to revert to an older iOS version without SHSH blobs.

1.2 Why Are They Important?

SHSH blobs enable users to revert to an older version of iOS that Apple no longer supports. If you wish to get back to a jailbreak-friendly and secure version, this is very useful.

If iOS 26 has glitches and you want to revert to iOS 18.5, Apple will prevent it unless you have the SHSH blobs from iOS 18.5. Having them saved allows you to use the iOS version you chose without restriction once Apple shuts the signing window.

Part 2. Step-by-Step Guide on Saving & Using SHSH Blobs

Before downgrading or keeping your iPhone ready for jailbreak, the first step is to store your SHSH blobs. It should be done while Apple is allowing the firmware version to be signed. Once the signing window closes, it is no longer possible to save them. Below, you will find a clear explanation of the steps.

2.1 How to Save SHSH Blobs

You need to find your ECID and model identifier to save SHSH blobs. Using TSS Saver is very easy, as it does the job for you at no cost. Here’s the process for it.

2.1.1 Save SHSH Blobs with TSS Saver

• First, attach your iPhone to your laptop or desktop and start iTunes or Finder.
• Press the name of your device to open its information. Choose your device model after obtaining the ECID (a unique identifier).
• Go to the TSS Saver site (e.g., https://tsssaver.1conan.com/) to start the process.
• Copy and paste your ECID, then select the correct identifier from the dropdown menu.
• Select Submit. It will start saving your SHSH blobs.
• After finishing, you will receive a URL that allows you to download the saved SHSH blobs on your device at any time.

Always protect the URL you are given. You will rely on those blobs when you want to restore or downgrade your device.

2.1.2 . Save SHSH Blobs via RedSn0w

RedSn0w, which is an old but popular jailbreaking tool, can also be used to back up SHSH blobs through Cydia. This way is most helpful for users with older iOS devices who want their blobs safely stored on Cydia. You can do it this way using a Windows computer.

• The first step is to create a new folder on your desktop and name it 'Pwnage'. Download RedSn0w, unzip the file and put it in the same folder. Place the file in the same location as the original.
• Right-click on the RedSn0w executable and pick Properties from the options. Set the game to be compatible with Windows Vista and run it as an administrator (if you have Windows 7). The next step is to open RedSn0w.
• Open the Cydia app, tap on Extras, and from the next screen, select SHSH blobs.
• Click on Fetch to get SHSH blobs right from your device and upload them to Cydia.
• After that, link your iPhone to your PC and turn it off. Move forward by clicking Next and performing the actions RedSn0w shows to put the device in DFU mode.
• To enter the DFU mode,

○ Hold Power + Home for 10 seconds.

○ Release Power but keep holding Home until RedSn0w detects the device.

• RedSn0w will reboot your iPhone and then fetch the blobs. Once the SHSH blobs are saved, Cydia will confirm the process.
• Return to the SHSH blobs menu and select 'Query' at this step. Enter an asterisk (*) in the ECID field to see a list of all your devices. At this point, RedSn0w will display all the SHSH blobs stored on the Cydia server.

Having your device in this state guarantees that you can downgrade if you ever need to.

2.2.How to Use SHSH Blobs:

To use SHSH blobs, you have to use them with the same iOS device that saved them. Such blobs let you install or restore an iOS version that Apple no longer supports. When you have SHSH blobs, you can safely downgrade to an earlier firmware version or reinstall it. They guarantee the system checks if the firmware is genuine. Matching blobs is important since if they are missing, your device won’t accept the installation, which is useful for controlling or rolling back your firmware version.

Part 3. How to Downgrade iOS Using SHSH Blobs (Data will be Lost)

If you have SHSH blobs for an older iOS version, you can go back to that version by using the FutureRestore tool on iOS 26 (or any newer beta). This still functions when Apple no longer signs the old version. But since this will delete everything on your device, be sure to back it up before you start.

Let’s go through it step by step now:

Step 1: Connect Your Device

Attach your iPhone, iPad or iPod Touch to the computer with a USB cable. Then, on a Mac, open Terminal or Windows, open Command Prompt (CMD).

Step 2: Add Future Restore Tool

Drop the FutureRestore file into the Terminal or Command Prompt window by dragging it there. Now, the system knows how to run the tool.

Step 3: Specify SHSH Blob Use

Enter a space and then -t, to tell FutureRestore you are using an SHSH blob.

Step 4: Add SHSH Blob File

Place your SHSH blob file (which you have stored) into the Terminal or CMD by dragging and dropping it. It creates the blob’s movement path.

Step 5: Choose the Right Flags

This will depend on what kind of device you use:

• For devices with a SIM card:
• Type --latest-sep --latest-baseband
• For Wi-Fi only devices:
• Type --latest-sep --latest-no-baseband

Step 6: Add the IPSW File

Use your mouse to drag the unsigned IPSW file (for the iOS version you want to install) into the Terminal or Command Prompt window.

Step 7: Start Downgrade

Verify that the file paths and flags are configured correctly. When you have finished, press the Enter key. The first stage of downgrading the account will start. Do not take out the device’s battery or USB cable until you have finished the update.

Result:

After all the steps are done, your phone will restart on the downgraded version of iOS. All your past data will no longer be on the phone. Restoring from a backup is now possible if required.
