How to Use SHSH Blobs to Downgrade iOS Safely

Part 1: What SHSH Blobs Are and How They Work

SHSH blobs are Apple's signed authorization records for a specific device and firmware build. When a downgrade works with blobs, it is because the restore can still be authenticated for that exact combination.

That compatibility chain usually includes the target IPSW, a supported device, and the SEP/baseband combination that the restore path accepts. If any of those pieces do not line up, having the blob alone is not enough.

That is why searches such as shsh, what is shsh blobs, and how to use shsh blobs to downgrade iOS usually break into two separate jobs: defining the term, and deciding whether a real downgrade path still exists.

Part 2. How To Save SHSH Blobs Using Current and Legacy Methods

If you searched for download shsh or shsh host, what you usually need is a blob saver or host workflow, not an IPSW download. Save the blob as soon as you can, because the signing window can close before you need it.

For most readers, TSS Saver is the easiest current starting point. Community host workflows such as shsh.host can also be useful, while older tools like RedSn0w, shshd, and iFaith are mainly legacy-only.

Method 1: Save SHSH Blobs With TSS Saver

One of the simplest ways to save SHSH blobs is by using the TSS Saver website. Follow these steps:

• Step 1: Open your browser and go to TSS Saver. Find your device's ECID, then copy it exactly from Finder, Apple Devices, or iTunes, depending on your setup.

• Step 2: Enter the ECID and your device model, then save the generated link or blob record for future use.

Method 2: Legacy blob-saving workflows

Legacy only: RedSn0w-era workflows are mainly relevant to older hardware and archived jailbreak setups. If you are working with a legacy device, follow the exact device-specific instructions instead of treating this as a modern default path.

• Step 1: Open the legacy tool and choose the SHSH blobs option from the extras or advanced menu.
• Step 2: Put the device into DFU mode when the tool asks for it.

• Step 3: Let the tool finish the legacy fetch or save flow for that device.

Method 3: Save Blobs via shshd

shshd is a jailbreak-era tweak for automatic blob saving. It is useful only if your device is already in a legacy jailbreak workflow and you want the process to happen in the background.

Instructions: Open your package manager, search for shshd, install it, and finish the prompt. The tool will handle blob saving automatically for that legacy setup.

Method 4: Save SHSH Blobs via iFaith

For older iPhone models, iFaith can still be useful as a legacy Windows-only tool. It is not a modern default path, but it remains relevant for some older devices.

• Step 1: Install and launch iFaith on your Windows computer. Click Dump SHSH Blobs and choose Proceed on the next screen.

• Step 2: Connect the device, put it into DFU mode, and start the capture process. When the blobs are captured, save them to a location you can find later.

Part 3. How To Use SHSH Blobs To Downgrade an iOS Device

Use this route only when you already have valid SHSH blobs for the exact firmware you want and the restore chain is still compatible. The exact FutureRestore command varies by device, so follow the current documentation for your model instead of copying old flags from an outdated post.

• Step 1: Put the target IPSW, the SHSH2 blob, and any required restore files in one folder so you can point FutureRestore at them cleanly.
• Step 2: Open Terminal on Mac or Command Prompt on Windows and prepare the current FutureRestore command for your device.

• Step 3: Add the SHSH2 blob and the target IPSW, then include any signed SEP or baseband components that your current restore path requires.
• Step 4: Run the command and keep the device connected until the restore completes.

If the target build is no longer signed and the blob, SEP, or baseband combination does not line up, the restore will fail. That is a compatibility limit, not a missing-click problem.

Part 4. Downgrading iOS Devices Without SHSH Blobs

If you do not have SHSH blobs, the manual FutureRestore path is not available. The simpler alternative is Dr.Fone - System Repair (iOS), which gives you a guided upgrade or downgrade flow from the System Repair module.

The current Dr.Fone guide routes you through System Repair > iPhone > iOS Upgrade/Downgrade > Downgrade iOS. The official product page says it can repair iOS issues and perform upgrade or downgrade without iTunes or jailbreak, and the guide asks you to back up first before continuing.

• Step 1: Opt for System Repair in Wondershare Dr.Fone

After installing and launching Wondershare Dr.Fone, access System Repair through Toolbox.

• Step 2: Select the Device Type to Repair

Now choose iOS and click iOS Upgrade/Downgrade on the next screen.

• Step 3: Select Downgrade iOS

Select Downgrade iOS from the two options.

• Step 4: Backup iDevice

A prompt will appear asking you to back up your iOS device data before you continue.

Essential Backup Before iOS Downgrade

Tips: To avoid data loss during iOS downgrade, use Dr.Fone - Phone Backup (iOS) for a full, secure backup of your iPhone. This tool lets you selectively export contacts, photos, messages, and more before you downgrade.

• Step 5: Connect iDevice with USB Cable

You will then be asked to connect your iDevice with a USB connection.

• Step 6: Get Your Desired iOS Firmware

It will show the list of available firmware. Click Download to get the firmware you want.

• Step 7: Perform the Downgrade Process

Wait for the firmware download to finish. When it is complete, click Repair Now to start the downgrade.

• Step 8: Successfully Downgrade Your iOS Device

The process can take some time. When it is done, click Done.

If your firmware is not signed, switch back to the blob-based route. Dr.Fone does not bypass Apple's signing rules.

Part 5. FAQ

What are SHSH blobs?

They are Apple signing records for a specific device and firmware version. They help authenticate a restore when the rest of the downgrade chain is still compatible.

Can you downgrade iOS without SHSH blobs?

Not through the manual FutureRestore path. If the target firmware is signed, a guided tool such as Dr.Fone - System Repair (iOS) is the simpler route.

Why does shsh.host sometimes fail?

Because it is a community workflow, availability and behavior can vary. When it fails, check the ECID, the device pairing, and the current instructions for that exact setup.

Do I need to back up before downgrading?

Yes. A downgrade can erase data, and the official Dr.Fone guide also prompts you to back up before you continue.

Conclusion

In summary, SHSH blobs are useful when you already have the exact device and restore chain you need. If you have valid blobs, FutureRestore is the manual path. If you do not, the simpler option is a signed downgrade route such as Dr.Fone - System Repair (iOS), with a backup first.

The practical rule is simple: save blobs early, verify compatibility before you restore, and do not assume a blob alone makes every downgrade possible.
