1.1 What is Blobsaves?

Blobsaver is a tool that allows iOS users to save SHSH2 blobs for their devices. SHSH2 blobs are unique cryptographic signatures that are specific to each device and iOS version combination.

When Apple releases a new iOS version, they stop signing older versions after a while. This prevents users from downgrading their devices to those older iOS versions.

However, with SHSH2 blobs saved for a specific iOS version, it is possible to bypass Apple's signing restrictions and downgrade a device even after Apple stops signing that iOS version.

1.2 What's the Feature of Blobsavers?

Here are some of the key features of Blobsaver:

Automatic background saving of blobs - Blobsaver can automatically detect new iOS versions in the background and save blobs without any user interaction needed.
Reads APNonces and generators - On both jailbroken and non-jailbroken devices, Blobsaver can read the APNonce and generator, which are required for saving valid blobs.
Unlimited device storage - There is no limit to the number of devices you can save blobs for with Blobsaver.
Beta version support - Blobs can be saved for iOS beta versions without needing to specify any URLs.
Background saving for betas - Beta blob saving also occurs automatically in the background.
CLI automation - All Blobsaver features can be automated via the command line interface.
Integration with blob services - Blobs can be easily saved to services like TSS Saver and SHSH Host with one click.
ECID reading - Device ECID is read by Blobsaver for identifying devices.

1.3 What Is Blobsaver For iOS?

Blobsaver for iOS is an application that allows users to save SHSH2 blobs for their iPhone, iPad, or iPod Touch.

SHSH2 blobs are unique signatures that are specific to a device and iOS version combination. They allow downgrading or upgrading to unsigned iOS versions.

Apple only allows upgrading/downgrading to iOS versions that it is currently digitally signing. Saving blobs with SHSH Blob Saver circumvents this limitation. With the blobsaver downloaded on your system, you can easily downgrade to the previous iOS.

1.4 Does Blobsavers Work?

Yes, Blobsaver does work to save valid SHSH2 blobs that can be used to downgrade or upgrade iOS devices.

Numerous users on jailbreaking communities like r/jailbreak have reported success using Blobsaver-saved blobs to downgrade their devices to unsigned iOS versions.

Blobsaver leverages dedicated blob saving tools like img4tool to save blobs correctly. These tools have been vetted and confirmed to work by the iOS downgrading community.

The app actively reads device-specific parameters like ECID directly from the device before saving blobs. This ensures the blobs are tailored and valid for that specific device.

1.5 How to Use Blobsavers?

Here are the steps to use Blobsaver to save SHSH2 blobs:

1. Download blobsaver online for your operating system (Windows, macOS, Linux) and install it on your computer. Launch the blobsaver windows.

2. Connect your iPhone or iPad to your computer using the original USB cable. On your device, tap "Trust" if prompted to allow the connection.
3. Prepare for blob saving. Your current iOS version doesn't need to match the target iOS 17.
4. Identify your device's ECID by pressing "Read from Device" in BlobSaver. This will automatically detect the ECID.
5. In the iOS section in BlobSaver, check "Include Betas" and press "Read from Device" on the APNONCE field if you have an A12 or newer device.
6. BlobSaver will now reboot your device into Recovery Mode to fetch the APNONCE.
7. Finally, press the big "Go" button in BlobSaver to start the blob-saving process and wait for it to complete.
8. Once finished, your SHSH2 blobs for iOS 17 will be saved for your device. You can now use them to downgrade in the future.
