Why save blobs

Saving Onboard Blobs is the process of saving your previous signature from when you last updated, and converting that into a usable blob. Because you updated while the version was still signed, you can re-use these blobs, and they will still be valid.

However, the type of blobs that you save will depend on how you updated to your current version. These blobs require a bootrom exploit to be used, and only can be used with the --use-pwndfu argument in FutureRestore. However, they differ according to whether you restored or updated using a computer. If you restored using a computer, your blobs will be "Erase" blobs, and cannot be used with the "Update -u " option in FutureRestore.

If you updated using a computer, your blobs will be "Update" blobs, and can only be used with the "Update -u " option in FutureRestore. A popup will appear with the message "APTicket Submitted" once finished. You can now access your blobs on shsh.

First, you need to download the TSS checker zip file from Github or download it from the direct link. Now we use this to save blobs.

Please note, some devices have multiple models; you must know which one you have.

If you save blobs for the wrong model, they will be invalid and cannot be used. For example, iPhone 8 has a model identifier of iPhone10,1 or iPhone10,4, not iPhone8,x which is actually the iPhone 6s. You will know if you need to specify this property for your device because when you select your device type and model, a Board Config field will automatically appear on the page.

If you see it, you must enter your board config. If that box does not appear when you select your device type and model, you can skip on to the next step. If you specified an Apnonce in Step 9 , you can now optionally specify a Generator too.

If you do decide to specify one, it must be the same generator you set when jailbreaking your device during the process of finding your Apnonce.

The generator you set on your device when finding your Apnonce dictates the Apnonce you found; they are paired together. To save valid blobs, always use the same generator you used when finding its unique Apnonce. Submit the page to save your blobs. The next page that appears will give you a link to download the blobs, as you can see in the image below. I would recommend clicking through the link to save them immediately, though they should remain saved online for future retrieval as well.

On occasion, some blobs will not save immediately if the site is under heavy load. Future blobs are not automatically saved, so this process must be repeated for each new firmware version.
