How to save blobs for Apple TV?

 Hand in hand with the possibility of a jailbreak comes the necessity of saving blobs for your device, which will allow you to upgrade, downgrade, or restore your device at a later date, without worrying about signing windows. This guide will walk you through how to save blobs for your Apple TV.

As we have wrote how to back up shshs2 files for your iPhone, you can save as same processes.

1) Connect your Apple TV to your computer via USB-C or micro-USB. Open iTunes and select your Apple TV in the devices section.

2) Right-click the ECID field on summary page , which will be a string of letters and numbers, and copy it.

3) Paste the value somewhere safe on your computer.

4) Open a browser and go to the TSS Saver website by /u/1Conan. This is an easy-to-use interface for tihmstar’s TSS Checker, and can save .shsh2 blobs for all devices.

5) We will now fill in the form. First, paste the ECID you copied into the relevant field. Select the identifier for your Apple TV.  Leave the Manually specify an apnonce… field blank.

 The finished form should look something like this:

6) Hit the Submit button to send the request and save your Apple TV blobs.

7) Once saved, the following screen will appear with a download link for your blobs. You can copy it down for later and have your blobs saved online for you.

8) If you clicked the link to download now, it will now show you all the blobs you’ve ever saved for this device. 

Remember:

• Blobs can only be saved for a firmware that is currently signed by Apple. There is no trick to save them later. Save them as soon as a new firmware is out.
• Blobs are not transferable to other devices. They are unique and can only be used for your device.
• You do not have to update your device to a firmware to save blobs for it. It doesn’t matter what firmware you’re running, only what firmwares are signed.
• Go back periodically to save blobs for new firmwares as they’re released.

Going forward, if you have your blobs saved, you can use Prometheus to upgrade to whatever you want if new jailbreaks are released.
