How to Save Your iPhone’s iOS 11.1.2 SHSH blobs in 3 Easy Steps Before Apple Stops Signing Firmware


Downgrade iOS Firmware

Security researcher Ian Beer announcement that he plans to release the iOS 11.1.2 exploit has raised hopes of a jailbreak for iOS 11.1.2 or lower. If you want to jailbreak iOS 11, then you should downgrade to iOS 11.1.2 while Apple is still signing the iOS 11.1.2 firmware file.

It is also a good practice to save SHSH blobs, so you can use tools like Prometheus tool (when it is updated for iOS 11) to downgrade to iOS 11.1.2 when Apple stops signing iOS 11.1.2 firmware file.

You can use the TSS Saver online tool to save your iPhone, iPad or iPod touch’s SHSH2 blobs. To use the online tool, you need your iPhone, iPad or iPod touch’s ECID and device identifier.

You can follow these 3 steps to save SHSH blobs for iOS 11.1.2 before Apple stops signing iOS 11.1.2 firmware file.

STEP 1: Get ECID

  • Plug your iOS device to the computer.
  • Launch iTunes and click on Summary in the left-hand pane.
  • Click on the Serial number field in the Summary tab until you see the ECID.
  • Right-click on it and copy it to the clipboard.

STEP 2: Get Device Identifier

  • Just like the ECID, click on the Serial number field in the Summary tab in iTunes until you see the Model Identifier. E.g. in the case of iPhone X, it the model identifier will be iPhone10,6.

STEP 3: Save iPhone SHSH Blobs

  • Open the following link: https://tsssaver.1conan.com
  • Paste the ECID you had copied above.
  • Select your device type i.e. iPhone, iPad or iPod touch.
  • Next, enter your iOS device’s identifier which you had found in step 2.
  • Click Submit.

That’s it. It will take you to the result’s page, and give you the link to your saved .shsh2 blobs. Save the link given somewhere. In case you lose your link, you can get download your .shsh2 blobs again by visiting https://tsssaver.1conan.com/shsh/<decimal ECID here> (you can convert the HEX ECID to decimal first using this website). While saving the SHSH blobs for my iPhone X, I realized that Apple is still signing iOS 11.1.1 firmware file, along with iOS 11.1.2 and iOS 11.2 firmware files.

The best part of the method is that it will save the .shsh2 blobs automatically for you for any new iOS version Apple may release in the future, so you don’t have to go through the hassle of saving it manually every time Apple releases an update.
