TSSSaver is an online tool that uses TSSChecker to save SHSH2 blobs for an iOS firmware that is being signed by Apple. Saving blobs for a firmware gives you the opportunity to upgrade or downgrade to that firmware once it is no longer being signed.
The tool was recently updated to fix an issue with the iPhone 7 and iPhone 7 Plus. Today’s update to TSSSaver brings another new feature. You can now use it to verify if your SHSH2 blobs are valid or not.
How to Verify SHSH2 Blobs with TSSSaver
Step 1: Open this link on your computer.
Step 2: Upload the SHSH2 blob and choose the iOS firmware and device model.
Step 3: Click on the Submit button.
Step 4: If the Build Configuration is correct and Rosi Tag is ‘true’, then it means that the SHSH2 blob is valid. You can check the build configuration of your device model from here. Look for the column called ‘Internal Name’.
Ensuring that your SHSH2 blob is valid for a specific firmware is important because if Apple stops signing it and the blob is invalid, then it won’t be possible to regenerate it. SHSH2 blobs can only be generated for firmwares that are still being signed by Apple.
This new update to TSSSaver will help you ensure that all the blobs you’ve saved with it are valid. It is good to see that the tool is receiving constant updates to improve and fix any issues that are found.
