Auto-tsschecker: The easiest way to save the .SHSH2 signature for the Prometheus application to downgrade to unsigned iOS

As we reported earlier, tihmstar hacker announced that he plans to release a new tool called

Prometheus, which allows users to downgrade or upgrade more unsigned versions of iOS.

He also released a new tool calledtsschecker, which allows you to create and save the .shsh2 digital signature necessary for the Prometheus application to perform a downgrade or upgrade procedure for iOS that Apple no longer signs.



By itself, a way to save digital signatures.shsh was not entirely obvious to tech-savvy users. Fortunately, 1Conan, a Reddit user, intervened and created an online tool called AUTO-tsschecker, which can save you the trouble of running terminal commands, and instead automatically create and save for you .shsh2 signatures for the current version of iOS.

To use the online tool, you need the ECID and identifier of your iPhone, iPad, or iPod Touch.

  • Connect your iOS device to your computer.
  • Select the "Overview" tab in the left pane.
  • Click in the Serial Number field on the Overview tab until the ECID number appears.
  • Right-click on the number and copy it to the clipboard.

Please note that you needhexadecimal ECID value. If you send the decimal value to the ECID, it will not save the correct digital signature .shsh2. You can visit this site to convert the decimal value of ECID to hexadecimal.

So you don’t have to go through the hassle of manually creating a signature each time Apple releases its next update to its mobile operating system.
