Dumps onboard SHSH blobs with a valid generator for jailbroken iOS devices

extraire

extraire (verb): to extract

Simple program to dump onboard SHSH blobs with a valid generator for jailbroken iOS devices. Supports Windows, macOS and Linux.

What's this?

This program dumps the IMG4 ApTicket from /dev/disk1 on the device, copies it to your computer and converts it to a valid SHSH blob, no external dependencies required.

Even though the dumped SHSH blob is valid, you will still be limited by a few factors:

• SEP/Baseband/Rose firmware compatibility with the currently signed iOS version
• If you've updated to your current iOS version with the Settings app, you cannot use the dumped blob without a bootROM exploit (e.g. checkm8).

Requirements

OpenSSH Server installed on your jailbroken device. That's it!

Installation

From PyPI

pip install -U extraire

Standalone binaries

Standalone binaries for Windows, macOS and Linux can be found here.

You will need to allow executable permission for macOS and Linux after downloading. Run chmod +x /path/to/extraire in a terminal (replace /path/to/extraire with the actual path).
