• usbmuxd on Linux systems

Notes

• deleo only supports 64-bit devices.
• In most cases, you can only restore using a signed 15.x or below IPSW as latest.
  • More info on that <a href="https://gist.github.com/Cryptiiiic/b82133ac290070939189e1377dc3ac85">here</a>.
• In place of an actual IPSW file in the IPSW or LATEST_IPSW arguments, you can pass a URL to an IPSW instead.
  • This is not recommended for the IPSW argument, as downloading the RootFS dmg directly from the ZIP will take quite a while...
• Ensure that whatever version you are restoring to is compatible with the SEP version in the latest IPSW.
  • You can find a spreadsheet that will show you what iOS versions are compatible with the latest SEP version <a href="https://docs.google.com/spreadsheets/d/1Mb1UNm6g3yvdQD67M413GYSaJ4uoNhLgpkc7YKi3LBs">here</a>.
• On Linux systems that utilize udev, you may need to install proper udev rules to have proper access to connected *OS devices
  • Typically, you only need to install libirecovery from your distribution's package manager.
  • Alternatively, you can download a rules file provided <a href="https://gist.github.com/m1stadev/c0c9313c37a2ed42ceb71903a5102677">here<a/>, and place it in /etc/udev/rules.d
  • Once the rules file is installed, reboot to ensure that the rules file is detected properly.

Installation

• Install from PyPI:
  • python3 -m pip install deleo
• Local installation:
  • ./install.sh
  • Requires Poetry
