A Python CLI tool for downgrading i(Pad)OS devices.
## Usage ``` Usage: deleo [OPTIONS] IPSW LATEST_IPSW A Python CLI tool for downgrading i(Pad)OS devices. Options: --ecid INTEGER -v, --verbose --version Show the version and exit. -t, --shsh-blob FILENAME SHSH blob for target restore. [required] -u, --update Keep user data during restore (not recommended if downgrading). -o, --ota-manifest FILENAME OTA build manifest for latest IPSW. --help Show this message and exit. ``` ## Requirements - Python 3.8 or higher - Valid SHSH blobs - A Linux or macOS system - Windows support will be coming in the future - `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 here. - 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 here. - 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 here, 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](https://pypi.org/project/deleo/): - ```python3 -m pip install deleo``` - Local installation: - `./install.sh` - Requires [Poetry](https://python-poetry.org) ## Support For any questions/issues you have, [open an issue](https://github.com/m1stadev/deleo/issues).
