Heimdall is a cross-platform open-source tool suite used to flash firmware (aka ROMs) onto Samsung mobile devices. The "Heimdall Suite" is composed by: Heimdall command line Heimdall Frontend. Heimdall command line package includes: Heimdall command line tool and udev rules (for non-root USB access). Heimdall Frontend package includes: Heimdall Frontend - graphical UI only. So, this script comes with an option (GUI) that can be set at build time. The default is GUI=yes, but if you don't want to install the frontend, you could do that by setting GUI to 'no' in command line: GUI=no ./heimdall.SlackBuild Don't forget to reloaded udev after installing this package /etc/rc.d/rc.udev reload ------------------------------------------------------------------------------ DISCLAIMER: This software attempts to flash your Galaxy S device. The very nature of flashing is dangerous. As with all flashing software, Heimdall has the potential to damage (brick) your phone if not used carefully. If you're concerned, don't use this software.
