Heimdall is an Open-Source utility to work with Android devices manufactured by Samsung. It allows to flash firmware components into memory via FastBoot/ODIN+USB. I have created a patch to build this nice tool on FreeBSD OS (QT gui works as well, to build it you need qt-{gui,qmake,uic,moc,rcc,…} packages installed). When patch is included into the project sources and release is done, I will prepare a FreeBSD port for this nice utility which is only missing a memory dump and live boot to be totally perfect :-)
