Ramrod

ramrod is an iOS command line utility that is involved in firmware update and restore procedure of iOS devices at least since iOS 6.

There is not much known about its functionality or usage except that it is mentioned in ~/Library/Logs/iPhone Updater Logs (on OSX) or [Username folder]\Application Data\Apple Computer\iTunes\iPhone Updater Logs (on Windows) in case of some unsuccessful restores / updates.

ramrod is contained in the ramdisk in H6SURamDisk.dmg (which is in /usr/standalone/update/ramdisk/ folder on 7.0.4 iPhone5s) and there in /usr/libexec/ramrod/. You just have to get rid of the 1st 0x1b (27) bytes to make the dmg readable.
