Design: Apple seems to use the same GUI design from the production firmware to the factory one.

Release and NonUI "restore bundles" have the same packaging structure (bootloaders, kernel, restore ramdisk, update ramdisk and root filesystem), but can also include other files such as debug and development variants of each respective component.

Restore bundles are like contents of IPSW files which can be restored on devices using internal restore software such as PurpleRestore or AirSwitch. Unlike regular iOS Firmwares, NonUI ones are distributed in "restore bundles".

  • Most internal applications require the use of SkankKit (replacement for UIKit in NonUI firmwares) to produce special layers such as text on the framebuffer.
  • It has some additional Private Frameworks in /System/Library/PrivateFrameworks for internal GUI apps and command line utilities.
  • Boot loader passes arguments to kernel (unlike RELEASE boot loaders as of iOS 5.0) which makes it easy to disable AMFI.
  • SSH daemon is pre-installed as dropbear, can be connected to over usb.
  • /usr and subfolders contain many UNIX command line utilities.
  • No SpringBoard, requires the use of daemons to launch SwitchBoard.app as a multi-app launcher instead.
  • /AppleInternal folder, which the hierarchy inside get priority over hierarchy in /.
  • Skankwerk (gear) logo image file in /Firmware/all_flash/all_flash.factoryfa/.
  • DEBUG fused baseband firmware in /Firmware/.
  • DEVELOPMENT dyld_shared_cache in /System/Library/Caches/.
  • DEVELOPMENT fused kernelcache with more symbols (located in /System/Library/Caches/ on the filesystem), and with individual kexts in /System/Library/Extensions.
  • FACTORY fused SEP firmware in /Firmware/all_flash/all_flash.factory/.
  • DEVELOPMENT fused bootloaders in /Firmware/dfu/ and /Firmware/all_flash/all_flash.factory/.
  • Unlike production iOS firmwares, NonUI ones have the following differences: The SpringBoard replacement, named SwitchBoard, allows the launching of a GUI for some of those applications. They are known as "NonUI (No User Interface)" builds, because most applications are command line ones and the UI is different to that of a regular device.
