Bootrom
Boot Chain
VROM->LLB->iBoot->Kernel->System Software
One of the iPhoneLinux goals are to replace that Boot Chain after iBoot :
VROM->OpeniBoot->Linux Kernel->X Server->Window Manager
Upgrade Process
Restore mode
The common upgrade process chain is VROM->DFU->WTF->iBoot->Kernel->Ramdisk->Restore, also called restore mode.
DFU mode
See full article here. To flash an older version of the iPhone software you have to let your phone reside in DFU. In iTunes you have to press the Alt-Key (Mac) or the shift-key (Windows) when pressing 'Restore' to be able to manually chose an update file (ipsw file).
