IPSW (iPod1 SoftWare or iPhone SoftWare) Files have the Magic Number 504B0304 (PK\003\004) and thus are ZIP archives. They can be modified with typical zip/unzip tools (i.e. change extension to .zip and double click). IPSWs are used to deliver theApple TV/iPad/iPhone/iPod touch firmware to the end-user.
1IPSW files have been used since the very first iPod, though they have a different format than iOS-based devices.
IPSW Contents
- Restore Ramdisk
- Update Ramdisk (Some firmwares don't contain this because of various reasons- Error 3002 means you are trying to update with an IPSW that is missing this)
- Filesystem Ramdisk (the largest .dmg file)
- Device Tree
- kernelcache.release.XXXXXXX file (application processor specific i.e S5L8900, S5L8920, S5L8720, S5L8922, S5L8930, S5L8940)
- BuildManifest.plist (first appeared in firmware 3.0?)
- Restore.plist file
- Firmware\
- all_flash\
- \dfu (Folder)
- iBEC.XXXXX.DFU (hardware specific i.e. M68ap, N82ap, etc.)
- iBSS.XXXXX.DFU (hardware specific i.e. M68ap, N82ap, etc.)
- WTF.XXXXX.DFU (hardware specific i.e. M68ap, N82ap, N45ap, N72ap - currently not present in firmwares for the iPhone 3GS and later, because it is mostly used to patch issues with the DFU mode that was burned into the bootrom)
- ICE3_XX.XX.XX_BOOT_02.06.Release.bbfw (Contains the baseband and the bootloader. X stands for a number. This is the baseband version. 02.06 is the bootloader. Only in the iPhone 4 firmware.)
Example
This is a ls -alR of an extracted iPhone 3GS 3.0 Firmware IPSW.
