Recovery Firmware

The following recovery firmware is downloaded by iTunes when a Samsung SoC-based iPod, iPhone (1st generation), or iPod touch (1st generation) is found in Recovery Mode. Each firmware contains a WTF and DFU image in 8900 format.

With some exceptions, the files are named in the format, where   is the device's WTF mode USB product identifier in hexadecimal. It is unclear where  comes from; in all cases it is , except with the iPod touch (1st generation), where it is. Build versions are those listed in the itunes.com/version file.

In later iOS devices, the WTF and DFU images are instead retrieved from the main IPSW for the latest firmware build.
