This article is about the firmware itself. If you are trying to get a copy of the firmware files, please see Dumping firmware and Extracting firmware. NOTE: Please excuse the chaotic layout of this article. It is under construction. :-)
This is the main firmware image of the iPod. This part has been encrypted ever since the iPod Nano 2G.
Here is a comparison between the different aupd partitions of firmware version in the iPod Nano 2G:
This is the resource filesystem of the iPod firmware. It is unencrypted and of not much use to this project.
The Nano 4g doesn't have the aupd partition. Instead, seven new partitions were added. We assume that these have the following functions, the question mark means that we are not completely sure:
- appl - bootlogo?
- bdhw - bad hardware?
- bdsw - bad software?
- chrg - sleep, but charging?
- diag - diag mode
- disk - disk mode
- lbat - low battery logo?
