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. :-)
Contents
osos
This is the main firmware partition of the iPod. This part has been encrypted ever since the iPod Nano 2G.
aupd
Here is a comparison between the different aupd partitions of firmware version in the iPod Nano 2G:
rsrc
This is the filesystem of the iPod. It is unencrypted and of not much use to this project.
Nano 4g
The Nano 4g doesn't have the aupd partition. Instead, nine 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?
- osos - apple firmware
- rsrc - firmware resource filesystem (integrated games etc.), unencrypted fat16 filesystem
