This is the wiki for the freemyipod project. Freemyipod is a project aimed at reverse-engineering non-iOS iPods (all models other than the Touch) and creating tools and documentation so that other people can port alternative firmwares to them such as Rockbox or Linux. Freemyipod is a relaunch of Linux4nano.

FAQ

I'm not an embedded software developer, what can I do with my iPod?

• If you have an iPod nano (2nd generation), iPod classic (6th generation) or an older iPod, you can install Rockbox.
• If you have an iPod nano (6th generation) or iPod nano (7th generation), you can install a theme.
• If you have an iPod nano (7th generation), you can install NanoApps.
• If you have another model, there's nothing you can currently do to help us add support and/or speed up the process, since it requires a lot of time and effort. Keep an eye on our wiki and social media for any updates!

I'm an embedded software developer, what can I do with my iPod?

• There's a U-Boot port, and Linux boots with an initramfs on iPod nano (2nd generation), iPod nano (3rd generation), iPod nano (5th generation) and iPod nano (7th generation)
• wInd3x allows untethered and safe code execution (no permanent modification) on iPod nano (3rd generation), iPod nano (4th generation), iPod nano (5th generation), iPod nano (6th generation) and iPod nano (7th generation)
• Rockbox bootloader has been published for iPod nano (3rd generation) and iPod nano (4th generation), but the Rockbox port is not yet completed.
• Tethered code execution using S5Late (a vulnerability in DFU_DNLOAD packet parsing code) for iPod nano (6th generation), iPod nano (7th generation) and iPod shuffle (4th generation).
• Untethered code execution using ipod_sun (CVE-2010-1797) for iPod nano (6th generation) and iPod nano (7th generation).
• There's a set of earlier tooling (emCORE/emBIOS/iBugger) for iPod nano (2nd generation), iPod nano (3rd generation), iPod nano (4th generation) and iPod classic (6th generation) which was exploiting other vulnerabilities and was a lead-up to a port of Rockbox, but it's mostly abandoned.
