iPod Classic Modding Guide

Table of Contents

Introduction

This guide collects insights into modding the iPod Classic (5th, 6th, and 7th generation). I originally created it to collate the information I gathered during my own iPod modding journey. Think of this as a helpful starting point: it's not a complete, step-by-step manual, but it offers valuable resources and should help you get started with confidence.

Necessary equipment

A basic list of items to gain access to your iPod's internals. Equipment needed for specifc mods will be listed in their respective sections.

Identify your iPod model

Information gathered from various sources¹² around the web. Select the model that matches your iPod, or answer the questions to identify it if you're not sure.

iPod Identifier

Does your iPod have a metal faceplate?

Yes

No

Thanks to ConiShadow in the iPod Discord server for supplying the graphics!

Opening your iPod

It's relatively simple to open an iPod. However, people notoriously struggle³ to open the 6th/7th generation models due to the metal front and back. If you know what you're doing, you should be able to get at the internals within a few minutes.

The iPod has 11 clips holding the front and back together. You'll need to disengage these clips with your pry tool (iSesamo or alternative) to access the internals.

YouTuber Geek Detour has created a reference card⁴ that you can print out to identify where the internal clips are.

Storage mod

Storage mods are quite simple to perform. However, you must consider:

• Which generation iPod you have
• Which other mods you're looking to implement

The answers to these questions will steer your choices when determining your storage adaptor.

Device storage limits

There are a few different limitations on the maximum storage capacity of iPods⁵ running the stock operating system.

A database of your iPod's files is loaded into RAM. A 32MB RAM iPod has a limit of around 20,000 items (songs, videos, etc.), whilst the 64MB RAM models have a limit of around 50,000. If you're not sure how much RAM your device has, use the iPod identifier.

You should also be aware that some generations (specifically 6/6.5) have a hard storage limit. However, you can flash newer firmware to bypass this.

Check out the compatibility table below for more details.

Storage adaptor options

There are a number of adaptors of varying prices and configurations. The table below outlines the most common choices with pros and cons. The adaptors are in preference order.⁷ Higher is better.

Battery Mod

WIP

Storage mod compatibility

Not all batteries are the same. Due to the variance in their dimensions (width, height, depth), you may find yourself trying to install a battery that doesn't fit into your device.

thick backplate iPods have the extra depth to accommodate all battery & storage combinations.

thin backplate iPods have less space, and therefore choice is more limited.

This table should help guide you on which battery to choose.⁹

Identifying battery dimensions

Batteries should have a 6-digit code printed on their front which can be used to identify their dimensions. For example, the code 785239 can be broken down to 78mm width, 52mm height, 3.9mm depth.

Bluetooth Mod

This mod is much more complicated than the battery or storage mods, and will require soldering wires to parts of your iPod's circuit board.

There are a few routes that you can take when implementing a Bluetooth mod.

Oxyll's "elegant Bluetooth" mod

IcyEgg-9339's "Right Way" mod

Parts Plus Pods Bluetooth mod

Parts Plus Pods is a channel dedicated to fixing broken iPods. The channel has multiple videos demonstrating how to implement Bluetooth. If you would prefer not to do this mod yourself, their store also sells "kits" at a reasonable price which have Bluetooth and an upgraded battery.

Software Mod

WIP

Bypassing 6th generation storage limits

Reddit user Olsro¹² has produced a guide on how to flash newer firmware versions onto your device. This means you'll be able to increase the storage on your device up to 2TB.⁵

Rockbox

WIP

Is Rockbox right for me?¹³

If you have ever thought the following:

• I want to drag and drop music, no iTunes!
• I want to theme the UI!
• I want games and emulators!
• I want to play FLACs!

Rockbox is for you.

If you have ever thought the following:

• I'm ok with iTunes!
• I want less hassle with getting album art to show up!
• I want smooth animations of the stock UI!
• I don’t want bloat in my firmware!

iPodOS is for you.

Installing games

Reddit user Olsro¹² (again!) has started a project to preserve iPod games. Follow the guide there to install (almost) all of the original iPod games on your device.

Debugging

Force restart¹⁴

1. Put the Hold switch firmly in the unlocked position.
2. Press and hold the Menu and Select (Centre) buttons for 8 seconds, or until you see the Apple logo.

DFU Mode¹⁵

1. Connect the device to a computer using a USB cable.
2. Hold down both the Select (Centre) and Menu button.
3. The device will reboot. Keep holding both buttons.
4. After 8 seconds, release both buttons.

Disk mode¹⁶

1. Set your iPod on a flat surface and make sure your iPod has a battery charge.
2. Slide the Hold switch on and off.
3. Perform a force restart.
4. Press and hold the Select (Centre) and Play/Pause buttons until you see the disk mode screen. Make sure you press the Play/Pause buttons towards the outside of the click wheel and not near the centre.
5. Connect your iPod to your computer. The screen on your iPod should display Do not disconnect. Make sure you eject your iPod in iTunes before you disconnect it from your computer.

Debug mode¹⁷

1. Perform a force restart.
2. Immediately after the Apple logo appears, hold down the Previous Track and Select (Centre) buttons.
3. The screen should display the Apple logo. Once the screen turns white, it is safe to release the two buttons.

FAQ

My screen shows a circled red X and a support link, what's happened?

This usually means a hard drive failure.¹⁸ You can confirm this by putting the iPod into debug mode and checking the hard drive status. Possible issues:

1. The hard drive is not connected properly.
2. The connector is damaged.
3. The hard drive is damaged or has failed.

Can I put an 6th/7th gen faceplate on my 5th generation iPod?

Yes. However, you'll also need to transplant 6th/7th gen parts:

• The midframe.
• (optional) The clickwheel plastic. You can skip this, but if you do, the clickwheel won't sit flush with the faceplate.¹⁹²⁰²¹ This video guide should help you understand how to do this. As you can see, the centre of the plastic wheel has a slightly increased depth.

I've added music to my iPod, and now it's slow/crashes when I turn it on

You're probably nearing or have reached the maximum number of songs your iPod can handle. 32MB RAM models are limited to around 20,000 songs, whilst 64MB RAM models are limited to around 50,000. Identify your iPod model to understand your device's limits.

I've tried to check my SMART data and I see "Error"

This is likely a faulty hard drive. If the device is modded, check that ribbon connections are seated correctly. If it's not modded, you will need to replace the drive. Check Storage mod for more information.

I've checked my SMART data because my iPod is behaving strangely. What is "bad"?

The Wikipedia entry for S.M.A.R.T tells us everything that we need to know.

Reallocs will have an upper threshold before total drive failure. We don't know what this value is for an iPod hard drive, but if the number you see isn't 0, it is significantly more likely to fail. If you're noticing issues and see a high count, it may be easier to replace the drive. Check out Storage mod for more information.

My clickwheel centre button isn't working

The foam pad behind the clickwheel can shift out of alignment, preventing the button from clicking in correctly.

You'll need to disassemble your iPod and recentre (or replace) the foam pad²². As you can see in the image below, there is a black foam pad over each button. Ensure that these are centred.
