The Rockbox manual (version 3.14) Samsung YH-920

Chapter 1. Introduction 12
1. Introduction
1.1. Welcome
This is the manual for Rockbox. Rockbox is an open source firmware replacement
for a growing number of digital audio players. Rockbox aims to be considerably more
functional and efficient than your device’s stock firmware while remaining easy to use
and customisable. Rockbox is written by users, for users. Not only is it free to use, it
is also released under the GNU General Public License (GPL), which means that it will
always remain free both to use and to change.
Rockbox has been in development since 2001, and receives new features, tweaks and
fixes each day to provide you with the best possible experience on your digital audio
player. A major goal of Rockbox is to be simple and easy to use, yet remain very
customisable and configurable. We believe that you should never need to go through a
series of menus for an action you perform frequently. We also believe that you should
be able to configure almost anything about Rockbox you could want, pertaining to
functionality. Another top priority of Rockbox is audio playback quality – Rockbox,
for most models, includes a wider range of sound settings than the device’s original
firmware. A lot of work has been put into making Rockbox sound the best it can, and
improvements are constantly being made. All models have access to a large number
of plugins, including many games, applications, and graphical “demos”. You can load
different configurations quickly for different purposes (e.g. a large font for in your car,
different sound settings for at home). Rockbox features a very wide range of languages,
and all supported models also have the ability to talk to you – menus can be voiced and
filenames spelled out or spoken.
1.2. Getting more help
This manual is intended to be a comprehensive introduction to the Rockbox firmware.
There is, however, more help available. The Rockbox website at http://www.rockbox.org/
contains very extensive documentation and guides written by members of the Rockbox
community and this should be your first port of call when looking for further help.
If you cannot find the information you are searching for on the Rockbox website there
are a number of support channels you should have a look at. You can try the Rockbox
forums located at http://forums.rockbox.org/. The mailing lists are another option, and
can be found at http://www.rockbox.org/mail/. From that page you can subscribe to
the lists and browse the archives. To search the list archives simply use the search field
that is located on the left side of the website. Furthermore, you can ask on IRC. The
The Rockbox manual (version 3.14) Samsung YH-920

Chapter 1. Introduction 13
main channel for Rockbox is #rockbox on irc://irc.freenode.net. Many helpful developers
and users are usually around. Just join and ask your question (don’t ask to ask!) – if
someone knows the answer you’ll usually get an answer pretty quickly. More information
including IRC logs can be found at http://www.rockbox.org/irc/. We also have a web
client so that you can join the Rockbox IRC channel without needing to install additional
software onto your computer.
If you think you have found a bug please make sure it actually is a bug and is still
present in the most recent version of Rockbox. You should try to confirm that by using
the above mentioned support channels first. After that you can submit that issue to our
tracker. Refer to section G(page 213) for details on how to use the tracker.
1.3. Naming conventions and marks
We have some conventions (especially for naming) that are intended to be consistent
throughout this manual.
Manufacturer and product names are formatted in accordance with the standard rules
of English grammar, e.g. “Samsung playback is currently unsupported”. Manufacturer
and model names are proper nouns, and thus are written beginning with a capital letter.
This manual has some parts that are marked with icons on the margin to help you
finding important parts or parts you could skip. The following icons are used:
Note: This indicates a note. A note starts always with the text “Note”. In order to b
make finding notes easier each one is accompanied by an icon in the margin as here.
Notes are used to mark useful information that may help you to get the most out of
Rockbox.
Warning: This is a warning. In contrast to notes mentioned above, a warning should !
be taken more seriously. Whereas ignoring notes will not cause any serious damage,
ignoring warnings could cause serious damage to your player. You really should read the
warnings, especially if you are new to Rockbox.
This icon marks a section that is intended especially for the blind and visually im- ¸
paired. As they cannot read the manual in the same way sighted people do we have
added some additional descriptions. If you are not blind or visually impaired you can
probably completely skip these blocks. To make this easier, there is an icon shown in
the margin on the right.
Links to the wiki are abbreviated by the name of the wiki page. Those names are still
linked so you can simply follow them like any other link in this manual. If you want to
access a wiki page manually go to Zhttp://www.rockbox.org/wiki/ and type the page
name in the “Go” box at the top of the page. Links to wiki pages are also indicated by
the symbol Zin front of the page name.

Chapter 2. Installation 14
2. Installation
Installing Rockbox is generally a quick and easy procedure. However before beginning
there are a few important things to know.
2.1. Before Starting
USB connection. To transfer Rockbox to your player you need to connect it to your
computer. For manual installation/uninstallation, or should autodetection fail
during automatic installation, you need to know where to access the player. On
Windows this means you need to know the drive letter associated with the player.
On Linux you need to know the mount point of your player. On Mac OS X you
need to know the volume name of your player.
The installation requires you to use UMS mode. In order to start up your YH-920
in UMS mode you need to:
1. Turn off the player (Original Firmware).
2. Connect your YH-920 to the computer using the data cable.
The player will now appear as a regular disk on your computer.
2.2. Installing Rockbox
There are two ways to install Rockbox: automated and manual. The automated way is
the preferred method of installing Rockbox for the majority of people. Rockbox Utility
is a graphical application that does almost everything for you. However, should you
encounter a problem, then the manual way is still available to you.
There are three separate components, two of which need to be installed in order to
run Rockbox:
The Samsung bootloader. The Samsung bootloader is the program that tells your
player how to load and start the original firmware. It is also responsible for any
emergency, recovery, or disk modes on your player. This bootloader is stored
in special flash memory in your Samsung and comes factory-installed. It is not
necessary to modify this in order to install Rockbox.
The Rockbox bootloader. The Rockbox bootloader is loaded from disk by the Samsung
bootloader. It is responsible for loading the Rockbox firmware and for providing
The Rockbox manual (version 3.14) Samsung YH-920

Chapter 2. Installation 15
the dual boot function. It directly replaces the Samsung firmware in the player’s
boot sequence.
The Rockbox firmware. Similar to the Samsung firmware, most of the Rockbox code is
contained in a “build” that resides on your player’s drive. This makes it easy to
update Rockbox. The build consists of a directory called .rockbox which contains
all of the Rockbox files, and is located in the root of your player’s drive.
Apart from the required parts there are some addons you might be interested in
installing.
Fonts. Rockbox can load custom fonts. The fonts are distributed as a separate package
and thus need to be installed separately. They are not required to run Rockbox
itself but a lot of themes require the fonts package to be installed.
Themes. The appearance of Rockbox can be customised by themes. Depending on your
taste you might want to install additional themes to change the look of Rockbox.
2.2.1. Automated Installation
To automatically install Rockbox, download the official installer and housekeeping tool
Rockbox Utility. It allows you to:
•Automatically install all needed components for using Rockbox (“Minimal Instal-
lation”).
•Automatically install all suggested components (“Complete Installation”).
•Selectively install optional components.
•Install additional fonts and themes.
•Install voice files and generate talk clips.
•Uninstall all components you installed using Rockbox Utility.
Prebuilt binaries for Windows, Linux and Mac OS X are available at the ZRockboxUtility
wiki page.
When first starting Rockbox Utility run “Autodetect”, found in the configuration
dialog (File →Configure). Autodetection can detect most player types. If autodetection
fails or is unable to detect the mountpoint, make sure to enter the correct values. The
mountpoint indicates the location of the player in your filesystem. On Windows, this is
the drive letter the player gets assigned, on other systems this is a path in the filesystem.

Choosing a Rockbox version
There are three different versions of Rockbox available from the Rockbox website: Re-
lease version, current build and archived daily build. You need to decide which one you
want to install and get the appropriate version for your player. If you select either “Min-
imal Installation” or “Complete Installation” from the “Quick Start” tab, then Rockbox
Utility will automatically install the release version of Rockbox. Using the “Installation”
tab will allow you to select which version you wish to install.
Release. The release version is the latest stable release, free of known critical bugs.
For a manual install, the current stable release of Rockbox is available at http:
//www.rockbox.org/download/.
Development Build. The development build is built at each change to the Rockbox
source code repository and represents the current state of Rockbox development.
This means that the build could contain bugs but most of the time is safe to use.
For a manual install, you can download the current build from http://build.rockbox.
org/.
Archived Build. In addition to the release version and the current build, there is also
an archive of daily builds available for download. These are built once a day from
the latest source code in the repository. For a manual install, you can download
archived builds from http://www.rockbox.org/daily.shtml.
Note: Because current and archived builds are development versions that change fre- b
quently, they may behave differently than described in this manual, or they may in-
troduce new (and potentially annoying) bugs. Unless you wish to try the latest and
greatest features at the price of possibly greater instability, or you wish to help with
development, you should stick with the release.
Please now go to section 2.2.3 (page 17) to complete the installation procedure.
2.2.2. Manual Installation
The manual installation method is still available to you, should you need or desire it by
following the instructions below. If you have used Rockbox Utility to install Rockbox,
then you do not need to follow the next section and can skip straight to section 2.2.3
(page 17)
Installing the firmware
1. Download your chosen version of Rockbox from the links in the previous section.
2. Connect your player to the computer via USB in MSC mode as described in the
manual that came with your player.

Chapter 2. Installation 17
3. Take the .zip file that you downloaded and use the “Extract all” command of
your unzip program to extract the files onto your player.
Note: The entire contents of the .zip file should be extracted directly to the root of b
your player’s drive. Do not try to create a separate directory on your player for the
Rockbox files! The .zip file already contains the internal structure that Rockbox needs.
If the contents of the .zip file are extracted correctly, you will have a directory called
.rockbox, which contains all the files needed by Rockbox, in the main directory of your
player’s drive.
Installing the bootloader
Installation
1. Download http://download.rockbox.org/bootloader/samsung/yh920/PP5020.mi4
2. Connect your YH-920 to the computer using UMS mode.
3. Rename the PP5020.mi4 file to OF.mi4 in the System directory on your YH-920.
Note: You should keep a safe backup of this file for use if you ever wish to switch b
back to the Samsung firmware.
Note: If you cannot see the System directory, you will need to make sure your b
operating system is configured to show hidden files and directories.
4. Copy the PP5020.mi4 file you downloaded to the System directory on your player.
2.2.3. Finishing the install
Safely eject / unmount the USB drive, unplug the cable and restart.
2.2.4. Enabling Speech Support (optional)
If you wish to use speech support you will also need a voice file. Voice files allow Rockbox
to speak the user interface to you. Rockbox Utility can install an English voice file, or
you can download it from http://www.rockbox.org/daily.shtml and unzip it to the root
of your player. Rockbox Utility can also aid you in the creation of voice files with
different voices or in other languages if you have a suitable speech engine installed on
your computer. Voice menus are enabled by default and will come into effect after a
reboot. See section 8.10 (page 78) for details on voice settings. Rockbox Utility can also
aid in the production of talk files, which allow Rockbox to speak file and folder names.

2.3. Running Rockbox
When you turn the unit on, Rockbox should load.
2.4. Updating Rockbox
Rockbox can be easily updated with Rockbox Utility. You can also update Rockbox
manually – download a Rockbox build as detailed above, and unzip the build to the root
directory of your player as in the manual installation stage. If your unzip program asks
you whether to overwrite files, choose the “Yes to all” option. The new build will be
installed over your current build.
The bootloader only changes rarely, and should not normally need to be updated.
Note: If you use Rockbox Utility be aware that it cannot detect manually installed b
components.
2.5. Uninstalling Rockbox
Note: The Rockbox bootloader allows you to choose between Rockbox and the original b
firmware. (See section 3.1.3 (page 21) for more information.)
2.5.1. Automatic Uninstallation
You can uninstall Rockbox automatically by using Rockbox Utility. If you installed
Rockbox manually you can still use Rockbox Utility for uninstallation but will not be
able to do this selectively.
2.5.2. Manual Uninstallation
If you would like to go back to using the original Samsung software, connect the player
to your computer, and delete the PP5020.mi4 file and rename OF.mi4 to PP5020.mi4
in the System directory on your YH-920. As in the installation, it may be necessary to
first put your device into UMS mode.
If you wish to clean up your disk, you may also wish to delete the .rockbox directory
and its contents. Turn the Samsung off. Turn the player back on and the original
Samsung software will load.
2.6. Troubleshooting
“File Not Found” If you receive a “File Not Found” from the bootloader, then the
bootloader cannot find the Rockbox firmware. This is usually a result of not

extracting the contents of the .zip file to the proper location, and should not
happen when Rockbox has been installed with Rockbox Utility.
To fix this, either install Rockbox with the Rockbox Utility which will take care
of this for you, or recheck the Manual Install section to see where the files need to
be located.

Throughout this manual, the buttons on the player are labelled according to the
picture above. Whenever a button name is prefixed by “Long”, a long press of approx-
imately one second should be performed on that button. The buttons are described in
detail in the following paragraph. Additional information for blind users is available on ¸
the Rockbox website at ZBlindFAQ.
Hold or lay the player so that the side with the controls and LCD is facing towards
you. Below the LCD is a four-way pad with the Down,Up,Left and Right buttons.
There are three buttons at the top of the right hand side of the player: Forward on
the top, Play in the middle and Rewind underneath. Below these buttons is the Rec
switch. Rockbox doesn’t take note of the actual position of the switch, but reacts to a
switching movement like pressing a regular button.
On the top panel of the player, from left to right, you can find the following: head-
phone/remote socket, line-in socket, internal microphone, and the Hold switch. Note
that when the Hold switch is moved towards the center of the player, hold is turned on
and all the other controls are disabled. Be sure Hold is off before trying to use your
player.
