heimdall(1) tool for flashing firmware on Samsung Galaxy S devices heimdall(1)
Heimdall (c) 2010-2017 Benjamin Dobell, Glass Echidna


This software attempts to flash your Galaxy S device. The very nature of
flashing is dangerous. As with all flashing software, Heimdall has the
potential to damage (brick) your device if not used carefully. If you're
concerned, don't use this software. Flashing ROMs onto your phone may also
void your warranty. Benjamin Dobell and Glass Echidna are not responsible
for the result of your actions.
These instructions are for Linux operating systems.

Flashing Heimdall Firmware Package with Heimdall Frontend:

As of Heimdall Frontend 1.3 there are now two main ways to flash a ROM from
Heimdall Frontend. The simpler and preferred option is to download a
Heimdall Firmware Package and follow the following steps.
1. Fully charge your device (use the wall charger as it's faster).
2. Open the a terminal and run Heimdall Frontend by typing:

From the "Load Package" tab, under the "Heimdall Firmware Package" section click the "Browse" button.
Use the dialogue that appears to navigate to, and select, the Heimdall firmware package that you wish to flash.
You will see progress bars appear as the package is decompressed and extracted.

When the package has finished being decompressed you should see information about the particular firmware package that has been selected.

Verify that your device is listed under "Supported Devices". If it's not then STOP immediately! DO NOT flash this firmware to your device! Instead search for an appropriate firmware package for your device.

If you believe there is a mistake and your device is actually supported please get in contact with the firmware developer (not Glass Echidna!) and ask them to rectify the issue. If the developer provided a URL you may be able to contact them by pressing the "Homepage" button.

If you've verified your device is supported you may continue to press the "Load / Customise" button.
You should now be looking at the "Flash" tab. If not verify that you did in fact push the "Load / Customise" button.

Generally, you won't NEED or WANT to customise a firmware package! In which case you can safely move on to step 9.

Nonetheless, the "Flash" tab provides you with a means to customise the firmware package before flashing it to your device. See "Performing a Custom Flash with Heimdall Frontend" for more details.

Put your Galaxy S device into download mode and plug it in to your PC.

Download mode can be accessed several different ways depending on your
particular device model. If you're unsure how to do this please search
online for the appropriate method.
Press the "Start" button.
Heimdall Frontend will display the progress and inform you when the flash is complete.

If something went wrong i.e. your device wasn't detected because it wasn't in download mode, then the status section will let you know the cause of the problem.

Performing a Custom Flash with Heimdall Frontend:

This is the advanced means of flashing firmware to your device.
If you're not an advanced user or a developer, in the event that a Heimdall
Firmware Package doesn't exist for the particular firmware (or files) that
you wish to flash, then I strongly recommend you get in touch with the
developer of the firmware (or files) and politely ask them to create a
Heimdall Firmware Package for you. In doing so, you avoid the risk of
making mistakes due to inexperience.
If you're looking to customise an existing Heimdall Firmware Package then
follow steps 1-8 of "Flashing Heimdall Firmware Package with Heimdall
Frontend" then start from below with step 5.
1. Fully charge your device (use the wall charger as it's faster).
2. Download a decrypted device ROM or a Heimdall Firmware Package
and extract everything to the one directory.
3. If the ROM is not a Heimdall Firmware Package it may instead be provided
as multiple archives (nested or otherwise), extract them all to the same
NOTE: If you want to use the CSC then extract it last. If you're asked
to overwrite files then do so.
3. Open the a terminal and run Heimdall Frontend by typing:

Select the "Flash" tab. From the "Flash" tab you're able to completely customise a flash.
Before you can chose which partitions you want to flash with particular files you MUST first select a PIT file. To do this click the "Browse" button in the "PIT" section. This will open a dialogue allowing you to navigate to and select a valid PIT (.pit) file.

If you do not already have a valid PIT file stored on your computer you can download your device's PIT file from the "Utilities" tab.

If a valid PIT file has been selected then the "Add" button below the "Partitions (Files)" list-box will be enabled. Press this button to add a partition to your flash.
When you first add a partition you will see the "Partition Name" and "Partition ID" be populated with information. Use the "Partition Name" drop down to select which partition you wish to flash. "Partition ID" will automatically update and is never directly editable.
You must then select a file to flash to the partition that you just specified using the "Browse" button under the "File / Partition". You will not be able to flash, create a firmware package or add another partition until you have selected a file. However, you're still able to press the "Remove" button if you've decided not to flash the partition you've just specified.
When you've specified a file name then you'll be able to see the updated information in the partition list to the right. You can select any partition from this list and customise it as you see fit.

You can also remove a partition from the list by selecting it and clicking the "Remove" button. Removing a partition from the list doesn't remove it from your device, it simply means it will not be flashed.

Repeat steps 7-9 as often as needed to specify all the partitions/files that you wish to flash.
Now you can chose whether you would like to repartition your device as well as whether you would like to prevent the device rebooting once a flash has been completed. These options can be enabled or disabled by toggling the "Repartition" and "No Reboot" check-boxes.

In the general case you will only need to enable repartition if you wish to change the PIT file on your device. Keep in mind that repartitioning will wipe your device!

The "No Reboot" option is rarely required. It's mostly in place so you can manually boot straight into recovery mode after a flash (rather than booting up normally).

If you've added at least one partition to your flash (and selected a file for that partition) then the "Start" button will be enabled. Press the "Start" button to begin the flashing process.

You may notice that the "Create Package" tab becomes available at the whenever the "Start" button becomes available. From this tab you're able to create a reusable, redistributable Heimdall Firmware Package with the files and partitions you just selected. See "How to Create a Heimdall Firmware Package" for details.

Heimdall Frontend will display the progress and inform you when the flash is complete.

If something went wrong i.e. your device wasn't detected because it wasn't in download mode, then the status section will let you know the cause of the problem.

Flashing Firmware from Command Line:
Fully charge your phone (use the wall charger as it's faster).
Download a decrypted device ROM or a Heimdall Firmware Package and extract everything to the one directory.
If the ROM is not a Heimdall Firmware Package it may instead be provided as multiple archives (nested or otherwise), extract them all to the same location.

NOTE: If you want to use the CSC then extract it last.

Put your Galaxy S device into download mode and plug it in..
Open a terminal and navigate to the directory where you extracted the ROM/firmware files.
Type the following to list all the functionality Heimdall supports:

heimdall help
Before flashing, you must first know the names of the partitions you wish to flash. These can be obtained by executing:

heimdall print-pit --no-reboot
The inclusion of --no-reboot ensures the phone will not reboot after PIT file has been downloaded and displayed. After executing a command with the --no-reboot argument, the next command should include the --resume argument.

NOTE: You can still safely reboot your phone manually (with the power button) after executing --no-reboot commands.

Use the help and print-pit output to construct a command with all the files you want to flash.

Here is an example that does a full flash and repartition on a GT-I9000:

heimdall flash --repartition --resume --pit s1_odin_20100512.pit --FACTORYFS factoryfs.rfs --CACHE cache.rfs --DBDATA dbdata.rfs --IBL+PBL boot.bin --SBL Sbl.bin --PARAM param.lfs --KERNEL zImage --MODEM modem.bin
Heimdall will display the progress as it flashes so that you know things are working as they should.

How to Create a Heimdall Firmware Package:

Firstly, Heimdall's firmware package format is just a regular TAR archive
compressed with gzip. The only two real requirements are that a valid
firmware.xml must be included (refer to Appendix A) and you can only
include files (no directories, links etc.) As such if you'd like there is
nothing preventing you from creating Heimdall packages manually. Of course
Heimdall Frontend provides a simple user interface that takes care of all
the hard work for you.
There are two ways in which you can create a firmware package. You can
create a package from scratch, or you can load an existing package, apply
modifications and then save the package. Creating a package from scratch
is the preferred approach, by taking this approach you're far less likely
to run into file name length limitations.
Before you can access Heimdall Frontend's firmware creation functionality
(available from the "Create Package" tab) you must first specify which
files will be included in your package, as well as a few flashing options
i.e. Whether or not users should repartition when flashing. This
information must be filled out from the "Flash" tab in exactly the same
fashion you would provide information to flash your device (see "Performing
a Custom Flash with Heimdall Frontend"). As mentioned above, it's not the
preferred means, but you're able to load an existing package as a starting
point for this information.
Once you've specified the files/partitions you wish to include in your
firmware package the "Create Package" tab will become available. Clicking
this tab will display additional information that you can include in your
package. In order to continue you must fill out all sections except for the
URLs section, which is optional. The following is a break-down of what all
these options mean.
- General Firmware Information: -

Firmware Name - This is the name of your particular firmware. An
example would be "Cyanogenmod".
Firmware Version - This is the version identifier for your package. Any
valid string will be accepted, although the inclusion of decimal
point version number is preferred i.e. "7.1". If it makes sense
then feel free to append a text string like "RC1" or "Beta 1" to
the decimal point version.
Platform Name - This is the name of platform (or operating system) that
your firmware is based on. In most cases this will simply be
Platform Version - This is the operating system version that your
firmware is based on. Again decimal point version numbers are
preferred over text, i.e. "2.3.4" is preferred over "Gingerbread".
Developers -

URLs (Optional):

Homepage - Here you can enter your personal URL or a URL particularly
pertaining to the firmware being packaged. The URL must be well
formed for it to work. An example of a well formed URL is
"". It is
important to include "http://" in order to specify the protocol as
other protocols such as "ftp://" are equally valid although
unlikely to be used.
Donate - Here you can enter a URL that will link users to a page to
make donations for the effort you've put into developing your
firmware. Once again the URL must be well formed but there is no
requirement on how your donation page should work. For instance
both "" and
"" are
equally valid.
Developer Info:

Name - Here you can enter in the name of individual team members or a
team name. Click "Add" and the developer will be added to the list
on the right. If you make a mistake you can select a developer from
the list and click "Remove". You can list as many developers as you
like, however visual constraints of the "Load Package" tab means
only a few names will be visible. Where possible you may want to
opt for team names over listing individual team members.
Supported Devices -

This section allows you to create a list of devices that are supported by your particular firmware. Although Heimdall isn't capable of enforcing this we strongly recommend you take this section seriously. If filled out correctly you could help save a number of accidental bricks!

Device Info:

Manufacturer - This is where you can enter the name of the manufacturer
for a particular device. For now this will most likely be
Name - This is the human readable name for a particular device.
"Galaxy S", "Galaxy S II", "Droid Charge", "Vibrant" and
"Galaxy S (Telstra)" are all valid names. There are a lot of
possible variations here so be as specific as you think is
Product Code - This is by far the most important bit of device
information. Device names tend to be region specific and further
subject to the whims of telecommunication companies and resellers.
Product Codes (or product IDs) are designated by manufacturers and
are generally the definitive means of referring to a particular
device. Examples are "GT-I9000", "GT-I9100" and "SCH-I897". If
you're unsure of a particular product code then both Google and
GSMArena are your friends!
After filling out all the necessary information the "Build" button will be enabled. If it's still disabled then you know you're missing some required information. In particular you must specify at least one developer and at least one supported device. Pressing the "Build" button will bring up a save dialogue where you must chose a file name for your particular package. Don't worry about specifying the ".tar.gz" extension Heimdall Frontend will take care of this automatically.

Once you've chosen a file name Heimdall Frontend will begin the process of building the firmware package. In doing so a valid firmware.xml file will be generated from the information entered. All files will be archived in a single TAR file then the TAR archive will be compressed via gzip compression. Compression will take a little while but you will see progress bars so you know the application hasn't hung. When the progress bars disappear you're finished making your package.

Congratulations! You're now ready to redistribute your firmware package online or by any means you see fit.

Appendix A - firmware.xml

The following details a part of the Heimdall Firmware Package format. This is only relevant to developers or advanced users who wish to create Heimdall Firmware Packages outside of Heimdall Frontend or in some way integrate support for the format in their own software.

All Heimdall Firmware Packages must contain a file called firmware.xml. This file stores flash information and meta-data for the package as well as information about other files contained within the package.
The format is fairly straight-forward so it won't be explained in great detail. Nonetheless the following is an example of a valid firmware.xml file.

<?xml version="1.0" encoding="UTF-8"?> <firmware version="1"> <name>Test Firmware</name> <version>1.1</version> <platform> <name>Android</name> <version>2.3.4</version> </platform> <developers> <name>Benjamin Dobell</name> <name>Hedonism Bot</name> </developers> <url></url> <donateurl></donateurl> <devices> <device> <manufacturer>Samsung</manufacturer> <product>GT-I9000</product> <name>Galaxy S</name> </device> <device> <manufacturer>Samsung</manufacturer> <product>GT-I9000T</product> <name>Galaxy S (Telstra)</name> </device> <device> <manufacturer>Samsung</manufacturer> <product>GT-I9000M</product> <name>Vibrant</name> </device> </devices> <pit>Nl3276-I9000 s1_odin_20100512.pit</pit> <repartition>0</repartition> <noreboot>0</noreboot> <files> <file> <id>0</id> <filename>gq3276-boot.bin</filename> </file> <file> <id>24</id> <filename>Uh3276-cache.rfs</filename> </file> <file> <id>22</id> <filename>em3276-factoryfs.rfs</filename> </file> <file> <id>11</id> <filename>fl3276-modem.bin</filename> </file> <file> <id>21</id> <filename>Xd3276-param.lfs</filename> </file> <file> <id>3</id> <filename>if3276-Sbl.bin</filename> </file> <file> <id>6</id> <filename>cr3276-zImage</filename> </file> </files> </firmware>

New lines need not be included and the order in which elements are specified does not need to match that of the above example.

One and only one <firmware> element must be included. The <firmware> element must also have a version attribute specified. The version must be parsable as an integer and indicates what version of the Heimdall Firmware Package specification the package adheres to.

All data is stored as strings, however a <file>'s <id> element must be parsable as an integer. The <id> value represents the partition ID (according to the specified PIT file) that the file should be flashed to.

A <firmware>'s <repartition> and <noreboot> elements must also be parsable as an integer. However, as they represent boolean values, a value of zero ("0") means false (or disabled) where as a non-zero value (typically "1") means true (or enabled).

File names are specified relative to the TAR archive in which firmware.xml and all other files are to be stored. Heimdall Firmware Packages do not support directories or links, as such file names should only be a name and not a path.

<url> and <donateurl> are the only optional elements, all other elements must be included.
