I AM NOT RESPONSIBLE FOR ANY DAMAGES!!! ;)

Please please read this guide carefully (from beginning to end), and over and over again before you first start!! This guide is for advanced users!! If you are a newbie then I will try to "tone" it down a bit :). But it is your Kuleana for making sure that you understand and do everything correctly! The installation part is only going to be for Windows as I am running Windows.

------------------------------------------------

Heimdall can run on:

Microsoft Windows (XP and up)

Mac OS X

Linux (Debian)

32 bit and 64 bit

------------------------------------------------

Prerequisites:

Microsoft Visual 2010 C++ Redistributable (Note! Only for Windows users.)

32 bit - http://www.microsoft.com/downloads/en/details.aspx?familyid=A7B7A05E-6DE6-4D3A-A423-37BF0912DB84

64 bit - http://www.microsoft.com/downloads/en/details.aspx?FamilyID=BD512D9E-43C8-4655-81BF-9350143D5867

WinRAR (or your preferred extracting software. Note must be able to unpack .tar files.) - http://www.win-rar.com/

Downloading and Installing Heimdall (http://www.glassechidna.com.au/products/heimdall/)

Step 1

Download the appropriate Heimdall for your system, please make sure you only download Heimdall Frontend or Suite (Windows, Mac only) as will we only be working with that.

WINDOWS INSTALLATION FROM THIS POINT ON!

Step 2 (refer to Capture1 Photo)

Unzip the .zip file. Now navigate to the location/folder. Make sure you remember where the location is because this is where you’re going to be running Heimdall.

Step 3 (Installing the drivers)

Open up the “Drivers” folder and there should be a program called “zadig”. What this program will do is that it will replace the Samsung USB Composite Device driver (Download mode driver) with a generic driver called WinUSB (libusb 1.0).

Note: This will only replace the driver on one usb port (Port-by-Port basics)! For example if I have three usb ports, the one usb port that you are replacing the driver will only work with heimdall(download mode only) and the other two will continue work with OdinOneClick/Odin3 only.

(Refer to Capture2 Photo)

1.	Reboot your phone into download mode

2.	Run zadig as administrator, then connect your phone

3.	On the menu bar (Device,Options,Help) Click Options --> List All Devices

4.	Under USB Device select “Samsung USB Composite Device”

5.	Okie Dokie you can now click Install Driver

Note: If you get a popup about not being able to verify the publisher, just click install anyways. The drive installation may take a while.

6.	Once zadig finishes installing you can close it and disconnect your phone. Just do a battery pull, and restart normally

If my driver installation instructions are confusing or hard to understand lol just read the “readme” file.

WINDOWS INSTALLATION DONE! :)

Preparing a ROM for use with Heimdall (For an example I will be using JF6 stock)

Step 1 - Downloading the rom and extracting the rom if it is in a compressed form (.rar file, etc).

Go to http://www.samfirmware.com/WEBPROTECT-i897.htm . Please register (its free!! :) ) or login. Under Firmware, download “I897UCJF6” (or whichever version you want). Using WinRar (or your preferred software) extract the .rar file. When it asks for a password, it’s underneath the last file, “I897UCJH7” on the website (in dark black color! Highlight it so you can see it :) ).

Note: OdinOneClick brings the Captivate back to Stock JF6

Step 2 – Extracting the .tar/.md5 file

After extracting the .rar file, it will provide you with a .tar file. Now normally for Odin3 users all we would do is pop that straight into the PDA section and hit start. But that’s not what we’re going to do today lol. Now using WinRar (or again your preferred extracter) extract the UCJF6 .tar file

Step 3 – Just a FYI step ;) (refer to Capture4 Photo)

After extracting the .tar, it will now provide you with multiple files. Now most of these files should look familiar or sound familiar, if not than omg you should not be playing around with these files! Okie Dokie we are now done for this section :rolleyes:

Note: Notice that there is no boot.bin (Primary Bootloader), or sbl.bin (Secondary Bootloader). If you need 2.1/2.2 bootloaders because you flashed Gingerbread bootloaders, I will post them at the end :).

Using Heimdall(I will be flashing stock JF6 as an example)

If you downloaded the Suites package there is two heimdall’s. One is the frontend which uses a user interface, and the other is command line based. I prefer to use frontend because that includes a GUI (user interface) to work with. If you know how to use command line then feel fine to use that instead, but note again that this guide is only for frontend.

Step 1

Run/Execute “heimdall-frontend”

Step 2

When Heimdall opens there will be different slots to put files. Now use your common sense ;) and browse for the files that you extracted out of the .tar files.

Example:

Under FactoryFS click browse and find the FactoryFS.rfs file that you extracted out of the .tar file from the section before. Now finish up the rest ;)! When you’re finish double check that the correct files are in the correct place!! Make sure that you do not checkmark repartition device!

Note: Please be ultra-careful when flashing with bootloaders!! Do not flash only one bootloader, always flash two at a time!!

Step 3 (refer to Capture3 Photo)

Check again that all the necessary files are in the right place and necessary checkboxes are checked. When you’re finish reboot your phone into download mode and connect it to the usb port that you reinstalled the drivers to (Windows and Mac only). Wait for about 5 secs. (to let your OS know you plugged in something) then click Start. Wait for Heimdall to complete uploading everything and yay!! You should get a “flash completed successfully”! Then your phone will now restart.

Note: If you need to do a Master Clear wait for the phone to completely boot up and then type in the phone dialer *2767*3855#. The internal SD card will completely be reformatted (Please remove your external SD card if you have one).

And there we have it! A phone flashed back to stock using Heimdall. You can use this guide if you wanna flash a different rom after :).Make sure you read all of the threads in the first section(especially Mac users!!!) before starting. Again always be carefully with flashing with bootloaders!! Another thing to be careful with is the repartition device checkbox:

(From original thread.Post#764 Page#77)

Now after reading that please make sure that when you repartition, to include both bootloaders when you flash!! (unless someone can confirm that our Captivate does backup the bootloaders)

Please send me a PM if anything is incorrect, and I will be glad to change anything :)! If you have any questions, post below or in the original thread!
