//USE HEIMDALL TO FLASH THE BOOTLOADERS
//WARNING: BRICKS REPORTED FROM ODIN3 1.3 USERS !!
Since Richthofen didn't update his Odin3 solution to use the LATEST bootloaders (03.dec.2010), there you have it.
If Samsung Drivers are properly installed for Download Mode, the flashing process is just as safe to do so with Odin3 as with Heimdall.
When the Galaxy S is connected to the PC in Download Mode, you have to see in Device Manager: USB Composite Device Samsung and Samsung Mobile Modem.
If you see this, is 100% safe to use Odin v1.3 or v1.7 to flash the bootloaders.
Preparations: Make sure you have the drivers installed (i.e Kies is recognizing the phone) and "USB Debugging" is turned on in "Settings -> Applications -> Development" menu. Type *#0228# in the dialer and check Voltage value (without USB plugged in) is atleast 3800(mV).
HEIMDALL METHOD:
01. Unplug the phone from the computer (if connected)
02. Kill all Kies related software (tray agent, etc)
03. Start Heimdall Downloader
04. Plug in the phone to the computer
05. Download adbDownload.zip
06. Unpack adbDownload.zip and run/double click on Download.bat
07. Download RAZ_P-SBL_SGS.tar
08. Unpack RAZ_P-SBL_SGS.tar
09. Move to Heimdall (GUI) and select boot.bin and SBL.bin.
10. Flash the bootloaders
ODIN3 METHOD:
1. Unplug the phone from the computer (if connected)

4. Plug in the phone to the computer
5. Download adbDownload.zip
6. Unpack adbDownload.zip and run/double click on Download.bat
