FACTORY RESTORE
[WARN]THIS IS FOR THE SGS-T959 VIBRANT
ONLY.
Do not use this on any other phone (such as the Galaxy S 4G) unless you have the SPECIFIC replacement files for your device.[/WARN]
[WARN]DO NOT use this if you have updated to the Galaxy S GINGERBREAD bootloaders. This file contains ONLY an sbl.bin and will HARD brick your phone if you have replaced the bootloaders. [/WARN]
[INFO]1. Download the zip folder from
here.
2. Unzip the contents, and save them somewhere easy to find.
3. Open the Odin3 1.7 .exe file.
4. Click PDA. Navigate to the .tar file, and click open.
5. Remove battery, SIM, and micro SD from phone.
6. Re-insert the Battery. Boot into download mode by holding both Volume buttons and plugging in the USB. If you get a screen that says "downloading: do not turn off target" with a digging android, you're in download mode.
7. Your phone should show up in ODIN (the box will turn yellow w/ letters and numbers).
8. Your screen should now look like this. If it doesn't, unplug your phone, and do it again.
[NOTE]IGNORE THE .PIT FILE. ALSO, THE .TAR FILE WILL HAVE A DIFFERENT NAME. Yes, I did steal most of this guide from my Captivate thread

[/NOTE]
9. If everything looks good, the hit start.
DO NOT UNPLUG IT. When it finishes, Odin will say PASS in green. You can then unplug, and your phone will reboot.[/INFO]
