Those of you that need to flash back to the Samsung Vibrant stock ROM can do so with the following directions.  This works on phones that are updated to Froyo and need to be flashed back to gain root access as well as those who have bricked their Vibrant by messing around.

You will need drivers installed on the computer that you use to flash your Samsung Vibrant back to the stock rom.
You can get these drivers here: 32-bit Driver | 64-bit Driver

Instructions to flash Vibrant back to Stock:

  1. Get your phone into Download mode by holding volume down and power.
  2. Download Odin for Flashing (Download Link)
  3. Open Odin
  4. Extract and Load the 512.pit file (Download Link)
  5. Extract and Load the Vibrant JFD Image (Download Link)
  6. Don’t check anything else, “Auto Reboot” and “Reset Time” should be checked by default
  7. Connect your phone to the Computer via USB
  8. Hit “start”! be patient!

If you don’t see a progress bar after hitting start (after a minute) start over at step one.

Having Trouble with Download Mode:
If you are stuck on the PC and phone screen just hold both volume buttons and power at the same time. let the Vibrants screen come on and go back off and on the second time before the Vibrant comes back on let go of the power button while still holding the volume buttons. This should get you back to download mode.

Most Android users are somewhat tech savy otherwise you’d just get an iPhone right?  So you’ve bought a Samsung Galaxy, Captivate, or Vibrant and want to run free tethering apps and cool file managers but have no idea how to root your phone to allow you to run these applications.  Well here it is.

That said you may want to experiment with your Samsung Galaxy S or some of its variants like the Captivate or Vibrant and get root access on your phone.

Un-Rooting Instructions

If something goes wrong or you need to return your phone for some reason you can always un-root. The instructions are the same, except that in this case you press the “Unroot” button. It is suggested that you restore the phone back to stock ROM before even needing to unroot.

The process above has been tested on Samsung Galaxy S phones with Android 2.1 Éclair. The following versions of the device should work as well: GT-I9000 (the original Galaxy S), Captivate SHG-I897, Vibrant SGH-959, GT-I9000M and Epic SPH-D700 (untested but should work just fine).

Rooting adds few files to your system and unrooting removes them:
