Although this device was officially released as the Galaxy S 4G, it is sometimes referred to as:

  • the Vibrant 4G, or
  • the Vibrant Plus

This is because T-Mobile previously released a phone in the Samsung Galaxy S lineup, referred to as the Samsung Vibrant.


At the Samsung Galaxy S 4G sub-forum on XDA-Developers, you will find a large source of guides, ROMs, mods, and themes for this phone.


Before doing anything for this phone make sure you have the correct drivers installed.

SIM Unlocking

SIM unlocking a device allows a phone to use the SIM cards from other carriers. This is also known as carrier unlocking.

You can follow the guide found here to do so, but you must be rooted.


Well, what exactly is it?

It is what allows you to make changes to your Android system, as well as enable you to use features that are otherwise locked away. Also, beware. A phone in the rooted state has a voided warranty.

OK, so how do you actually root the SGS4G?

There are a few different ways of gaining root access on the sgs4g.

  • Root your phone with SuperOneClick.
  • Root your phone with SuperOneClick (with ZergRush) - verified by bhundven here.
  • Install a kernel that installs the su binary to /system/xbin/su. Any of the CWM Voodoo Lagfix kernels will do this.


  1. Download the latest SuperOneClick.
  2. Unzip the packaged files through a program like WinRAR, Winzip, or 7-Zip.
  3. Put your SGS4G into USB debugging mode. To do so, navigate to “Settings” –> “Applications” –> “Development” and check the "USB debugging" mode to ON.
  4. Connect the phone to the computer via USB cable.
  5. In the folder of the file you unzipped, run the SuperOneClick.exe file.
  6. Click "Root" and wait for the process to finish.
  7. When prompted to test if the root worked, you can choose to skip.
  8. Install busybox as recommended.
  9. Donate if you wish.

Note: If it did not work, please reboot your computer and phone, then try again.

Download Mode

How to get into download mode:

  1. Take your microUSB cable and plug it into the computer, but not the phone (yet).
  2. Take out the battery from the phone.
  3. Put the battery back into the phone.
  4. Put the back cover back onto the phone, make sure it's snug so the battery doesn't fall out.
  5. Hold vol + and -, keep holding them.
  6. Plug the USB cable into the phone.
  7. You should now be in download mode and should see a picture of a yellow triangle with Andy and a shovel in the middle.
  8. You can now flash your Odin/Heimdall file.

If this method does not work, you can try some of the other methods here.

Installing a ROM

There are a variety of custom ROMs from Froyo to Gingerbread that commonly provide speed enhancements, remove bloatware applications, or provide features that the stock ROMs lack. Warning: Do NOT use ROM Manager on this phone. It does not work and will brick your SGS4G.

Note: To flash from a Froyo (2.2.x) ROM to a Gingerbread (2.3.x) ROM, please use the Gingerbread ext4 Starter Pack guide.


General Odin install procedures are listed below:

  1. Ensure you have the proper drivers installed for this phone.
  2. Download Odin3 v1.85.
  3. Download the files from the author's post.
  4. Unzip the files using an unzip tool.
  5. Put your phone into download mode.
  6. Connect phone to computer via USB cable. You will see Odin confirm you have plugged in a device.
  7. Follow the instructions of the author of the ROM to place files in their correct location on Odin.
  8. Click Start.
  9. If the author of the thread says to do anything after, follow those instructions. If not, you can unplug the phone and reboot.

Clockwork Mod

General CWM installation procedures:

  1. Ensure you have Clockwork Mod Recovery on your phone. DO NOT USE ROM MANAGER TO GET IT.
  2. Download the .zip file and place it onto the root of your SD card.
  3. Power off the phone.
  4. Get into recovery by holding Volume Up + Volume Down + Power until you see the SGS4G splash screen.
    • To navigate in recovery, use the volume up and down buttons to move around, and the power button to select.
  5. See is the instructions have special conditions such as wiping data/cache and remounting.
    • To remount to, for example, UMMU, navigate to "mounts and storage" and set the values to "unmount /cache", "mount /data", "mount /sdcard", and "unmount /system"
  6. Select "install zip from sdcard" --> "choose zip from sdcard"
  7. Select the file you downloaded from the thread.
  8. Go back and navigate to "reboot system now"


A guide for those who are without Windows OS or prefer the reliability of Heimdall.
