How To: Root Samsung Galaxy S, Captivate and Vibrant

Unlock Galax S

It is said that savvy smartphone owners like to experiment with their devices. Hence, even today many of the iPhone users keep jailbreaking their devices to unlock the hidden potential of Apple’s handset.

That said you may want to experiment with your Samsung Galaxy S or some of its variants like the Captivate or Vibrant and “root your way” to full access. Thus far this process was complicated and only the select few dared to do it. However, with the new GUI it’s pretty simple and anyone can do it. Here’s how:

PC Instructions

  1. Download the rooting application from here (here’s the mirror link).
  2. dotNet Framework version 4 – you can grab it from Microsoft’s website.
  3. Install Samsung Drivers – download link.
  4. Extract the contents of GalaxyS_Vibrant_One-Click_Root.rar to a folder.
  5. Connect your phone in the USB Debug mode (MENU -> Settings -> Applications -> Development -> USB debugging = Checked )
  6. Launch the file “T-Mobile Vibrant One-Click Root.exe” file.
  7. Click the “One-Click Root” button.

You can watch the video for the full procedure on The Unlockr.

Mac Instructions

  1. First of all, it is required that your Mac runs OS X 10.5 or higher
  2. Download the rooting application from here (mirror link).
  3. Connect your phone in the USB Debug mode (MENU -> Settings -> Applications -> Development -> USB debugging = Checked)
  4. Click on the “Root me” button.
  5. After the phone has rebooted into recovery select “apply sdcard:update.zip” and choose “Reinstall Packages” for the US models using the volume keys and then press the home button for I9000 and I9000M, and the power button on the right top side for US models to start the process.

And that’s it!

Un-Rooting Instructions

If something, God forbids, goes wrong you can always un-root. The instructions are the same, except that in this case you press “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:

  • /system/xbin/busybox (version 1.17.1)
  • /system/xbin/su
  • /system/app/Superuser.apk (version 2.3.1)
  • and links /system/bin/su to /system/xbin/su

WARNING: Although nothing bad should happen, you should acknowledge that neither IntoMobile nor its affiliates can be responsible for your phone and/or eventual loss of information. Moreover, you should know that rooting the phone can void your warranty.

  • Esot3ricD3sign

    so yea, i have the tmobile galaxy s 4g.  i tried this and i got the e signature verification failed. so i decided to use superoneclick and it worked with no problems. so everyone who has this e signature problem just use super one click instead. 

  • Sandyr1952

    i have the captivate and need to root it.  Have not been able to find an easy way to do this.  Please help by posting EASY directions, much appreciated!!

  • Jay kishan

    Works like a charm!! Kudos to the Author.. keep up the good work :)

  • Michiel Verkaik

    No luck, I tried the MAC instructions with a Galaxy S SGH-T959 (T-Mobile), firmware 2.1-update1, build ECLAIR.UVKA2.  The phone does reboot, but in step 5 in recovery mode, I don’t get that option (apply sdcard:update.zip).  I only see “reboot system now”, “reinstall packages”, “delete all user data” and “delete cache data”

    • John

      Same for me :( it sucks

    • Paramedicschwarz

      Same for me on Froyo. No choice shown to Update fro SD.

  • Marianne

    My phone doesn’t even get into a “recovery” mode. My phone is running the official 2.2 version for Canada. Help?

  • Versadesigns

    I always hear about rooting, but I have yet been daring enough too. I know they are coming out with Google Talk, and I heard the only way I can get it is on 2.3. I have Froyo 2.2 and don’t want to buy a new phone, but want the update.  (can you give me courage)

  • Janettyang

    should i have my SD card in while i do this? i’m afraid it’ll erase all my files…

  • Jim

    I have a galaxy S vibrant and used SuperOneClick to [root] it in less than five minutes.

  • Hmshop

    above did not work for my Samsung Galaxy S 4G. Got same signature verification error but Super One Click 2.1.1 had no issue rooting my cell in less than 5min :D

  • Juan

     did not work for my Samsung Galaxy S 4G. Got same signature verification error. The red writing said it could not find the file. It appears that the exe one click file never moved the zip to my sd card, So I got a file not found, then the program aborted. Good news nothing got messed up and I was able to reboot successfully. I forgot to mention it never auto booted from the start. I did that manually and also got into recovery mode manually 

  • Deadflesh69

  • Pattymelt420

  • Mickey45cook

    It looks like everyone is having the same problem with the file “apply sdcard:update.zip” not appearing Dusan but I don’t see anyone replying with any answers or ideas.  Shouldn’t someone be moderating this page?  I wish someone had some answers because with the silence along with it not working, I’m feel like I may have just downloaded a trojan virus on my iMac.  I’m getting no file named “apply sdcard:update.zip”, and when I hit reinstall packages it says “signature verification failed.”  Any ideas at all??

  • Rmay4975

    was going to try this but I see alot of people having the same issue. Guess I will wait a little long. Way to give support guys! Fail.

  • Vttimwhite

    Was just about ready to do this, but too many negative comments and unanswered questions.

  • SGS

    Signature verification failed.. Does anyone has any solution?

  • http://profiles.google.com/funnycomputergeek ANdrew ORr

    BEWARE

    This only works for Captivates running Android 2.1

    Once you upgrade from 2.1 to 2.2 Samsung automatically un-roots your phone

    2.2 can’t be rooted using this method, as the phone now won’t use these unsigned files

  • Steven

    Followed everything exactly as outlined. Did not work. I am running Windows 7 Pro. Samsung Captivate is Captivate SHG-I897. I wonder what I did wrong…

  • Ms Angelabarnes

    hi i tried rooting Samsung Galaxy S using the software and it didn’t root it.  when i connected the usb and clicked on “Root Me”, apply sdcard:update.zip did not appear as an option.

  • Dan Paller

    can this work with my samsung galaxy s 4g running 2.3.6 

    • M_keys7

      Yes it can.  Using SuperOne Click v 2.3.3.0  as rooting program.  Once SuperOne Click is opened go to Exploit (next to donate button) and select  zergRush then Root and your done

  • Dan Paller

    i have a mac, and it works up until i have to use the update.zip file!! after that it says something about a verification failed… so please help!!

  • justin

  • Murph-44-

    Why is it when i plug my phone in(Vibrant) it only says usb connected only and no usb debugging connected???

    • M_keys7

      debug can be found by settings>applications>development>usb debugging

    Clicking the link to download the rooting application led to the megaupload website, which has been seized by the FBI.

    Can’t do anything until the APP is downloaded from a reliable source.

  • green

  • Anthony

    gives me the same error E:signature verification failed
