Finally there is some great news for Samsung Galaxy S i900 owners looking for an easy and pain less root. Senior Member, TGA_Gunnman, at XDA Forums has released a one click rooting tool for Samsung Galaxy S which not only roots Android 2.1 Eclair and Android 2.2 Froyo, but also gives you a one click unroot option.

Here is the step by step guide on rooting and unrooting Samsung Galaxy S with a single click:

If you are planning to use this guide on Windows X86 or X64 then make sure to download Samsung drivers before embarking on the root process. This rooting application requires Dot Net Framework Version 4 to work.

  • The first step is to enable USB debugging mode on your device. You can enable USB debugging on your phone by going to Menu > Settings > Applications > Development and check mark USB Debugging.
  • Now download Galaxy S i9000 one click root file, extract the contents and save them on your desktop [or wherever your prefer].
  • Now connect your phone to the computer and double click on Galaxy S I9000 One-Click Root file.
  • Now simply click One-Click Root 2.1 or 2.2 on the screen and follow the onscreen command mode instructions to complete the root process. Please note that for One-click root 2.1, your phone needs to be running Android 2.2 2.1 Eclair and for One-click Root 2.2, Android 2.2 Froyo.
  • In case you are using this application to unroot your phone then simply follow the instructions above and click on One-click Unroot.

Disclaimer: Please attempt this guide at your own risk. AddictiveTips won’t be responsible in case your device bricks or any other damage occurs due to this method.

Update: Now you can also one-click root/unroot Samsung Galaxy S with Mac OS. The detailed guide is posted here.

    No Signature verification failure!

    For FROYO

    First enable USB debugging mode and remove the external SD Card.

    follow instructions here to root galaxy s i9000, see video :

    http://forum.xda-developers.com/showthread.php?t=803682

    after this the device is rooted , reboot your device.

    Download RyanZA’s OCLF 2.0 in the app market , open it and

    click EXT2 and after that One Click Lag Fix 2.2+

    All DONE!!

    Galaxy S GT-I 9000 2.2. USB debug mode enabled. The phone doesn’t reboot and doesn’t go into recovery mode. This rooting program doesn’t work at all here. Calling the rootme2.2.bat directly works, but there is no command “reinstall packages”, only “apply sdcard:update.zip”. WTF?

  • karx11erx

    Updating using sdcard:update.zip results in a signature verification error.

  • Dennis

    hello

    i have the same problem with the ” reinstall package”. cant find it.
    I have checked the usb debugging. And i dont have a sd card.
    ive tested the “apply sdcard:updatet” , and its says installation failed.
    I have froyo 2,2.

    / Dennis, Sweden

    if someone can solve or help me with this pls email me a kryddan84@hotmail.com

  • Ghettosp

    please i will sincerely like to know how long this process takes cos i tried the z4root which is also one click root and after 3 hrs my phone hanged and i had to put it off ND STILL IT WASN’T ROOTED I THANKGOD THAT NOTHING HAPPENED 2 MY GALAXY S

    • http://www.hqraja.com/ Haroon Q. Raja

      This method does work and we have tried it out ourselves on our Galaxy S I9000. And it definitely does not take hours. Though like any rooting procedure, try it entirely at your own risk because one never knows what can possibly wrong.
