Rooting the LG Optimus S with software version LS670ZVD
If you are running the CM7 Gingerbread port:
You need to flash a VC-based version of nROM, ThundeROM or Lego ROM BEFORE using this guide.
Big Fat Disclaimer:
1) Make sure you read this guide in it's entirety before attempting root.
2) If you need clarification on any of the steps outlined in this guide, ask before experimenting!
3) As with all Android modifications/tweaks, there is ALWAYS a risk of bricking your device. Make sure you understand all of the steps in this guide before attempting to root your device.
4) Last but not least, I am not responsible for bricks due to your mistakes! You are performing these steps at your own risk.
This guide assumes you have added the Android SDK tools directory to your PATH variable. Instructions for Windows 2000/XP can be found here. Instructions for Windows Vista/7 can be found here. With the latest version of the Android SDK, the default tools folder is "platform-tools" which is in the "Android\android-sdk-windows" folder in Program Files. With some versions of the Android SDK the default tools folder is simply "tools" which is in the "Android\android-sdk-windows" folder in Program Files. Your mileage may vary.
The su, busybox and Superuser.apk binaries are included in OptimusRootVD.zip, which is attached to this post.
Make sure you extract the files to an easily accessible folder.
Special thanks to Nick7, Zefie, Beezy, and everyone else who tries so hard to free this awesome device from the hands of LG. You guys rock.
