Rooting the LG Optimus S with software version LS670ZVC
If you have the new software version LS670ZVD, this
guide won't work! Please see this post!
For those wanting to take the shortcut: http://forum.androidcentral.com/lg-...optimus-s-control-center-1-0-016-updated.html
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.
READ THIS FIRST!!! If you accepted the OTA update (didn't use the LGMobile update tool), this guide will not work as-is. You will first need to force-flash the previous version of the software (V9), then update to VC using an alternative method. Instructions for doing this can be found here. If your phone came with ZVC (or ZVD), this also applies to you!
OWNERS OF OPTIMUS S DEVICES WHO CAN'T UPDATE WITH THE LG UPDATE TOOL:
WARNING!!!! If you previously reverted to the stock ROM and DIDN'T restore the stock recovery (meaning you still have custom recovery), this guide will not work as-is. If you are running VC and you have either drellisdee's Custom Recovery or Xionia CWMA, all you need to do is flash FlashRootVD-signed.zip which can be found at the bottom of the LS670ZVD rooting guide.
Custom Recovery Notice: With this new software version (and root method) you CAN install drellisdee's Custom Recovery. The instructions can be found here and do not need to be changed, though I will recommend Custom Recovery 1.2 which can be found here.
Alternate Custom Recovery: You may also elect to use Zefie's Xionia Clockwork Recovery. Like drellisdee's recovery, Xionia Clockwork is a fantastic custom recovery. Both are highly recommended, the choice is up to you. Again, the instructions do not need to be changed.
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 rageagainstthecage-arm5.bin binaries are included in OptimusRoot.zip, which is attached to this post.
Make sure you extract the files to an easily accessible folder.
The V8_to_V9 update zip can be found here.
This file must be placed on the root of your sdcard PRIOR to doing anything outlined in this guide.
Many thanks go to Zefie's hard work, more directly this post for providing the rooting method.
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.
Finally, super special thanks to cordell, DCJoe, KingDavidBaker, KSmithInNY and sfhub for putting their phones at risk to solve the OTA update hurdle. You guys also rock. If there is anyone I missed, let me know and I'll add you to the list.
Now, on to the guide.
1) Fire up a terminal (cmd.exe on Windows)
2) Change to the directory where you extracted the files from OptimusRoot
THIS STEP IS NOT OPTIONAL!!! This will produce an expected error message and is used to trigger the mounting of the /system partition.
5) Push the required files to the sdcard (NOT /data/local/tmp, that will fail)
12) Mount the /system partition read-write
If you don't install Superuser and ask why you can't get root access, you will be slapped. Hard.
If you have the new software version LS670ZVD, this
guide won't work! Please see this post!

Now, on to the guide.
1) Fire up a terminal (cmd.exe on Windows)
2) Change to the directory where you extracted the files from OptimusRoot
3) Reboot in LG's recovery mode
4) Using the Volume-Up and Volume-Down keys, select the option labeled "apply sdcard:update.zip" and press the Menu key.
THIS STEP IS NOT OPTIONAL!!! This will produce an expected error message and is used to trigger the mounting of the /system partition.
5) Push the required files to the sdcard (NOT /data/local/tmp, that will fail)
6) Fire up the shell
7) Change to the sdcard directory
8) OPTIONAL: Some users have reported this step as necessary. Your mileage may vary, though it probably doesn't hurt to do it anyway.
9) Run rageagainstthecage (this will disconnect and reconnect your device twice, let it sit for a minute to make sure)
If that doesn't work, you can try
10) Fire up the shell (again)
11) You should have a "#" instead of "$". If you still have "$" try this guide again, starting from step 1.
12) Mount the /system partition read-write
13) Change to the sdcard directory
14) Copy su and busybox to /system/bin
15) Set correct permissions on su and busybox
16) Exit the shell
17) You're done! You may now reboot, install SuperUser from the Market (author: ChainsDD) and have fun with your rooted Optimus!
If you don't install Superuser and ask why you can't get root access, you will be slapped. Hard.
