When i try to use the adb shell it says "error: no device found

check to see if you have debug mode on your cell.. as well as check to see if you have ADB Interface in your device manager when your cell is connected to your computer.

i tried rooting with this guide..

C:\Documents and Settings\quit_hatin>cd C:\Documents and Settings\quit_hatin\My
Documents\OptimuskRootZVD

C:\Documents and Settings\quit_hatin\My Documents\OptimuskRootZVD>adb shell
$

Rooting the LG Optimus S with software version LS670ZVD


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 will work no matter how you updated to LS670ZVD. Therefore KP500 is NOT needed whatsoever!

WARNING: If you screw up on ANY of these instructions, you will have to reboot your phone and try again starting from step 1!!!

NO LONGER RELEVANT: 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.
Techneek TV (mrinehart93) has a great video tutorial on how to do this in Windows Vista/7. Watch it here.

The su, busybox and gingerbreak binaries as well as the Superuser app are included in OptimusRootZVD.zip, which is attached to this post. The ADB binary can also be found in this file (you won't need ADB in the Windows PATH variable). Thanks DroidXcon!
Make sure you extract the files to an easily accessible folder.

Much kudos to Sebastian for releasing this exploit.

Special thanks to Nick7, Zefie, Beezy, KSmithInNY, and everyone else who tries so hard to free this awesome device from the hands of LG. You guys rock.


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 OptimusRootZVD.zip
3) Prepare the /data/local/tmp directory with write permissions (THIS IS REQUIRED!)4) Push the required files to the /data/local/tmp directory5) Fire up the shell
6) Change to the /data/local/tmp directory
7) Set correct permissions. REQUIRED: If you don't do this you will be slapped.
8) Run gingerbreak (this can take a while, so please be patient. If it gets stuck for more than a few minutes, reboot your phone and try again from step 1. This will automatically give you a root shell if successful.)
If that doesn't work, you can try
9) Mount the /system partition read-write
10) Change to the /data/local/tmp directory
11) Copy su and busybox to /system/bin
12) Set correct permissions on su and busybox
13) Exit the shell
14) You're done! You may now reboot and have fun with your rooted Optimus!
If you followed all of the instructions correctly, Superuser has already been installed.



CUSTOM RECOVERY

Now that your phone is rooted, you may now install the Xionia CWMA recovery kernel.

You may elect to use drellisdee's Custom Recovery, but it will cause issues if you have a device with the new LCD display (which means use Xionia CWMA unless you're feeling adventurous AND know exactly what you're doing).


NANDROID BACKUP

Now that your phone is rooted and has a custom recovery kernel, you need to make a nandroid backup. Boot your phone into recovery mode by firing up a Windows command prompt and issue the following command:Your phone will reboot to recovery mode. Once it fully boots to recovery mode, navigate to "backup and restore", then "backup" and your phone will make a nandroid backup for use when you screw something up by being a NOOB.

I get down to step 11 and type, cat su > /system/bin/su
cannot create /system/bin/su: read-only file system
Did I do something wrong?

Ok I followed the steps and everything works but do I have to install the Kernel provided or can I just run stock?

So this will work even after the android 2.3 update is pushed?

 

[sblood86]

So this will work even after the android 2.3 update is pushed?

That's unconfirmed but very unlikely, any software change almost certainly requires a different rooting method.

Best bet is to either wait for a rooting method that has tested to be posted before accepting the OTA update.

Or wait for a 2.3 rom to be posted which will already have root.

 

[DroidXcon]

Hey drew why dont we throw the Shell script in here to make it easier for those who choose to go this route with rooting to make the final steps easier?

 

[noobuser1992]

one question if i upgrade my phone to 2.3 from 2.2.2 will i have to reroot my phone?

Look back one page

EDIT: That was in reply to whether the rooting method will work, but it applies in this instance as well.

reboot your phone, go to adb shell, then type su (watch your phone-and allow when super user pops up) then you have to install a custom recovery(see signature), from there, pick the rom you want to install and follow the directions in the guide

Hey drew why dont we throw the Shell script in here to make it easier for those who choose to go this route with rooting to make the final steps easier?

I will, just not yet. Still working on a few small issues before that awesomeness gets released. It involves a modified gingerbreak so just wanna make sure I get this right before unleashing the beast.
