I am disappointed no one has answered the issue about the "error:device not found" question other than saying to use z4root. Is this because it's an error that can't be solved and no one wants to admit there's no solution? If z4root is the solution to rooting the Optimus T then I think this post needs to be killed so more people aren't wasting their time.

For those who learn visually, iamlilysdad has put together an awesome walkthrough video of this process which you can find
What You'll Need:
- Sun JRE,
- The Android SDK, . Install this on the root of your computer so the path is C:/android
- Drivers for the LG phone installed on your computer. Instructions can be FOUND HERE courtesy of our favorite android hacker, modder, developer, blogger (jack of all trades) gbhil
- And the file I have attached to this post. Download it, unzip it, and put the 3 files inside in your android-sdk-windows\tools folder created from installing the SDK.
/\You need to have installed/done all of the stuff in the "what you'll need" section. From this point on I'll assume you've done that./\
Ready?:
Step 1: Plug your phone into your PC with the USB cable.
Step 2: Make sure the phone is charge only (don't mount as USB drive) and USB debugging is enabled. Menu > Settings > Applications > Development > check mark USB debugging
Step 3: Launch the SDK manager, should be something like C:/Android-sdk-windows SDK Manager
Step 4: Open a CMD window and type the following:
cd c:\wherever-your-sdk-tools-folder-is (mine for example is C:\android\tools however in the new SDK the correct directory would be "Platform Tools", and not just "tools". See what you have on your directory)
adb push rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage
adb push su /data/local/tmp/
adb push busybox /data/local/tmp/
adb shell
chmod 4755 /data/local/tmp/rageagainstthecage
chmod 4755 /data/local/tmp/busybox
cd /data/local/tmp
./rageagainstthecage (let things sit a couple minutes (2), your phone will disconnect from the computer and you'll be removed from your ADB session)
adb shell This should return a "#" symbol instead of a "$" symbol. If it does you're good. If not go back and start from the beginning of step 4
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /data/local/tmp
./busybox cp su /system/bin
./busybox cp busybox /system/bin
cd /system/bin
chmod 4755 su
chmod 4755 busybox
busybox --install /system/bin
exit
exit
If you get to this step "busybox --install /system/bin" you get an error, do this:
4-A) Download superuser (free) from chainsDD in the market (this is step 5 below)
4-B) Download titanium backup (free) in the market
4-C) Launch titanium. You should get a request to give it root permissions select always allow. Now in titanium, hit the "problems" button and let it install busybox
4-D) Reboot phone and enjoy
Some phones are having a problem on that step while others are not.
Step 5: Go to the android market on your phone and download "Superuser"(free). The developer will be listed as ChainsDD.

What I ask is, if this helps you root, please watch this thread and help someone who may be experiencing issue. Yes, I am asking you to donate your time. The same donation I made while writing this so you could root your phone
Thanks:
gbhil - as always thanks, you rock rainman lol.
- Without your exploit many phones would not be rooted today.

Thanks for taking the time to do this.
Personally, I'm having a bit of a problem getting the "#" to show up.
I've completed the required steps multiple times to no avail.
After I get the "$" and it disconnects, then re-connects, I attempt the cmd "adb shell", and I get "error: device not found"
Thanks ahead of time!Last edited by Douglife; 06-18-2011 at 12:13 AM.
