Here is a really brief tutorial, how you can get any Optimus 2x rooted via your computer and the SuperOneClick program:
PLEASE, READ THE WHOLE #1 POST, BECAUSE IT HAS SEVERAL GUIDES, SO YOU SHOULD TRY EVERYTHING BEFORE ASKING! DON'T SPAM THE THREAD IF POSSIBLE!
1. Install the USB driver needed to have ADB access to the phone, you can download it from here:
UPDATED: April 4th, 2011
or if the link above doesn't work:
2. Connect your phone, enable USB debugging (Settings->Applications->Development)
3. Run SuperOneClick
4. Choose root!
5. Run the test in the end...and you will have it, you got root access on your 2.2.1 LG Optimus 2X device!
+1 I recommend you first uninstalling the Car Home app and F-Secure (if you are not using it) because it is highly responsible for freezes and instabilites (AFAIK).
If the tutorial above fails, here is djmcnz's method:
Use the psneuter option, I had the same problem with rage, psneuter worked instantly.
Optimus 2x, Unbranded, Android 2.2.2 (out of the box, no OTA)
All I did was:
Install LG driver (first post)
Open SuperOneClick 1.7
Check Superuser app
No reboots or shell root required.
Su is permanent, withstands a reboot.
IF YOU GET DRIVER NOT SIGNED OR OTHER ISSUES AT STEP 1, here is something that could help you:
One more guide, this may help you too (credit goes to Maliacrete):
For all those who get stuck at "waiting for device" with the SuperOneClick try running it as an Administrator (right click, Run as Administrator) or follow these:
a) make sure your phone is "seen" from your pc under hardware (http://www.junefabrics.com/android/driver.php). Follow the instructions here. If needed install your drivers from the link on the bottom of the junefabrics page.
b) Download the PdaNet from here (http://junefabrics.com/android/download.php), when prompt to replace the drivers, press NO.
c) if at this point the PdaNet istallation tells you that it cannot detect any phone you need to go back to the drivers problem. No correct drivers (debugging), No root.
d) Run the SuperOneClick and it will surely do the job.

Wireless penetration testing on handhelds (still need more time):
-Nokia n810 - probably capable via p54-spi driver
-HTC Kaiser - via newer kernels and wl12xx
HTC Kaiser (KAIS130)
Kaiser-Buntu (Ubuntu on the Kaiser) - own porting [EXPERIMENTAL]
