Phone rebooting it self when charging ?
tips : Charging your LG Optimus 2x from AC socket via original LG AC-USB adapter may cause the loop of rebooting. This is because the charger is letting in too much voltage. To avoid this charge your phone by plugging it into USB port of your PC / laptop or replace original charger with another one.

You would need:
ROM Manager (Get it from Market)
Clockworkmod Recovery (Install from ROM Manager)
Smartflash for P990 (Windows only)
HK Stock ROM
Super One Click Root

Optional Install:
Stock ROM Performance Patch
AOSP style lockscreen
Silent Screen Capture
Batter Percentage Mod
New System Font
You can find more on XDA

1. Download and install Super One Click on your computer.
2. Enable USB Debugging at Applications>Development>USB Debugging
3. After that plug in your usb and leave your phone there.
4. Now open Super One Click on your computer.
5. Click 'ROOT'
6. Let the process run, after it's done.

Then Rooting is completed
Now you just download the latest HK Stock ROM (v10D) from the Firmware thread.
[Because they've updated it so you don't need to flash to v10a then flash to v10d, save a lot of time ]
If you just got your phone, it means nothing else installed,
you go to market to download the ROM Manager.
Install it, click the first item in the menu : 'Flash Clockworkmod Recovery'
It will prompt you for SuperUser Access and you grant it.
After flashing complete it will show the version of your CWM Rocovery.

1. After flashing CWM you get ready your firmware you just downloaded.
2. Plug in USB and enable Mass Storage.
3. Put it inside your EXTERNAL SD card (Not INTERNAL)
4. After it's done, turn off your phone.
5. Turn it on while pressing power button + volume down button until the 'ANDROID' word shows.
*Hands off and scroll through the menu with volume up/down button.
*Power button is like 'enter' in CWM.
6. Scroll down and choose 'wipe data/factory reset'.
7. Optional Step (?) Choose 'advanced' and choose 'wipe dalvid cache'
8. After wiping it you choose 'install zip from sdcard'
9. Then choose 'choose zip from sdcard'
10. Choose the firmware zip and confirm.
11. Wait it flash and reboot the system.

See whether you get a bootloop or success
