You can follow step by step here.

I've simplified the instructions from many sources together into one compilation below, credits were duly honored to the original writers in the source section below.

Things to Do Before Proceeding
1. Battery is full.
2. Have the *.apk files of your favorite apps on PC if possible. Less hassle to find and install back afterwards.
3. I will not be held responsible should anything undesirable happen to your phone.

Firmware & Rooting
##Downgrading firmware##
1. Download v10a here.
2. Download and extract LG KDZ Updater.
3. Install msxml.msi, and load DZ_FW_UPD.exe.[isit copy the installer in phone sd card and install in phone?]
4. Set the option to 3GQCT and DIAG.
5. Load the firmware downloaded earlier, and launch the update. The phone will display EMERGENCY MODE! sign, but it's supposed to do so.
6. Look at the update window, it will say 'FINISH' after you run it about 5 minutes roughly. Your phone will reboot when it's done.
*this is the same method to upgrade to newer original LG ROM or downgrade to older original LG ROM.

##Rooting##
1. Download z4root, transfer to phone and install.
2. Set to USB debug mode in setting.
3. Load z4root, and click permanent root (it is still unrootable). It should take less than 5 minutes.

Flashing with Custom ROMs
##Things to download##
1. Download .void ROM.
2. Download Terminal Emulator and install on phone.
3. Download Custom Recovery Tool Image and its Flash Image, and put them into SD root (the main folder of SD card). Remember, the *.img file, not the *.zip file.

##System Recovery and Flashing##
1. Load Terminal Emulator on phone.
2. Type "su" (without quotes) and press enter, the $ should now become #.
3. Type exactly what is in the spoiler, down right to capital letters and spacing. Line by line (rotate your phone horizontally for easy view).

*an error will appear when you register the 4th line, it's OK so leave it be.

4. Switch off the phone after completion. Now, reboot into recovery mode by pressing and holding power button, volume down button and home button. Use volume button as up and down keys, menu button as Enter/Yes.
5. Run Nand Backup External
6. Run Partition SD card. You must do each menu available step by step (the last step would be ext3 to ext4).
7. Run Wipe All, then reboot.
8. Connect the USB to your phone, transfer the .void ROM (zipfile) to SD root. Disconnect the USB cable, and reboot.
9. Boot into System Recovery again (power, low volume and home button).
10. Select Flash menu, choose the .void ROM, and initiate flashing.
11. Reboot, and this time it will take a while (around 5 minutes for first boot).
12. Should be running on .voiD (or any custom ROM) by now.

3. Install msxml.msi, and load DZ_FW_UPD.exe.

Added on January 26, 2011, 9:30 ambcuz i dun get any errors when i type those commands except the 4th one.

after u type all, at the recovery boot up, u will see Bad boot message or something and that is normal...i was like O.o when i saw that msg and even more when i couldn't do nandroid + ext backup... btw, nandroid + ext backup, wat does this do? it backs up the whole ROM or apps/contacts/data?

Added on January 26, 2011, 10:02 amnevermind, found out already, it backs up contacts/sms and blah but not ROMs

5. Load the firmware downloaded earlier, and launch the update. The phone will display EMERGENCY MODE! sign, but it's supposed to do so.
