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. Make sure LG Phone USB driver is PROPERLY INSTALLED.
4. I will not be held responsible should anything undesirable happen to your phone.

Firmware & Rooting
##Downgrading firmware##
1. Download v10c here.
2. Download and extract LG KDZ Updater.
3. Install msxml.msi, and load DZ_FW_UPD.exe.
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 'COMPLETE' 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## (I'm using VOID ROM as example)
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.

Seems like Imageshack has issues to view jpg files

Working on it, but I'm busy lately, you can contribute by PMing me

There are slight differences between the original P500, Optimus T, Optimus S (in the layout). But they all are the same phones.

And guys, state your phone color and what LG version/ROM you are using

mine so far so good, nothing problem occur,

can someone describe more detail about this phone.. advantages & disadvantages.. the performance.. scrolling.. gaming.. browsing..

coz one of my frenz would like to get this one..

You can read about the advantages and disadvantages when you compare to other phones. I guess one of the advantages is the price.
Browsing is smooth even with stock LG firmware, with custom ROM it'll be super smooth.
Same goes to gaming, most games are smooth but there's a bug where the CPU will spike after touching the screens too much, but there's already a fix for that (unofficial).

Not working for me after i hv tick both phone & sim.

did u synchronize ur phone contact to gmail account?

@mush:
stock rom 10e, black

Red model, void #echo.

Looking forward to flashing void #f when it comes out. Anyone else managed to OC it past 730mhz? I'll only OC it to 730mhz when I need it for gaming. Otherwise it's not very stable, at least for me... Random reboot and freeze.

I have no problem in OC to 730.

I have no problem to operate at 730Mhz too. Even the battery drain is not as bad as I thought it would be.

Btw calson, do state your phone color + ROM

gratz mushy finally create this thread for lg optimus 1
my phone is red colour,rom v10e ~

I think so, how to check?
