Hum, I have problems downloading, or unpacking or something, the zip archives. What've you guys used to download and extract them with? I've tried FF and IE for downloading and 7-zip, WinRAR and Windows' built-in. All this on both 32- and 64-bit W7. It only say it's empty all the time.

Edit: Got it to work - no clue why though Ah well, thanks a lot for providing this bundle!

With help from people on here, and with some reference from a very useful guide I found on another forum, I finally have 2.2 working sweet and the cpu over clocked.I have had a fair few problems so for those fellow newbs who dare to try it I shall post the guide along with my own added info on what to do if things go wrong.

The guide is from a forum post at the android forums,it is NOT my work, the added bits are mostly what I have found from browsing here and from asking questions. While I can't be held liable if you mess your phone up having done so myself I thought this could helpa few people and save them searching various threads for answers so hope it helps
The guide

To install this ROM you need to have fastboot enabled on your phone. If you have Android 1.6/2.1 installed from LG, then fastboot is not enabled. I will explain how to enable fastboot on your phone (this involves re-flashing/replacing your currently installed firmware):

KDZ Updater CarphoneWarehouse Unlocked.zip - A link to a zip archive with all the files needed to flash to Android version 2.1 with fastboot (Carphone Warehouse Unlocked)

KDZ Updater Europe Open.zip - A link to a zip archive with all the files needed to flash toAndroid version 2.1 with fastboot (Europe Open)

Download the version that best applies to you, if you live in the UK, I'd recommend you download the Carphone Warehouse Unlocked version, whereas if you live in Europe, I'd recommend the Europe Open version (simple right?  )

I live in the UK and used the open rom from Europe as the Carphone Warehouse rom would not install

Now, how to flash these versions; I'll explain in detail how to flash the ROM's from starting with backing up.
Instructions to install ROM with Fastboot:

1. Before you start, make sure you backup all your data by installing the z4root.1.3.0.apk file onto your phone, then open it and choose 'Permanent Root'. Your phone will root and reboot. Then go to the Market and install 'MyBackup Root', open it and do a backup of your apps and personal data (contacts, sms, call log etc.) Once this is done, go to Settings>SD Card and Phone Storage>Unmount SD Card, a notification in the notification bar should appear saying 'SD Card safe to remove'. Remove the battery cover and remove the SD card and store it in a safe place. Then continue to step 2.

2. Extract the .zip file you downloaded to your computer (e.g. your desktop). Open the folder and install MSXML 4.0 SP3 Parser (msxml.msi).

3. Once that has finished, install LGAndroidDriver_WHQL_ML_Ver1.0_All_Win7.exe which are the drivers so your computer will recognize your phone.

4. Next, open KDZ_FW_UPD.exe
(i) Change 'Type' to '3GQCT' *THIS IS A MUST, THE UPDATE WILL NOT WORK OTHERWISE AND YOU MAY BRICK YOUR PHONE*
(ii) Make sure 'PhoneMode' is set to 'DIAG'
(iii) Browse for the 'V20B_00+Fastboot.kdz' file.

5. Prepare the phone by enabling USB Debugging by going to Settings>Applications>Development>Enable USB Debugging and connect the phone to the computer via USB cable and wait for the drivers to install for the phone.

6. Click 'Launch software update' and do not use your computer until the update is complete. The update will take roughly 10-20 mins to complete.

If you have a problem with this try a different rom, this guide offers two to choose from.
Instructions to install CyanogenMod:

Once the update is complete, your phone will reboot, what you need to do is power off the phone and whilst the phone is off, press and hold the 'Camera' button all the way ANDpower on the phone, make sure you hold the 'Camera' button. The phone will display the LG logo and disappear, then display a blank screen. The phone is now in fastboot mode!

Now you want to download this file: Flashing CyanogenMod.zip and extract it to a folder called 'Android' (without the quotes '') on the C: drive (you'll probably need to make this folder yourself.

1. Now open CMD with administrator privileges (Search for CMD in the start menu and right click on 'cmd' and click 'Run as Administrator' )

2. Connect the phone to your computer via USB cable and wait for the necessary drivers to install.

If when connected with a usb cable the computer says "waiting for device" and nothing else happens try installing the fastboot drivers a helpful forum member posted and which are included as an attachment in this post. You can do this by going to the control panel of your pc, from the Windows start menu, opening the list of devices and where you see the one representing your phone (likely, as was the case with me, it will say android and have a yellow exclamation mark over it). Different versions of Windows do things slightly different but what you need to do is simply update the driver by choosing the icons properties box choosing UPDATE or INSTALL DRIVER and when asked pointing it to the folder where you unzipped the drivers.

3. Then go back to the cmd window and type:
Code:
cd  C:\Android
(i) Then type:
Code:
fastboot.exe -w
(ii) Once that's completed, type:
Code:
fastboot.exe erase system
(iii) Once that's completed, type:
Code:
fastboot.exe flash system system.img
(iv) Once that's completed, type:
Code:
fastboot.exe flash boot boot.img
(v) Once that's completed, type:
Code:
fastboot.exe reboot
4. Your phone will now reboot with CyanogenMod 6.1.1 (Android 2.2.1). The first boot might take longer than a normal boot.

If your phone stays at a blank screen you simply forgot to do one of the above steps, in which case simply repeat them. It is likely if that happens that you simply forgot the flash boot image instruction.

5. You can now re-insert your SD card and go to Settings>SD Card and Phone Storage>Mount SD Card
Enjoy!

The instructions for flashing both the firmware with fastboot and flashing CyanogenMod are included in the zip archives called 'Readme'. I'll update the links so that you'll always have the most up to date version of CyanogenMod available for download, note that if you choose to update your phone you will loose all your data including apps etc. so backup before you update
And that, with a few comments added by myself, is the guide.

Once you have set your phone up the way you want power off your phone. Hold the HOME and POWER buttons down while the LG logo appears and you will see a menu appear on screen.

Using the volume down key to navigate the different menu choices, and the camera button to select an option choose the BACKUP OR RESTORE option and from the sub menu that it will give you choose BACKUP.

This will make a backup of your phone AND all your data, if you ever mess up an update or think you have damaged your phone in the future simply holdthe POWER and HOME buttons down and when the menu appears choose the RESTORE option

I did everything till fastbooting, when im doing fastboot flash system system.img it says fail bla bla too many links;
so then i bricked the phone i think, but i re install the europe + fastboot and got my phone to work on 2.1;
now i dont know what the problem is, it may be the command fastboot erase; or maybe that im working on 64 bit win 7; I realy dont know. please help if you can

You need to get the Virgin Mobile APN settings, from h t t p://www.virginmobile.com.au/, search a similar phone to the GT540 and copy the settings manually.

Any queries, contact me

Thanks for the guide, and files.

Little warning.. The Fastboot USB driver only seems to be for x86 systems and will not work on x64.
So make sure you have access to a 32bit windows system before starting..

Unless someone knows where to find a x64 version of the Fastboot USB driver.

So far I am loving this Cyanogen stuff.. =)
