I hold the camera button and push power on... The phone vibrates a bit as it usually would and then nothing happens (you say its it fastboot mode) no screen light comes on, no logo, nothing. I plug the phone into the computer where the command prompt is waiting for the device, nothing happens. I unplug the phone and try to power up (or down) nothing happens so i have to take the battery off the phone to get it to start again as normal.
I seriously hope theres something i'm not doing right here.... How long would u say i have to hold each button for? Should it be plugged in before i do anything, or plugged in after i get the vibration?
hey dudeman i see your running 2.3 whats the crack , is it finished. hows it better than 2.2
http://androidforums.com/lg-optimus...-android-2-3-avaliable-gt540.html#post2270185 it's 95% finished, just 2 or 3 missing features but other than that perfect! Definitely better than 2.2 
I've done everything as in the tutorial (used europe open), pressed launch update and it said this:
[R&D Test Tools Log File]
20:09:52 : Launching SW update
20:09:52 : Unpacking KDZ
20:09:54 : KDZ file extraced
20:09:54 : Extract file error
20:09:56 : ===FINISHED===
Halp?

I got a couple of questions before I attempt to upgrade. (I'm a noob)
1. What is flashing and how do you flash fastboot?
2. Will this upgrade erase all my data?
3. Will all the highscores/achievements, etc. on my games get resetted?
4. Is it worth getting this upgrade or should I wait a little longer?
Please answer and thanks for taking your time to read my post![]()
What is flashing?
- Flashing Firmware refers to the microprograms present on ROM (Read Only Memory) modules, which contain low-level (e.g., hexadecimal, machine code) software. They enable the device on which they are present to take stock of its capabilities and to render those capabilities functional.
How do you flash fastboot?
- See page 1 of this thread
Will it erase your data and your gamescores?
- Yes, unless you back up your data, about gamescores, they'll be gone , and you will have to reinstall your games
Is it worth it?
- Yes, but i'd recommend you to use the CM7 'cause this CM6 it's no longer being developed, though it's pretty much useful
and for this link: http://www.mediafire.com/gt540cyanogenmod , do I have to download everything? If so, what's an easy way to download everything without making a premium account? (My computer is slow). + how do I flash fastboot? Btw, I live in Canada so do I use the CPWH KDZ Updater or Europe? I have an English version but do I need to use those two or can I use the English version instead? That's all I need to know. For now.
in the CM7 thread dudeman1996 made a bat file to automatically install the ROM onto the phone. so you only need to download the updater, and the drivers from LG for your OS (XP or 7) i used the carphone warehouse updater , i live in mexico, so am guessing that one will work for you too.
in the thread look for Instructions to install ROM with Fastboot
click the "show" button below that text.
Where do I get the bat file?

One last question for now, will all my Wi-Fi data get erased too? and is there a way to backup and restore it? Because I have a lot of Wi-Fi places or whatever you call them.
Everything gets erased yes, I think if you use My Backup Root then it should be able to backup all settings including your Wi-Fi places.
I just used that to backup my stuff but the apps I linked to the SD have an error. I think it was for the data files only. and when I back everything up will my phone be almost exactly the way it was before I upgrade to 2.2?

It's no longer a bat file, it's now an exe file, you can get it from here![]()
It says threat found on Norton. Should I ignore it?

I'm stuck on step 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).
