[GT540 Optimus General] bretthutton:
Brief: Back up All - Contacts & Data (Remove Sim Card)

[Unlock Phone] [Install 'z4root.1.3.0.apk' 955.48kb] [Install 'Rom Manager' Android Market][Install 'Superuser' Android Market]

Ok the way we are doing this is

2.1 -> 2.2 fastboot -> 2.3.3

Start -

First Install Driver on PC:

'LGAndroidDriver_WHQL_ML_Ver_1.0_All_Win7'

Download this Link to PC: KDZ Updater Europe Open.zip 144mb

Put your phone into Download Mode

1. Take out 'Battery'

2. Put in 'Battery'

3. Hold down 'volume down' and hit 'Power-on'

4. The screen should display 'Download mode'

5. Plug in 'USB'

Extract KDZ Updater Europe Open.zip to your PC/Laptop

1. Run 'kdz_fw_upd'

2. Choose '3gqct' as the 'Type'

3. Choose 'Diag' as the mode

4. Click 'File icon' and select 'Europe Open+Fastboot.kdz'

then hit Launch Software Update

Please note: that you DO NOT have to let this flash finish (BUT IT IS EXTREMLY RECOMMENDED.. takes forever on this rom tho lol)

as we only need the fastboot part of it so leave it flashing for a few mins then remove the phone the updater software will come up with a few errors but just ignore them

Ok now we need the latest Recovery version of the swiftdroid software

Since i used 1.8 i will use this in this tutorial

Download Gingerbread 2.3.3 SwiftDroid_v1.9 95.2Mb

Ok extract the above file to your Pc/Laptop

Now take the 'update.zip' file from extracted folder and copy it to the root of your phones 'SD card'

Now put your phone into fastboot mode

1. Take out 'Battery'

2. Put in 'Battery'

3. Hold in 'Camera button' and press 'Power-on'

4. Keep camera button pressed until 'logo' disappears and it shows a 'blank screen'

5. Make sure phone is plugged into USB

Now open where you extracted folder the above archive (Gingerbread 2.3.3 SwiftDroid_v1.9)

1. Open 'CMD' within folder

2. Type 'flash_recovery.bat' to run

What this does is flash cyanogenmod recovery to your phone

which is a great tool for updating firmwares and restoring from bricks

Now we will put the phone into 'recovery mode'

1. Take out 'Battery'

2. Put in 'Battery'

3. Hold down 'Home button' and press 'Power-on'

4. Keep holding down the 'Home button' until the cyanogenmod recovery menu pops up (it takes a while.)

Now to install the 2.3 rom

1. Press the 'volume' down until 'install zip from sdcard' is selected

2. Then press the 'camera button'

3. Then press the 'camera button' on 'apply /sdcard/update.zip'

4. Then Press the 'volume' up and choose 'yes' and press the 'camera button'

Now this part will take a while (around 5-10mins)

it will say flash complete! when finished and will return to menu once done.

Menu will come back up...

Hit your 'Back button' and select 'reboot system now'
