Easily resize system + data partitions
Seen this on XDA and thought I would share it, works on my phone, and I have over 100MB left for apps.
Note: This will resize the system and data partitions to allow more space for apps by taking some space from the system partition on the phone
BIG THANKS TO MUR4IK FOR THIS TOOL! Be sure to donate to him and support his work!
Cannot get the builder to run or use Linux/Mac? Solution here!
In this guide I will be showing you how to resize your data + system partitions for more/less space.
Things you will need:
LG GT540 w/ A Fastboot ROM installed
LG drivers and Fastboot/ADB drivers installed
Windows (with .NET Framework 3.5 SP1 installed. If you have trouble launching the program, (re)install .NET 3.5 SP1. Also this tool will not work with Wine on Linux.)
Your phones USB cable.
WARNING: MAKE SURE TO NANDROID BACKUP YOUR ROM BEFORE CHANGING THE PARTITION SIZES! YOU MAY NEED IT LATER. ALSO, THIS TOOL DOES NOT REMOVE RECOVERY.
First of all, grab the SwiftBootloaderBuilder.zip from SwiftDroidSite or from here.
(Mur4ik's site is recommended)
Next, put your phone into Fastboot Mode (Camera+Power)
Extract the files to your Desktop using any archiving program. Then go to the folder you extracted. Right Click and Select 'Run as Administrator'
You will see a window like this pop up:
Now we can alter the partition sizes. If you want the same effects as Mur4ik's 234MB DATA KDZ, choose 150MB system, and the data column will change accordingly. If you want a bit more system space (eg. To run airbus360's LG Optimus One ROM) Select 190 system. Basically, adjust the settings to how you want. My recommendations are:
For SwiftDroid, joe.stone AOSP, airbus360 AOSP, EleganceSwift, MMXTREM 2.1 Lite, Quarx Black ROM: 150 system 234 data
For airbus360 Optimus One: 190 system 194 data
For stock 2.1: 250 system 134 data
Once you have decided on the size you want, hit 'Flash New Bootloader' and confirm you really want to do this. You will get a 'Done' message and then click OK. Select 'Wipe Data' and then Reboot Device. After you click reboot, hold down HOME until recovery pops up.
Now you have two choices. Either install a new ROM from scratch, or restore your nandroid backup you made earlier.
This tool also has the option to remove fastboot and recovery from the device, so you can return to stock firmware, and possibly use regular LG updates again.

Thanks to Mur4ik for making the program for this method, and thank you to effortless on XDA for posting it.
Oh and I found that after this fastboot instaid of showing a blank screen it shows a blue one and shows what is being done through fastboot, but it seems to work all the same.
