Backup your phone


this is important if you wish to keep any data from your phone. You will have to restore backed up data (such as apps) after you update. The only way to update to the latest software is to erase your device, so backup whatever you do not want to lose.

Extract the .zip file, which you can download from this AndroidForum thread or this XDA thread. Open the folder and install MSXML 4.0 SP3 Parser (msxml.msi).
Once that has finished, install LGAndroidDriver_WHQL_ML_Ver1.0_All_Win7.exe which are the drivers so your computer will recognize your phone. Windows XP Users download this driver, extract the contents anywhere (e.g. desktop), right-click on the 'android_usb.inf' file and click 'Install'.


Now you have set up your phone to connect to your computer correctly. From here on, it depends on which ROM you wish to install. This is an excellent video tutorial that covers installing custom ROMS and rooting, and as said in the UPDATE, many ROMS with instructions can be found on XDA.

Bricking is always a possibility when modifying software that doesn't come directly through the intended channels

That said, the methods here have been proven to work and your risk is significantly less if you perform these steps correctly.

UPDATE: this is a method to install updates to your phone. as far as specific ROMS to install, XDA and google can be very helpful. As soon as you find one you like, go for it :)
