What is needed?
2. One of the flashers (depending on your device) from the following post: Flasher
After you have both extract the flasher using Winrar. Next place your rom in \LGMOBILEAX\Phone. After that navigate to LGMOBILEAX\SmartPhoneSetup and open SPConf.ini with Notepad. You will see a line called DZNAME =. After the = sign insert the physical name of the rom you placed in the Phone folder. Make sure you have the dz extension at the end. Also make sure there are no spaces in the name of the rom. There is also a line called SWVERSION. You can change that to whatever you want as long as there is no spaces. After you are done with editing this file save it.
Next right-click on the LGMOBILEAX folder and choose Add to Archive. Now name the flasher what you want and then check Create SFX Archive. After that click the Advanced tab. Click on SFX options. Now set path to extract to "C:\Users\All Users" for Windows 7 or "C:\Documents and Settings\All Users\Application Data" for Windows XP. Also set Run after extraction to "LGMOBILEAX\SmartPhoneSetup\SP_Starter.exe".
Note: There are options to set icons, pictures, and text in the installer, but is not necessary. If you want to play with that you can by going to the text and icon tab.
Now that you have all that set click ok and then ok again. It will start to create your flasher. IOnce it is done all you need to do is run it.
