This is my first time to told you how to manually update LG Optimus 2X to Android 4.0.4 ICS V30A ROM.

Before starting the process, you need to understand one thing: I’m not responsible for any damage or brick of your LG Optimus 2X, you are doing this at your own risk!


How to manually update LG Optimus 2X to Android 4.0.4 ICS V30A:

  1. Install B2CTools LG
  2. Extract the (ex.: C:\KDZ\)
  3. Install msxml.msi (located \KDZ)
  4. Extract to the same folder as KDZ (ex.: KDZ\WindowsEnabler)
  5. Run LGMobile update (must be on your desktop) and install the usb drivers
  6. Reebot your LG Optimus 2X in SW Upgrade mode (remove the battery, turn on the device and hold the vol – key)
  7. Open the Windows "Device Manager" > Modems > disable the LGE Mobile USB Modem
  8. Double click to run KDZ_FW_UPD.exe
  9. Double click to run Windows Enabler.exe
  10. After run the app, an icon will appear on your tray, single-click on the icon until the "ON" text appears over the icon
  11. Go back to KDZ, locate press on the yellow folder and locate the .kdz file that you want to flash
  12. In the software window, type must be "3GQCT" and phonemode "DIAG"
  13. Click on "Launch Software Update" and wait for about 10 minutes.

Don’t care about the error log, it’s normal.
