How to Install the Official Gingerbread to LG Optimus One

Want the official Gingerbread Firmware from LG? Get it here and learn how to install it to your phone.

Gingerbread is not yet the perfect OS (sill got bugs) hence Ice Cream Sandwich is on its way but nevertheless way lot better than Froyo. But before anything else, do a backup of your data, if your rooted use Titanium backup, if not MyBackup Pro will do. Here’s how:

  1. Download the Gingerbread 2.3.3 version from
  2. Download LG’s firmware updater application appropriate at your PC’s OS KDZ_firmware_updater. Extract it to folder and install msxml.
  3. Connect your LG Optimus One and run KDZ_FW_UPD.exe Don’t turn USB Storage on your phone.
  4. In the software window, choose TYPE as 3GQCT and DIAG for the PhoneMode
  5. In the KDZ File, click on the folder button and look for the firmware you’ve downloaded in Step no. 1
  6. Last step Click on the Launch software update button, don't unplug yet the USB Cable wait for it till it finish its job. Don’t worry if your phone flashes “Emergency mode”. Reboot. 

Check on the settings your android version. You can now enjoy Gingerbread. But one drawback though you can no longer root your device once you flashed it with the official one. Another downside is that this version doesn’t support USB Storage which I know that almost Gingerbread doesn’t have.  Otherwise you need to downgrade your device back to Froyo and install Cyanogenmod version instead.

Major Differences from Cyanogen: 
  1. Better handling of gallery.
  2. Same interface from Froyo Firmware.
  3. Does not support Tweaks in Settings.
  4. Faster connection manager.
  5. Touch screen is not that snappy compared to Cyanogen.
  6. Does not crash compared to Cyanogen.
  7. Moving of applications to sdcard is limited unlike in Cyanogen.
Please leave a message on how it goes for you and feel free to ask if you have some questions.

Update: You can still root your device by downgrading your device back to Froyo. Follow the instructions
If you don't have USB drivers get it here.
