How to Root the LG Optimus L3 E400

In this year’s Mobile World Congress, we saw LG showing its intelligence by launching three new smartphones under its L lineup to capture all three segments of the market–high, mid and low. The LG Optimus L3 falls under the mid range by providing users the experience of Gingerbread OS and not damaging their pockets at the same time. The phone’s got quite a good configuration-a 800MHz processor, 3.2″ inch screen and all that traditional connectivity options. If you have purchased this smartphone and looking for a way to root it, we have something good for you. In the following guide, we’ve explained all the steps you should follow to root your LG Optimus L3 E400 smartphone. Follow all the steps carefully and you should end up with a rooted device.

I. Before You Begin:

1. Rooting voids the warranty of the device. However, you can restore the warranty by unrooting the device.

II. Downloading Required Files:

1. Root Package (Download link’s given in the first post)

III. Rooting the LG Optimus L3 E400:

1. Download and place the Root Package archive on your Desktop.

2. Extract files from the archive to your Desktop.

3. Enable the USB debugging option on your device by heading to Menu>>Settings>>Applications>>Development>>USB debugging.

4. Connect the device to your PC via USB cable.

5. Double-click on the run.bat file you extracted from the archive.

      U need to flash a different stock Rom with kdz updater, the one that you can root is V10i, search Google for the kdz updater and stock Roms for this phone, this worked. for me. once done, root again using these steps above. 🙂

      • Ahmad Shumayal

        Problem 🙁
        V10I isn’t available under the country from where I purchased this phone LG E400
        Will it be safe if I use under some other country like India?
        Thanks! Please help!

    Hi,, I am Jayr from philippines. I just want to ask about the new version of android for my phone LG E400. Actually I already executed every steps and i follow it. I already installed Clockworkmod Recovery for my phone and also the cyanogenmod-9-ice-cream-sandwich into my phone. I did it and it works, but my Play Store and Market does’nt work properly. When i click the icon of the Play store and or Market it will fade. I dont know how to fix it.

    My question is. Is there any possible Way to fix my Play Store and or Market so that I could download and install my social network like facebook and many more. Since i cannot open my Play Store then the rest as follows.

    • Ken Okech

      Try searching ,for the “Google Apps .zip file ” and flash it via clockwork mod everything should then work

  • katherine

    whats the difference between unroot and rooted android phone? and how does it look like, i mean the interface of a rooted phone?

    • Ken Okech
