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.
