LG has done a great job introducing mid-range Optimus phones such as L3 into the smartphone market. Its an affordable budget android device. LG Optimus L3 e400 is one of the best entry level android smartphones available on the market. It has got some cool features and specs like 800+Mhz processor , Adreno 200 GPU for gaming ,which most of budget android phones lack.It has a 3.2" QVGA screen. Touch Screen Quality is good. 
Need a way to maximize performance and unlock this phone. Unlock the full potential of this phone via rooting.

Here is how we can unroot an L3 easily. 

Before You Start:

  6. @Pac Man.

    is your phone a different L3 version. Like L3 400r with V11e firmware?

    One thing you can do is reinstall the LG United Mobile Driver.

    hope this works for you..

    is it working?

    did you enable usb debugging before connecting to pc.?

  10. doesn't work for me,, i get the following message when i try to install the LG United Mobile Driver--

    The setup has detected that versioin 3.08.001 of LG United Mobile Driver is already installed.

    This setup installs an earlier version of LG United Mobile Driver(3.7.2.0)

    You will have to uninstall the previous version before installing this version.

    1. You can easily unroot your l3 to revert back to original.

      Dowmload Gingerbreak apk and copy to root of your sd card. Enable usb debugging and unknown sources.

      Using file manger install the apk. After installation hit unroot on the app and wait till it finishes

    2. One more thing .

      NEVER FACTORy RESET WHILE THE PHONE IS ROOTED, YOU MIGht End up with BOOT LOOP.

  89. Hello Vishnu Nandan, of course i've the same problem of most of the other users (except for pac-man...., at this point i don't believe he/she did it..) the "link failed" error.
    Looking into the run.sh and trying to do the commands manually (i guess you already know it) it is impossible to create the link "ln -s /data /data/gpscfg/gps_env.conf". How did you do to bypass it? The data folder is owned by the system user and it is created at boot time. Thanks.

    if you got a lot of "error: more than one device and emulator" messages, you have to unmount all your virtual devices you mount with for example daemon tools.
