    I read your article on how to Root an lg f3. good article. My computer is not available at the moment. Is there anyway to root It without a computer?

  • Ted Sternberg

    On my Optimus F3, Motochopper failed when its script got to “adb shell /data/local/tmp/pwn”: it came back with
    [+] This may take a few minutes.
    [-] Failure.

    (And it didn’t take “a few minutes” before printing “[-] Failure” — more like a couple seconds.)

    As for Saferoot, that ran until it tried “adb shell /data/local/tmp/getroot”, at which point it printed
    Your kernel is patched!
    This device is not supported.

    The last line of attack I tried was to put the thing into Download Mode. On another phone I have (a Huawei, if you care to know), Download Mode exposes all of the phone’s file systems to my (Linux) PC: I type “fdisk -l” and I see a list — /dev/sdf1, /dev/sdf2,…/dev/sdf14. Which is cool because at that point I have full read/write access from my PC. Now back to the LG Optimus F3: I got it into Download Mode (power down, wait a minute, volume-up, plug in USB cable). Unfortunately, I couldn’t see the file systems.

    This is not working for my device! I have the driver you gave a link to installed. An whenever I run it, it always ends up as rooting failed, rebooting. Will you please tell me ASAP

  • Brian

    Tricia I suggest going here and using saferoot. I couldn’t get motochop to work on mine either.

  • tricia

    does this root work on v8???

  • tricia

    every time I try to run the program I get a msg that says location is not available.. I don’t know what im missing.. can u help?

  • Kevin Stofleth

    I have just rooted my LG phone following the directions i got and nothing seems to have changed. Does that sound right? Was i suppose to do something after with my phone or the files i downloaded?

  • Richard

    Motochopper only works for v5 if you have the v6 update you will have to use safe root. If you root your phone on v5 DO NOT INSTALL the v6 update or it will brick your device!!! Need help hit us up at androidforums

  • Brian

    Use saferoot if this is failing, it’s safer anyhow:

  • Chris

    Also failed here. I have a screenshot if author is interested – after installing superuser, rooting phone, and getting the “this may take a few minutes” message, I get “failure, cleaning up, reboot” blah blah.

  • Derrik

    [@LaDerius Allen] [@Bonny Nichols] [@vegas] If motochopper does not install superuser, you need to go to the play store and install it yourself.

  • Matthew

    Had to install SuperUser myself but works great! Thanks!

  • Bonny Nichols

    Didnt work for my lg optimus f3 sane as below problems

  • Ralph Juliuson

    I have attempted to root my F-3 numerous times to no avail. Once the program runs when it is done it reboots as usual. Checking the apps the notice comes “Superuser binarys are not up to date” and any attempt to update it fails. You can still open the partitions but there is no access to allow superuser access. Any suggestions?

  • vegas

I rooted my lg motion(with less trouble) and cant help but notice the su binary doesnt load but it wont load w/o being rooted please e mail me back would really like to get this thing rooted before i chunk out window

  • LaDerius Allen

    I’ve tried using this method twice,it didn’t work… I click on run.bat(with my phone plugged in one USB debugging of course ) and I go through all the instructions and eventually my phone resets. When it does, I use the root checker app to check if it’s rooted and the app says it isn’t rooted. Am I doing something wrong? Can you please email me with help.
