    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?

    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

    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.

    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?

    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.
