How do I root my 4G LG Motion? How do I root my 4G LG Motion? I have an app that needs root access, but I don't know how to root my phone. Also, I REALLY want this app so.... If you know please help.
According to OneClickRoot, their tool is supposed to work for the LG Motion 4G. You can download the tool from their site, and they even offer a "remote rooting service". In addition to that tool, you will need the appropriate drivers for your device, which you can e.g. find here. Having that installed, it should be as easy as: Start the tool, connect your device, click to root.

Another rooting guide is offered by AndroidForums (the article links all software needed, including the drivers), which uses the O4X tool from the XDA developers (I used this succesfully on my O4X -- seems like it also works on your Motion 4G). Steps included are also pretty easy: Having installed the drivers, unpacked O4X, and the additional *IS11LG_SystemBackupTest.signed.apk* from the XDA post, you go to Settings&rarr;Security on your Motion, and tick unknown-sources. In Settings&rarr;Developer Options you enable usb-debugging. Then you install and open IS11LG_SystemBackupTest.signed.apk, and finally restart your device. Once phone turns back on (should be running slow) connect your phone to your computer through USB (charging only). Open the command prompt and enter cd C:\o4xr, then type root. Next wait for the script to run and your phone will reboot; when that happens uninstall the SystemBackupTest app. DO NOT OPEN IT, or you will have to repeat the entire procedure :)
