I'm putting this together because I had a hard time finding the bits and pieces of info I needed to root an LG Optimus V in Linux, and I was hoping I could direct others to the sources of information I found most helpful...
Using these instructions, you should be able to successfully get permanent root access to your Optimus V in Ubuntu Linux.
- Download the Android SDK. You'll also need to launch the manager ("android" in the tools folder) and download the platform-tools package, which contains adb.
- I don't know if it's necessary or not, but this page has some instructions on restarting the adb server to be able to use it as a regular user. Note that the commands should action be "./adb kill-server" and "./adb start-server"
- This post has some instructions on pushing and running the psneuter exploit. I grabbed psneuter out of the SuperOneClick package. Note that the instructions for remounting the filesystem differ from the Optimus-specific instructions I found, so I only link this page for the psneuter instruction.
- The most comprehensive post I found specific to the LG Optimus V was here. It's basically a copy of a post from AndroidCentral, but you don't have to register to use the links. There's also a zip file attached to this page containing the "su" and "busybox" files you'll need to push. Use steps four and five from this post.
(Note that there's always a change you'll brick your phone by doing something stupid, so using any of the instructions posted or linked to in this post are completely at your own risk.)
