noob question here,
3. Then download the app "IS11LG_SystemBackupTest.signed.apk" from that site/post as well and copy it to your phone to the root of your sd card
what do you mean by "root of my Sd card"
i do have a question about the "superSU" step.
when i got here it didnt give me an option to update, only to open.
EDIT: NM it all worked and im rooted. thanks guys!
