Installing Linux on Android usually requires rooting your device first. If that's not an option for you, then the GNURoot app is right up your alley. Despite its name, GNURoot doesn't require root access in order to run.
I do not know exactly how rooting works or if it can even by done on my Android (Samsung GT-N8013) device. No rootkit appears to exist yet for Android 4.1.2, so I am left with figuring out how to root my device via other means.
All I would like to do is do certain operations (on my own device!) e.g. read a file regardless of its permissions or run certain programs as root.
Before i begin i am a new user here so if this is in the wrong fourm please move it.
I am a 2 year android user and i have never tried rooting and i would like to know if there is a way to root my device the LG L9 p768f Android verison 4.0.4
*when i root do i have to install a custom rom ?
If you would like to root your Android device and don't have access to a PC there is a great new rooting application called TowelRoot. This by far is my favorite even above the poot debug method because it has just as many if not more compatible devices and even easier to use.
