How to Tether/How to Root - Guide to Tethering/Guide to Rooting: The LG Optimus Extreme (LGL40G/L40G)6:21 PM
So here is my complete how to/tutorial on all things wifi hotspotting/wifi tethering with the LG Optimus Extreme (LGL40G/L40G) with Android ICS 4.0.3, right down to rooting this phone if need be and getting wifi hotspotting/wifi tethering going with superuser access. I have taken as much care as possible to make all the steps easy to follow and accurate. Please make a backup of your data before embarking on this journey. Also note there are currently (to my knowledge) no ROMs available for the LG Optimus Extreme (LGL40G/L40G) as of yet, so rooting is purely for the purpose of gaining administrative access for the usage of superuser apps.
