Hi, I've been putting myself thru the Android School of hard knocks with donated old phones from coworkers and friends. Got to admit that the Spectrum has had me beating my head on my desk. I've rooted,trashed,repaired this one several times. Probably should be arrested for rom abuse. Been looking for custom recovery and trying a few (trashed again). Will this work on Android 4.0.4 V9? If so,correct way to install? The LG software repair tool is getting tired of me.
