ok so what im trying to do, is make my phone faster, and have better battery life, i've been reading up on some stuff and New Optimus as kinda given me some ideas. I was checking into the CTmod and i think that the route im going to take. So i was wondering what steps i should take first. How should i back up my phone incase i screw something up? And i would also like to use the back door mod, i should do that afterwards right? im posting this cuz the wifi tether is what im currently using for internet so i only got one shot. someone help me out, how should i go about this...step by step maybe? Edit: i keep seeing ppl talk about shabbymod, but i cant find anything on it. what exactly does it do, from what i gathered shabbykernal closes the remote access back door right?
