I wanted to install some third-party Android distribution over my LG operating system. My Optimus L7 has been lagging since day one and I've been waiting eagerly for my warranty to expire.
People recommend CM (cyanogenmod) so that's what I'm aiming at. The problem is that the all-mighty Google (oh, the irony!) provides so much information on ways of replacing vendor OS that I'm getting lost. Some methods require connection with PC, some just an SD card, people are booting from recovery or using installers.
Even cyanogenmod's official wiki has two articles:
http://wiki.cyanogenmod.org/w/Build_for_p700
http://wiki.cyanogenmod.org/w/Install_CM_for_p700 !
What is the difference from building and installing, which recovery to use, do I do it manually or use some installer (if it supports my model) and what are the risks? I am really not willing to dive into this unprepared and brick my phone or something. The reason I'm trying this is I can't buy a new one, and I don't want to mess up the one I have.
