Dangers of switching roms? (Verizon)

[BinarySauce]

I have the xt926, and I'm interested in flashing a new ROM. The only thing that worries me is when I trade in the phone for a new one in december, will they not accept it if it's not in factory state? Is it possible to get it exactly the way it was when it arrived?

Also, where are the basic instructions for installing a ROM on KK? I rooted and unlocked the bl, but now I'm unsure what to do.... Do I need a recovery? A specific recovery? How do I use one? Should I follow the CM11 instructions here on XDA, or on the CM11 website?

It seems like everything is fragmented and the dev section is a mess....

The only thing you can't undo is the bootloader unlock. So if they're not going to take it because of that your already too late. Might as well enjoy the ride. There are several good guides on these forums for roming it. Step one learn to install a custom recovery
