You can root anything running Linux (which is the OS in Android) or any *nix variant, even a microwave oven - if you can find an exploit that gives you at least temporary root, since you have to be rooted to root. Towel Root basically crashes Linux in a way that makes it come back rooted, long enough to shove a system file into it - which means that it's rooted. (Don't think that's easy - the reward geohot was due [I don't know if he accepted it] for finding the exploit was huge, but probably amounted to less than minimum wage.) The rest of the stuff, installing busybox as a system file, installing a Superuser app, etc., can all be done once that file is available. (As Linux comes, that file - su - is part of the package. To run as root, you just type su command instead of command ([it'll ask for the root password, one of the things we don't want in a phone we want to give permanent permission to an app to use su, which is where the superuser app, like SuperSU, comes in - we don't want any app to be able to gain root by itself, or every virus would be doing it] and the command runs as root. Which is all you root a phone for - to be able to run apps as root.)I THINK you can root any android phone.
There is a one click solution for the boost mobile volt, I rooted my phone with it a few weeks ago. Just google LG Volt rooting guide.
