good method for rooting here
http://androidforums.com/elite-all-things-root/
it will require a little knowledge in using adb,some driver downloading and installing what amounts to an edited stock rom for the elite that sets root. not to difficult. as for the theme here,the only way to install it is after rooting the device and by using file explorer to copy and over write the orginal stock files with those in the theme. cant use flashable zips yet as no recovery for the phone has been developed as of yet. and there is some risk in installing customized system apps that can cause a boot loop. its a chance you take. ive had it happen at random. so be advised. id suggest getting root,and wait on working recovery and then rom. i do know that there is a rom already done pretty much,the developer is just waiting on a working recovery to be available. without it,the elite is in limbo. and even though there are a few giving it their best,it looks dismal at this point. but atleast with root you can remove the garbage virgin mobile and lg loaded onto this phone. my gmail is :::edited::: (pm for email and help) if you need some extra help with root. i dont mind helping out.
