so i am buying a rooted dx tomorrow. I dont know how the guy rooted it or what rom it is on. I am somewhat familiar with rooting but not too much. I rooted my og droid and droid eris before so i have a little experience. But i am new do the dx, and i am wondering if when i get it tomorrow can i download an app (z4root) and unroot the droid x? why you might ask? Well i want to go to stock so that i can get the gingerbread update from verizon here soon when they release it OTA. After that i was planning on waiting a few weeks until somebody has a really good and stable gingerbread rom and then root the device again. So basicly, can i unroot the droid x with an app no matter what rom is on it? and can i re-root it again once a stable gingerbread rom is released.? I have read alot about rooting the dx and people said you need something like rds lite and a whole bunch of other files and i was hoping to unroot and root with an app instead of doing all that other stuff. Help would be greatly appreciated.
