Hello, I've just re-rooted my Droid X. I lost root a couple days ago because I slipped up and took the 4.5.621 update and lost root. After figuring out I could not root on .621, I used the Linux method, and got Milestone X .604 ..Now, is it possible to update from .604 back to .621 WITHOUT losing my root? I've downloaded root keeper but I just wanted to double check. If anyone knows, please let me know as soon as possible. Thank you in advance.
