I'm about to send my Droid X off for replacement under factory warranty. (keys are sticking) It's currently rooted with Cyanogenmod 7. So I'm guessing an .sbf to froyo and a factory reset should be all that's necessary to avoid Motorola finding any evidence of root. But since Cyanogenmod 7 is more of an advanced ROM in terms of features and functionality, I'm just wondering if anything else might need to be done to restore the device to factory “out of the box” condition. Some of you programming guys might be able to answer this one. Anyone care to comment here? Thanks!
