Hi just joined today as I have a specific question which maybe frowned upon but it is a legit question. Used to have a HTC Sensation SE which was registered on the Andriod device Manager service. This phone has been passed on to my wife but when setting up my new HTC One in the device manager I now have two devices showing. TheSensation had a factory reset when I gave it to her and now it shows that it was unable to track and tells me when it was last used. My question is can this be registered again for her use or will it be forever in limbo.
