So ADM is officially "out" but reading on another site, there were a lot of people having issues. I thought I'd be proactive and post something about how to get it to even show up.
There are two things that you need to check -
(1) In "Settings", "Security", "Device Administrators" - be sure to allow "Android Device Manager".
(2) Go to "Apps" and find "Google Settings". In there click on "Android Device Manager" and make sure that at least "Remotely locate this device" is checked. Check "Allow remote factory reset" if you want to be able to wipe the device remotely if you lose it.
Here's the issue I had : Android Device Manager didn't show in Google Settings. So I opened Settings and scrolled down to Google Play Services. I cleared the cache and rebooted. Once my Thunderbolt got back up, ADM showed in Google Settings (both options were already checked btw).
My next issue was that the website still isn't showing my phone. According to this page, you:
(1) Go into Google Settings, Android Device Manager and un-check the option for remote reset.
(2) Then you go to Settings, Google Play Services and Clear Data.
(3) Then you re-enable remote wipe, reboot the phone and wait 5 minutes.
(4) If the above steps do not work for you, go back to ADM and uncheck both options (locate and remote wipe), then repeat steps 2 and 3. On step (3), locate may already be checked after clearing data.
Go to https://www.google.com/android/devicemanager and your device should be displayed
Note: Google Play Services has to be v3.2.25 or higher
