[Galaxy Ace S5830 Original Android Development] CJCord:
Ok. found problem whith adb not able to see /data. easy and simple: enable root for ADB in "Options" => "Developmentoptions" (or similar)

i also found that when trying to open "Google Login Service" in Dev Tools section it crashes

Logcat started before opening, and closed after window about "process died" was closed:
