I don't know if someone already rooted my Samsung Sm-t530. Can somebody help me?
I just find some files like
Knox emulated Emulated Extsdcard Sdcard Mnt Storage/emulated Dev/emulated
And i cannot find Imei.
Download a root check app or look at your settings and see if you have anything like supersu installed. There is many root check apps on the play store which you can use. You can check your imei number in the phone near the battery (or under the battery if it's a removal battery).
Download Root Verifier app from google play store and it will tell you whether or not your device is rooted or not?
either you use a app to check if you gained root:
i would advise Root Verifier, it is free (as in beer and speech), ad-free, uses no further permissions and also checks for
busybox and a superuser-app.
or on the other side, you can simply check it by terminal with the
but i would only recommend this method if there is a terminal-emulator already installed, you need just a quick check once and you know what are you doing with a terminal...!
if you need additional identifiers (like the IMEI) i can advise Get ID; it displays
and in the help-menu a little explanation for every entry can be shown.
