Root access or SuperUser is an apk that resides in /system/app
. If you remove it with the rest of the apps, you looselose root. As a possible workaround, you can try to run:
> adb root
> adb shell
And see if the shell that adb opens is $
(normal user) or #
(root). If you're logged as a normal user, I'm afraid you will need to reinstall root in your phone.
Also, /system/app
is like C:\Windows
or /bin
(in Linux), if you remove the files there, don't expect the device to run, as it won't have the necesarynecessary files to do so.
