yes,I installed it rooted.
The document in the software told that I should follow the guide below to uninstall it.

But since I follow the second way to use the ConnectBot,I still don’t know the apk’s name of the Anti-theft.
(I enter the command “mount | grep system”,and it returns “grep:not found”)

By the way,can I remove the software by using Titanium backup or link2sd?
Does it anything different from the guide?
