I've just rooted my n9005 and installed cerberus in system-apps so that it doesn't get wiped out on factory reset. I am using the stock 4.4.2.
1) The problem is that every time I try to track my phone the GPS icon pops up in the notification bar. Moreover, when I roll down the notification bar and press the location tab, it shows some suspicious app trying to get access to the location (System Framework) which may alert the thief. Is there any way to get rid of the location/GPS icon and hide it in the location settings?
2) Is there a way to prevent the thief from flashing a new rom? I remeber reading about some usb-debugging lock but not sure how helpful that would be.
