Creo que la misma app de cerberus permite hacerlo, por lo menos yo recuerdo haberlo hecho. Si eres root, que es obvio, la propia app te permite integrarse en la rom, y aunque hagas un wipe data, seguirá ahí.
PD: Extraído de su web:
"[+] I have a rooted device. Can I get additional features?
Yes! If you have rooted your device you can integrate Cerberus into your ROM and get two additional features: complete uninstall protection (Cerberus will even survive a wipe/factory reset) and GPS auto-enabling even on Android 2.3.3 and later. To have these features uninstall Cerberus, then download cerberus.zip, put it on the sd card and install it from recovery. Cerberus is also available on ROM Manager.
If that method doesn't work, you can manually install Cerberus in /system/app this way:
- Uninstall Cerberus from your device
- Download Cerberus.apk and put the file on your sd card
- Open a terminal emulator and execute:
su
mount -o remount,rw /system
cp /sdcard/Cerberus.apk /system/app/"
