[q] convert user app to system app
I'd like to know how to move some user apps stored in /data/app to /system/app, and don't get force close. I tried with link2sd, romtoolbox, rootexplorer, but always got fc.
I've deleted a lot of system apps and I want to use that unused storage for some user apps.
I hope you understand what I want to do.
Anybody can help me?
