You can actually get a command line on Android, and issue commands as root?

You can actually get a command line on Android, and issue commands as root?

Both from a computer adb interface, or you can download a terminal app, running straight on the phone. With root. However, if you get the malware, I would hazard a guess that it would be smart enough to block, or at least back itself up (similar to the sys files in the factory reset), removal of itself via command line.

And of course, anyone smart enough to do that (much less actually modify files to fix the problem) likely already has the knowledge/ability to reflash the ROM anyway.
