It's not really a problem since as long as you hack simple things like UI you cannot really botch it whatever you do, you can always restore things like thy were under 60 seconds if you totally mess it up. Here's how to do that;1.) Always tweak the device by ssh'ing to it, not from fingerterm. Then it does not matter if you break the UI. I use WLAN myself but of course you could ssh in via USB if that's your thing. 2.) Always take backups of the files you modify.
