I'm new to android and I have a doubt. I've been searching for an answer but can't seem to get clear info about it from the web, so I'm asking here in hopes someone can help me out.

I want to copy my /system folder to my PC so I can hand it out to someone else who needs it to "unbrick" it's phone. I know I can do it with an ADB command and it sounds pretty simple. However, I'm afraid that some of my user info (accounts, contacts, wi-fi passwords, messages, etc) may also be passed along, and that's something I don't want.

So, is there any personal info stored in the /system folder or can I safely make a copy to help someone out? And if there is personal info, how to avoid copying it while copying the /system folder? My android version is 4.0.4.

Thanks a lot.
