For my question, let me give some background. My business is to data clear phones and tablets. I've been tasked with research into rooted devices. I have a very basic grasp of this concept. I think what I've found is that rooted devices can be 'unrooted' but only if one knows what rooted it originally. I've found this:

You’ll have to use either a terminal emulator or ADB. Here are the commands to uninstall it:

mount -o remount,rw /system rm /system/app/Superuser.apk

Would that be a good way to remove the root from all cells across the board?

Specifically what I need to know is what do rooted devices mean to the cell phone data clear industry? Is there user data in a rooted device after data clearing it manually?

Please edit your question and write a more meaningful title. See also meta.android.stackexchange.com/a/1182/440 I guess one approach would be to flash the stock ROM followed by a factory reset. –  Flow Jan 7 '13 at 19:41

Since a device is "rooted" (generic Android device, no names of manufacturers, this is just a guideline, mileage will vary), chances are:

  • boot-loader is unlocked
  • custom recovery is installed

The above two usually go hand-in-hand together, along with running a perhaps, custom ROM.

If the above criteria is held true for that said device, then its a matter of issuing a fast-boot to format all partitions individually as in using fastboot erase xxxxx where xxxxx is one of:

  • boot
  • recovery
  • data
  • system

That, may fit the criteria to the vague representation of data clearing industry, or some standard that was stipulated and to be carried out as per the OP's question.

Samsung phones don't have fastboot remember, or a bootloader for that matter. –  Liam W Jan 7 '13 at 19:52
    
Who says Samsung.... OP never mentioned a thing about it!!! –  t0mm13b Jan 7 '13 at 19:54
    
They were being general, so make sure you cover all the corners ;) –  Liam W Jan 7 '13 at 19:56
    
I realize my question was not the best. I am really trying to understand this topic by deadline time and realizing I need way more time. My supervisor is leaning towards the belief that these cells are data cleared. But with root access on them, I disagree and I need to be certain. Thank you all for your input. –  Angela L Jan 7 '13 at 21:18
