Root [Sprint/Cricket] Unroot directly from device....

[McCartney62]

Is there anyway to unroot my device without my laptop. I want to return my phone to Sprint because it keeps messing up USB cables, I'm going through those like water! Also my laptop doesn't wanna recognize my s3 so that leaves out the Odin method I'm accustomed to. Any clues? Please!!

Since you are rooted I assume that you have a custom recovery. Go into recovery and wipe cache, dalvik, data, system, and flash this.

This stuff is sooo confusing....

It's not that confusing once you get into it. What are you having trouble with?

Putting it back to stock..

There's a zip you can flash in recovery that'll completely return you to stock without wiping anything. I've used it a few times


Edit
Actually that's it up above.

You shouldn't need to wipe anything, just flash that file

Make sure to reset the counter also.

The file in the link I posted resets the counter automatically.
