My tbolt is currently rooted and I'm gonna be selling it to a friend in a couple weeks. I was wondering if I can wipe all the data from the phone with the root and for there to be no way to recover my data (since I backed it up when I rooted) or is that only possible if i go back to stock and wipe data then? basically I just want to make sure that when I hand over the phone there is no way for them to recover any info of mine. thanks.
