Unroot Bionic Research-Correct Method

[radams]

I am in the process of learning and have rooted my Bionic.I have used it as a practice device,so when I get my new Note 2 I can root that also,and hopefully not brick it.The Bionic was successfully rooted using Razrs Edge and information from this site.Thanks. I installed and uninstalled Safestrap without flashing any ROMS except my stock ROM that I rebooted with once. The Bionic is now sold and I need to unroot. I have searched all morning and cannot find any methods to unroot having used Razrs Edge to root .I have read about Pete's Moto tools but that seems like it is for earlier root methods. I am using ICS 6.7.2. and root has been checked with Root Checker and Titanium. Thanks for any help or advice.

If you fxz 246 that will break root.
