I recently rooted and unlocked the Bootloader on my Galaxy Nexus — direct from Google — using this method. Upon doing so my phone reverted to the stock Jelly Bean ROM I had just after upgrading. All of my apps and settings were removed. I've downloaded and setup all my apps again, and I want to unroot my phone in order to properly use Google Wallet.
Will unrooting my phone with the Galaxy Nexus Toolkit wipe my phone and restore the stock Jelly Bean ROM?
