You can use house of moto and where it asks if you want to delete user data you tell it yes. The only two methods to root a phone I have seen that seem to work on the .15 version of the firmware is Hydrogen Peroxide and kingoroot. There have been bricks with both and also loosing root on reboots. .15 patched the other exploits. There is not a way to unlock the bootloader with any exploit after the .15 update so if you are not unlocked before the update you are stuck. If you were unlocked you would never be with out root, once unlocked it is a snap to regain root.
