wrong section but you could do it in the storage settings it should say "factory reset"
If you didn't mean that look up your phone and try to find a .nbh that corresponds to your phone.
Then boot into fastboot mode and take care of business.
That should rewrite everything and could possibly cause a brick so if you do brick your phone, its not my fault.
Triple check and make sure you have the correct files before flashing (if you have to)
This forum is for the T-Mobile Dream / Rogers
EDIT: I am not to sure if the Moto Cliq even has .nbh files to flash.
