For every phone that i mod there are always tricks to set it back to stock. today that is just what i had to do, and i learned a lot from it. Remember that smart phones are more computers than they are phones and if your speaker goes out or you charging port goes bad, or what ever issues you have u can back up all your apps, all your contacts, your text messages and ring tones. Even for a phone that has never been moded, don't worry about asking my for help.
i don't have to mod your phone to teach everything you need to know about it.
The basic lesson from this post is never give a moded phone back to your phone carrier, let me set it back to stock and they will never know.
