If the 000000 code doesn't work (you can test it right now, it won't change anything) then you need to find its SPC/MSL code, which can be found on your pc with some utilities, I personally used SE47 for mine, it can find it, or reset it to 000000 for you. Just dial the ##778, or if it doesn't go straight to the menu, ##778# (thats sprint, I think) from the Phone app, it will open that 3 choice menu, click on Edit, enter the 000000 code, remember to use the alt button to use the number 0 on "p", so enter alt p alt p alt p until you get 6 0s. If it says wrong code, try it again double checking you are putting in 0 and didnt miss an alt some place, or if it does work and goes into the edit menu, click cancel and exit out, then take it to the store, or call them, and get the info to program into it from that menu.
