It has to be "cambié de opinión"
Cambié de idea.
Foxluv you are falling in the word for word trap when much of spanish is about phrases look up idea in our dictionary and the scroll down to the third set of phrases and you will find Cambiar de idea = to change one's mind.
Me arrepentí
Cambié mi chip.
First of all, "changed my mind" is an idiom, and it simply does not work in many languages, where -like in Spanish- it would mean that you have taken it out, and put a new one in. It gets even worse if you say "cabeza", because you'd be talking about a head replacement, as if you were a robot. If you think of it, when you use this expression you are talking about changing some specific opinion or plan you had in mind, not changing you entire mind.
In Spanish you have to be careful about "cambiar", because if you say "cambiar algo", it means that you replace it with something else. Thus, "Cambiar el tren" would not be "To change trains" the way you understand it, but to take a whole train out of the rails, and bring another one in its place. Here you have to say "Cambiar de tren". Same thing for clothes: "Voy a cambiar mi camiseta" does not mean "To change your T-shirt" in the usual sense, but to give your T-shirt away and get a different one instead. If you are just changing clothes within your wardrobe, you'd say "Voy a cambiar de camiseta".
Bottom line: avoid word by word translations, especially with IDIOMS!
It's cambiar de idea and cambiar de opinión, there may be more ways too.
to change one's mind (about something) -> cambiar de opinión (acerca de algo)
look up mente in the dictionary and you will see the above so I would say Tony is correct.
or.....look up opinión and you will find the following:
he cambiado de opinión -> I've changed my mind
