Hi.. I have read many ways to change my carrier logo and I did it. I worked fine but today, I just want to go back to the original state so I copy and paste the backup SpringBoard that I've saved before. Then I restart my iphone and it stucks on the startup apple logo. I then copied the whole SpringBoard.app folder under the directory but still it stuck and freeze. Help me is there any way to go back? I don't want to format the whole phone. I have many stuffs in my phone that I have not backup yet.
