I have a Android Samsung Galaxy S Captivate SGH-I896 and I have some problems with the sound. My provider sent me a new one and expect the old one back in it's original state.
So I have one that is rooted and unlocked and a clean one.
Can someone help me unroot it knowing I already did a factory reset on it.
I'm trying to root it again (thinking the unroot will work) and I'm trying the same way I did it the first time but it doesn't work.
Is it possible to format the old one with some image made from the new one?
