Hi! I ve replaced completly dead battery on a new one phone powered up and normally worked After using it couple of minutes phone has started rebooting. Going to apple logo then shuts down and again the same. I ve tried 3 different batteries I was also putting iphone into recovery and out of recovery. Still nothing. Is it possible that the U2 ic is damaged ?
I compared with working logic board and all the components are on place. What else can i check?
