I know the CPU and NAND are married , so if your goal is data recovery you won ' t get it with a new chip . A reball is your closest option , but Apple ' s CPU chips are pretty much all super sensitive to heat , and probably the most difficult component to extractinstall . That ' s not to say it ' s impossible , I know it ' s been done by plenty of people , but most of the time CPUNAND is replaced , it ' s for illicit purposes , so it may be tough to find someone with experience doing that . Edit now that I think about it , data recovery should be your endgame with this device . Even if you get it up and running , oxidation is going to make sure it doesn ' t stay that way . It could come on for a few hours , weeks , maybe months , but it ' s best to get a new phone that won ' t randomly crap out rather than have your family member use it until they ' re lost in a sketchy neighborhood and need it for GPS and then have it die .
