Chosen Solution
I recently got my iphone 7+ fixed. it had error 9 so i reballed the NAND and after doing so i put it back together after which it worked fine for a day or so.
Now it randomly shuts off and i dont know what to do, i replaced the battery, tried swapping housings nothing seemed to work. It again throws error 9 at me when i try to restore the device in itunes.
Help would be appreciated
Mostly on that cases that is the fault of Nand. You have to change other Nand and reprogram correct data and fix it.That issues i have faced many times and also solved by this way. Other point by remove Nand and restore via iTunes which error shows if still error 9 that means the fault of other site.If 4014 error shows that means the fault of Nand.
