iPhone 5 won't turn on after replacing battery

The whole replacement process is a fairly simple yet delicate process. What makes delicate is because of the ribbon cables. These cables are truly sensitive. An easy bend could potentially damage the cable.

Some people think that lifting the phone screen at a 90-degree angle while working on replacing the battery is easier but this will potentially stretch or bend the ribbon cables. It is advised to remove the screen when working on the battery.

OP mentioned that iTunes detects the device. This definitely means that the device is working, just the screen is faulty. As what others have mentioned, you need to either reconnect these cables or replace the whole screen entirely.

[doublepost=1538400804][/doublepost]I had this problem after I replaced the battery. It was fine at first then I dropped the phone on the carpet. Not a particularly hard knock but the IPhone went into this white apple of death. I connected to iTunes and sure enough my problem was exactly the same as yours. Showed the iPhone serial number and said it had a problem and needed to be restored. Restore failed. Several times. I gave up on it. Bought another used iPhone 5s in perfect working order except it had a weak battery and cracked screen. No problem I thought. I will swap the new screen and battery from my dead iPhone. Guess what? After I did that the newer one did the same exact thing.i could not figure out where I went wrong. I bought more new batteries. Tried swapping the screens back around and nothing.
As I continued to mess around I stumbled on the fix and this was the only thing I got to work on both IPhones and they are both up and running. Bad news is the data is gone as it involved restoring them without the screen or home button plugged in. Yup. That's the trick. Restore the IPhone with no screen or home button. You will not be able to finish setting it up with no screen or turn off device. For that I unplugged the battery. Then replaced the screen.

I think what caused this was a damaged pin on the first ribbon cable you connect when installing the screen. I found minor damage on this. I think in shorting the connector it somehow corrupted the screen driver causing a fault in the boot up. Anyways I hope this helps someone else. It may even involve buying a new screen after you get the boot up sorted.
