Apple ID Password doesn't work after typed in
I just signed in a phone erased to factory setting (I phone 5S). Then I restore my back up from I-tune to this phone (5s) with my backup of another phone (I phone 4).
Now both phones require me to sign in with Apple ID password. I phone 4 I tried to turn off the "Find My iphone" and iPhone 5s I want to sign in the password but both did not work. I have trying many times, like the ways with hardware reset, internet connection reset. But they don't work at all. Any ways to fix the glitch? Thanks in advance!
