Hmmm.. Im having the same problem except my dilemma is a little different... I so replaced the screen on my Iphone 6 plus i mean the whole screen... The screen i ordered already had all the replacement parts installed on it so all i had to do was literally slap it on and call it a day but...... Im having the issue of it saying Touch ID is unable to active.... confused!!!! I tried all of the suggestions in the above comments and still nothing!!!! Help!!!
