Incorrect Apple ID after Software Update to iOS9.3

I also have this problem. I did the same as you, changed my password to see if that would help, then I was told I wasn't using the correct apple ID.

Hello i have this problem also on my ipad can anyone help rang apple support bit could npt help me

i spend over a hour between online support and on my regular home phone, the tech on the phone is telling me i have some other apple ID , I've never had this problem till last night, can't activate using that ID,so I'm locked out, she sent a reset request that takes 24 hours, seems to a problem on their end, but she acknowledged their is a issue, very vague at best

Hi I also done a software update on my ipad but was told it must be the original account and password but i dont have this as o changed my apple od and password also any luck on your problem

won't know till tomorrow, - this "mystery" apple ID that she couldn't tell me, - seems like they can't tell you that they caused this to happen, but I've bought the phone new 3 years ago and never had any issue with my apple ID, and never changed it, I'll know more tomorrow,seems to be related to the "find my iphone App' - she wasn't telling me much

Theytold me o must have my original i cloud account which i used to set up ipad when first bought but i cant remember it as they always telling us to change it so no help what so ever

Hello Community,

I updated my iPhone 5S this morning (since I was curious about the new version iOS9.3) and wanted to activate my phone after that, however, I always receive the message 'Incorrect Apple ID - ..... cannot be used to unlock this iPhone.'. I'm really sure that my Apple ID and my password are correct, I actually changed my password to rule out this option, so has anybody an idea of what could have gone wrong and what I can do about that? Thanks!

Best, Thomas

Did you buy the phone from apple or did you buy from a third party? If it was the third party then you may have hit activation lock. It may be locked to someone else's ID. You would need to contact the seller that you bought it from to get them to turn it off. If not then there is nothing apple can do.

If you bought it from apple then you should be able to reset your phone. You will have to use the apple ID that you used to activate it the first time. If you changed your apple ID then you still need to use the original one to activate it.

When it asks for your password for activation what is the email it is asking for? It usually will show the first and last character of the email with asterisks in the middle to mask it out.

Greetings iPhone5SThomas,

Thanks for using the Apple Support Communities!

I understand that after updating your iPhone to iOS 9.3, your current Apple ID and password are not working to activate your device. In some cases, the hint that you see on the Activate iPhone screen may not match your current Apple ID.

i updated to ios 9.3 this morning too. i'm beginning to wish i hadn't.

I've had exactly the same problems as you. i'm locked out of my phone and my apple id can not be used to unlock my phone apparently!!!!!!!!!

my apple id email and password are 100% correct

i tried to do a forced update on itunes but that didn't work so i've restored my phone to factory settings and lost all my contacts, photos etc

and guess what ????????? its still saying exactly the same GUTTED

definitely an Apple issue
