Stuck in Activation Lock loop
Hi guys,
My girlfriend used an iphone 6S for quite some time and when she decided to upgrade it, she appears to have reset her device without logging out of her icloud (as explained by her to the best of her abilities).
Long story short, the phone is stuck in Activation lock saying that the device is linked to an apple ID but when I enter it it says it is incorrect. There was never another apple ID associated with the device so I am for sure entering the correct credentials, as I am able to login to find my iphone, for instance with the same apple ID and password. The device cannot be seen in find my iphone under devices associated with this apple ID. Tried a few DYI repairs as seen on youtube but nothing seems to work. Can't connect to itunes for a factory reset as well.
Any help would be appreciated. Photo of the activation lock is attached (sorry about the busted screen protector).
Thanks.
iPhone 6s
