After Downgrade from IOS 9 beta to IOS 8.3 no Imessage and Facetime activation

Hey there,


i tested IOS 9 Beta 1 on my iPhone 5s. IMESSAGE and FACETIME could be activated without any problems.


No i did a downgrade to IOS 8.3 and have now the problem, that i stuck in IMESSAGE and FACETIME ACTIVATION.

If i install IOS 9 again, both could be activated.


I also did a clean install (DFU-Mode) and set as new device.


Please help ...

And now you know why downgrading isn't supported.

I would reinstall iOS 9 and wait for the GM.

There is only a problem with the iphone 5s which was on IOS 9.

Other Devices work properly with same Apple-ID.


Is there a possibility to delete this device ?


Does anybody know where the problem could be ?

What does an Apple ID have to do with this?
