So I just got my iPhone 6 replaced today, and I've taken it home and tried to restore from my back up that I did earlier, with the old phone. Said old phone was on iOS 8.3 Beta. I've tried (three times now) to install the beta on the new phone (iOS 8.1.2) and it's downloaded and "installed" the profile, to tell me to restart, which I've done, but Feedback Assistant is still nowhere to be seen, software update is still saying I am "up to date", however the profile is currently "running". I've also connected to iTunes, and tried restoring from my backup earlier, which I archived, and still nothing is happening. I also have an unarchived backup, which also isn't working. I need to get this phone up and running ASAP, can someone help please? Thanks in advance.
