Honestly,
They need to be more clear at how they word that then, as the way they make
it sound is, you literally! cannot downgrade, period. Once it's on I O S 9,
that's it. No turning back, regardless.

Chris,
You are correct. You can go back. What Apple means, however, is that if you
decide to downgrade, you have to erase your phone and start over from
scratch. "From scratch", yes, but of course you can restore from a backup.
The thing is, your backup will still mean you have to do some setup again.
Notably, Touch ID, and reauthorizing your cards for Applepay and other
things like that.
So, they're right. You can't go back, at least, not in the same way you can
go forward. You can always go forward and retain your authorizations and
what not. You can't go back and retain those things.

Guys,
I just wanted to clear up some miscommunication by Apple. They say on the
developer web site that once you upgrade to I O S 9, you cannot go back to
a previous version, like 8.3. That's utter bullshit from what so far I
can see. Now, I wanna make this very very clear. I am saying this on the
basis of! from what I so? far! can see! Keep that in mind.
I have an I O S device which I did update to I O S 9. I've changed my
mind, and now am deciding not to deploy it to I O S 9 after all. OK, I
have a device I will! be keeping on I O S 9, just not this particular one.
Anyway, the point is, they are only partially right in what they're saying
on their web site from what it seems.
1. If you try to downgrade while your device is normally booted up into I
O S 9, then no. It won't work. That is factually accurate information
which I have verified.
2. If, however Apple has not stopped digitally signing the previous
version of I O S, which of corse, 8.3, they haven't, then you can get it
back as long as before you restore the device, you first get the device
into DFU mode, just as you did when you upgraded to I O S 9. I tried
this, and I O S 8.3 definitely now is downloading. I'll keep you all
posted, and let you all know if I'm able to flash it back, and restore
from my backup. To the best of my knowledge though, this seems to so far
be working.
Chris.
