I have an iPhone 6s. I was at iOS 10.1 beta 2. The iPhone downloaded developer beta 3 overnight so this morning I told it to install now my iPhone is a constant loop trying to actually install.
I saw the apple and the start of a progress bar then it stopped and restarted the install. Now it just keeps trying to start.
I see the Apple, the Apple goes away and the screen goes black and then the process just starts again.
How do I get it out of this loop so I can restore my iPhone?
Holding power button has no effect.
Holding power & home at the same time has no effect.
