Attempts to install the iPadOS 16 beta all fail on my “iPad Pro (11-Inch)” (FTXN2C/A), with about 20 GB free storage.

Methods I've tried:

Over the air, after installing the profile from Apple Developer web site. Result: the 5.6 GB image downloads; "verifying update"; device reboots; progress bar briefly shows a sliver of progress for half a minute or so; device reboots again; presents the regular 15.5 lock screen, and behaves as though I'd never dowloaded the update at all.
Connected by USB, via Finder, option-clicking "Check for Updates" and choosing the .ipsw image. Result: “A software update is required to update your iPad”, followed by “Can’t install the software because it is not currently available from the Software Update server”.
Connected by USB, via Apple Configurator. Result: ““The operation couldn’t be completed. (AMRestoreErrorDomain error 10 - Failed to handle message type StatusMsg (Protocol error)) [AMRestoreErrorDomain – 0xA (10)]”; iPad is bricked; forced to reinstall a fresh 15.5 image and restore from backup.

For what it's worth, for the past few years no beta version of iPadOS has installed properly over the air (although the RC versions do, and tethered .ipsw-based installations have also worked).

Anybody clue me in here?

thanks,

Same here on my iPad Pro 12.9 3rd Gen MTEL2B/A.

Installing from the profile pops the 'I need to uninstall some stuff' message and then hangs.

Installing via Finder and the downloaded OS fails so I'm assuming that the image for my particular iPad is not available just yet, even though it is listed as supported for iPadOS 16. Or possibly although perhaps unlikely that it can only be installed from macOS Ventura which I am not running yet.

I erred in the title of this post; it's actually an A12X, but it appears that they share the same .ipsw image. The model (as per the back shell) is A1980.

I tried again via both Finder and Configurator, to no avail (ensuring to try a full restore rather than an upgrade). No dice. Bricked, and had to reinstall 15.5 again.

It seems that this iPad model is unsupported, despite the documentation.

The only solution I have found is to install the most recent Xcode bets (14 b3 at the time of this writing.) That includes the driver that finder was trying to install. You can use Finder to install iOS 16 beta ipsw. It worked on my M1 Max MacBook Pro and 5th gen iPad Pro 12.9.

Thanks for that suggestion @DaddyWarbucks. I never got around to trying it again in conjunction with the Xcode beta, but I am happy to report that the over-the-air install finally worked this week with beta 5.

Maybe they fixed something in the bootstrapping. Of course, the release notes make no mention of it, nor has there been any comment whatsoever on my ticket filed in June (FB10421553). 🤷🏼‍♂️
