HEADS UP, installing iOS 17 beta 2 over iOS 16.6 beta 3 bricked my device. I installed the second beta over beta 3 of iOS 16.6 on my iPhone 14 Pro Max, and things were working ok for awhile—although when I tried to install the beta for my Watch Ultra it hung during the download process, saying that it was paused until I connected to Wi-Fi, and I was already connected to Wi-Fi. So in order to get my watch working with my phone, I tried a hard reset of my phone, using the usual volume up, volume down and long press on the right button.
When it rebooted, the phone’s screen was unresponsive. Completely unresponsive. The buttons worked, but I couldn’t swipe up to unlock the phone. I tried resetting three timed with no success.
I ended up having to attempt to recover the phone by connecting it to my iMac, which prompted me that it had to download 9gb of software to proceed with the recovery. The recovery failed, and it ended up erasing and reflashing my phone with iOS 16.5.1, the latest stable release.
So in order to recover from my backup, I had to set up the phone as new, install the 16.6 beta 3 firmware again, and recover from my latest backup, which took eight hours to finish. I’m back to where I started again, after setting up my wallet, Face ID, and the other required settings. This was a disaster mitigated only by the recovery of some memory that had been filled with who knows how many caches that had accumulated over time since innumerable dirty firmware installs in the past.
Since I had also installed 17 versions to my iPad Pro, HomePods and Apple TVs, those devices now don’t show up in my HomeKit on my phone running iOS 16.6, and I can only access them via my iPad. And for some reason my HomeKit shows a “Default Room not responding” error, despite my not having a default room. I’ll have to wait for later, more stable releases of the 17 firmwares to resolve all of these issues.
I encourage anyone considering installing the iOS 17 betas to proceed with caution, and I definitely wouldn’t try to install it over the 16.6 betas. And don’t expect your peripherals to play nicely—iOS 16 can’t recognize HomePods or Apple TVs properly when they’re added to your system from the 17 betas, and as expected, these early developer betas definitely have a long way to go.
