Summary:
After updating from iOS 9.2.1 beta to iOS 9.3 beta, the system stuck at boot screen and can't enter the system.
Steps to Reproduce:
1. Open Safari and download iOS 9.3 Configuration Profile
2. The system required my iPad to restart after installing the configuration profile
3. Updating to iOS 9.3 in setting page after restart.
4. Boot screen was shown and can't enter the system. After a few minutes, the screen changed to blue and black then restart again. It loops again and again.
Here's my iPad's configuration: iPad Mini 2 / 32G Wifi Modal (A1489)
If that doesn't work and your iPad is still stuck in a boot-loop then you'll have to put it into DFU mode and restore it via iTunes. There are different methods for success with this, depending on exactly where in the boot process it's stuck, but Method 1 works in most cases:
Method 1)
- Attach the iPad to the pc
- Turn the iPad off
- Hold power and home together for *exactly* 10 seconds
- Release power but keep holding home until the computer beeps as a USB device is recognized (or until the restore starts).
- At no point should the display come on. Now your restore should work.
Having problems? Try adjusting the 10 seconds to be slightly less like 9 seconds, then 8, then 7. It’s a tricky timing but you will eventually get it.
Method 2)
- Hook up the iPad powered on to the computer with the iPad on
- Now hold home / power until the iPad turns off and keep holding for 10 seconds. If the iPad ever turns on during this phase,start over and hold for less time.
- Now release power and continue holding home until the computer recognizes the iPad.
Method 3)
- Attach the iPad to the pc
- Turn the iPad off
- Press and hold power. Keep holding power. As soon as you see display on the screen of any sort press and hold home.
- Hold power and home together for *exactly* 10 seconds
- Release power but keep holding home until the pc beeps as a USB device is recognized.
- At no point will the display come on.
