I must have a very special version iPad 2: mine simply refuses to install beta releases of iOS over the air. More specifically, it refuses to activate properly after the installation is complete.
My iPod Touch does this without a hitch: under Settings – General – Software Update I just click on “Update Now”, and after the installation I put in my password, and everything is as it should be, just like with a “standard” new iOS release installed over the air.
My trusty old iPad 2 however (64GB 3G Version) hangs on the activation screen for two minutes, and then gives me the message that it could not be activated. End of story.
What I then have to do is
- download the latest beta for my device from the iOS Dev Center manually
- shut down my iPad
- start up iTunes and make sure I have a USB cable attached to my computer
- while holding down the home button, insert the USB cable into my iPad (it’s called DFU Mode)
- iTunes will offer to restore my device
- select “restore” while holding down CMD (or ALT on PC I believe)
- a dialogue window lets me browse to that .ipsw file I’ve downloaded in step 1
This will work, however it will wipe my iPad and I need to restore it from an iCloud backup – which can take an hour or more depending on the amount of stuff I have installed.
My point is: it’s tedious, and clearly doesn’t have to be like this. I’ve read reports from other developers who are experiencing the same problem – mainly on 64GB iPad 2’s with 3G. Is it because those devices are no longer for sale? Have the activation servers been switched off for our devices?
