Hi,
I've started iOS 9 Beta 4 installation via OTA on top of iOS 9 Beta 3.
The installation started successfully and currently I can see the Apple logo and a progress bar below it. The progress bar is around 85% but it's been staying there for around an hour now.
I've tried plugging in the charger but there is no response (no sound/vibration/brightness change etc.)
Is this expected behaviour? Should I wait for another hour or should I (and how) intervene at this point?
Thanks!
If it's been stuck for an hour, it'll probably stay stuck. You could wait for another hour to give it every chance though.
To intervene, you'll need to hold the home and power buttons until the screen goes black.
You may then need to use iTunes to restore your iphone to iOS 9 Beta 4 (a lot of people do this as a matter of course because they consider OTA updates to be less reliable)
Hi Max108,
Thanks for the quick answer!
Does restoring my iPhone to iOS 9 Beta 4 via iTunes remove data (photos, videos, messages, applications etc.)?
Yes, the full process is to backup before updating and then restoring the backup afterwards. It's a bit more time consuming, but considered less error-prone by many.
Hi Max108,
I've force restarted my iPhone (https://support.apple.com/en-us/HT201559) as you mentioned.
Upon restart, it told me to "Slide to Upgrade". I've slided, entered my passcode and the iPhone continued to upgrade. It took rather short (around a minute or so) to complete and then voila! I'm on iOS 9 Beta 4 with all my data intact.
Thank you very much for your assistance.
Have a great day!
i Really need help!!!! My phone has this problem I've tried everything and nothing works I slide to upgrade and nothing happened. My wifi is pretty bad but it should work my phone is completely usesless I need help
What exactly happens when you "Slide to Upgrade"?
If I recall correctly -upon sliding- mine just asked for my passcode and then continued to upgrade.
I am not sure if it has anything to do with wi-fi at all. Maybe only after the completion to verify your credentials etc..
