Whenever I try to install the iOS 12 Beta, it downloads the update but it never installs it. When I try to install it, I get a message saying "Unable to Install Update. An error occurred installing iOS 12 Public beta." I've tried redownloading the update and restarting my phone but it doesn't seem to work. I have an iPhone 6S currently running iOS 11.4 (15F79).
iPhone not installing iOS 12 Beta
I've been having the same problem with an iPad Air - also running iOS 11.4.
I am having the same problem, and have not been able to update since beta 6. Help! Any solutions?
My phone was stuck on a previous beta and would not update - the only fix that worked for me was to reset my network settings: General - Reset - Reset Network Settings My phone is currently downloading the most recent beta
