I can't upgrade to iOS 9.2.4

I currently have 9.1 on a 6S+. I tried going through the usual upgrade process in iTunes and I got

This device isn‘t eligible for the requested build‘


I went through the proposed solutions at https://support.apple.com/en-us/HT201442

but nothing worked.


I've never had this problem before. I just checked the status of my certs, and they look fine. OS 10.11.4 and the latest Xcode seemed to have installed fine.


I've used the same Macbook Pro for dev for about 1 1/2 years, so I don't see this being an issue of my gear.


Any suggestions appreciated, but I could use specific and detailed instructions i.e. which UI to make changes in, specific drop-down menus, et al.

This is the only Apple link I can find:


https://developer.apple.com/ios/download/

Can you share the link you used? I can't seem to locate one that allows me to change the URL to beta 3.


Thanks.

Download beta 4 - (copy the download link that begins - browser dependent (i used safari)) > replace the file and folder path in the link to beta 3 > replace the build number to 13C71. it worked for me to download beta3 which allowed me to restore via iTunes. then an OTA update to beta 4 worked
