Not that I'm aware of. Maybe be you just need to start from scratch. Backup your iPhone via iTunes and/or iCloud. Afterwards, go to Settings - General - Reset and then select 'Reset All Settings'. When complete, reboot your router and modem. After that, try updating to iOS 9. If it still fails, delete the profile and then re-download a new copy of it, then try again. Follow the prep and installation instructions to the letter via the following link.
