Hi everyone,

I'm trying to install the beta onto my device (iPhone 7) without a developer account (I know, I know...), however once I select the IPSW profile, and after waiting a while, I get an error saying that the iPhone could not be updated because an unknown error occured (error 14). Does anyone know how I can solve this problem?

I've searched online and found the most common causes of error 14:

  • USB cable failing or problems
  • Using an old version of iTunes
  • Firmware errors or corruption
  • Low storage or memory on your device
  • Unstable network connections

My USB cable is working fine, I'm using the newest version of iTunes, I have a very stable network connection and i have enough storage on my device. Does this mean that the firmware file I'm using is corrupt? I got it from betaprofiles.com

Thanks.
