Shortly after Apple released iOS beta 6 of iOS 11.4 they revoked the developer profile so non-registered developers were unable to use the profile. Today 24 hours after releasing iOS 11.4 to the public Apple has released iOS 11.4.1 beta 1 to developers. For those who are now unable to install the beta profile there is a workaround, and at the end you will be able to get the new 2.2GB software update.

  1. Go to setting > date and time and change your date back (I set mine 2 months back)
  2. open safari and click here.
  3. Go to iOS 11 beta and choose your phone model click go
  4. Skip the Ad and then click allow
  5. Type in your passcode and install the profile
  6. Go to settings > General > Software update to register you have an update and hit download
  7. Whilst Downloading Go back to setting > date and time and change your date back to automatic
  8. Now go to back to settings > General > Software update and wait whilst your update installs and restart your device
  9. You now have the latest beta installed


Please Note during this process you may come across several error messages as your device date is older than app settings.
