iOS 14 Unable to Activate after restore

Last night I restored my iPhone 11 Pro Max to iOS 14 beta. After iPhone restored I am stuck at the activation screen.

In setup assistant after selecting country and signing into my WiFi my iPhone tries to activate. After a few seconds I get:
"Unable to Activate

Your iPhone could not be activated because the activation server cannot be reached. Try connecting you iPhone to a Mac or a PC with iTunes to activate, or try again in a couple of minutes.

If this problem persists, contact Apple Support at apple.com/support"
  • Restored on a MacBook 12" running macOS Big Sur beta 2

  • Shutdown iPhone on setup assistant screen and restarted.

  • Used multiple good Wi-Fi connections.

  • Also tried activating on Cellular.

  • Tried removing sim card and reinserted.

  • Tried a different sim card from the same carrier.

  • Re-downloaded iOS 14 IPSW file.

  • Put iPhone back into recovery mode.

  • Opened finder selected iPhone, held down option while clicking on restore.

  • Selected iOS 14 IPSW file.

  • iPhone restored.

  • Get the same activation error.

  • Put iPhone into recovery mode.

  • Opened finder, this time I selected restore without holding option.

  • iPhone restored back to iOS 13.

  • Also tried activating through finder and I get the following error: "Activation Failed The iPhone cannot be synced. Received an unexpected response from the device."

  • Still receive "Unable to Activate".

It's almost 24 hours and I am still unable to activate my phone. Anyone else having issues?

Hi! I have the same issue at the moment have you figured out how to fix this?
Same issue here. Anyone have a solution?

SAME PROBLEM
Yes I am having the same issue as well. I have also updated my MacBook to Big Sur beta, downloaded the iOS 14 ispw file and attempted a restore with no luck. Still have the activation lock. Did you find anything out?
