Direct Thunderbolt connection, forcing true DFU mode, and executing an in-place software update or Configurator revive.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Never select ‘Restore’ if data is unbacked-up; always select Update.
  2. Use an authentic Apple USB-C 60W/240W cable connected directly to Mac ports (no hubs).
  3. Enter true black-screen DFU mode and execute an Apple Configurator Revive Device pass.

Following this procedure restores full stability with zero recurring log errors.
