Hi,
I am trying to restore my apple developer transition kit. I'm sticking to the DTK Release Notes. But when trying to repair or recover the .ipsw-file via Apple Configurator 2 I get the following error message:
Failed to restore device in recovery mode, libusbrestore error:21 [com.apple.MobileDevice.MobileRestore – 0x15 (21)]
Does anyone have an idea, how to handle this?
