My iPhone 6 stopped functioning and constantly show a picture of cable to be connected to computer. I connected to my McBook Pro and tried to retstore but it failed to extract information from Apple. I updates my Mac to macOS Sierra Version 10.12.6. For the first time it went through the extraction process and finally stated loading picture and then gave an error " the iPhone "iPhone" could not be updated. An unknown error occurred (2006). Pl suggest how to resolve this problem
