    Hi

    Error 9 usually occurs if there is a "block" somewhere stopping it from connecting with Apple's update server. The best bet is an external recovery.

    (1) Download a MacOS from the internet; (2) Make a USB drive bootable; (3) add the MacOS to the bootable USB drive; (4) boot the make using the bootable drive and recover from there.

    All data will the lost though.

    I hope this helps.

      OP is talking about T2 DFU recovery not Internet Recovery.

                  dead t2?

                  hows the esd diodes on data lines?

                  there is a reason it was in dfu mode - you do not try to restore until you check wth is causing it.

                    still connected to T2 but in recovery mode, not DFU mode...before it can connect with DFU mode but after error when revive than it became stuck in recovery mode in apple configurator
