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.
