Yes if last_id.bin is still present/been re-created following a successful or failed attempt then the media card isn't read further. Therefore you should check for it and remove it if it's there each time, even if exactly the same commands are re-attempted, in case it is there. If update.log is added or updated (even if any commands have result in errors reported) then last_id.bin will be there.

It's mildly interesting that it didn't process the 'reboot' command at all but very disappointing that the 3 ergn commands failed with error, i was hoping that at least 41 would erase.

You can keep trying but i think it's almost certain now that there's physical flash damage present. No software method can repair that unfortunately.

PS: I'll move this discussion to a separate thread once i've seen you've read this post (EDIT: Posts moved from [Only registered and activated users can see links. ]).
