Dell R720 (12th Gen *20 servers)

If you buy an R720 that the iDRAC is “bricked”, either by someone trying to do an upgrade from a really old version to the latest, or just the EMMC failing on update, you have a way to recover. You'll need to solder a header pin set on, and go direct console via UART, but from there you can either force a reset of iDRAC, or flash the EMMC if it is really bad.
