I am trying to resuscitate an EspressoBin that I purchased back in 2017. I bought it to make a Linux firewall, but the Ubuntu image apparently wasn't up to networking, and I was too busy to deal with attempting to make a custom Linux build to ensure that networking was enabled. I am specifically looking for help with the SATA Rescue procedure.
It seems that Armbian has created a Linux image with networking enabled, so I am trying to load the image. The Armbian instructions said to update the bootloader before attempting to use the new image. I (tried to) follow the instructions
