On my Librem Mini, I reflashed the CoreBoot/Heads ROM from the file I downloaded from the puri.sm site (and made sure to pick the version for my Librem Mini V1), then re-signed the Boot files, then updated my Shared Secret. Now, when I Boot, I do get the flashing green light on my Librem Key (good), and I can open the OS Boot menu, and I can choose my installed PureOS to Boot. But then as soon as PureOS starts to Boot, my Librem Mini immediately shuts down.
Has anyone experienced this? Any ideas?
