I booted into option 1 eMMC bootx63.efi
that ended in “cannot open /boot/lua/loader.lua no such file or directory”
I assume, that the firmware upgrade somehow destroyed the boot partition or similar
any hints how to recover that?
I sorted it out.
A firware upgrade failed. I assume i was to impatient and unplugged the 6100 from power too early, instead of waiting.
This corrupted the boot partition and left it unresponsive.
Via TAC i received a new image promptly.
The “usb-stick-problem” was a slight confusion regarding my rack mount… note to myself: connect the box to external frontside usb ports facepalm
Installing pfsense from there on was straight forward.
I had a local backup.xml, so i was able to recover 80% of my settings.
