I have been using your firmware for years on my ASUS Chromebox CN60 M004U ( panther ) running archlinux from the very first day but today when I tried to update full uefi rom 2405 release to the latest with the script it failed to update then I foolishly rebooted. Now it powers up but no bios splash screen, nothing. I did read the docs but it is not clear how to proceed with unbricking. Firstly I would try performing an EC reset as the docs suggests, but my panther has no reset button so I need help how to recover my chromebox bios firmware. I have frequently updated full uefi firmware during the past few years with no issue, so it is quite strange why it failed now...

PANTHER doesn't have an EC. If the firmware update failed and you rebooted, then you're bricked and need to unbrick using a ch341a USB programmer as per my unbricking guide: https://docs.mrchromebox.tech/docs/support/unbricking/unbrick-ch341a.html

if you rebooted rather than saving the log so I could examine it, there's no way of knowing why it failed.
