It was actually from some v0.2.0 (whatever came with the nitropad). I did the update to the rom using the heads menus and a USB drive without a programmer. There was some friction in the heads menus regarding resetting the TPM after the flashing (the usual option did not work but if starting over and doing the TPM reset from the menu that alerts you about it it worked fine) but other than that it was doable.
I recommend doing it. The machine is noticeably faster, the fans actually come on as needed, etc. LLM inference 30-50% faster, no kidding. Do the upgrade to dasharo coreboot+heads v0.9.1!
