Update BIOS Failed

Attempted to update it to v3.06 and got this message:
“The BIOS image to be updated is invalid for Secure Flash or onboard BIOS does not support Secure Flash.”

I then tried the v3.07 exe via windows (as opposed to the LVFS firmware I already tried in my OP)

I appear to have the same problem a few people on the main BIOS update thread:

I checked my EFI parition. I partitioned it to 100MiB leaving 32 MiB for the BIOS update to use (which apparently is enough according to SodaStream: 11th Gen BIOS 3.07 + Windows 10 and (11 Alpha) driver bundle - #47 by SodaStream)

Since my NVMe simply has a fresh install of Arch, I will wipe it and install windows just to complete this BIOS update I need to use the motherboard as an SBC. Sucks.

I can’t be bothered to troubleshoot this further. Will report back if a windows install allows me to install the BIOS update.

UPDATE: Installing windows on my nvme ssd allowed me to flash the new BIOS firmware. Something about the firmware installer did not like my EFI partition that I had on my arch install.
