When running the firmware utility script (Install/update UEFI (Full ROM) Firmware) as detailed on the mrchromebox site, I end up with the following error.

Downloading Full ROM firmware (coreboot_edk2-lava-mrchromebox_20240908.rom)

Firmware download checksum fail; download corrupted, cannot flash.

I have tried adding the -k flag when downloading the firmware utility, but still no luck.

the file exists on the server and has the correct checksum, the download simply failed for one reason or another and the script prevented you from flashing a bad file

I have tried the download multiple times, across multiple days, still the same result. Is there anything you can suggest I try? Thanks

the downloaded file and checksum end up in /tmp. check the file size, compare the checksum manually, etc
