This is my first time attempting to use OpenWrt, but I'm familiar with flashing images with dd.
GRUB works fine, but selecting either OpenWrt or the failsafe option, I get XZ-compressed data is corrupt; the following is the error output in verbatim:

As I mentioned earlier, this is the first time I'm trying out OpenWrt. I'm guessing it might be possibly due to this specific version of the image, so I'll go ahead and try them. Please reply if there anything else I might try.
For context, this is not the UEFI image; I'm trying to either make OpenWrt run either bare metal on a laptop or within systemd-nspawn container (which can run raw image that I used to flash drives for bare metal). As a side note, the systemd-nspawn route also have failed. As for bare metal, I've tried on two separate laptop with the same image flashed on a USB stick with same results.
