The full debrick.sh script with the DESTROY command cares not what size HDD you have, it wipes the partitions, rebuilds them, sets up the MDADM array and writes the extracted rootfs.img to it. My fiddling MBL was originally a 1TB, its been a 640GB,1,2,3,4,6 & 8TB with that script.
It will also happily write your MBL with the latest/last firmware so there’s one step that’s not needed.
