The .ofp may contain super firmware from multiple carriers, check the super_map.csv.txt outside .ofp first.

sudo apt install simg2img # If you have already installed, skip this step.
simg2img [super.0.xxxxxxxx.img] [super.1.xxxxxxxx.img] [super.1.xxxxxxxx.img] [filename to merge] # All split super imgs must be the same carrier
