This doesnt look good for you man. The reason you bricked the console is you didn't dehash before switching from rogero to ofw. You needed to toggle qa flag before switching to ofw. There are a couple ways to fix this problem, but both would require a hardware flasher which i am assuming you do not have.
You have a few choices. You can try and get the original bios dump from whoever you got the system from, but you still need to flash them to the system via hardware flasher. Or you can hook up a hardware flasher and see if you can still get a bios dump from it, and then patch them, which also requires a hardware flasher. Or you can send it to someone who does downgrading/ unbricking service and let them give it a go.
Most services wont charge you unless they can fix it, but it will cost you shipping both ways either way. Let me know how you want to proceed and I will see if i can help you out. Most importantly, DO NOT try and use bios from another console or you WILL have a permabrick on your hands. It would be nothing more than a parts unit if you do, as NO ONE on this earth would be able to fix it if you flash bios from another console.
