, yeah i had similar issue but that was my mistake. I had dual boot up and running fine but once i mixed up HDD and FW so like had OFW and CFW HDD in and then it YLOD on me, stupid
So anyway CFW was still working but when I tried to run OFW it didnt even bother to read HDD just got RSOD(red screen of u know what).
I knew it wasnt HW fault as CFW was still going so I followed this:
And it was fixed later I got same thing on CFW but fixed it pretty much same way but I maybe used NOR dump from
It fixes up few flags I recon so it may be essential step before u load you own NOR backup.
Anyway its all good so try this out and be patient thats all u need
Good luck !
