As the title says, I'm in the process of updating to 2.0 but am currently running 1.9. Should I flash my drive(it's a BenQ) back to stock and THEN flash to 2.0? If so, how do I flash it back to stock? And yes, I do have my original stock .bin. BTW, when I "read" my drive and save the bin, I see all zeros in the source DVD Key window.
