Yes, No bluray in hybrid, I think there is no more risk of losing it completly than if you was to install 2.36 debug. Anyway think that problem is nearly sorted now by the team working on the DRL tools, Hopefully! I have lost it on one of my other consoles but not to bothered to fix it yet.
i'm sure it will be sorted easily and permanantly soon if its not already. I'm still mad to get unmatched drive boards working too, this is a problem for lots of people, I hope someone sorts it soon.
