Many of us have know that the newest update that was push 2.0.5 break root. Well, for those who didn't know, now you know. Let's me be clear, there is NOTHING TO BLOCK THE OTA UPDATE, unless you build your own firewall. That said, the mod that we had was to use sql and turn automatic OTA into manual thus unless you were looking for it, it shouldn't. Or something you did may accidentally turn it back to automatic.
That said, we had one report of successful revert back to the older firmware here from 2.0.5. I have made a suggestion to manually force the system to fail the boot 8 times and do a full wipe. And this should revert it back to the original firmware that came with the Nook HD/HD+. Well, in the future, this may no longer be the case, as newer Nook may come with 2.0.5 out of the box, but let's do this one step at a time, we aren't there yet and maybe better solution will come later. So, if you accidentally updated to 2.0.5, you should try the following.

So, if you accidentally updated to 2.0.5, you should try the following.
- Backup your naughty stuff that's on the internal storage (even if they are not naughty, do it so anyway)
- Force the nook to fail at least 8 times. First you power the device off then hit the power button, and when it's trying to boot, hold on to the power button, and I think about 10sec after it will force poweroff. You timing have to be quite good and make sure it's not getting a success boot. You basically have to do that at least 8 times.
- If you successfully did all that, it should revert back to the original firmware. I know that the 8 boot loop will reset it back to 2.0.0 from 2.0.2 because I did that before.
- Try rooting it again.
