Where has this development been going on? Just so I can read up on the discussion here..
Why wouldn't it _obviously_ be possible to back-grade to original firmware? That's a 100% prerequisite for my part - a proper process for moving back and forth between the hacked and the original firmwares. And obviously, if any new upgrade comes along, I'd want to upgrade to that.
I can see a reason for this not being possible: the firmware only wants to _upgrade_ versions, and the way to get the hacked firmware into place would be to state that it was a higher version. However, in the hacked version, couldn't one simply find that one specific check for which version was on the firmware on the card, and remove it?
