The Mythical Downgrader

Via Fanjita:
We've been hearing a lot of rumours and questions about downgraders recently. It seems that someone has been spreading a rumour that we have made a downgrader for v2.01+, but won't release it because we don't like downgraders. We'd like to just set the record straight, because it's getting annoying.
We would never hold back on an interesting hack for the PSP, without good reason. That's because, generally, we'd never work on something that we didn't think was safe to release - which is why we've never bothered to mess about with ISO loading.
We do have an unreleased downgrader for v2.0. The only reason it is unreleased is because there's no point - there are already perfectly functional downgraders for v2.0, that have been tested by tens of thousands of people, so what's the use of releasing something that's only been tested by one? In theory, that v2.0 downgrader would also work for v2.01 - in fact, it was originally written for 2.01, in the hope that we could use the GTA exploit to downgrade. But as we all know, the GTA exploit is no use for that, and so no v2.01+ downgrader is possible yet.
The only thing I can think of that might have fuelled these rumours is that we were experimenting with the v2.0 downgrader along with the UPDATE-mode discovery, but we found that that also does not have write access to flash0, so can't be used for a downgrader.
Also, some people seem to think that we're in some way opposed to downgraders, in the same way that we're opposed to ISO loaders. That's just not true - we believe that everyone has the right to upgrade and downgrade as they please (but at their own risk). If we found a way to downgrade, you can be sure that we'd share it.
Anyway, enough of the conspiracy rumours - please stop!
