I have a 1.5 but im just interested to know (and I have a few friends with 2.6) about the new "Downgrader Test For PSP 2.50/2.60 Firmware." If you tried it, did it work for you? Also what were the "side effects" if any ("some unusual side effects being reported")... I can't wait to see what happens with it. I'm sure (I hope) this method will be cleaned up/streamlined and it will become the standard for 2.6's to be downgraded, especially knowing Dark_AleX and his amazingness. But for now, any of you with 2.6 PSPs, please post here and let us all know how this goes for you.
