Experimental Downgrader for 2.5 and 2.6 PSPs emerges
First of all let me make this very clear. If you try to run this Experimental Downgrader it will brick your PSP, so be a bit more patient while the developers solve the final bugs. Did I say it will brick your PSP already?
Dark_AleX made not too long ago an experimental downgrader which theoretically should work but at the moment isn’t, due to some bugs in the programming and some other things that are mostly incomplete.
In my opinion, since we discovered a way to access the Kernel mode on these quite recent firmwares we should be making new homebrew software for it instead of going back to 1.5. But stay tuned PSP owners, because very soon we might have a working downgrader in our hands. Let’s just hope they don’t pull a WAB/Yoshihiro on us again.
