    So i think everybody knows that you can sign homebrew on the psp.
    But what about a downgrader is that possible [​IMG]

    Netherlands, currently
    What do you mean, a downgrader?
    6.20 tn-b can run older PSP updates, and Hellcat's Recovery Flasher can flash any sort of firmware, but neither of those are downgraders.

    it's semi possible.
    but first someone would have to build a reliable downgrader, with a built-in kernel exploit to gain kernel access(which unlike with a HEN isn't granted with current signing methods!)

    The problem is not the downgrading program being signed... I mean we can run them through HEN and such.

    The problem is a lot more complex.
