Nothing
Not even downgrade...
All exploits patched for now, you'll need to wait for a new hack.
I don't even think many people are working on it.
It WILL be hacked, It will just take a few months...
Just be patient and watch sites like this one, pspupdates.qj.net, psp3d.com, psp-hacks.com, psp-vault.com...
