PW2 Jailbroken PW2 Accidental Update to 5.9.4

Hi,

I had accidentally performed an OTA updated on a Jailbroken PW2 to 5.9.4. Is there a way to downgrade this / retain my jailbreak without having to perform a serial downgrade? (I'm very lazy to do electrical work atm and would like to list out my options before going to my last resort).

Thanks a lot
