Seas0npass JB of an older ATV2 OS

Hey guys this seems like a really stupid question from a seasoned JB-er but…

 

I have an ATV2 on 4.3, I don’t have the SHSH but the thing is working on 4.3.

Does i need the SHSH just to JB it? I’m not sure if seas0npass needs the shsh if i’m already running the older firmware. 

If it does. Anyone know how to JB an tav already running 4.3 without SHSH?
Cheers for the help.

 

You can use Seas0nPass to install older firmware versions, but unfortunately doing this will require saved firmware signatures for the version you wish to use.

If you’re using aTV Flash (black) you may in fact have some of these signatures. Full details on this process can be found here.
