Well, 515 users don't have a reversion path like 513 or 2160A users have. Only prior FW available to us (w/o Funai intervention) is 727H, which would make a 515 operate like a 513.
If you install then don't like what SuperFW 727V does for you, you *might* be stuck w/a 513, but it would be "exciting" and informative.
HOWEVER, I'm pretty sure all known 515 upgraders have been OK with it.
Option is to use your SKIP program cautiously?
