Siglent SDS804X HD still 'hackable' to SDS814X HD?

Been looking for a scope lately to get a little more in depth with troubleshooting, and it seems that the 70Mhz version is identical to the 100Mhz version, minus a software unlock?

I've seen the unlock guides and keygens, but has that been patched out of newest models? There was some chatter it had been...

Thanks!
