How do I upgrade my Curve 9300 to OS 6 in 2018?

I'm still using a BlackBerry 9300 (Curve 3G) and I want to upgrade it to OS 6 from OS 5. But of course the BB service subscription doesn't work anymore, and neither do the official links for downloading BB software. Is there any other possible way of doing that in 2018?

These links still work: https://forums.crackberry.com/blackb...-spain-811355/

And for how to install, consult this guide.

Can you give the links for bold 9780 please.
