Hacking Advice for Installing cfw on 3.50

[Dopam1ne]

I have an old UK Vita 1000 running ofw 3.50, looking to install cfw. I have been following this guide: https://vita.hacks.guide/updating-to-3.65.html but the dns server seems to be down.
Any advice or links to solid relevant guides would be greatly appreciated, thanks in advance

Any ideas? installed qcma and got the ofw 3.65 pup + europe xml files but it doesn't seem to want to install, error (c3-10698-4)
Do I need a higher fw version or something to go from 3.50 to 3.65?
