(adsbygoogle = window.adsbygoogle || []).push({}); I can add funds with sp-int but playstation store on this server not available.
I think thats only in prod-qa but I can't create this cause psn will say that the creditcard details are wrong.

yep. Theres a PSID Changer.
It can also change the Console ID if you can find someone elses.

i hope this is not the only way to fix it. i have a ylod ps3. can i take this hardware id? and where can i find it?

i will try it first with ftp

what would happen when i try to use a random hardware id?
will sony recognize it?

Random Console ID's dont work. They have to exist.
Random PSID's work.
