I bought a PS4 from a buddy. Now I wanted to replace his bank accounts with mine (payments, passwords, etc.).
I deleted his Paypal from the PSN account and wanted to enter mine. PS4 itself does not work because there's always a bug, I know from my PS3 why I tried it via the app.
The app then led me to my PayPal website. Register, confirm payment etc. Everything done.
But I wasn't redirected to the psn app. Tried everything again but this time logged into PSN in the browser. Now it says my Paypal account is already given (which it is not because it is not displayed and I can't carry out transactions). What can I do / where is the error?
You can't use your friend's account, you need a new account with your address and your account details. It can't be overwritten, its data is still active
Your buddy has to deregister the PS from PP.
I removed Paypal as payment and he got an email that the transaction contract was ended.
