(adsbygoogle = window.adsbygoogle || []).push({}); Got a little problem. I had to restore default settings (not a factory reset, only the settings) due to some problems. After that, my PS3 tells me for every account the password would be wrong. I can login on sonyentertainmentnetwork.com perfectly on my PC. Only my PS3 says it's wrong.

Need quick help dudes.

You must be typing it in wrong...

I'd suggest changing your password into something simple from sonyentertainmentnetwork.com.
If that does not work try creating another user and signing in through there, not sure what else to say
Have a great day

No guys, here's the solution. Found it out after a day by googling for hours. I did not found a solution to my exact problem or even anyone who had the same problem but whatever.
After you restore the default settings on a DEX system (like mine), the NP environment will be set back to "sp-int", the debug environment. This means that you can't login into PSN. Why it says that your password is wrong then, honestly, I don't know.
At least:
1. Debug Settings
2. NP Environment
3. Replace "sp-int" with "np"
4. Reboot
5. Login!

Anyways, thanks for the help.

If it is solved this thread should be closed..
