Thanks for replying, jevolution! After I reconnect without proxy, it could not connect anymore (previous it could!). Re-do the wireless wizard many times..still same. Even reset the PS3 lol. I had closed the PS3 proxy server program... and even rebooted the PC and router. I'm using wireless.
Actually, the two methods are similar, except the part where we need to edit the file. For 2.30, do I need to edit the file:
A) AhmadkaX2's method:
B) Sacabonos's method:
For Sacabono's method, is it ok to have ImageVersion=000061f3?
I'm sure I did the correct steps...now i'm a bit afraid to re-do again after all the hassle to reverting back to non-proxy network.
Now the problem disappeared after I shut it down (also shut down the router for hours) and went to sleep LOL. But the default theme color is not black anymore. It turns out to be grey... I'm not sure why. Could this be the problem?
