I'm gonna upgrade from fat to slim. I already got both consoles in my living room. However I got a serious problem now. I wanna sell my old fat console with 3.15 installed. But to deactivate my account (to be able to copy all content to the slim, and keep 5 activations) I need to connect to the PSN. Connecting to PSN means upgrade necessary. So I don't know what to do.
As the workaround doesn't work any more (fake 3.21 installer posted 2 days ago) this won't be an option (bans reported).
I don't know what to do. Is there any other possiblity to deactivate your PS3 without having to connect to PSN?
