Systerm Firmware: 4.31
System Model: 160 GB Slim PS3
What I do:
Steps taken to try to fix the issue:
I don't normally buy PSN stuff, but I'd very much like to buy Jet Set Radio since it's on sale for the '13 for 13', but I can't even do that. It's most strange that it would try to download a 26mb file, download 400% and yet then try installing with a 44mb file which is certainly much less than 400% of 26mb...
I'm having the same problem you are. My PSN Store and Home both show the title screen then just hang. Check if your PSN home hangs too. Maybe someone has an answer.
