Ok. I updated to 5.50 GEN-D3 (still says GEN-B in system menu)
Then I got PSN network working with PSNlover.
I was able to download some DLC.
Then I updated my IRshell which asked me to run btcnfpatch.prx after installation for CFW 5.50GenD3
Now PSN network and in turn PSNlover are not working anymore.
Jeez...
