I did this cause I thought it was to enable psn on a lower firmware but I did what it said and it didn't work when I did l3+r3+r2 and so I went in psnpatch and I pressed the ps button and then did the combo and the I went to exit it and then my ps3 restarted when I exited and then it went through the coldboot but after the coldboot it usually shows the warning sign but it didn't show it when my ps3 restarted and it stayed like that and is still like that as I am making this post. can anyone help?
You can't go to PSN on lower firmware, only on current one. PSNpatch only masks CFW, so if you're on lower firmware PSN will ask you to update. You should have cobra enabled and install plugin from PSNpatch app, if I remember correctly. Then the combo will work. And check that plugins file on PS3 HDD.
