The firmware 3.20 disable otheros like 3.21 ? if not were can i get it?
AFAIR there was no official OFW 3.20, so latest with otheros is 3.15 http://www.ps4news.com/forums/downlo...at&id=8&page=2
Why not using CFW3.55 with otheros++ support?
There has been a 3.20 FW... but i was buggy so not long after 3.20 came 3.21. But 3.55 with OtherOS++ is a much better and stable option!
