I have PS4 slim fw 5.05 with wifi module ESP8266 and everything work great without any crash and problems, all new games works the only game wich is not work is Cyberpunk 2077. Also i have PS4 Pro on 7.55 and I would like to jailbreak him too. I read that everyone recommends that I go on 9.00 and use a usb key method. I do not like how this method works and my question is can i use ESP8266 wifi module like for my 5.05 slim and how this works on 7.55? My PS4 Pro stay almost two year unused on shelf, and i think it is time to activate him :-)
