It worked through the AL-AZIF's page that opens when we're using his DNS servers. I've clicked on 4.74 and then on bin loader. Then I tried to inject the browser.bin through PS4 Payload Sender app on my Android phone. The browser is unlocked now. Then I opened again his page and injected the ftp Payload and debug settings appeared, but after one minute (maybe a little more than a minute) my ps4 shuts down (probably a kernel panic).
