I bought a ps4 version 2.60 and i want to jailbreak. My ps4 asked me to update to 6.20 so before i update i search if there is any jailbreak for 6.20. I found some videos in the youtube so i update it.. Unfortunately after the update i tried to jaibreak but the videos were all fake... Is there any way to go back to 2.60? If i download the 2.60 software then boot into safe mode and reinstall 2.60 via usb???
