I have a problem with the PS4 model CUH-1216B. First, the blue screen crashed - connect the dualshock with a USB cable and press the PS button. After connecting it rains with a cable it did not respond to the PS button. I suspected that the system or disk was down. I checked the disk and it's ok. It doesn't go into this console to enter safe mode. When I hold the power button the console after the second beep just turns off instead of entering this mode. I had a second disk so I formatted it on FAT32 and put it in the console. I downloaded the latest update from the site and uploaded it to a USB stick. The console after the installation installed the system but there was still the same problem - the blue screen and plug it in and press PS, which the console did not respond to. So I decided to try installing the system again. Safe mode still did not work, so again the format to force the system installation. Well, now it looks like that when you try to install SU-41283-8 error crashes. I have not found any description of this error or the inability to enter safe mode.
