I took my ps4 to a technician because I had no video output. He changed the integrated video chip, but was unable to reintall system. I am trying to do it myself, but for some reason when asked to insert the pendrive with the system software, i am unable to press the Ok button(controller connected to usb and working). On the other hand, all options in the safe mode are disabled but option 7. Edit: I am Adding images of the problem. https://imgur.com/a/muivaSJ
After Trying everything, found out that the problem actually was the “right“ pad button in the controller. Now a new error presented ce-35888-2. I will open a new question for this. Thank You EveryOne!
Did you tried to format the drive before you put it back in the PS4? Otherwise try another (empty) HDD just to test.
