I am in safe mode on my PlayStation 4 I would would chose the option #3 update using a thumb drive it update all the files on there it will get to 100% but, it turns off blue light then turns back on again you will see the black screen PS logo then it will go back to the safe mode again then it go back saying "connect the DualShock 4 using the USB Cable, and then press the PS button". This is the problem I am having I wish I know what to do for a few months now.
