Power went out. Now Ps4 displays the following message: Ps4 Cannot Start. Attach Usb with 5.05 software or more.
Already tried that several times with the right file (900+mb) doesn't work. Tried removing HDD and checking it's functionality... It works perfectly.. I formatted it manually on PC and tried again still didn't work. What can I do to fix it?
Some guy in a PS store told me that there's a problem with the NAND which I didn't understand and said he couldn't fix it.
