2. PS4 Unplug & HDD exchange
3. Create a folder on the USB flash drive called "PS4" pack in this then the folder "UPDATE" pure. (In capital letters!)
4. On the USB stick (min. 1 GB in size), the initialization file upload incl. Current update 1.76 (PUP file) down.
5. USB stick stuck in the PS4, PS4 switch in secure mode (just the ON button press for a few seconds)
6. PS4 initializing Select (menu item 7) and follow the instructions ...
Tips:
- Make sure the USB stick format to FAT32 (if this has a different format).
