Software Wireless BT[edit]

C0020001.bin[edit]

The firmware for the WiFi/BT Module is found within the Flash-Main of the PS4 in a file designated C0020001. Its location is 0x144200 and its length can be determined from reading the header information at the start of 0x144000. This is periodically updated during the firmware updates of the PS4 itself. This is the reasoning behind storing the firmware for the module within the firmware of the PS4 itself. This software is known to get corrupt and once it is will render the WiFi and Bluetooth useless. This means that controller cannot function in the XMB. However, the controller can still be used in safe mode as this is the only area of the PS4 that does not utilize the WiFi/BT Module, rather it only connects to the controller via USB. This problem is repairable, given you have a copy of the same firmware for your module. User:BwE has developed a program to aid in the validation, repair and extraction of the C0020001.bin for this sole reason.
