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.

BwE PS4 WiFi/BT Patcher & Extractor[edit]

WiFi/BT Results

Hello! This program, a micro version of my PS4 NOR Validator, is designed solely to validate and repair the WiFi/BT module of your PS4.
How do I know I need it repaired? Well if your controller does not sync anywhere but the safe mode menu then your module is corrupted.
Note: If your controller does not sync in safe mode, this program is not for you! You have a southbridge/usb port issue.
I have included a small sample of VALID patches for you to use, but you may have to source more yourself. Just place them in the /Patches/ directory with any file name.
If your patch isnt listed and you enjoy risk, my program will allow this. You can patch a mis-matched firmware for your WiFi/BT module.
Doing this will wipe c0020001.bin and its header from your PS4's NOR entirely and replace it with whatever you have chosen. I recommend you stick with the correct Torus version, which will be displayed on screen. Slim & Pro models are generally Torus 2.
If you hate risk but still want to patch, simply ask around for your matching patch file. Just quote the file size.
If you have found a patch that is not on my list, let me know at bwe@betterwayelectronics.com.au and send me a link to it. Feel free to use my EXTRACTOR to verify its validity and ensure proper extracting!
I will add any new patches to my program in future revisions.
