== Wireless communication module firmware corruption ==

The Wireless communication module firmware is stored within the [[Flash-Main]] of the PS4 in a file designated C0020001. It is updated during the firmware updates of the PS4. This firmware is known to get corrupt ?how?, rendering the Wi-Fi and Bluetooth broken. This means that the DualShock controller cannot function in the XMB. However, the controller can still be used in safe mode as this is the only software of the PS4 that does not utilize the Wireless communication module firmware at all, 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.

How to know if the PS4 Wireless communication module firmware is corrupted? If your PS4 wireless controller (DualShock 4) does not synchronizes anywhere but in the safe mode (by USB).

Note: If your controller does not sync in safe mode, there is a Southbridge/USB port issue so you should fix Southbridge/USB before.

=== PS4 WiFi/BT Patcher & Extractor by BwE ===

[[File:Screenshot2.png|300px|thumb|left|Wi-Fi/BT Results]]

[[User:BwE]] has developped a PC program to aid in the validation, repair and extraction of the Wireless communication module firmware. It will use MD5, entropy and pattern analysis to determine if and where the module is corrupted. From here it will determine a valid replacement based on the PS4's expected module version and size. Should there be no matching version available the program will offer you the ability to patch a new header and new module. This methodology is risky, but if this is your only option then it is worth a try.

BwE has 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 is not listed and you enjoy risk, the program allows patching a the firmware of your choice.
