It is updated during the firmware updates of the PS4. This firmware is known to get corrupt ?how?, rendering the WiFi 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. | ||
=== BwE PS4 WiFi/BT Patcher & Extractor === | |||
[[File:Screenshot2.png|300px|thumb|left|WiFi/BT Results]] | |||
[[User:BwE]] has developed a program to aid in the validation, repair and extraction of the Wireless communication module firmware. | |||
This program, a micro version of BWE PS4 NOR Validator, is designed solely to validate and repair the PS4 Wireless communication module firmware. | |||
How do I know if 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 is not 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 and its header from your PS4's Serial Flash entirely and replace it with whatever you have chosen. I recommend you stick with the correct Torus version, which will be displayed on screen. PS4 Slim and Pro models generally have Torus 2. | |||
If you hate risk but still want to patch, simply ask around for your matching patch file. Just quote the file size. | |||
Feel free to use BWE Extractor to verify its validity and ensure proper extracting! | |||
