===UART Method=== :''For more information, take a look at [[PS4 UART Guide]].'' For this, you can use the UART method, to listen to the console, and see what it complains about. The pin is a debug pin coming from the syscon/southbridge, that can be accessed via UART. Firstly, you'll need to dump the flash using a programmer, then you'll need to use BwE's program to change the flag for UART functionality, reflash it, then you have unencrypted information coming out of the debug pin. If this step is not done, you will see nothing, except for a bunch of spaces in serial monitor.
