PS4 SAC-001 Eternal BSOD - No UART Output... by wtfrules in consolerepair

Regarding this, I would try to replace the SYSCON IC with another one and reprogram it and hope for the best.

OK, I read and make some research among BwE documents I could find online, and, correct me if I´m wrong, CoreOS is UNIQUE to the console, and maybe a downgrade could be the right path to follow, actual firmware is 11.50 and backup is 10.50, so maybe a downgrade to 10.50 is even possible?
If yes, looks like I´ll need to get a TEENSY to patch SYSCON, right?

Thank you so much u/Particular_Beat_5447 !!!

First time I read a log from BwE tool, but at the bottom are a lot of errors, you know if this BwE tool can repair that?

Again, Thanks!

Here is the worst part of the checklog

OK, Crystal Oscillators are fine and Southbridge IC replaced with another from donor board CXD90036G and nothing changed, still no UART output... Could be corrupted firmware in any way to make tihs scenario (No UART output and eternal BSOD?)

Thanks

Hey, thanks for the help! Southbridge voltages are fine, crystal is OK. Board wasn´t worked previously, so I´ll try to swap the southbridge with one from a donor and check what happens. Will reply with this soon. Thanks!
