PS4 no power after enabling UART

[Guest]

Hi, I have a PS4 Slim that shows no power after I tried to enable UART.
Before this it was working fine except for the disc drive.
I removed the NOR flash, patched the dump to enable UART and put it back on the motherboard.

After this process the PS4 acts like there's no power. I tried the power button, inserting a disc and using the joypad. No beeps/no leds.

It was my first time attempting this so I'm afraid I broke something on the motherboard while using the hot air station, but I can't see any obvious problem or missing component.

• I checked the caps around the flash for shorts to ground and they look good
• 12v, 5v rails are not shorted to ground
• NOR VCC not shorted to ground
• PSU is working fine in another console
• NOR flash is still good, I desoldered it again and was able to read its content
• Writing back the original NOR flash dump didn't fix the issue

What else should I check?
Thank you!

Update on the situation:

I've been sick the last couple of days so I didn't look too much at the console. Today I picked it up again and connected it to a TV, and everything is working fine.

I'll monitor it for a while but I'm still curious about what could've caused the no power issue

Re: PS4 no power after enabling UART

The problem with ps4 is that the source bridge is damaged. You need to replace the chip so that you can boot the device. and see the uart .
What type of board for your device؟؟؟
i can help you.
