PS4 PS4 no power after enabling UART

[sguerrini97]

Hi guys, 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
