Hardware Failed picofly installation

[Fede12]

Hi, yesterday i tryied the kamikaze method on my switch, all points looked and measured good but after intsalling the picofly i first got purple screen and after changing the cmd resistor i just got no screen, this is the situation rn, hope someone can help me thx! (no screen also without picofly)
(ps: near the kamikaze i exposed another trace to test the cmd resistor continuity)

Almost ground away the CMD trace on the top pic, but doesn't look too bad. However, bottom pic shows you nicked the corner of the APU when cutting the shield and there may be damage to traces around that corner.
Also, there may be issues around the CLK point, can't see much with all the soldermask.

imma remove the mask but the clk is not grounded and has the same diode value of exposed one, oll check the cpu traces thanks

Trace is not fully cut, and OP has stated having tested continuity.

I haven't read everything, usually the problem is there. But for cross-checking, why not try it? Maybe it interferes with the reduced track.

the console get past purple screen and i have blank screen, i tryied booting without the resistor and purple screen showed up, do anyone know boot procedure to know whats wrong?

But what steps do you follow during installation? To avoid stumbling around in the dark after installing, I first run the kamikaze and perform the boot verification. Then I move on to everything else, which is simple. Which steps did you use?

i did everything without checking cuz im dumb, im strongly convinced i performed a good kamikaze tho

Yeah, doesn't look too bad from the pictures (that bridge is overkill)... Unless the DAT0, CLK or RST vias are damaged under the solder (unlikely), or some debris got under the APU, or the APU itself got lifted or knocked when the shield was cut near that nicked corner, all I can suggest is to check all the way around the shield, especially near the tabs, for any damaged traces.

there are none damaged, the cpu is a little scratched because my tool was too big but i didnt put pressure on the board

check your B point a small short there will cause all sort of weird issue, you'll be amazed a small short like that can prevent it from turning on at least from my experience.

Got same problem, I installed quicksolder PCB on CPU, and after do kamikaze, plugged battery and checked if it power on, it's ok, but after installing PCB of another points, it's got blackscreen, removed everything, still blackscreen.... duh You solved you problem?
