Hacking Hardware Picofly - a HWFLY switch modchip

[The3rdknuckles]

Just wondering... do you guys think my "A" resistor is donezo?

Hi guys. I've got a bad wiring/dead cpu error on this oled and after removing every mod component, I just get a black screen.
Reading from past messages, it appears that scratching the clk via might have broken it.
I don't have a green adapter to source clk from, so I was thinking: is there a spot where I can scratch clk from? Just like you would with dat0 in kamikaze

There is no way you have it fix from the bottom end up if CLK via broken from cpu source side.
You either remove cpu and fix the trace or fins way to recovery the trace to via from existing trace left outside the cpu edge.

Actually the trace on the cpu side looks just fine.
It's just that, reading from older posts, I kinda understood that it's possible to break the very inner part of the via that goes to deeper layers.
Or maybe I just completely misunderstood and the problem lies elsewhere?

Black screen could be anything.

It could be the screen dead (maybe corrotion).
Or the screen connector broken.
Or the emmc line broken (cmd / dat / clk).
Or power broken.
Or something else.

Are you disconect the battery wile you soldring point or soldring point and the connector is conect by mistake???

Black secreen not reson that clk is broken you can jumper it If there clk copper line you need microscope.

Desolder cpu need very good work or will kill it easy.

Read all point before you work on console.

Ok, to be a bit more precise, the Switch does power on but it doesn't progress further through its stages. That's why I thought it to be clk (for some reason I believed that dat0 would display a purple screen).
Every trace looks fine, but who knows? I'd like to test continuity from the back of the motherboard and I know where to find dat0, but what about clk?

Oook guys I've noticed something quite bizarre that might actually be the culprit.
Is it possible for some oled Switch to miss this capacitor?

Edit: It actually looks like it's an inductor and not a capacitor. I've got a donor v1 Switch. Does anyone know if I can source the same component from there?

It's used for the 3.3V regulator and it has a value of 1uH. Check if the inductor on V1 has the same value before replacing.

A broken Dat0 via while doing a kamikaze will result on a black screen when you power on the Switch. i can see that your Dat0 via is very well exposed (perfect circle) but what about the thin line wich goes to CPU? Are you shure you didnt broke it while drilling it ?
