The mosfet is reson and long wiers. Flux and lose dat0 point voltage. Sda scl can fix this error blue led blinking 4 time yellow light....

How can I Fix it? What should i do?

I just checked that if I don't connect the CPU flex to the chip, the error doesn't occur. I changed the flex for another one, but it remains the same. The moment I connect the battery with the CPU flex connected, the chip starts trying to glitch even if I don't press the power button. If I don't connect the flex, the chip only tries to glitch when I press the power button.

Got this offer on a local craiglist:
View attachment 341370 View attachment 341371 View attachment 341369

The seller says it's a new RP2040 Picofly based version modchip for Switch Lite and Oled, only.

What do you think about it, looks like it's a clearly fake, am I right?.. Or not?

It looks like a fake because, in my system, it looks different

Look at the date. That's the prototype.

The chip is try to glich but read all point in chip and motherboard some time mosfet is fulty and some time chip if you desolder the boton or type c port the heat move some resistor or crystal chip use microscope...

Having the ** code (two short yellow blinks)

Used the guide to figure out it's the RST connection.

I went to resolder and I noticed that the pad on the ribbon is gone... what are my options?View attachment 446150

Had the same problem, the soldering was fine.
That particular chip has a flex connector with 3V3 : D : A : C : B : GND, but the flex you are using has the 3V3 switch with the B, hence the error.
Some chinese suppliers are sending out the wrong lite fpc's, specially in the 3 in 1 kits.

I have two short flashes. I have the board removed from the console. I connect the processor flex, the cable from the 3.3V (I'm not connecting the other points, just individual cables), and then the battery connector. Immediately after this, the chip lights up blue and gives two yellow flashes.

The same thing happens if I only connect the 3.3V and RST to the chip.

Thanks. I guess I'll just try replacing both mosfets. I know some people have used a single one but I assume it's best just to go straight for using two again? I bought 10 so I have spares.

I've attached some photos of the cleanup. Still not perfect but it's better, at least.

Forget about 2 Mosfet. You can use only one and it will work perfectly. I cannot understand why there are still people thinking on complex instalation with 2 Mosfets.

You have clear pic you can add here???
You know cpu point read value is it 450 V or up or dowen????
