Hacking Hardware Picofly - a HWFLY switch modchip

[Mr Skinner]

I think you need to replace the "no beep" one

Is this resistor the same one used for the CMD -CLK and DAT0 points on the rp2040?

what's the reading in the diode mode on both sides of CMD resistor?

.387 No beep.

No, its not the same. I tracked the trace, that resistor is not connected to ground so it should not beep but it needs to have a specific resistance.
Maybe you can diagnose it as @Relon said in diode mode but I dont know what value is correct in diode mode.
If you can make a reading in resistence mode Ω we could know for sure if it need to be changed

hi everyone, i have successfully installed picofly on my nintendo switch lite. now i want to install it on my v2. i noticed picofly has new firmware with many changes. I would like to know if it will work well with only one mosfet (I noticed one mosfet can cause some errors)

sad...

Anyway, in Ω 20k scale, cmd resistor reads 4.69. This is a good value?
@Relon ?

That is good, the resistor is ok. We need to look elsewhere for the problem.
Did you try it on docking, just to rule out connector?

It works fine. You don't need two mosfets, ever, unless one of them is broken.

did you have any pictures of single mosfet pattern? the one in the V6.1 installation guide confused me a little bit

I ctually connected the charger directly to the device. But when smoke came out, it was just on the battery.
I also have this CLK island that I rebuilt before powering up. She is not grounded,
I used clear 3d printing resin, and its diode value is 700.

If 3v3 capacitor near charge ic chip it is 1uf 6.3V 0402

There are 2 0402 capacitors very close to each other, are they the same value?

.387 No beep.

in mine it was ~0.3 and ~0.7 on the other side (resistor next to CMD point)

 

[sleeperonair]

Can you please help with the indication?
==* CPU always reaches BCT check (no response to failure, check MOSFET) this is it?
in dialing mode, the processor shows 0 resistance, its okay?

Same of mine. Thx for response!

how you solder the flex?
3-4 should be soldered to use both mosfet

Resistance on sp1 and sp2 0.1 external and 14 ohm internal

[sleeperonair]

I mean the end of the flex there is 6 line. The middle part should be soldered together to use both mosfet.

only 3, i will try together tomorrow. Thank u

why only 1 is used and it works for them

This is what @abal1000x means

but since both caps show 14ohms, my two cents is that your flex cable is faulty.
