Hacking Hardware Picofly - a HWFLY switch modchip

[deeps]

I remember seeing that but couldn't find it anywhere. What does it call?

The dat0 point is It not a small open arc, it is a closed circle. Should it be cut in the middle???

Is there any update with RP2040-Tiny?

Has anyone experienced tried it?

Yeah, thats not good
I should look something like this (picture)
Check here then here and then for a possible solution here

Thank you all. Here's a clearer picture.

Any further input is appreciated.
Dee, This is not my work. I'm inquiring for a friend who has this Switch.

Give it a proper clean and inspect it. If the trace is broken, it must be fix. There are two methods you can add a solder to see if it connects the both. But not recommend without proper skill.

Second Method which I personally prefer is that you should use a 0.1mm and connect the paths.

By removing the eMMC chip and soldering a wire to the third point? Is this how you do it?

There is a point on board. You have to grind up the board to add a Dat0 point. Right Now, I don't have a pic. But you can find it online. If I find I'll edit this post.

Because of these cheap one dat0 adapter, We can damage our emmc chip or may be corrupt it. See @QuiTim Post below for a nice quality adapter.

picofly 2.73 i have blue, short green, long green long green. anyone know what this code could be? i changed RPI 2040 zero(have only 2), changed wires, re solidered few times.

i have used 0.1mm wires, then dubule 0.2 wire

tried 2 mosfets, 1mosfet- same
tried 2, 47 Ohm resistor on data and clk…
anybody found solution?

it load OFW every time

Error: *== No eMMC CMD1 request (poor wiring, or dead CPU)

Edit: Check the wires with multimeter.
Also, try to press the reset button when joycon logo appears. If it shows No SD Screen, then solder the SDA and SCL wires.

guys please help, i successfully installed pico chip and im booting to hekate, but no matter what i try i could not boot to atmoshere, using the latest HATS files, tried to boot from Hekate to OFW but i got only black screen after the nintendo logo, error for atmophere is sometimes unable to identify package 1 atmosphere and Error Desc: std: :abort() (0xFFE)

what i did i do wrong, both switch lite and unpatched switch v1 with pico mod chip installed but same exact error cant boot to atmosphere

nintendo switch lite, removed chip, working normal.
checked points all Ok not used diode mode to check.

used 0.1wire, after i used 2wires for data0, clk etc. gnd awg30 wire…. same

soldered sda and scl no lack. Never tries presing reset after screen show , you mean shortin 1-2pins on side?

on one chip removerd port and buttoms, other have all aprts

It would seem that the RP2040-Tiny boards on the Waveshare site are no longer on back order!! ：D ：D ：D

Both with and without the USB port adapter!

Wonder if it now has the right resistors?

yes.The message I got is that it has been changed to 47ohm.

Excellent! Any recommendation of where to purchase them now? I guess only directly on the Waveshare site as the Aliexpress sellers won't have received them yet? I could be wrong of course

What is the Program ID?
Did you create emuMMC?
Go te Hekate and run emmc benchmark and take a photo of results.

 

[jmmc]

So we don’t need to add 47ohm to rp2040-tiny?

 

[Sainty]

Correct, as long as you actually do get receive the board with 47 ohm resistors on pins 27, 28 & 29.
You'll need to verify it when you receive it!

And the points are the same as rp2040-zero?

Thanks!

 

[Sainty]

Thanks!

I believe so. I'm far from an expert though. I'm sure someone will confirm or correct me

hello
do you think solder wick can absorb the lead solder on the RP2040 zero 4 leg ??
im having trouble remove the leg

im planning buy solder wick...
but kinda hesitate if it doesnt work, if the wick cant absorb it

sure add flux and a lot of low melt solder.......... still gonna be tough , but doable
