Hacking Hardware Picofly - a HWFLY switch modchip

hello again everyone! Are these resistors correct?

It is 47 Ohm.

Yes, those are correct

Does anyone know of any cpu cables that will be used instead of MOSFET?
I saw that the V2 cable is used in OLED and LITE versions. By the way, Mariko used V1 cable. Can't I use V2 cable in mariko?
Conversely, is V1 cable not available in OLED and LITE versions?
And V3 cable seems to be compatible in all versions, but the store doesn't sell it..

you can se uv mask , but i still think the flex is the way to go , more spencive but man safer

netflix should do a recap of this threat almost 300 pages , man this is easy 5 seasons

AIO Thread

alot of information is people asking for help and will xyz work.

I reach another time the No SD screen, but until tomorrow I will not have the SD to prepare It.

My problem is on if I press vol +&- in no SD screen, the Nintendo logo shows up, then nothing. Only black screen. What's the problem?

The first time I saw a loading square, but black screen too.

Any ideas?

GOT one TOSHIBA switch lite by hand, 47 ohm single MOSFET didnt make it.
BLUE-> PINK then OFW boot.
Tried double CMD, CLK,DAT0 to 2x47 ohm still same.
Tried 2.64 and 2.65, no success. I think I need to digging up some old info

Done the first PicoFly.

Double mostfet single resistor?

Double mostfet single resistor?

Will try. Can anyone share the nuke.uf2 file?

Guys, picofly is running well. but I don't do the UNLOCK.BIN
What is this? Need to do?

just did dual mosfet. V2.65_I and v2.65 both tried w/ 47 ohm resistor, still blue->pink-> OFW
I noticed if you add 2x 47 ohm on all cmd, clk, dat0 lines, I have 3s glitching time, slightly longer than 47 ohm setup. But still, no luck.

No as long as you have latest fw flashed and working, Ignore the UNLOCK.bin

For some reason I keep trying the 2.5_toshiba_fix but realized it wasn't ready for seeed Xiao rp2040 support. Looks like I have to wait for next FW

Is anyone going the mosfet route finding they don't work on SKHynix emmcs? Both dual and single mosfets?
But the flex works fine?

I just got the same behavior on V2 switch Mariko and switch lite where there is a blue light followed by green and the boot screen is OFW. The blue light does not pulse followed by a green light. It switches from Blue to green instantly. Both were SkHynix switches.

The first switch lite tried, don't know what the emmc brand was, but it worked the mosfet route.

However the flex cable works fine with the SKHynix emmc.

just flash firmware 2.65 no unlock needed.

After flashing the firmware what colour was the led?

My lite is a Toshiba and it runs fine with FW2.65.
I use rp2040-zero and all smd resistors are 47 ohms.
The wiring could not be made this short and clean.
Try using rp2040-zero and lengthening the emmc related wires.

HELLO HELP did picofly today and won't turn on, I remember I didn't shut it down before removing the back cover. Can anyone help??

Does your pc detect it if you plug it in?

 

[Dandan0404]

Let me try

Let me try, I already removed the picofly

No

 

[rv03]

is there a diagram for v1 flex uses on lite,v2,oled?

 

[Spore2]

In my case it was accidentally physically damaged during the modchip installation.

Since it boots into the IPL, the basic things like eMMC and CPU should be working. Looks like the power circuit is damaged somewhere

I've replicated my mistake. I think my mistake was scratching through the square pad on the cpu that is an alternative point for source on the mosfet. damn. Both units bluescreened. Crazy thing is that picofly boots.

 

[sergiochendry]

I think that the problem is in the bad soldering of the cable. So do as I do, unsolder the transistors and connect as in my drawings and everything will work. Good luck!

It is necessary, in the multimeter diode mode, to check the connection between points D and S, then touch the red "+" to point G, and black "-" to point D. And check that the values between D and S should change. Then we reset the transistor (we run something iron through it to close all the contacts) and check points D and S again, if the value has changed again, then the MOSFET is working. We do everything in Diode mode.

How about the D0 adapter
I see that D0 adapter looks like doesnt fit with the line
Is that normal?
