Hacking Hardware Picofly - a HWFLY switch modchip

[QuiTim]

Do you have a diagram of it?

Did you use the flex cable or dual mosfets with wires?

Single mosfet with wires.
I posted the progress a couple of hours ago:

I am saying in diagram switch installation
no datasheet

No diagram, just some pictures. I used a small piece of kapton to hold it in place while i was soldering. Afterwards I put a bigger piece and placed back the shield.

question, i have NSO subs , games like fortnite and warframe then modding it....

will the sysnand be exact replica/copy of OFW? thats where to play legit games right?

The sysnand IS your OFW, unless you mod it. You take a backup of sysnand, then make an emunand on your SD card to do any modding if you want to go online with OFW.

in the upper mosfet you soldered 4 legs
and at the bottom you soldered 3 legs and left 1 for the CPU output?

ohhh, i thought sysnand CFW is like a copy of OFW, and emunand is copy of sysnand CFW.

this was my thinking of the situation. if i have unmodded OFW 14.0.0 then modded it therefor i have

OFW - 14.0.0 (can only be update to wifi)
sysnand - 14.0.0( can be updated to daybreak)
emunand-14.0.0(can be updated to day break)

Yes, all 4 upper ones are Drain, the first three on the lower side are Source and the 4th one is Gate (which goes to Pico).

Technically speaking, you have 4 possible ways to boot, it's like a lattice

	SYSNAND (OFW on eMMC)	EMUNAND (CFW on SD card)
No Mods (No Atmo)	A	B
With Mods (With Atmo)	C	D

A) is how your console boots stock with no hacks.

B) is how your console boots if you haven't modded anything but make a copy of your sysnand to your SD card called emuMMC or emuNAND

C) is how people get banned from Nintendo servers, by booting to official firmware, making mods without masking their console ID, and then their console tells on them to Nintendo's servers.

D) is how you do everything Nintendo doesn't want you to do, but you also should mask your console ID in this version, because otherwise it is an exact copy of your OFW that is on your sysNAND, and can get you banned as well.

In other words, if you're running mods, mask your console ID, regardless of which system you boot into.

do i need to use incognito to mask the id?

hello guys i have a few questions , i wanto to hack a mariko and a lite using rp2040zero , i got the flex cables and the 47 resistors so , do i need to remove the 3.3v voltaje regulator from the rp . I dont use online (cuba) so i can install the cfw to the sysnand ? . where i can find the diode readings to check my soder work

in other things i got 3 rolls of smalted coper wire , 0,09mm and 2 0,22mm the problem is the 0,22mm reads 0,4 ohms one and the other 1ohms the 0,09 reads 0,01ohms , what you recomend

 

[rehius]

do i need to remove the 3.3v voltaje regulator from the rp

I suggest to remove it after programming

so i can install the cfw to the sysnand

CFW (Atmosphere) is temporary, it is not installed anywhere. But in case of homebrews - sure you can install them on SysNAND if you don't need online

where i can find the diode readings to check my soder work

just measure the continuity between PCB points and rp2040 points. Diode readings are wrong because when everything is assembled you measure the rp2040 voltage drop, not the PCB one

the problem is the 0,22mm reads 0,4 ohms

could be bad contact with probes. I would still suggest to go for 0.22mm for the mosfet<->APU

im going to be using the hwfly flex cables , im good in microsoldering but better to be safe than F

this are the wires i go t, 1 of the 0,22 is copper the other is another aloy like golden

i see people using old ide cables , thanks for the help

 

[zehu]

friends, something happens if the firmware before installing the picofly is in the ofw 16.0.2

 

[AceCuba]

one last question and sorry for the inconvinence , i dont own a heatgun station at the moment , any good triks to remove the usbc port using flux , desoderwire and ironsolder

 

[rehius]

use whatever you like, both are fine for signal wires
IMO I would prefer the wire that can be tinned easier

it does not matter

the oficial fw should no matter as long atmosfere support that version

Pour much lead around the USB header, then touch the USB header with powerful iron, while holding it in tweezers

if you don't care, you can just tore it off with cutters / pliers

thnaks for all the help , a switch here is kind spensive so even i have fix a few , new proyects alwys gets my nervs jaajj i like to do all the research

i was thinking that if i cant ( saferemove) , in the end we can now update trow hekake , afeter the frist boot to hekake , what should i do , i have see people re updating the pico
