Hacking Hardware Picofly - a HWFLY switch modchip

[jkyoho]

Hello, yesterday I asked about whether it was possible to use a v2 Flex in a v1, I saw this image on the internet of what I want to do but opposite, a v1 Flex in a V2 and I wanted to ask, how do you think I should do the installation ? the top side of the v1 smd on the right side of the Flex V2 and the bottom side of the v1 smd on the left side of the Flex v2? Or would I have to do it the other way around?

pay attention to the mosfet Drain, Source and Gate connectivity you should tell this is the way when v2 flex fits to v1 CPU

Where did you find this? I need to to this (V1 flex on a V2) but I’m not sure the diagram is right.

V1 on v2 is easier. This is all the info you need.
You only need to solder the G(ate) from the top of the flex cable (2 middle pins)
Dont forget to solder the anchor because those are the S(ource) point.
Good luck

Hello, thank you very much for helping me, have you made that connection before?

Has anyone had an issue with the modchip just blinking blue for about a minute and a half and then red. Console was glitching fine, for two weeks. Will a reset of the chip work ?

someone has diagrams for Nintendo Switch Lite to see the points well

 

[wikisa]

guys why some of you wires transistor to two resistors? and someone to only one
btw can someone send a good quality photo of v2 motherboard solder points?

I'm honestly have no idea also. I asked the same question and I've got following response:

Some people have had problems with only using one and got it working when using two. I'm not certain if the number of mosfets has been the actual issue though - I think it's more likely that the first one just wasn't working properly. Anyway, you can always test with one and add another if the rp2040 gives you cyan light.

When I checked it with multimeter there is no resistance (except multimeter probes ofc) between these points so I believe that's no reason to do so (if there is however I would like to know ).

Here's my photo of my mosfet installment which is using only one side of capacitor:

Everything ofc works.

I think just connecting any of black dots to mosfet's source and any of red dots to mosfet's drain is sufficient:

switch oled?

You could try cutting like this.
It would minimise the risk of shorting something and it would fit better.
But please check the pictures carefully and do more research.

I have v1 and worked on lite(v2) and pretty confident with the flex pinout, you could tell exactly which goes where from this thread.

Good night everyone, my RP Chip arrived Today and I saw that the unlock_uf2 file no longer has it, I would like to know if I still need it or I just need to put the FW 2.6x file for picofly to work, another doubt can I use flex V2 in a lite and solder the two Flex points to the chip?

you don't need unlock.uf2 if you flash any fw 2.6+ on your rp2040

switch oled?

Yes

This has cost me an afternoon working on MOSFET. I installed it pretty well, using one and then two, but I wouldn't get a diode reading and logically I thought it didn't work. Dedee suggested I tried it out and turned out it worked perfectly. I guess there's no diode reading when using MOSFETs directly?

I was doing my Switch installation with a 0.3mm enameled wire, and I broke too many traces. I couldn't find 0.2mm anywhere near me. Luckily, BNTECHGO listed a one-lb 32 AWG in my local shop, Oh boy did it not make all the difference. Looks red and sexy too.

0.2mm wire is the way to go like many have here said.

 

[malgamer]

Yes

try to check your dat0 adapter, probably need adjust to get 0.7xx value

 

[carlozgd]

hi guys
while trying to use the CMD alternative point I damaged that resistance, could someone be so kind as to tell me what its value is
sorry for my english from google xD

 

[FreeLander]

Reporting my RP pico successfully glitching after being cut as per @rehius and @Dee87's diagram.

Looks nice for a proof-of-concept. I came to notice that the Dat0 point on RP Pico is very fragile so I engraved a trace right next to the RP's chip, this made me keep the other side of pins that would have been otherwise cut, but I needed the ground on that side to not make it messy next to all the resistors, not to say it doesn't look messy anyways lol.

Thank you @rehius and @Dee87. You guys have been very helpful and responsive.

HELP ASAP, I GOT PURPLE SCREEN, how to fix?

Others could confirm but I think this is because the resistor on point A was damaged. The value is 4.7k ohms. Try replacing it.
