Hacking Hardware Picofly - a HWFLY switch modchip

[Dee87]

Hey guys I need your help.
I got these two little things lost.
The photo was taken before I lost both of them...
Could you please tell me what they are ？（50k resistors？ or something else？）
Thanks.View attachment 367777

what switch model?

what switch model?

Oled.
Nearby the rst point

hello people, I would like to ask you a question, I made 3 switches with picofly and using 1 mosfet connected to the two cpu point capacitors, and I got a light blue led by the error code, it is a cpu failure, so I put 2 mosfets using a drain on each capacitor and it worked normally, my question is this problem is caused by using only 1 mosfet on both capacitors? what do you recommend? use the 2 mosfets or use only 1 mosfet in only 1 capacitor the wire I am using is AWG32, this error happened in 1 switch lite, 1 switch oled, 1 switch V2

Is necessary cut the raspberry pi pico or just remove the components?

All is about space the full pico will not fit inside without chopping a big piece of the backplate of the console. my advice is use a zero or little one raspberry board.

Well, the flex cable uses 2 mosfets so there must be a reason for that otherwise they would have just used one to keep the manufacturing costs down.
That being said, Rehius said that he is doing some research and on the next update the mosfet requirement will (most likely) be lower, so this will not be an issue anymore.
So for now the best thing to do is 2 mosfets on 2 caps which eliminates any possible issue on that point.

Thanks for the answer and clarification, I will do that and test further, thanks

Hi i finally managed to install rp zero but when i turm it on it lights up blue than changes to red and turns off. What it can be? In tutorial theres no anything about red light

I'll be back in I couple hours if nobody has gave u the value I'll measure them for u

Can anyone tell me what this is, I left the device turned off for a week, I went to turn it on today, the chip pulses white then blue and finally cyan and it seems to start Ofw but it just stays on this screen and restarting

Update to 2.67

Did you get red light when flashing? (just checking to see if your rgb is right).
Can you post a short video so we can see it
If its leaning toward purple color it might be the emmc connection

Rgb must be right i was solidering this pins i will post video when i get home

@rehius (or if anyone else knows), what components NEED to be left on the PZero for glitching? I know we can remove the port and regulator to make it thinner, but what about cutting the chip and\or moving components around, to make the whole package smaller? I have successfully cut it down before but now I'm wondering just how far I can take it.

I screwed up, accidentally i remove every component of the front face of the Rp2040, this still work? It’s already programmed.. the back it’s normal every component it’s there.

hi guys, I'm having problems with firmware 2.65, the chip lights up that the clk is wrong, but it's ok, the same thing happened to me yesterday and when I put flex instead of mosfet, it worked, now I have double mosfet placed but only connected to a capacitor, Is it necessary to use the 2 capacitors as in the flex?

 

[Jonas225]

It's still not working. Tried 2.66, 2.67 but no lock. Updated to 2.67 via toolbox, removed sd card.

Restarted to the "no sd card" screen, presses Vol+- to boot OFW but it blackscreens.

I also get slow emmc errors when backing up emmc. Maybe thats the problem?

Any other ideas?

Got it working now. Slow Emmc was caused by a too long DAT0 cable. Routed it originally around the CPU. No it is connected directly (~ 5cm shorter).

Slow Emmc fixed and thus OFW Black Screen fixed.

Recreated EmuNand and no longer package1 Error.

Thanks at all

if the cable was already short, just add one more resistor DAT0 solved

The cable should be as short as possible to avoid line interference.

led indicator and capacitors may be not required but the small chip in center of the board is flash chip (where the code store) is very important, Idk resistor is required or not

Okay i figured it out vcc cable was poorly soldered. now im fighting with mosfets coz one doesnt want to work

What is the latest tutorial for completing this installation?

I am looking for a guide that has the same layout as this one right here(I know its for the trinket):
