Hacking Hardware Picofly - a HWFLY switch modchip

[naldo29]

all point is conect and use back mosfet or flex and if you use hekate you can see all info for emmc chip and sd card???

What are you referring to when when u are talking about the flex or masfet. Im confused on what you are saying.

the back mosfet is one mosfet in the back of motherboard. the flex is on cpu sp1 sp2.

try to see emummc cfw make one and see if it working.


or the chip is fulty or some point is disconect or are you use picofly chip?!

this happened when i tried to go into sysnand atmosphere

The OLED models first shows the Nintendo logo and then the Nintendo Switch logo :

Glitching the OLED switch after camikaze results in a *=* (short-long-short) situation.
All diode readings are fine
I've already successfully worked on the camikaze several times
And I've seen an opinion that resistance should be added as a solution to a similar problem
Where should I add any resistance?
Where should I look?
Can anyone tell me about this?

What are the current resistors and what brand emmc is in your OLED?
Came across this picture today :
Definitely not the way to do it :

It's the first time I've actually seen the installation of Resistance.
Where should I connect the specifications of which resistance?
My NAND is Toshiba emmc. All the devices I worked on before were Samsung and SK. Is this causing the problem?
I've switched chips and tried installing again and still get the same symptoms (short-long-short)
There is no problem with installation, and the diode values are all normal.. someone please teach me

You installation can be perfect but there are some emmc brands that need some additional resistance.
In this thread it has been mentioned several times I recall, but we're already at page 835 now.

Here is another thread where the issue with the Toshiba emmcs is mentioned :

I presume this is still relevant but anybody correct me if it is not.

does any one has this issues ?
i booted successfuly into hekate 5 fist times
i tried to boot hos with 2.61.uf2
backed emmc, created emunand then when after inject hekate 6 bringme up to this issue
i trieed to clean the picofly with flash_nuke.uf2 but not luck at all

Have you got the answer ? I tried updating mine and got into this too, been searching on how to fix it, nothing worked.

Delete the existing Atmosphere, Config , Bootloader, Sept folder from your SD card
Extract the HATS pack to your SD card.
you can download the hats package from here: https://www.sthetix.info/hats/releases/
And please upgrade picofly to the latest version, no need to stay on 2.61.
Also don't forget to update us if it works

Hey after modchiping a switch lite the controls will work for 3-5 minutes then stop after leavening the console off for a while.

Any thoughts?
Thanks in advance!

Does the screen wake up from the sleep mode?
If not, maybe you need some extra resistor because of the type of emmc you have :

Yes everything works fine but the controls

Anything additionally installed like sys-clk, overlays, other modules?
Also the latest versions of all Hekate/Atmosphere and modules?
It might be a software issue, not directly related to the picofly.

Sometimes too much flux residue might cause weird behavior according to some other post here.
But then the issue would also occur without going into the sleep mode.
Is your picofly firmware also up to date?

The controls stop working in ofw and cfw. I cleaned the flux and the picofly is up to date.

If using an RP2040-Zero board, is it ok if I add the additional resistors no matter what, or are they only needed if I encounter issues? What I'm asking is that if I prep the chip with the extra resistors before installing it, can they cause other issues?

you can always add the extra resistors without issues. in fact good installs will work fine using both. from the history of this thread, 100ohm(or 47+47 ohms) resistances will have higher compatibility and increased chance to just work. there should be no issues when adding the extra resistors on every install.

 

[westleyaaj]

My emmc is samsung.
I have never seen anything about extra resistors in the guides I have seen.

Toshiba is the best Nand out of the all the Nands out there.

I did a kamikaze on a Toshiba Nand Oled recently with rp2040 zero original board (none hwfly) and I didn't even need to replace the cmd and dat0 resistors at all.

Any written instructions for the PicoFly OLV1 modchip soI can provide it to the installer? I bought this chip last year but it didn't come with instructions. I know it is the model in the video below so my backup plan is to give him the video and hope for the best.


This is what it looks like:
