Hacking Hardware Picofly - a HWFLY switch modchip

[Stonehearth]

What are the values of these resistors?

B is the recommended values and the one to use, tried and tested since the beginning by the people here and as the picofly guide will tell you.

And i dont know why you keep on insisting with other values?

I come with some updates about, let me present the results.

awesome
my switch came back on

Hi sergio can we talk via telegram about your findings to recover that OLED? @st0n3r_7

Hi sergio can we talk via telegram about your findings to recover that OLED? @st0n3r_7

Looking from your table, looks like the DAT0 line is problematic.
When you use 250 all OFW stuck, when you change to 100 OFW working.

Maybe the nvidia try to read from Dat0 and failed, so the stuck.

Is this oled? if it is and you use the flex method, thats already explain by itself.
If its not oled, try to reduce the dat0 resistor to 47 ohms.

The standard is 47 ohms CMD/CLK/DAT0. Reset no resistor.
I use CMD/DAT0/CLK as 100/100/47.


BTW the rst should be bridged (no resistor). I try use resistor before, and it doesn't give any differences. Its only pull the voltage down to reset the cpu cmiiw.

Left small chip with lots of fpcs is

2
47
47
221

Right bigger chips is

47

I'ts a Switch V1, updated results, no chance of victory by now.

I've been told that picofly on the v1 can damage the emmc chip. Is that true? I want to install a chip on a V1 and the picofly chips on ali are easier to install than the trinket ...

 

[Nephiel]

The picofly seems to me just as hard to install as the trinket? I'm curious about why you think it's easier.

IMO, it's a bit of a shame to picofly a vulnerable V1. Why force a glitch in hardware when there's a softmod method? Feels like kicking a door when you can just ring the doorbell.

With a payload pusher like the trinket, you don't force the hardware to do anything it wasn't intended to do. It's like having a doorman that sees you coming down the street and opens the door for you, there's no call for violence.

That said, if you're determined to avoid a payload pusher and go with the glitch method, all the *fly chips currently on ali are a lottery: little to no support, no QC, and who knows what you're getting. Better stick to openly supported boards like the Waveshare RP2040.

These or a very similar one are appearing on aliexpress. Nice quality flex though, clean cut and lines up well. The kamikaze connection looks promising but i havent used it. from vaalpaev store.

How do you achieve such a cleaning ? You have no trace of flux, no trace of IPA, everything looks dry and clean

Hi, they're as safe as all the other v1_patched, v2 or oled installs. Just make sure you have someone that knows how to mod properly.

well, with a chip installed on the inside of the console you're pretty much all set. no need to carry a trinket or anything. also waveshare rp2040s are the ones officially supported as picofly installs and are not that much more expensive compared to the aliexpress ones, especially when buying in bulk.

I meant the Trinket M0 and similar payload pusher chips that can be installed inside as well.

Hello everyone. I received an Oled Switch with a bad installation and with several problems. It is missing several components, including the capacitor, which is close to the 3.3V that I show in the image with the red circle. Could someone tell me what its capacity is? I thank you in advance. Greetings.

Would someone be so kind and tell me how much capacity this capacitor has? Please

When you want to mode nintendo switch oled

Some time People see white line on lcd cfw or ofw boot. (reson and some reson)

1.static from tip move to motherboard. Must use inti static tool.
2.no clean point
3.damge capacitor back of motherboard.(mosfet cpu) bad mosfet.
4.paste soldring move under nand or cpu from clk or dat0 adapter.
5.heat cpu or ram when you use heat gun to dat0 kimkaze.
6.damge dat0 point when you de soldring adapter more one time.
3.damge lcd conector when you try disconect meny time mistake with bad try bad tools.

according to what you say these are things that can also happen to LITE or classics, but I have never seen this on those consoles. it happened to me only on oleds but I tend to exclude the heat gun, never used, the adapter (I am kamikaze), the dirt ) I saw certain rubbish work perfectly, the flat (it happened to me on an oled where I worked only on one side)... in short, it can be all or nothing

Heat gun push soldring paste balls to under cpu or ram some time...

@rehius did you know what that means? long-short-short on data base?

Does anyone have more ideas? Need more info (CPU,RAM,SYSNAND)?

I'm tired with this console that represent 0,05% of my jobs and out of ideas.

It's an urban legend

So I’m currently working on an oled doing the kamakazi method. I keep getting =*** (emmc initial failure). I’ve cleaned everything and am getting the correct reading. Any help would be appreciated. Just checked and the switch still boots normal so I know I haven’t broken the trace.

Just installed a dat0 adapter to check that I have continuity between the two points and I do.

Resistor values? Which modchip? I had that same error once, and the cause was too much resistance on the CLK line (47ohm + the modchip had another 47ohm on board already).

And how do you solve it? Bridge de CLK line too?

I'm now on the 5th attempt according to recomendation on the forum.

 

[Nephiel]

No, I left CLK with a total of 47ohm (onboard) and it's working.
